Ok, I do the SEO for hottanningbeds.com. About 2 weeks ago, we were sitting pretty at #20 for our major keyword, 'tanning beds'. Then we just completely disappear from the SERPs. I ran a site:hottanningbeds.com command and we're still indexed. Now, I'm pretty sure the problem is that I was running w3c validation, and broke some obl's, but I got those fixed within a couple of days and the broken versions never showed up in Google's cache. Now we've been dropped from more SERPs for specific keywords and I have no idea what is going on. Any ideas?
