Indexable and non-indexable pages

For every page that you're monitoring ContentKing checks whether it's indexable or not. The indexability status of a page is displayed, and for non-indexable pages also the reason(s) for being non-indexable are displayed.

How ContentKing determines indexability

For a page to be indexable the following criteria have to be met:

  • Indexing must not be disallowed by the meta robots directive
  • Indexing must not be disallowed by the X-Robots-Tag HTTP header directive
  • The URL can't be inaccessible to robots through a Disallow-directive in the robots.txt file (opens in a new tab)
  • The page's canonical link must point to itself or be absent

The canonical URL needs to match exactly with the actual URL. Often we see a close mismatch between the canonical URL definition and the actual page URL. Common mistakes:

  • Not using the same protocol (HTTP and HTTPS)
  • Not on the same sub-domain ( and
  • Not having the same casing (URLs are case sensitive)
  • Not having a trailing slash in one of the two definitions

See our Academy article on Duplicate Content (opens in a new tab) to learn more about this.

Indexability and the impact on auditing

ContentKing understands that not all pages are meant to be indexable, and to prevent you from getting false positives when it comes to page auditing we automatically ignore the following auditing tests on non-indexable pages by default:

  • All issues in the Meta Information category
  • All issues in the Content Headings category
  • The Image missing title-attribute issue

You can easily override this by unignoring the tests for the Non-indexable segment.

Duplicate content tests

When testing for duplicate content, ContentKing takes the following criteria into account:

  • Only indexable pages can cause duplicate content issues
  • Paginated pages cannot cause duplicate content issues
