What It (Actually) Is & Easy methods to Repair It

Many individuals consider that having a number of pages about the identical factor confuses search engines like google and leads them to rank the “mistaken” web page.

Within the phrases of Patrick Stox, this complete concept is “preposterous.”

He’s proper. Having a number of pages about the identical factor can result in surprising or undesirable rankings, however it doesn’t at all times imply that one thing’s mistaken or wants fixing. Nevertheless, it may well sometimes sign a chance to consolidate content material to enhance rankings and natural efficiency.

On this information, you’ll study:

Key phrase cannibalization is when a number of pages on a web site goal the identical or related key phrases and compete towards one another to harm the location’s natural efficiency.

For instance, let’s say now we have two pages about technical search engine marketing. If we may get extra natural site visitors general by combining the 2 pages into one, that’s a cannibalization problem. The existence of these two pages is consuming away at our natural efficiency.

Key phrase cannibalization is dangerous. But it surely’s essential to do not forget that you solely have an actual cannibalization problem when a number of pages goal the identical key phrase and damage a web site’s natural efficiency. 

Provided that pages are likely to rank for a lot of key phrases, that’s not at all times the case.

For instance, let’s say that now we have two pages focusing on the identical key phrase. One among them ranks #1, however the different web page (that we’d want to rank) is nowhere to be seen. You possibly can argue that that is textbook key phrase cannibalization as a result of one web page is seemingly “cannibalizing” site visitors to the opposite web page. 

However even when that’s true for site visitors from this key phrase, what if these pages every rank for tons of of different key phrases?

In that case, why fear about site visitors from simply one key phrase? 

The truth is that we don’t have an actual cannibalization problem right here as a result of the existence of those two pages probably isn’t harming our web site’s general natural efficiency. If we had been to merge or delete one in every of them, we’d probably lose a few of our different key phrase rankings and see a internet drop in site visitors.

The trick to discovering actual cannibalization points is to search for pages that focus on the identical key phrases and fulfill the identical or very related intent.

The explanation for that is that if the intent is similar, every web page is unlikely to be rating for many completely different long-tail key phrase variations. So there’s often extra to realize than lose by consolidating the pages.

Let’s take a look at a number of methods to establish these pages.

Choice 1. Do a content material audit

Until your web site is large, cannibalization points must be comparatively simple to identify throughout a content material audit.

Choice 2. Have a look at historic rankings

This works finest once you wish to verify for cannibalization points for a selected key phrase

Right here’s methods to it in Ahrefs’ Web site Explorer:

1. Enter your area
2. Go to the Natural key phrases report
3. Filter for the key phrase you wish to examine
4. Click on the rating historical past dropdown

For instance, if we take a look at Moz’s historic rankings for “key phrase cannibalization,” we see three pages rating within the final six months—none of which ranked larger than place #8:

Let’s take a better take a look at two of these URLs:

/weblog/identify-and-tackle-keyword-cannibalisation-in-2019

/weblog/how-to-solve-keyword-cannibalization

Right here’s what they inform us concerning the pages: 

1. They’re each weblog posts. 
2. They’re each about the identical factor (i.e., tackling/fixing key phrase cannibalization).
3. The primary one is outdated (it has “2019” within the URL).

So this is sort of actually a cannibalization problem. The pages fulfill the identical intent and compete towards one another. Moz’s general natural efficiency may probably be improved by consolidating them.

Choice 3. Run a web site: search

Head to Google and seek for web site:yourwebsite.com "matter". You’ll see all of the pages in your web site associated to that matter. 

If we do that for web site:moz.com "key phrase cannibalization", you’ll be able to see that the primary three outcomes are those we beforehand found in Web site Explorer:

Choice 4. Run a Google search and take away host clustering

Operating a web site: search may also help you to search out potential cannibalization points. The one problem is that the outcomes lack a way of place, making it exhausting to know methods to deal with the problem. 

In case you take a look at the earlier instance, you’ll see that it most likely is sensible for Moz to merge three of their pages. However how precisely ought to they merge them? Which pages must be redirected, and which ought to they preserve? Is that this even probably to enhance issues?

You’ll be able to usually discover solutions to those questions by working an everyday Google search and eradicating host clustering—which is the place Google excludes related pages from the identical host from the search outcomes. 

For instance, if we seek for “key phrase cannibalization” in Google, we solely see one outcome from Moz within the prime 20:

But when we append &filter=0 to the Google search URL, it removes host clustering and divulges three outcomes from Moz within the prime 20:

That is helpful as a result of it offers every URL a way of place.

On this instance, we see Moz’s 2019 publish rating in place #6 and the opposite two posts rating in positions #12 and #13, respectively. 

So we all know now Moz may rank larger than place #6 by combining a few of these pages and redirecting. It’s additionally evident that Google at the moment considers the web page in place #6 probably the most related outcome for this key phrase. Thus, it most likely is sensible to work primarily with that web page and redirect the opposite pages there.

Choice 5. Test for a number of rating URLs

If Google ranks a number of URLs for a key phrase, that may be an indication of a cannibalization problem.

Right here’s methods to discover these key phrases in Web site Explorer:

1. Enter your area
2. Go to the Natural key phrases report
3. Toggle “A number of URLs solely” 

You’ll be able to see that after we do that for Moz, Web site Explorer finds the identical problem for the time period “key phrase cannibalization” as we discovered earlier utilizing methodology #2.

Simply bear in mind that this doesn’t at all times work, as Google tends to not rank a number of pages (in “common” positions) from the identical host, as mentioned beforehand. However because it’s tremendous fast to do in Web site Explorer, it’s nonetheless price a fast verify.

