Hey guys, I got a client that had a website in Top 10, but this week the website dropped to 7th page and lost all the other significant keywords. I examined the link profile, but it is clean as a newborn baby - only quality relevant links and URL as an anchor mainly. Moreover, the on-page content is pretty rich and relevant. What would you say could cause this? Im gonna check GWT as soon as I get access, but I'm just wandering. The XML sitemap was created manually for this website, so maybe it was outdated a bit. Other than that they overused the meta keyword tag, but I wouldn't say it was a cause for such a drop. Any guesses from other SEOs?
