Pagination sequencing errors, also known as pagination glitches, refer to errors that can occur when the sequence of pages in a paginated series are not displayed in the intended order. This can lead to issues such as duplicate content and lost search engine indexing opportunities.
To avoid pagination sequencing errors, be sure to use rel=”next” and rel=”prev” links on your paginated pages so that search engines can correctly identify the correct order of pages (Google doesn’t use these as a ranking factor anymore though).
You may also want to use canonical URLs on your paginated pages to help ensure that only one version of each page is indexed by search engines.
