Gone are the days when you could easily hack search engines by loading a page with keywords and creating artificial backlinks.
Today, Google is consistently rolling out changes to its algorithms to reward quality.
Unlike the past, if you have low-quality pages on your website, it can negatively impact your overall ranking.
What’s a low-quality page?
It’s one that isn’t used or visited, is full of duplicate content from other pages, has thin content or very low engagement in the eyes of Google. Some people call these “zombie pages”.
Is it ok to remove low quality content like this? Yes!
Here’s the thing:
It’s entirely possible that you have dozens, hundreds, or thousands of low-quality pages on your site — in the eyes of Google — and you might not even realize it.
We call this problem index bloat.
It happens when Google has indexed a lot of URLs for your website that it views as low-quality.
In this article, we’ll show you:
- An example of index bloat
- Common causes
- The exact steps you can take to see if you have a problem
Note: We can help you spot and fix issues on your website that are harming your overall ranking. Contact us here.
Index Bloat: A Real-life Example
We recently started working with an eCommerce client and discovered something fascinating (and troubling) as we did our standard checks to evaluate their site.
After talking to them, we expected the site to have somewhere around 10,000 pages.
When we looked in Google Webmaster Tools (now Google Search Console), we saw — to our surprise — that Google had indexed 38,000 pages for the website. Find this chart here: Web Tools > Search Console > Google Index > Index Status.
That was way too high for the size of the site.
We also saw that the number had risen dramatically.
In July of 2017, the site had only 16,000 pages indexed in Google Analytics.
What happened?
How a Hidden Technical Glitch Caused Massive Index Bloat
It took a while to figure out what had gone wrong with our client’s site.
Eventually, we found a problem in their software that was creating thousands of unnecessary product pages.
At a high-level, any time the website sold out of their inventory for a brand (which happened often), the site’s pagination system created hundreds of new pages.
Put another way, the site had a technical glitch that was creating index bloat.
The company had no idea their site had this problem, which is common with a site that has a technical glitch.
For eCommerce sites that automatically generate new pages for products, brands, or categories, things like this can easily happen.
It’s one common cause of index bloat, but not the only one.
Other common causes include:
- Pages with too little original content
- Old blog posts, news releases, or case studies that get little to no traffic
- Search pages that get accidentally indexed by Google
Don’t think you’re safe just because your list of indexed pages looks like this:
Even if the overall number of pages on your site isn’t going up, you might still be carrying unnecessary pages from months or years ago — pages that could be slowly chipping away at your relevancy scores as Google makes changes to its algorithm.
The good news is: it’s relatively easy to identify and remove pages that are causing index bloat on your site.
We also have a free tool you can use that will help.
How to Identify and Remove Thin Content and Poor Performing Pages
Here’s the step-by-step process we use with our clients to identify and remove poor performing pages:
(1) Estimate the number of pages you should have
Estimate to the number of products you carry, the number of categories, blog posts, and support pages, and add them together. Your total indexed pages should be something close to that number.
(2) Use the Cruft Finder Tool to find poor-performing pages
The Cruft Finder tool is a free tool we created to identify poor-performing pages. It’s designed to help eCommerce site managers find and remove thin content pages that are harming your SEO ranking.
The tool sends a Google query about your domain and — using a recipe of site quality parameters — returns page content we suspect might be harming your index ranking.
Mark any page that:
- Is identified by the Cruft Finder tool
- Gets very little traffic (as seen in Google Analytics)
These are pages you should consider removing from your site.
(3) Decide what to keep and what to remove
For years, you’ve been told that adding fresh content on your site increases traffic and improves SEO. You should be blogging at least once a week, right?
Well, maybe.
If a blog post has been on your website for years, has no backlinks pointing to it, and no one ever visits it, that old content could be hurting your rankings. You should remove that outdated content.
Recently, we deleted 90% of one client’s blog posts. Why? Because they weren’t generating backlinks or traffic.
