Google webmaster not crawling my website [[url removed, login to view]] at a constant rate. The problem exists since past 6 months. Though there are more than 3500+ url links in sitemap. But these days Google webmaster crawls only lesser than 1000 URL's.? I am unsure if some tables in the database is corrupted which restricting google to crawl is. I have tried all my might to fix the problem, removed all the plugins, all ad banners, yet I do not see much improvement.? I am a programmer and have good seo knowledge, but I am unable to fix by myself. Hence request only expert's to bid on this.
