Indexation bloat is when a web site has pages inside a search engine “index” that shouldn’t be listed, and might trigger points if not monitored and policed correctly.

It’s an especially frequent web optimization drawback and impacts all web sites, starting from small WordPress blogs to huge Hybris and Magento ecommerce web sites.

The extra severe circumstances of indexation bloat often happen on ecommerce web sites, as they have a tendency to make the most of user-friendly facetted navigations and filter lists, permitting customers to shortly establish the merchandise that they need.

I’ve seen examples first hand of straightforward Demandware and Open Cart web sites with just a few hundred merchandise having thousands and thousands of URLs seem in Google’s index due to the product filters producing URLs.

Why is indexation bloat an issue?

It’s a recognized undeniable fact that when Google and the opposite serps crawl your web site, they don’t crawl your web site in its entirety. Permitting and asking them to crawl pointless URLs wastes this useful resource.

If serps aren’t commonly crawling your “cash” pages and are as a substitute getting caught down different rabbit holes with out selecting up on updates, this might impression your natural efficiency.

Bloat may result in duplicate content material points. Whereas inner web site content material duplication isn’t as severe a problem as exterior duplication, it might dilute a person web page’s prominence and relevancy for search phrases if the web page itself as the major search engines aren’t positive which URL to rank for the phrases.

Figuring out index bloat points

One early indicator of index bloat is the variety of pages showing inside search engine outcomes.

It’s vital to notice right here that the variety of pages usually recognized utilizing the web site: operator inside Google and Bing search typically present totally different numbers to what you see in Google Search Console and Bing Webmaster Instruments — this isn’t one thing to fret about.

Web site monitoring

Whereas there are methods to resolve index bloat, one of the simplest ways, in my expertise, to take care of it’s to stop it from occurring in any respect.

By checking Google Search Console and Bing Webmaster Instruments on a month-to-month foundation, particularly at crawl information, you’ll be able to report what’s and isn’t common habits on your web site.

Irregular will increase, or spikes within the “Pages crawled per day” and “Kilobytes downloaded per day” may be indicators that Google is accessing extra URLs than it has been.

Likewise conducting a web site: search inside Google and Bing will allow you to see what number of URLs they’ve within the index, and also you’ll know roughly what number of pages your web site has.

How can I repair indexation bloat?

Figuring out that you’ve an index bloat problem is simply the 1st step, now you need to set up what’s inflicting the bloat.

These are a few of the commonest causes of indexation bloat, nevertheless it’s additionally not unusual to have a couple of of those causes.

  • Area URLs being served via each http and https protocols
  • Printable variations of pages inflicting a replica URL
  • Parameter URLs brought on by inner search
  • Parameter URLs brought on by product filters
  • Pagination
  • Weblog taxonomies
  • Session IDs in URLs
  • Injection of spam pages following a hack
  • Outdated URLs not redirected correctly following a migration
  • Trailing slashes on the finish of URLs inflicting duplication
  • UTM supply

Fixing with meta robots

A web page stage meta robots tag is my most popular methodology of coping with index bloat and is especially helpful if applied from a server stage throughout a number of pages directly.

Web page stage meta robots additionally take priority over pagination and canonicalization directives, in addition to the robots.txt file (until blocked within the robots.txt file).

These are additionally efficient at eradicating URLs containing parameters brought on by product filters, faceted navigations and inner search features. Blocking these within the robots.txt file isn’t all the time greatest as it could actually trigger some points between what totally different Google consumer brokers can see, which may negatively impression paid search campaigns.

Greatest observe could be to make use of “noindex,observe” — this manner any backlinks pointing to the web page will nonetheless go fairness onto the area.

Robots.txt File

Blocking URL parameters within the robots.txt file is each an amazing preventative and reactive measure, nevertheless it isn’t an absolute resolution.

All a Robots.txt file does is direct serps to not crawl a web page, however Google can nonetheless index the web page if the web page is being linked to internally or from exterior websites. If you realize the place these inner hyperlinks are, add a rel=”nofollow” to them.

Canonical tags

Self-referencing canonicalization is usually greatest observe, other than on bloated URLs. Ecommerce platforms, like Open Cart, can create a number of URLs for a similar product and class.

Including a canonical tag to the headers of the pointless product and class URLs pointing to the “most important” one will assist serps perceive which model of the web page needs to be listed.

Nevertheless, the canonical directive is simply a directive, and may be ignored by serps.


Pagination points can come up from weblog submit and weblog class pages, product class pages, inner search outcomes pages; mainly any ingredient of a web site that has a number of pages.

As a result of these pages will comprise the identical meta info, serps can confuse the connection between them and will determine it’s duplicate content material.

Utilizing rel=”subsequent” and rel=”prev” pagination markup will assist the major search engines perceive the connection between these pages and, together with configuration in Google Search Console, determine which of them want indexing.

Utilizing Google Search Console’s URL parameter software

The URL parameter software can be utilized to inform Google what particular parameters do to content material on a web page (i.e. type, slender, filter). Like different strategies beforehand talked about, it’s good to ensure you’re not by accident requesting Google to not index URLs that you really want within the index, and to not specify a parameters behaviour incorrectly.

Google classifies your parameters into two classes; energetic and passive. An energetic parameter is one thing that impacts content material on a web page, so a product filter and a passive parameter is one thing like a session ID or a UTM supply.

This could solely actually be used as a final resort and used appropriately at the side of different strategies, in any other case this might negatively impression the area’s natural search efficiency.

Earlier than utilizing this software, you should definitely learn Google’s official documentation and steering.

The URL removing software

Relying on the authority of your area, Google might take some time to acknowledge and filter out the URLs you need eradicating. After you could have applied one thing to inform Google to not index the URL once more (a web page stage meta robots tag), you’ll be able to request that Google removes the URL from index through Google Search Console.

That is solely a short lived measure as it can solely conceal the URL for 90 days from Google search outcomes, nevertheless it doesn’t have an effect on Google crawling and indexing the URL.

That is good to make use of when you don’t need customers having the ability to discover sure pages, however every URL must be submitted individually so this isn’t an amazing resolution if in case you have extreme index bloat.

Index bloat ensuing from a hack

Now, clearly in case your web site has been hacked, index bloat is unquestionably not going to be a precedence concern. However the bloat from a hack could cause points for the area.

The beneath screenshot is of a Swiss (.ch) area that operates inside Europe, weeks after a hack:

The web site itself solely has round 50 pages, however as you’ll be able to see Google is presently indexing 112,000.

Because of this, amongst different issues, these 50 pages of product and product info pages at the moment are misplaced amongst hundreds of hacked URLs, so any updates to those pages might take weeks to get seen – particularly in case your web site doesn’t command a big crawl price range.

One other indicator of this generally is a sudden improve in search visibility (for irrelevant phrases):

I’ve labored on web sites beforehand the place this has been the primary indicator. While operating a routine month-to-month test in Google Search Console, a web site that dealt in christening robes had began rating for “low-cost NFL jerseys” and different American sportswear phrases.

These visibility spikes are sometimes short-lived, however can destroy the belief between Google and your area for a very long time, so loads may be mentioned for investing in cyber safety past https.


Lowering index bloat doesn’t occur in a single day, so it’s vital to stay affected person.

It’s additionally vital to place in place a course of or framework, and giving possession of mentioned course of to somebody to conduct frequently.
