I have come to believe that conducting small-scale SEO experiments can sometimes be more instructive than reading through massive case studies.
For instance, simply changing an anchor text pattern, adding a few links or making minor adjustments to a page structure makes it much easier to pinpoint the cause of any ranking fluctuations.
The problem with changing ten things at once is that, even if rankings improve, you cannot determine which specific change actually drove the result.
Furthermore, since search engines are constantly evolving, an SEO technique that worked six months ago might yield different results today.
That is why I find it more effective to test just one variable at a time and keep a simple record of the results.
