I currently have posts/page setting at 10. By default, it's 20 on XenForo. Clearly 20 posts/page improves the text/code ratio which is supposed to be an important SEO factor. I wish to know about first hand experiences of posts/page & SEO relation. Showing lower number of posts/pages improves the overall number of pageviews - and affects advertising revenues. What do experts here think about the ideal number of posts/pages.
