Chapter 31: How Do We Measure SEO Success?

Last updated: November 1, 2026.

In SEO work, one of the hardest things is sometimes not doing the work but correctly measuring whether the work we did was successful.

Because “traffic went up” isn’t success on its own. “Rankings improved” isn’t success on its own either. In fact, sometimes an SEO project can become far more successful commercially while traffic goes down.

In an SEO project, the real question should be:

Is the SEO work actually contributing to business goals?

To understand this, we need to evaluate metrics like rankings, visibility, clicks, traffic, conversions, revenue and return on investment together. I think tying SEO success to a single KPI is one of the biggest mistakes.

1. Is a ranking increase success?

It’s usually a positive signal. But it isn’t enough on its own.

For example, you moved from position 23 to position 4 for a keyword. At first glance that looks very successful. But that keyword’s monthly search volume might be 20. For another keyword, you moved from position 11 to position 7, and it might get tens of thousands of searches a month. The commercial impact of those two ranking gains isn’t the same.

You also need to look at the keyword’s search intent. Being first for “what is SEO” and being third for “SEO agency pricing” may not produce the same commercial value.

That’s why I always evaluate ranking data together with three things:

• Search volume
• Search intent
• Business value

2. Rank tracking

Rank tracking is one of SEO’s basic measurement methods. We regularly track the keywords we’ve chosen and see how their positions change.

But there’s a common mistake here too. We choose 100 keywords. Then every week we look at ranking changes like +3, -2, +5, -1.

I don’t think it’s right to manage SEO like watching the stock market every day. Rankings can fluctuate naturally. What really matters is whether the overall trend is going up or down.

It can be more meaningful to track groups like these:

• 1 to 3
• 4 to 10
• 11 to 20
• 21 to 50

If we had 120 keywords in the top 10 last month and 180 this month, we can say there’s been an overall improvement in visibility.

3. What is visibility?

Visibility is one of the measures that tries to capture, in a single overall metric, how visible we are for the keywords we track. Tools like Semrush build their own visibility scores for this.

For example, visibility went from 8% to 13%. That can be a useful signal that overall ranking performance has improved.

But again, be careful: this isn’t an official Google metric. It changes depending on the keyword set you track.

If you’re tracking the wrong keywords, your business may not grow while visibility goes up. For example, you might rise for hundreds of informational queries and fall for queries close to purchase. So visibility is useful, but you shouldn’t make decisions based on it alone.

4. Can CTR be a measure of success?

It can. For example, your ranking didn’t change, but you worked on the title and meta description.

The ranking is the same, but you’re getting 50% more traffic. That’s a serious SEO gain. If we measure SEO success only by rankings, we miss this.

But as we discussed in Chapter 29, we can’t evaluate CTR independently of position and SERP structure either.

5. Organic traffic

This is one of the most commonly used SEO KPIs. If organic traffic went up, that’s usually good news. But again, the same question:

Which traffic went up?

For example, organic traffic went from 100,000 to 150,000. 50% growth. Looks great. But if all of the growth came from a piece of content titled “2026 public holidays” and your business sells B2B software, the business impact may be very limited.

In another project, traffic goes from 10,000 to 11,000. Only 10% growth. But if most of those 1,000 new visitors came to product pages, pricing pages and service pages, the business value may be much higher.

That’s why it’s very useful to split organic traffic, where possible, like this:

• Informational content
• Commercial pages
• Categories
• Products
• Branded traffic
• Non-branded traffic

6. Can revenue go up while traffic goes down?

Yes. We experienced this very clearly with a real client.

The client had been working with another SEO agency for a long time. I knew the owner of the company and explained how working with us could be useful.

At the end of the first month, an interesting picture emerged:

Organic traffic dropped about 10%.

But:

Revenue rose about 180%.

Naturally, the client’s first question was: “So why did traffic drop?” 🙂

The previous agency had actually done a lot of things on the technical side. The site wasn’t bad overall. The problem was more that the work hadn’t been tied closely enough to the commercial strategy.

For example, the site was getting serious traffic from a piece of content about volleyball. But the business didn’t sell volleyball shoes. That traffic looked great in the report but contributed nothing to sales.

On the other side, there was content about basketball shoes, but it hadn’t been given enough care. Users were coming to the page but weren’t being guided to the products. At the most basic level, the page didn’t even have a strong call to action (CTA) to take users to the relevant products.

Instead of just trying to grow traffic, we started fixing user intent, the relationship between content and products, and the conversion path. In the end, total traffic dropped a little, but the rate at which the right users converted into sales rose sharply.

