When we do SEO, we usually focus on producing new content. Let’s write a new blog post, open a new category, create a new page.
But after a while, hundreds or even thousands of old pages start to pile up on the site.
I think from that point on, this question becomes at least as important as producing new content:
Do we really need all of our existing content?
Some content needs to be updated. For some, it may be better to merge it, redirect it or remove it completely.
Is being old a problem on its own?
No.
If a piece of content written in 2018 still answers the user’s question correctly today, I won’t change it just because it’s old.
For example, a good piece written years ago on a basic topic like “What is USB?” may still be doing its job.
But a piece titled “Best phones of 2023” doesn’t have the same value in 2026.
So for me the issue isn’t the age of the content; it’s whether the information is still valid.
Why does content lose traffic over time?
A page can get good traffic for years and then start to decline. We usually call this content decay.
There may not be a single reason. Competitors may have created better content, the user’s search intent may have changed, the information in the content may be outdated, or Google may have started showing different types of pages for the same query.
For example, an article titled “Best free SEO tools” may have had great traffic in 2022. A few years later, some tools may have shut down, some may have become paid and new ones may have appeared. If the article stays the same, its traffic can slowly drop.
That’s why I don’t think my first reflex with an old piece that’s losing traffic should be “Let’s add a few more words.”
First I try to understand why it dropped.
Where can we start?
When I review old content on an existing site, I especially like to look at Google Search Console.
For example, you can open the last 16 months and ask these questions for a page:
- Are its impressions falling?
- Are its clicks falling?
- For which queries has it lost position?
- Are there keywords it used to get traffic from but no longer shows up for?
Sometimes you’ll see that the page isn’t completely dead. It still gets impressions, but its rankings are slowly slipping.
I think that’s one of the best candidates for an update.
What does updating mean?
When I say updating, I don’t mean changing the date on the content and republishing it. You actually need to update it.
For example:
- Changing outdated information
- Removing sections that no longer apply
- Adding new questions
- Filling in missing subheadings
- Refreshing images
- Fixing broken links
- Reviewing internal links
Sometimes you change 10% of the content. Sometimes only the URL of the old article remains and the content is almost completely rewritten.
What if several pages cover the same topic?
This is where another problem starts.
Over the years, a site may have created three very similar pieces like “coffee machine tips”, “best coffee machines” and “coffee machine recommendations”.
If they all answer the same user intent, they can start competing with each other in Google’s eyes.
In that case, instead of writing a fourth article, merging the three pieces into one strong page can make much more sense.
This can also solve the keyword cannibalization problem we touched on in Chapter 13.
Duplicate content doesn’t always mean copied content
When people hear duplicate content, most of them think of copying content from another site.
But very similar pages can also appear on your own site.
For example, on an e-commerce site, the same product can end up with many URLs through different parameters like ?color=black, ?color=white and ?sort=price.
These URLs may look different to the user, but to Google they may be serving largely the same content.
Or, over the years, similar blog posts may have been written on the same topic.
What matters here isn’t only whether the texts are word-for-word identical; it’s whether the pages really answer a different user need.
If they don’t, you may need to consider merging, canonical tags or, in some cases, removal.
Do we have to keep every old piece of content?
I don’t think so.
If a piece gets no traffic, no impressions and no backlinks, offers no value to the user and does exactly the same job as another piece, there may not be much point in keeping it on the site.
Systematically reviewing and removing low-quality content or content that’s no longer useful is called content pruning.
For example, if 500 blog posts have built up over the years but 150 of them got no impressions in the last 12 months, have no backlinks and largely repeat other content, that group can be reviewed separately.
But the most important word here is: systematically.
Deleting hundreds of pages overnight because they don’t show up on Google is not content pruning. I think you first need to make sure the page really has no value.
Always check before deleting
A page may get little traffic today but may have been very strong in the past. Or it may get no traffic but have important backlinks.
That’s why, before removing a page, I look at at least these:
- Organic traffic
- Search Console impressions
- Keywords it ranks for
- Backlinks
- Internal links
- Its value to real users
I especially wouldn’t want to delete an old URL that has backlinks without thinking it through.
We deleted the page, now what?
This is where a 301 redirect can come in.
For example, we merged three similar pieces and created one strong piece. Instead of simply leaving the old pages as 404s, setting up a 301 permanent redirect to the new page they relate to is often the better choice.
Another example: if a product is no longer sold, a new model of the same product has replaced it and the user’s need really is the same, it can make sense to redirect the old URL to the new model.
But redirecting every deleted URL to the home page isn’t the answer either. The page we redirect to needs to be truly relevant. If there’s no relevant equivalent, a 404 can sometimes be the better option.
We’ll go into redirects in more detail on the technical SEO side in Chapter 23.
Sometimes it gets better results than new content
I think this part deserves special emphasis.
We sometimes see a site publish 20 new pieces of content every month while its organic traffic doesn’t grow. Because the problem isn’t a lack of new content. It may be that old content repeats itself, has become outdated, or that the site is bloated with unnecessary pages.
In a situation like that, instead of writing 20 new articles, reviewing 50 existing old pieces, updating 10, merging 5 and removing 3 can get far better results.
I think this is one of the nice things about SEO.
Sometimes growth doesn’t come from adding something new, but from fixing what’s already there.
How do I decide what to do with old content?
I roughly think in terms of four options:
Update: When the topic is still valuable but the information is outdated. For example, if an article on the best phones of 2024 still gets traffic, instead of deleting it completely, it can be refreshed with 2026 models, current prices and new comparisons.
Merge: When several pages answer the same user intent. For example, if coffee machine tips, best coffee machines and coffee machine recommendations answer the same need, they can be merged into one strong piece.
Redirect: When there’s a more accurate and relevant page to replace the old one. For example, if a new model has replaced the old product and the purpose really is the same, a 301 redirect can be considered.
Remove: When the page really produces no value. For example, there may not be much point in keeping an announcement page that was created years ago, gets no traffic, has no backlinks, is out of date and is already covered better on another page.
I don’t look at a single metric for any of these decisions. Because even a page with 10 visitors can be very valuable in some industries.
Once again, what matters is what value the page creates for the user and the business.
I think the biggest mistake in content management is thinking our job is done the moment we publish an article.
In fact, content needs maintenance like every other part of the site. Some of it needs updating, some strengthening, some merging, and sometimes what no longer works needs to be removed.
Producing new content is part of SEO. Managing existing content well is at least as important.
