I have a blog with around a 100 indexed pages, with a number of pages ranking on the first page for relatively competitive keywords. All unique content and backlinks from a range of different sources including authority sites such as Wikipedia etc. (do follow and nofollow), but for some reason Google is being stubborn about indexing new posts and content (seriously taking there time). Bing are having no such quibbles and indexing new posts quite quickly (for Bing). Anyone have any insights?
