The search engine functions in the same way your library card functions to catalog books inside that labyrinthine store room of information.

Search engines, on the other hand, are mostly administered by web robots or crawlers who sift through the word content of each and every webpage published on line.
There are three distinct search engine optimization techniques: the white hat, the gray hat, and the black hat. As their colors suggest, they’re the good and evil of search engine optimization.

SEO is also about making the directory more systematic, and black hat SEO, because the techniques are very wily, tend to go against that very principle.
