ARTICLE AD BOX

Google’s John Mueller answered a question connected LinkedIn astir however Google chooses canonicals, offering proposal astir what SEOs and publishers tin bash to promote Google however to prime the close URL.

What Is A Canonical URL?

In the concern wherever aggregate URLs (the addresses for aggregate web pages) person the aforesaid content, Google volition take 1 URL that volition beryllium typical for each of the pages. The chosen leafage is referred to arsenic the canonical URL.

Google Search Central has published documentation that explains however SEOs and publishes tin pass their penchant of which URL to use. None of these methods unit Google to take the preferred URL, they chiefly service arsenic a beardown hint.

There are 3 ways to bespeak the canonical URL:

Redirecting duplicate pages to the preferred URL (a beardown signal)
Use the rel=canonical nexus property to specify the preferred URL (a beardown signal)
List the preferred URL successful the sitemap (a anemic signal)

Some of Google’s canonicalization documentation incorrectly refers to the rel=canonical arsenic a nexus element. The nexus tag, <link>, is the element. The rel=canonical is an property of the nexus element. Google besides calls rel=canonical an annotation, which mightiness beryllium an interior mode Google refers to it but it’s not the due mode to notation to rel=canonical (it’s an HTML property of the nexus element).

There are 2 important things you request to cognize astir HTML elements and attributes:

HTML elements are the gathering blocks for creating a web page.
An HTML property is thing that adds much accusation astir that gathering artifact (the HTML element).

The Mozilla Developer Network HTML documentation (an authoritative root for HTML specifications) notes that “link” is an HTML element and that “rel=” is an attribute of the nexus element.

Person Read The Manual But Still Has Questions

The idiosyncratic speechmaking Google’s documentation which lists the supra 3 ways to specify a canonical inactive had questions truthful helium asked it connected LinkedIn.

He referred to the documentation arsenic “doc” successful his question:

“The mentioned doc suggests respective ways to specify a canonical URL.

1. Adding tag successful <head> conception of the page, and another, 2. Through sitemap, etc.

So, if we see lone constituent 2 of the above.

Which means the sitemap—Technically it contains each the canonical links of a website.

Then wherefore successful immoderate cases, a mates of the URLs successful the sitemap throws: “Duplicate without user-selected canonical.” ?”

As I pointed retired above, Google’s documentation says that the sitemap is simply a anemic signal.

Google Uses More Signals For Canonicalization

John Mueller’s reply reveals that Google uses much factors oregon signals than what is officially documented.

He explained:

“If Google’s systems tin archer that pages are akin capable that 1 of them could beryllium focused on, past we usage the factors listed successful that papers (and more) to effort to find which 1 to absorption on.”

Internal Linking Is A Canonical Factor

Mueller adjacent explained that interior links tin beryllium utilized to springiness Google a beardown awesome of which URL is the preferred one.

This is however Mueller answered:

“If you person a beardown preference, it’s champion to marque that penchant precise obvious, by making definite everything connected your tract expresses that penchant – including the link-rel-canonical successful the head, sitemaps, interior links, etc. “

He past followed up with:

“When it comes to search, which 1 of the pages Google’s systems absorption connected doesn’t substance truthful much, they’d each beryllium shown likewise successful search. The nonstop URL shown is mostly conscionable a substance for the idiosyncratic (who mightiness spot it) and for the site-owner (who mightiness privation to show & way that URL).”

Takeaways

In my acquisition it’s not uncommon that a ample website contains aged interior links that constituent to the incorrect URL. Sometimes it’s not aged interior links that are the cause, it’s 301 redirects from an aged leafage to different URL that is not the preferred canonical. That tin besides pb to Google choosing a URL that is not preferred by the publisher.

If Google is choosing the incorrect URL past it whitethorn beryllium utile to crawl the full tract (like with Screaming Frog) and past look astatine the interior linking patterns arsenic good arsenic redirects due to the fact that it whitethorn precise good beryllium that forgotten interior links hidden heavy wrong the website oregon chained redirects to the incorrect URL are causing Google to take the incorrect URL.

Google’s documentation besides notes that outer links to the incorrect leafage could power which leafage Google chooses arsenic the canonical, truthful that’s 1 much happening that needs to beryllium checked for debugging wherefore the incorrect URL is being ranked.

The important takeaway present is that if the modular ways of specifying the canonical are not moving past it’s imaginable that determination is an outer links, oregon unintentional interior linking, oregon a forgotten redirect that is causing Google to take the incorrect URL. Or, arsenic John Mueller suggested, expanding the magnitude of interior links to the preferred URL whitethorn assistance Google to take the preferred URL.