If no one is visiting a URL, and it doesn’t add value to your site, it doesn’t need to be there. It’s using up crawl budget for no reason.
(4) Revise and revamp necessary pages with little traffic
If a URL has valuable content you want people to see — but it’s not getting any traffic — it’s time to restructure.
Could you consolidate pages? Could you promote the content better through internal links? Could you change your navigation to push traffic to that particular page?
Also, make sure that all your static pages have robust, unique content. When Google’s index includes thousands of pages on your site with sparse or similar content, it can lower your relevancy score.
(5) Make sure your search results pages aren’t being indexed
Not all pages on your site should be indexed. The main example of this is search results pages.
You almost never want search pages to be indexed because there are better pages to funnel traffic that have better quality content. These are not meant to be entry pages.
This is a common issue.
For example, here’s what we found using the Cruft Finder tool for one major retail site: over 5,000 search pages indexed by Google.
If you find this issue on your own site, follow Google’s instructions to get rid of search result pages.
We recommend reading their instructions carefully before you remove or noindex these pages. They include nice details on that page about temporary versus permanent solutions, and when to delete pages vs. using a noindex tag, and more. If this gets too far into “technical SEO” for you, feel free to reach out to our SEO team for consultation or advice.
The Results and Impact on Traffic and Revenue
What kind of impact can index bloat have on your results?
And what kind of positive effect have we seen after correcting it?
Here’s a graph of indexed pages from a recent client that was letting their search result pages get indexed — the same way we explained above. We helped them implement a technical fix so those pages wouldn’t be indexed anymore.
In the Google Analytics graph, the the blue dot is where the fix was implemented. The number of indexed pages continued to rise for a bit, then dropped significantly.
Year over year, here’s what happened to the site’s organic traffic and revenue:
3 Months Before the Technical Fix
- 6% decrease in organic traffic
- 5% increase in organic revenue
3 Months After the Technical Fix
- 22% increase in organic traffic
- 7% increase in organic revenue
Before vs. After
- 28% total difference in organic traffic
- 2% total increase in organic revenue
This process takes time.
For this client, it took three full months before the number of indexed pages returned to the mid 13,000s, where it should have been all along.

Hi Chris, I have been exploring the idea of pruning useless pages and reducing index bloat.
I had a question. Once you have identified such pages, do you simply add a noindex tag to them? Are these pages deleted? Redirected?
BTW, really nice article- I’ll be using the Cruft Finder tool 😉
Hey Gurbir… Good question. There are lots of ways to “prune” a page once you’ve identified it isn’t a good current target for your SEO efforts. Our older article on Moz about pruning eCommerce sites is a good place to start. It also contains a link to again a bit older but still relevant overview of our content audit process. We plan to update both these articles soon.
Its extremely good and very helpful for me.Thanks for sharing this great post.
Chris, Thanks for the article. I had a question about low-value pages and whether they should be kept. Some argue that the larger a website, the better. With user engagement now a ranking factor, it seems logical that poor performing pages be removed.
Hi John,
As with many things SEO, I’d say it depends on a number of factors. Also ‘removing’ a page can mean a couple different things. For example, eCommerce sites wouldn’t want to 404 product pages if the product was still in stock. Low performing product pages are typically candidates for a noindex tag. There could also be the case of near-duplicate product pages if a product were available in multiple sizes and/or colors, and the CMS didn’t have the proper functionality to combine multiple URLs into one. In this case we might use canonical tags if there weren’t sufficient search volume to justify different pages for every size/color.
If the poor performing page is strategic content (blog post or similar), we’ve had success by using the “Remove, Improve or Consolidate” strategy. If there are multiple pieces of content on the same or similar topic, they can sometimes be consolidated into a single, more authoritative post. We also often improve posts, which include things like improving keyword targeting and expanding the length of the content (don’t forget to update the DateModified meta tag). Finally, we have rolled out a strategy to 404 pages that just aren’t performing (little to no traffic over a period of time) – for one client we 404’d 90% of their blog posts that received little traffic and saw a boost in rankings, traffic and revenue to their foundational content (category & product pages).
