Just a quick question really, I've been using DIV tags, no tables etc., - perfect XHTML tags and my site isn't spidered v well as I thought it would.

Is it because my source code is maybe too advance for the Search Engines and Spiders?

Also by using things such as:
<META content="index, all" name="Robots"/>
<META http-equiv="imagetoolbar" content="false"/>

Is it effecting me?
