If home ad placement is good then what do u think after how many posts do i need to place ad. Before placing ad code in middle of the post i was using 8 posts at home. But now i have 6 posts per page. (but i want to show 8 posts per page)
test, test, and test will only answer your question, it varies from one blog to another however above fold, center, and sidebars are generally considered well performed