I think this is one of the best examples of what SEO success means.

Less traffic, much more revenue.

That’s why seeing a traffic chart going up in a report doesn’t make me happy on its own. The real question is:

Are we bringing the right people to the right place?

7. The goal of SEO isn’t maximum traffic, it’s the right traffic

The previous example actually sums this point up very well.

SEO work can sometimes shrink the areas where the site gets irrelevant traffic. That may look bad at first glance. But SEO may have become more successful if, at the same time:

• Commercial pages are growing
• Conversions are rising
• Add to carts are rising
• Lead quality is improving
• Revenue is rising

I think “organic traffic” isn’t the goal but a means. The goal depends on the business.

8. Branded and non-branded traffic

We mentioned the branded / non-branded filter in Search Console in Chapter 29. This distinction is especially important when measuring SEO success.

For example, the company ran a big advertising campaign. Brand searches rose 100%. Organic traffic also rose 50%.

Writing “Organic traffic rose 50%” in the SEO report may be technically correct. But SEO may not be the main reason for this growth.

So you need to evaluate the questions Did branded traffic go up? and Did non-branded traffic go up? separately.

If there’s a very large increase in branded queries, you should especially consider that it may be the result of Google Ads, TV, social media, influencers, PR or other brand investments rather than SEO.

That increase is still valuable. It may even have positive effects for SEO. But you need to credit the success to the right channel.

9. What is a conversion?

A conversion is a valuable action we want from the user. In GA4, these actions are marked as key events. It depends on the project:

• In e-commerce: Purchase
• At a service company: Form submission, phone call, WhatsApp, quote request
• In SaaS: Demo request, free trial, sign-up
• On a media site: Membership, newsletter, page views, ad engagement

In most projects, this is where we start to see the real value of SEO work more clearly.

10. Why can conversions drop while traffic rises?

For example:

Traffic rose 50%. But conversions barely moved. In this case, you need to examine the quality of the new traffic.

Maybe we gained a lot of informational traffic. Maybe we started appearing in the wrong countries. Maybe the offer on the page doesn’t match the expectations of users coming from the SERP.

That’s why evaluating SEO success only by “traffic went up” is risky.

11. Low traffic, high commercial value

We also talked about this in Chapter 10, on search volume.

For a B2B client we’ve worked with for years, daily organic traffic can be around 30 to 40 visits. At first glance you might say, “That traffic is very low.”

But the machines they sell cost about 20,000 euros. A single right lead can cover the cost of months of SEO work.

So:

30 right visitors can sometimes be more valuable than 30,000 wrong visitors.

In an SEO report, you always need to put the business model next to the traffic figure.

12. Why is tracking conversion rate important?

Looking only at the number of conversions is sometimes not enough. For example:

The number of conversions went up. But the conversion quality of incoming users went down. This can show us there may be a problem in:

• The traffic source
• The content intent
• The landing page
• The offer
• The user experience

Conversion rate isn’t SEO’s responsibility alone, but it’s very useful for understanding the quality of traffic coming from SEO.

13. SEO return on investment (ROI)

Return on investment (ROI) is one of the strongest ways to measure SEO’s commercial return.

Simplified formula:

(Gain from SEO - SEO cost) / SEO cost x 100

For example, if:

• SEO cost: 100,000 TL
• Profit from SEO: 300,000 TL

then:

(300,000 - 100,000) / 100,000 x 100 = 200%

ROI is 200%. But in real life, the calculation isn’t always this easy.

14. Correctly attributing SEO revenue is hard

A user found you on Google. They looked around the site. They left. A week later they came back directly. Then they clicked your Google Ads ad. Then they called the sales team. A sale was made.

Who does this sale belong to? SEO? Google Ads? Direct? The sales team?

In fact, they may all have contributed. That’s why attribution is quite a complex topic in digital marketing.

When calculating SEO ROI, instead of only asking “Who made the last touch before the sale?”, you also need to think about “What role did SEO play in the customer journey?”

15. How do you measure ROI in lead generation projects?

In e-commerce, measuring sales and revenue is relatively easy. But in B2B projects it’s harder.

For example, 100 forms came from SEO. Of those 100 forms:

• 40 were genuinely qualified
• 20 received a quote
• 5 became sales

If each sale is worth 500,000 TL on average, SEO’s commercial contribution becomes far more meaningful.

That’s why an SEO report shouldn’t end with Analytics. If possible, it should be combined with CRM and sales data.

16. Lead quality should be measured

The SEO agency says in the report, “We brought in 300 leads this month.” The client says, “280 of them were useless.” The two sides are using different definitions of success.

