Not once has there been even the slightest impact on any of my Google rankings. Not even once.
To clarify,in my previous post i was refering to competitive searches (results 10-20 million) for example. If results are 200,000 and you cant make top ten, something else is wrong.
There's a chance that something other than layout,content or seo tweaks could be affecting it. I've maintained dozens of sites over the last few years and saw many positive, and sometimes negative serp fluctuations as a result of code and content changes, link gathering etc., but a couple of the sites seem to be dead in the water too. I am almost sure its server stuff but havn't taken time to study it. Just in case , you might check who else is hosted on that server, check dns settings, etc.
