Canonical Tag is Absolute

Our data allows you to check that canonical URLs are setup properly and help provide insights that could direct a digital strategy.


Simple Definition

HTML/Text pages with a self-referential canonical tag. This means a canonical URL that matches the URL crawled.


Values Returned

The possible values returned in this column are as follows:


The canonical URL is absolute


The canonical URL is relative

Missing Entry

The canonical tag is present but does not contain a canonical URL

Missing Canonical Tag

The canonical tag is missing


The canonical tag is incorrectly implemented


Canonical Tag is Absolute in More Detail:

Canonical stuff can have a huge effect on a site, using Raptor and the data our web crawler provides enables you to identify all canonical issues.

To cover some basics. This is what a canonical tag looks like, we have colour coded this to make it a little easier to understand.

<link rel="canonical" href=" "/>

Red = This is the HTML (the code) and encompasses the canonical tag

Grey = This is the ‘Canonical URL’ (variable), the part of the tag that you stipulate

The canonical URL needs to be both absolute (see example below) and consistent with the canonical URLs used across the site.

Red = The part of the URL required to be canonically consistent.

Grey = The various pages of the site… Subject to rules and best practice.


A bit more on Absolute Vs Relative URLs

The URL of a page is the only data / value returned so we thought it worth explaining in a little more detail. below is an example of a URL:

  • Internet Application Protocol (Protocol)
  • Sub-Domain
  • Top Level Domain (TLD)
  • Directory (Dir)
  • Sub-Directory (Sub)
  • Page or file / Resource


Examples of How This Data is Used

All the data our web scraper extracts is used in various ways by SEOs or web devs. We provide some examples of these uses below.


Example 1: Implementation Check

This most obvious use of this is to ensure that your canonical tags are not using relative links, but the other values returned in this column will help you to identify other problems as well.


Example 2: Missing Canonical Tags

A standard SEO check you can do with this data; is ensuring that every page that has a canonical tag, and that it is implemented correctly.
