When performing an audit on a site with pages that aren’t ranking, there are a number of basic steps that everyone can do to check whether your page has been filtered out by Google, or if it’s being indexed at all. Dr. Pete from SEOmoz sums up these checks in a great post entitled 10-minute missing page audit.
It’s entitled “10 minutes” not because that’s how much time you should spend checking ranking issues; it may take you less if you’re lucky and find it straight away, or the problem may require further time and deeper analysis. But it’s a great step-by-step checklist to anyone to follow.
