I've got a blog that is 6 weeks old with 10 posts on it. 4 of the posts were ranking on the first page of google. The other ones were on page 2-5. All of a sudden they are all gone today ranking somewhere between page 15-25. All of the pages have great on page seo, but I was building links quickly. I'm convinced I'm in the sandbox, and I'm trying to figure out first of all how long it takes to get out, and second what should I do in the meantime? Should I keep posting and building links, or just give it up?
