Website completely dropped off Google in our top keywords

[eriksimpson]

Over the weekend, our website (http://www.esdandassociates.com) completely dropped off the google database in our top keywords. The only way that our site can be found is if you specifically type in the company name. Other search engines were unaffected and rankings remained the same or rose for the week.

Previous keywords that we ranked in the first couple of positions (san antonio advertising agency, san antonio public relations) are now not in the top 50.

We have not made any recent changes to our site besides basic content updates and all appears normal regarding crawler access. I have also not been able to find anything irregular in webmaster tools.

Any ideas?

A similar thing happened to our sites a few months which was blamed on panda - our site shot completely down the rankings, but then came back a couple of weeks later in a better position.. only for it to then drop again!

Have you added any new links or lost any good links recently or has your site gone down recently for any period of time? If G can't access your site when it tries to crawl or has slow load times it may be a contributor.
