There is little value in focusing all of your attention on trying to analyze
something that is designed for the purpose of constant, continual and nearly
perpetual change. Don’t spend hundreds of hours trying to analyze algorithm.
Instead, use your time wisely to create fresh original content that is mildly
optimized for those low competition “niche phrases” that are being used by
searchers (the ones who know what they are looking for and know how to search.)
Excell at keyword research and it’ll make your optimization work MUCH easier.
