I have this website in gaming niche which receives around 12k exact searches. Put up a wp site. Published related content, and one seo keyword targeted page which I set as the website's home page. Everything is going as planned and soon am around #15-20 for the main keyword. Then it happens, am dropped down to 300, okay nothing to be surprised of, i have had it happen numerous time. The weird thing is: Instead of my main page, google has started ranking the "about" page of my website. WTF? I have changed the permalinks heavily, this won't effect my work as all my backlinks are towards the domain. Publishing new content and resubmitting sitemap to google. Let's see how it goes.