I think, when possible, it’s very useful to split leads like this:

• Lead
• Qualified lead
• Opportunity
• Sale

That way we can see not just the number of forms but the real commercial quality.

17. Why can sales drop while rankings rise?

This is possible too. For example:

• We may have risen for the wrong queries.
• The price may have changed.
• A competitor may have run a campaign.
• The site may have a conversion problem.
• The product may be out of stock.
• The sales team may be calling leads late.
• The mobile payment process may be broken.

SEO isn’t the whole business on its own. So before saying “Rankings rose but sales are falling, SEO failed,” you need to examine the whole system.

18. Is revenue SEO’s only success metric?

Not always. For example, on a news site the goals might be:

• Page views
• Ad revenue
• Subscriptions
• Returning users

For a newly launched brand, these might matter:

• Brand visibility
• Appearing for non-branded queries
• Reaching new markets

On a B2B site, qualified leads may be the main KPI.

That’s why KPIs should be defined before the project starts. Otherwise, we start inventing success criteria after the project is over.

19. How should SEO KPIs be chosen?

I like to think about KPIs in a few layers.

I think a good SEO report shows as much of this chain as possible.

20. Not every KPI carries the same weight

At a B2B company, “Page views rose 30%” may not be very important. But “Qualified leads rose 20%” can be very important. On a media site, it may be exactly the opposite.

That’s why I’m not a big fan of ready-made SEO report templates that ignore the industry. The report should be shaped by the business model.

21. Bounce rate

Bounce rate has been a heavily used metric in SEO reports for years. But it has very often been misread.

A user came from Google, read a blog post for 5 minutes, got the answer they were looking for and closed the site. Is that a bad user experience? No.

So automatically interpreting high bounce rate = bad SEO is wrong.

In GA4, bounce rate is the inverse of engagement rate. Still, it needs to be interpreted according to the purpose of the page.

22. Engagement rate

With GA4, engagement rate became one of the more meaningful metrics.

A session can be counted as engaged if, for example, it lasted a certain amount of time, a key event occurred, or more than one page was viewed.

But again, it needs to be interpreted according to the content type. If a user checks the weather and gets their answer in 5 seconds, a short visit isn’t always bad.

23. Dwell time

This is one of the concepts often discussed in the SEO world. Roughly, it’s used to describe the time between a user arriving on your site from a search result and returning to the SERP.

But there’s an important distinction here:

Google doesn’t give us an official dwell time metric in Search Console.

It isn’t the same as the session duration we see in Analytics either. So you shouldn’t draw firm conclusions like “Dwell time is 3 minutes, so Google will rank us higher.”

The concept can be useful for thinking about user satisfaction, but I don’t report it like an official SEO KPI.

24. Don’t treat user behavior metrics as direct ranking factors

In SEO, people sometimes make very definitive statements like “Google dropped us because bounce rate was high” or “Our ranking went up because dwell time increased.” Drawing cause-and-effect relationships that clearly is risky.

Analytics data gives us an idea about user experience, but it isn’t right to treat every Analytics metric as a direct Google ranking factor.

I use these more to understand the question Is the page doing its job for the user?

25. Can A/B testing be used in SEO?

Yes. It can be very useful, especially on large sites.

For example, you have 10,000 product pages. You try a new title structure on 5,000 of them. The other 5,000 are the control group. Then you can compare changes in CTR, clicks and visibility.

We can call this the SEO split test approach. It can be much healthier than changing a single page and saying, “There was an increase, so it must be because of this.”

26. Can every SEO change be A/B tested?

No. SEO tests are different from classic web A/B tests. We can’t show Google two different random versions of the same URL. Usually, test and control groups are built from groups of similar URLs.

So these kinds of projects can be better suited to SEO testing:

• Large e-commerce
• Classifieds sites
• News sites
• Projects with many similar templates

On a 30-page corporate site, running an A/B test for every change may not be practical.

27. What should an SEO report look like?

I think the biggest problem with SEO reports is that they contain too much data. A 60-page PDF. 200 charts. 50 tables. But in the end, the client still doesn’t know the answer to this question:

What happened in SEO this month?

I prefer to think about the report more simply:

• What did we do?
• What changed?
• Why did it change?
• What was the impact on business results?
• What will we do next month?

If there are answers to these five questions, the report is largely doing its job.