Hope this helps!
Hi there, did you update the article mentioned in this reply comment?
Thanks
I am not sure whether to use a redirect or not, but I am going to consolidate some pages on my website.
Hi Janice,
It’s usually a good idea to 301-redirect URLs that have been consolidated to the URL to which you consolidated – especially if those pages were indexed and/or received any traffic. Don’t forget to also update your internal links so they don’t point to redirected URLs!
Hi there,
I have a client with a few thousand blog pages of thin content, 300 words or less. According to GA the vast majority do not get any traffic (or something like one visit a year).
The client is an agency with only about 50 substantive pages, and thousands of “deadwood” blog posts, some dating back 10 years.
About 1% of these thin blog pages get minuscule traffic and yet another 1% have a small handful of links pointing at them, but none of any quality
So I’m just curious if you think it makes more sense to noindex all of these thin pages or to remove and 410 them.
Might be nice to retain a few of the pages that have minimal activity but I don’t think it will reallly help or hurt much.
Would you foresee any issues of taking this agency site from a few thousand indexed pages down to about 100 or less?
Greatly appreciate your thoughts here and keep up the quality content!
Thanks!
Hi John, good question. Typically we pull a years worth of GA data AND backlink data from AHrefs or some backlink tool. It’s important to ensure any pages you’re going to prune – whether 404/410 or using the noindex tag – don’t have backlinks pointing to them and haven’t driven (much) traffic / revenue.
A few thousand low/thin quality content pages sounds ripe for the pruning. There may be value in a couple other options…
– Republishing posts with enhanced content and better keyword targeting
– Consolidating similar posts into a more authoritative post
– Combine multiple ‘date based’ URLs into more of an evergreen page, for example, if there’s a post about the XYZ conference from 2015/2016/2017 etc. making it more evergreen could build the strength of the page(s) over time
– Remove (404/410/noindex); noindex is a popular option for eCommerce sites where there are many products that aren’t receiving traffic, or maybe have the manufacturers description and need rewritten – but the product is still for sale. If the page doesn’t have links and isn’t driving traffic, noindex doesn’t make as much sense. Just get rid of it.
But to answer your overarching question – these pages that aren’t driving any traffic aren’t providing the site with much value, and very well could be holding the ~100 quality pages back.
I agree, it could be worth keeping some pages that drive traffic – and I would make sure those visits aren’t leading to leads/revenue – if so you’d want to keep them… it just depends on how much traffic you’re willing to give up. Hope this helps!
Hi Chris
I run a page where we sell self-written articles by users. We have around 26.000 papers online now, and I see of course that google does not like ALL of them. I would say that about 3000-4000 do not receive visits from google. We look for unique content and plagiate check everything of course, but some content is just not very interesting in googls eyes (sometimes not interesting just now, but later)
Do you think I should simply NOINDEX pages that for example did not get a view in the last 3 months?
I sometimes see, that a page that had no interest/visitors for lets say 2-3 years, suddenly receives a lot more visitors from google (lets say the thematic becomes interesting again, like an article about the “2004 hurricane” so I am nervous about “DELETING” these articles completely. I see the internet also as an “archive” for older things, not just an archive about the last 2-4 years. (website is 12 years old now)
Any suggestion what to do with pages that have unique content but receive no visitors for several months/years? I could NOINDEX the article page, but could put them together on a “group of more articles”, where 40-50 of them are put together (but that overview page does not make sense at all, just overview pages of noindexed articles)
Hi Bodo,
Here are some thoughts and questions…
– How are you making money, from advertising? Do you sell products / services? Have these 3-4k pages that do not receive any traffic generated you any profit?
– What guidelines are users given for these self-written articles? Is keyword targeting considered at all? Can the keyword targeting on the posts be improved?
