It’s much easier to remember you were on "Page 8" than to find your spot in an endless scroll.
Search engines prefer canonical URLs. If Page 8 of 49 exists as a standalone HTML page with that string in the body, but without proper rel="prev" and rel="next" tags, Google may treat Page 8 as an orphaned document. This dilutes the authority of the entire series. -- Page 8 of 49 -- HiWEBxSERIES.com
