Based on this article I have a SERP that does infinite scrolling to load results greater than 10.   How do I go about implement rel=next & rel=prev for that? 
How do you implement Rel=next & rel=prev in infinite scroll for SEO?
seo;search engines;google search
The first page in the sequence should not have any rel next or rel prev, the second page should have:<link rel=next href=http://www.example.com/article?story=abc&page=2/>and<link rel=prev href=http://www.example.com/article?story=abc&page=1/>And so on through the sequence until it finishes. Since your page infinitely scrolls and these tags are designed to go into the <head> of the page I don't think it's possible to implement these tags in your case - as there is actually only a single page.
