Multiple Pagination URLs
There are multiple rel=”next” and rel=”next” attributes on the page (when there shouldn’t be more than a single rel=”next” or rel=”next” attribute).
This may mean that they are ignored by the search engines.
How to Analyse in the SEO Spider
View URLs with this issue in the ‘Pagination’ tab and ‘Multiple Pagination URLs’ filter, and export all URLs using the ‘Export’ button.
Read our tutorial on ‘How To Audit rel=”next” and rel=”prev” Pagination Attributes’.
What Triggers This Issue
This issue is triggered when a page contains multiple rel=”next” and rel=”next” attributes.
For example:
https://www.screamingfrog.co.uk/
Has the tags:
<link rel="next" href="https://www.screamingfrog.co.uk/page2/">
<link rel="next" href="https://www.screamingfrog.co.uk/page3/">
How To Fix
Ensure there is only single rel=”next” or rel=”prev” attribute on a page and URLs are to canonical, indexable pages – so they can be crawled and indexed.