28. Which metrics should an SEO report include?

It depends on the project, but for example it might include:

• Organic clicks
• Branded / non-branded visibility
• Organic users
• Number of top 3 / top 10 keywords
• Performance of important landing pages
• Conversions
• Qualified leads
• Revenue
• Work completed
• Technical problems
• Plan for the next period

But rather than showing 30 different KPIs, it’s better to choose the KPIs that actually help us make decisions.

29. A report shouldn’t consist only of good news

An SEO report isn’t a marketing brochure.

If traffic dropped, we should write it. If a competitor passed us, we should write it. If the work we did didn’t produce the result we expected, we should write it. But alongside that, there should also be:

Why we think it happened and what we’ll do about it.

The client can already open Search Console and see that the chart went down. Our added value isn’t hiding the chart, it’s explaining it.

30. Why is it important to keep a record of SEO work?

For example, on May 15:

• We changed the title structure.
• We set up 301 redirects.
• We built an internal linking system.
• We refreshed the category copy.

Three months later, traffic went up or down. If we didn’t record what we did, it becomes hard to understand cause and effect.

That’s why I find a change log very useful in SEO work. Even a simple Excel file will do:

• Date
• Action taken
• Pages affected
• Expected result
• Actual result

Months later, it becomes very valuable.

31. How long does SEO take to produce results?

There’s no single answer to this question. Let me explain with two different examples.

One of our students had a site in a low-competition industry. We made a few small on-site changes. Within about 4 hours, we saw some keywords rise by around 10 positions.

In another project, progress was very slow for about 6 months. Two steps forward, one step back, almost like an old Ottoman marching band. Then, with changes on Google’s side, the site made a serious jump.

Both projects are SEO. But their conditions are completely different.

That’s why it isn’t possible to give everyone the same answer to “How many months does SEO take to produce results?”

32. Separating short-term and long-term KPIs

Measuring ROI in the first month of a new SEO project may not always be meaningful. First we can look at leading signals like these:

• Technical errors
• Indexing
• Visibility
• Impressions
• Early ranking gains

Later, these come into play:

• Traffic
• Leads
• Sales
• Revenue

Expecting all SEO KPIs to improve at the same time may not be realistic.

33. SEO goals should be realistic

Let’s imagine a newly launched site. The competitors have:

• 15 years behind them
• Thousands of referring domains
• Hundreds of thousands of pieces of content
• A strong brand

The client says, “Let’s get into the top 3 for every keyword within 3 months.”

That isn’t a KPI. It’s a wish.

A good SEO goal should be set based on:

• The current situation
• Competition
• Resources
• Budget
• Time

Otherwise, even very good work can look like a failure.

34. Percentage increases can also mislead

For example, organic traffic rose 200%. It looks amazing. But it may have gone from 100 to 300.

Another project went from 1,000,000 to 1,100,000. It only grew 10%, but it gained 100,000 new visitors.

That’s why it’s useful to show the percentage and the absolute value together.

35. Losing traffic isn’t always failure

This is exactly what happened with the client I described in section 6. Traffic dropped about 10%, but revenue rose 180%.

The reason was that instead of reaching more people, we focused on reaching the right people and connecting them with the right product.

I think that’s why, in an SEO report, you need to ask “How much did we increase the value of the traffic?” just as much as “How much did we increase traffic?”

36. A drop in indexed pages may not be a failure either

We talked about this in Chapter 25 with the Filmler.com example.

Instead of sending all of roughly 450,000 cast and crew pages to Google, we chose to index the pages that had content and offered real value. Fewer URLs are indexed. But the strong pages perform better.

In this case, “The number of indexed pages dropped” isn’t a failure metric. It can be the result of the right strategy.

37. Comparing with competitors

Comparing SEO success only with ourselves is sometimes not enough either.

For example, we grew 10%. Good. But if the market grew 50%, we may actually be losing market share. Or we dropped 10%, but if the whole industry dropped 40%, we may have become relatively stronger.

That’s why competitor visibility and market trends can also be included in the evaluation.

38. Can Google Ads and SEO support each other?

We need to make an important distinction here.

On the agency side, we observe that clients who actively use Google Ads or other advertising channels often see their SEO performance develop more strongly. There may be a few sensible indirect reasons for this:

• More people get to know the brand.
• Branded searches may increase.
• People may visit the site more often.
• Users may later search for the brand directly.
• Because content reaches more people, the chance of earning links and mentions may increase.
• Brand trust and conversion rate may rise.

But an important correction is needed here:

Running Google Ads doesn’t directly improve organic rankings.

Google officially states that its advertising systems and organic ranking systems are separate, and that advertising doesn’t affect organic rankings positively or negatively (Google for Developers).

