We released new plugin Google Pagination Links (SEO)

If you break a single piece of content into multiple pages, you can help Google understand the ordering of those pages, and the fact that they are all parts of one longer article.

Plugin adds rel="next" and rel="prev" links in headers to indicate the relationship between component URLs. This markup provides a strong hint to Google that you would like us to treat these pages as a logical sequence, thus consolidating their linking properties and usually sending searchers to the first page.

Note.
Not registered version is fully operational and has only one limitation – trial period 15 days.

Compatible for NopCommerce 4.10, 4.00.
