In the olden days of the early to mid 2000s the world of search engines was a kinder simpler one. You had a few simple search engines competing against the growing tidal wave of Google that was well on its way to sweeping up the entire Internet ocean in its wake. SEO tactics, then still in their infancy were equally rudimentary. You had link-farms and carousels, keyword stuffing and other questionable tactics just waiting for a name. That the so-called 'black-hat' SEO is as old as the business is no novelty but what is interesting is just how stark the contrast between 'white hat' acceptable and 'black hat' bad has become lately.
This article explains a few basic facts such as what blogs are, what SEO is, and how it affects your ranking with search engines.