In case you’re assured that you’ve got a cannibalization problem in your arms, you’ll be able to usually enhance natural efficiency by consolidating the pages. That will imply redirecting an outdated, outdated web page to one thing extra related that you have already got or combining a number of pages into one thing new.

Both possibility will often have a constructive impression as a result of they consolidate recognized rating indicators like backlinks and inner hyperlinks into one web page slightly than diluting them throughout a number of pages.

We noticed success by doing this in 2018 for 2 guides about damaged hyperlink constructing.

Right here’s what we did:

1. We wrote a brand new information consolidating the information from each guides.
2. We printed the brand new information at one of many present URLs. 
3. We deleted the outdated information and redirected it to the brand new information.

You’ll be able to most likely inform after we did this within the graph beneath, which reveals our historic rankings for “damaged hyperlink constructing”:

Our historic estimated natural site visitors to those two pages additionally reveals the constructive change (the arrow marks the consolidation date):

Till the redirect in 2018, each pages had been getting a little bit of site visitors. After consolidating and redirecting, just one will get site visitors… however it will get far more site visitors than each pages (mixed) did beforehand.

TIP

Do not forget that it’s at all times a finest observe to swap out any inner hyperlinks after implementing redirects. You need to use the Hyperlink explorer instrument in Ahrefs’ Web site Audit to do this:

1. Crawl your web site with Web site Audit
2. Go to the Hyperlink Explorer instrument
3. Click on Superior filter
4. Click on +Rule
5. Change the brand new rule from “Is supply inner” to “Goal URL”
6. Enter the outdated redirected URL

You’ll then see an inventory of pages internally linking to this URL, together with the anchor textual content of the hyperlink and different particulars.

Is the answer actually this straightforward?

More often than not, sure. However as our extra skilled readers will know, there’s a number of “it relies upon” in search engine marketing, so there are occasions when issues are a bit extra nuanced.

For instance, now we have two very related guides:

Easy methods to Submit Your Web site to Search Engines

Easy methods to Submit Your Web site to Google

Each of those pages fulfill very related intent, regardless of focusing on barely completely different key phrases. And if we take a look at their estimated natural site visitors, we see that one web page’s site visitors pales compared to the different:

So this appears to be like like a cannibalization problem, and we should always most likely merge the pages. Proper?

Maybe. However then once more, our information to submitting web sites to search engines like google couldn’t be performing any higher in natural search proper now. 

It ranks #1 for its major goal key phrase…

… and appears to have just about maxed out its “site visitors potential” (it’s getting extra site visitors than each different related information):

So is that this actually a cannibalization problem? Is there actually something to be gained by merging these pages? Most likely not. And consolidating the posts into one would most likely trigger us to lose the small quantity of natural site visitors that the opposite information at the moment will get. So why trouble?

One other instance of a nuanced state of affairs is focusing on the identical key phrase on a number of pages that fulfill completely different intents. That is effective if the key phrase has blended intent, and this often isn’t an actual cannibalization problem. Certain, you may even see some key phrase overlap or periodic rank swaps. However every web page will often get site visitors from its personal bucket of long-tail key phrases.

(Once more, for this reason it doesn’t often make a lot sense to give attention to “fixing” cannibalization on the key phrase degree. You danger dropping site visitors from long-tails.)

However what in case your analytics inform you that one in every of these pages has little or no worth? 

For instance, maybe one is a brilliant ToFu weblog publish, and the opposite is a BoFu touchdown web page. 

On this case, so long as you’re 100% sure that the low-value weblog publish has no worth to your corporation, you’ll be able to delete the web page and redirect it to the touchdown web page to consolidate “authority.”

This can probably trigger you to lose some natural site visitors general. But it surely shouldn’t matter, as you recognized that site visitors as having no worth to your corporation.

Individuals usually attempt to clear up cannibalization on the key phrase degree with seemingly logical options which might be basically flawed in observe. Let’s take a better take a look at these, so you recognize what to not do. 

Delete the web page

That is hardly ever a very good resolution except the web page has no worth for your corporation (mentioned beforehand) or ranks for less than the “cannibalizing” key phrase. Each of those situations are fairly unlikely, so this can be a uncommon factor to do within the face of cannibalization.

Noindex the web page

Noindexing causes search engines like google to drop the web page from their index, that means it received’t rank for something. It is a horrible option to repair cannibalization and, once more, highlights the rationale why tackling cannibalization on the key phrase degree is sort of at all times a foul concept.

Canonicalize the web page

That is solely a viable resolution when coping with a number of pages which might be close to or actual duplicates, in any other case referred to as duplicate content material. Canonicalization is just not a option to repair key phrase cannibalization.

De-optimize the web page

This one sort of is sensible in principle however is basically flawed as a result of you’ll be able to’t de-optimize a web page for only one key phrase. Issues don’t work that method. For instance, eradicating all inner hyperlinks with the cannibalizing key phrase because the anchor is more likely to have an effect on the web page’s rankings for different key phrases too. The identical is true for eradicating mentions of the cannibalizing key phrase from the web page.

Ultimate ideas

Key phrase cannibalization isn’t actually a factor—no less than not in the way in which most individuals perceive it. Google doesn’t get “confused” by a number of pages about related issues or pages focusing on the identical key phrases. It is aware of what’s on these pages and ranks them accordingly.

Does that imply Google will at all times rank the web page you need it to rank? After all not. However that doesn’t imply that it’s “rating the mistaken web page” or that drastic motion is required to “repair” the issue. Many widespread “options” to key phrase cannibalization do extra hurt than good.
