how should pagination be optimized for seo? the default pagination for a blog is to start at 2 and then count up: myblog/ myblog/2 myblog/3 myblog/4 myblog/5 but publishing a new post moves all the existing posts down one step. therefore paginated urls will have their contents completely changed after a few days. google is obviously taking the challenge and re-indexing/updating these urls regularly. but can a location that has completely different content on every crawling attempt be trusted? what's the seo solution for this? follow,noindex on paginated pages? or create perma-paginating by month instead of counting?
