Recently, one of my client's websites went down due to web hosting maintenance issues. His website was down for a week. Before this happened, he was ranking on the 2nd page and nearly on 1st page for several major keywords in his industry within a month of me doing SEO for him. After his website was back up and fully completed (it was still in the design phase when it was ranking on 2nd page and not all pages were done). I submitted a sitemap of his latest finished website, but he is still not back on Google. He's ranking on the 8th page now for some of the keywords where he ranked on the 2nd page, and he hasn't been put back up on any high spots despite the fact that he has over 400+ backlinks with keyworded anchor texts. I am able to get every client ranked on the 1st page of Google for major keywords, yet this is the first time that I've had so much trouble getting Google to get this guy back up on prominent pages. Any suggestions?
