SEO as a concept started taking shape in the nineties. It was then that website owners started realizing the importance of having their websites optimized for search engines. 1996 saw the first emails sent out by any SEO firm detailing the SEO services offered by them. Within a year or so SEO firms started gaining public attention.
The widespread appeal of SEO firms could also be attributed to the roaring success of search engines, especially Google. You can visit www.approachseo.com/ for the best SEO services.

A typical SEO agency in the early days would base its search optimization on file names, titles and Meta tags. But as the number of searches being made increased dramatically these factors gave way to other more important factors such as ensuring that the structure of a website was correct and also the number of relevant backlinks.
Google developed the feature of Page Rank; this was a number between 1 and 10 and the higher the number given to a website by Google the higher its importance in the eyes of Google.
Some SEO companies were quick to exploit this concept and manipulate their optimization accordingly. All they needed were some great links placed on high page rank sites to the website which they were trying to optimize and that site would rise dramatically in the search engine rankings.