– Not knowing what the site and articles are about, or how the site is structured, one possibility could be to “topic bucket” the articles, putting them into categories and sub-categories. Then, build out pages with unique content that target these topics and link to all the related articles.

Hi Chris,
Does this tool work only on PHP based ecommerce sites? I am trying to run against java based ecommerce sites(on platforms like IBM WebSphere, Hybris, ATG) and it doesnt seem to work as expected. Thoughts?
Thanks,
NP
it should work with any ecommerce site regardless of language or platform. That being said I can see the tool is currently broken. We’ll have our devs take a look and make a fix as quickly as possible.
the CRUFT Finder tool is now working again. Sorry for the hiccup!
Hi, this post is great and the comments have given me some actionable tasks to start cleaning up old content on my site, GameSkinny.com. We are a news and reviews site for video games. As such, we have a wide swath of content types: news, reviews, lists, opinions, and features. We have staff writers and freelance writers and have been around d since 2012.
Some of the content, as has been suggested, could be consolidated, such as X beat horror games for X year, etc. However, some pieces, such as some news pieces for example, can’t really be updated as they were, say, on a release of a get or a the closing of a studio, etc. Some have very few total views, say in the 100s. Should these be culled completely or updated as best they can be?
Over the past two months, we’ve updated our interlinking strategy as well, writing to get content and writing copy with interlinking to other articles in mind. I think it is too soon to say if the strategy has been working, but it seems logical.
I suppose my main question is this: as a media site that has an extensive archive, what would be the best way to cull underperforming articles so Google doesnt penalize the site? Is it worth culling old, out of date news pieces, for example? What would you suggest? Thanks!
Hi Jonathan,
There’s a lot here! And without more information it’s tough to give one specific recommendation.
The pages you mention certainly could be worth pruning. There are sometimes a benefit to older news style pieces – if people are searching for that type of historical information – if they aren’t, they are probably good candidates fro pruning. You could also try to breathe new life into the pages by updating them, adding content, consolidating similar pages into one and updating the LastUpdated meta tag when you do. You could also “topic bucket” the pages – perhaps by game name – and build ‘hub’ style pages for specific games or groups of games. This would help the pages become more crawl-able, and in conjunction with things mentioned above, could help drive more traffic to those pages. But if the articles are old, out of date and nobody is searching for the content they contain, yes they are likely worth pruning.
Be sure the pages don’t have links before you prune! Hope this helps.
Chris
My question is when I deleted my post search console show 404 technical issue. how I overcome this issue. can I disavow the all link and remove it. I don’t find any option. can you please answer this brodlye.
Your post was really helpful.
Hi Jemes,
It’s OK to have 404s showing in search console, this won’t raise any red flags. No need to disavow anything. You should, though, make sure the URLs returning a 404 weren’t receiving much traffic or have any inbound links. If they do, 301-redirect them to the closest related page.
Does google penalize your website if you simply delete posts without deindexing first?
not at all. if you deleted posts without redirecting, meaning the user would receive a 404 error, that is totally normal and acceptable assuming it was on purpose.
thanks!
Great post, exactly what I was looking for. I’m in the position where I followed that advice of writing a blog post every week or so for an e-commerce site and years later have lots of similar posts on the topic that aren’t great. So I’m just culling out all the pages that don’t get traffic or have external links. My question is should I stagger out removing the pages over a period of time or should I just ‘unpublish’ them all at once? Would be approx 60-70 pages out of 200 total. Thanks!
Hi Mike,
If the pages aren’t getting any traffic or conversions there shouldn’t be too much risk in pruning the pages at once.
Hope that helps!
Mike
I have a “deal blog” that was running 20-25 deals per day of very thin, time sensitive deals. It’s a wonder I rank for anything on Google, actually.
Of the 24k posts I am guessing that 23,500 need to be deleted.
Is there a tool that can help me make a list of which posts to delete that you know of?
