Hi! I have many MNS and all works good but I have some problem with one! When I create a new post (wordpress platform) google needs 3-4 days to index my new page. My websites have 30 post I use this Wordpress Plugin: XML Sitemap Generator To index my new post I ping my blog with some online ping services, I create 10/20 bookmarks in high Pr websites and I create 2/3 article in article marketing websites. This strategy works good with all my other websites but not in this. Why? What is your suggestions?
