This article is intended to explain why there are fewer searchable pages found by the Siteimprove SEO tool than the total pages found by Siteimprove Quality Assurance. After scanning your website, our crawler builds up an index of the pages on your website, those can been seen in the Quality Assurance Summary.

In the SEO tool, Siteimprove checks how many of the total pages in QA are tagged for search engines as pages that should not be shown in their search results. Pages that have a “rel=canonical” tag or a “noindex” tag (in the HTML) will never be shown in a search engine's search result. These pages are called "non-searchable pages". Tagging pages with "rel=canonical" and "noindex" tags indicates to search engines it should not be indexed in the search results. Siteimprove does not perform any SEO checks of these pages until these tags are no longer present on the page.
A list of "non-searchable" pages can be found in the following way:
1. Select SEO from the Tool Selector
2. Select Pages from the Tool Menu.
3. Under the Searchability column in the Pages Dashboard, filter your results by selecting Not Searchable.
The total index of pages in Siteimprove minus the non-searchable pages are the pages that are left to be checked for SEO problems are called “searchable pages”. Depending on how many "rel=canonical" and "noindex" tags you have set on your pages, you will typically find fewer searchable pages in SEO than you see in your Quality Assurance tool.