I have a developer that can maybe even do it in one fellow swoop if I can tell him which ones i want gone.
Any ideas, greatly appreciated!
Hi Kate,
It sounds like what you are looking for is more of a content audit tool than a CRUFT finder tool. Your coupon pages we probably wouldn’t consider true CRUFT but if they weren’t getting traffic and have no incoming links they need to be pruned. I’d recommend conducting a site crawl that pulls in GA, GSC, and link data all into one spreadsheet. Then I would set a threshold for traffic and links and prune any page that is under that threshold. You can find our basic process outlined here: https://moz.com/blog/content-audit that should help.
Thanks!
Mike
Hello Chris. This is my first time on your blog. I was looking especially for this topic.
Here is my situation: I have an affiliate website with around 300 pages. I think at least 30% of those pages never received search engine traffic. I am thinking about deleting all of them or merging them with other pages.
What would you do in my case? In either way I plan to 301 redirect them. However I see you 404d the pages of your client. Why choose 404 instead of 301? I see only disadvantages doing 404.
I’d like to mention that my pages are all above 700 words long. I don’t think this counts as thin content.
Also I have this weird problem: My site is authoritative enough. Whenever I write about a topic, the article will appear in the top50 at least. For any keyword. Even of the hardest two word keyword. However I have an article that doesn’t tank for it’s keyword. Which is really weird because content-wise it’s the highest quality post from all. It’s long enough. I simply cannot find the problem why my article doesn’t rank. The keyword difficulty is easy enough.
What is even weirder: another one of my pages ranks on #44 place. But that page doesn’t even have the keyword in it, only the company name. What do you think the problem could be? Should I completely rewrite the article?
Also there is no duplicate content or noindex or anything else. Page speed is also fine. Page is in sitemap and indexed in search console. I am only linking internally to the page that is not ranking.
Sorry for offtopic
Hi Chris, You talk about low quality pages negatively affecting ranking. So is it the case that low quality pages with a very low page authority due to no traffic or backlinks and poor content negatively affects the overall domain authority? Would de-indexing low quality pages with a low PA help to increase the overall DA, therefore increasing ranking in google searches?
Hi Phil,
If a page has no traffic or backlinks AND it has poor content it is a good candidate for removal from the index. Doing this does not increase your DA, but it does help improve your overall site quality and crawl budget.
I have just removed lots of pages from the index which are no longer relevant (which I have deleted from the site, old category pages and paginated versions).
no other big changes have happened to the site in months.
However, since doing this, within a couple of weeks we have just had a 30% reduction in organic traffic. Is it possible that fewer pages in the index has triggered a threshold for an algorithmic penalty? for example, we always had spammy links arrive at our site (like everyone does), but never disavowed because there was never an impact on rankings.
Perhaps now we have fewer pages in the index, the spammy links make up a larger proportion in ratio to the pages in the index and therefore an algorithmic penalty has occurred?
Any help on this appreciated
Hi Robin,
I don’t think that is quite how it works re: spammy links making up a larger proportion. If you removed paginated pages from the index it is possible Google no longer has a click path to your products. In addition, if you deleted pages that had good links and or traffic that could also lead to a decline in traffic.
Hi Mike,
Great article. I really enjoyed reading this. Which brings me to a question…
If the website is showing offers. (In my case – cottages website). The business has seasonal and off-season prices. and each package has an individual page. For e.g.: Winter deals – 20% off.
Since it’s seasonal, does it mean the page should be unpublished when the season has passed or still keep it on the site all the time?
Than you!
Hi Karan,
Ideally you wouldn’t need two different pages for this. A single “evergreen” page where the content changes would probably be the best approach. If that won’t work, you’ll probably want to leave both pages published and indexable year round.
Hi Rob,
We typically choose 404 when there isn’t any valuable content on the page to merge with another page. Otherwise it probably makes sense to merge pages and 301 redirect.
no it doesn’t sound thin, but it still might be low quality, irrelevant, etc.