So saying “Google ranks us higher organically because we advertise” isn’t correct.

I see this more as a holistic marketing effect. Advertising may be bringing the right users to the site, growing brand awareness, increasing branded searches and strengthening the business’s digital footprint.

In short, advertising doesn’t give SEO points directly, but good marketing activities can strengthen the environment SEO operates in.

And it doesn’t have to be Google Ads. Social media ads, TV, PR, influencers, offline advertising and events can increase brand demand in the same way.

39. Don’t credit growth in branded searches directly to SEO

I care about this point in particular.

Let’s say searches for “brand name + product” rose 150% in three months. Writing in the report “Thanks to SEO, branded searches rose 150%” isn’t always correct.

This increase may have come from activities in the same period like:

• Google Ads
• Social media ads
• A TV campaign
• PR
• Sponsorships
• Influencer work
• A new store opening

In fact, in most cases a sharp rise in branded searches shows the success of other marketing activities more than SEO.

SEO may still have contributed; for example, it matters that the right pages appear when users search for the brand, that the site has a strong presence in the SERP, or that it meets search demand well.

But you shouldn’t confuse the channel that creates demand with the channel that captures it. That’s why I think reading branded and non-branded performance separately is very valuable.

40. The highest level of SEO success: business impact

I think this sits at the very top of the KPI chain. Thanks to SEO:

• Are more customers coming in?
• Are better-quality customers coming in?
• Is customer acquisition cost going down?
• Is revenue going up?
• Is the brand becoming visible for new queries?
• Is dependence on paid advertising decreasing?
• Are new markets being reached?

If one or more of these is happening, SEO is producing real business value.

I think leaving SEO at the level of “We’re first for 10 keywords” undervalues the work we do.

41. Google Ads and SEO can be evaluated together

We may be spending a serious budget on Google Ads for a particular commercial query. When SEO work also gets us to strong positions on the organic side, we can evaluate the two channels together. Maybe:

• Our total organic + paid visibility grows.
• Users encounter the brand more often.
• We can optimize the paid budget for some queries.
• Search terms on the Ads side can give us SEO content ideas.
• SEO queries can add new keywords to Ads campaigns.

But let’s underline it again:

Google Ads itself isn’t an organic ranking factor. Google states this clearly (Google Help).

Even though the two channels have independent ranking systems, they can complement each other in a marketing strategy.

42. The cost of SEO isn’t just the agency invoice

You need to think about this when calculating ROI as well. SEO costs can include:

• Agency
• SEO tools
• Content
• Software development
• Design
• PR
• Team time

For example, the monthly agency cost might be 50,000 TL. But with content and development, the total investment might reach 100,000 TL.

For a real ROI calculation, you need to use the real cost as much as possible.

43. Don’t credit everything to SEO

Another mistake is attributing every positive result to SEO.

Sales rose 40%. But in the same period:

• Prices were cut.
• A TV ad aired.
• An influencer campaign ran.
• A new product launched.
• The Google Ads budget doubled.

In that case, saying “SEO increased sales by 40%” would be too bold a claim.

I think in reporting you need to separate what we know from what we’re estimating. An SEO report shouldn’t be prepared to write a success story but to understand what happened as accurately as possible.

44. What do I look at when assessing SEO success?

It depends on the project, but in general:

• Is non-branded visibility increasing?
• Are rankings improving for important queries?
• Are impressions increasing?
• Is traffic going to the right pages?
• What’s the organic traffic trend?
• What’s the quality of the traffic?
• Are conversions increasing?
• What’s the lead quality like?
• Is there a contribution to revenue and profit?
• Are new referring domains coming in?
• What’s the technical health like?
• Where do we stand against competitors?
• Has the work done produced results?

But above all of them is this question:

Are we getting closer to the business goal we set at the start?

Wrapping up

We can’t measure SEO success with a single number.

Rankings may have risen but traffic may not have come. Traffic may have risen but conversions may not have come. Conversions may have risen but profitability may be low.

On the other hand, revenue can rise 180% while traffic drops 10%. The remaining pages can become stronger while the number of indexed pages falls. Branded organic traffic can rise while the real reason is a successful advertising campaign.

That’s why we need to see SEO as a chain:

Visibility → Clicks → Traffic → Engagement → Conversions → Revenue → Business Value

Not every project focuses on the same point in this chain. But we need to get as close to the outcome as possible.

I think the most important question in a good SEO report shouldn’t be “How many positions did we move up?” but “What did our SEO work bring to the business?”

When we can answer that, we can start treating SEO not as a technical marketing activity but as a real investment.
