Internal Nofollow Inlinks Only
Pages that only have rel=”nofollow” links to them from other pages.
Links marked with nofollow link attributes will generally not be followed by search engines, so this can impact discovery and indexing of a page.
How to Analyse in the SEO Spider
View URLs with this issue in the ‘Links’ tab and ‘Internal Nofollow Inlinks Only’ filter, and export all URLs using the ‘Export’ button.
To populate this filter ‘Crawl Analysis’ must be performed via ‘Crawl Analysis > Start’.
Nofollow Inlinks can be seen in the lower ‘Inlinks’ tab with the ‘All Link Types’ filter set to ‘Hyperlinks’, where the ‘Follow’ column is ‘False’.
Export in bulk via ‘Bulk Export > Links > Internal Nofollow Inlinks Only’.
What Triggers This Issue
This issue is triggered when pages only have links marked with rel=”nofollow” pointing to them from other pages within the website.
For example if the following page:
https://www.screamingfrog.co.uk/meet-the-team/
Was linked to from only one page:
https://www.screamingfrog.co.uk/about/
Using the following link:
<a href="https://www.screamingfrog.co.uk/meet-the-team/" rel="nofollow" >Meet The Team</a>
How To Fix
Review the use of rel=”nofollow” on internal links to pages. These might be valid to URLs that ideally wouldn’t be crawled, or they could be by mistake.
Remove the nofollow link attribute to important URLs you wish to be crawled, indexed and receive PageRank.
