A new client of mine had a WordPress website that somehow ranked well on Google but had comments on every possible page with spam on every possible page...every page. Naturally they sank to the deep abyss of Google SERPS. I've been working on creating a new website for them and they've been up for a couple weeks now and there won't be any more spam ever. How long will it take for them to recover? Google was quick to spider the new site.
