A Brief History of SEO


When the first search engines existed SEO was very simple. Webmasters (site owners) would submit a site to a search engine which would then add it to it's database. The search engine would run a program (a web spider) which would then go and look at the site and look what keyword were present on the site.



A user would then search for a keyword and the search engine would return sites that contained that keyword. Usually the one that contained the keyword repeated the most times.



This worked ok but SEO companies quickly realised that it was open to abuse and they could get their client's sites up to the top of the search engine ranking just by stuffing the website full of keywords.



So what did the Search Engines do?


Most of the search engines, probably Google first, got smarter. They stopped trusting the website to tell them what it was about (although on-site content was still semi-trusted) but they switched to a model which determined the relevancy and 'trust' of a site by which sites linked to it. That is a very simplified version of what goes on but essential that's what happens.



SEO companies today have to try and get away from the old view of doing dodgy 'black hat' techniques to get a site up the rankings and switch to more legitimate means.

SEO Today


Today SEO has really become Search Engine Marketing (SEM) since its not about genuinely promoting a by creating useful content that people WANT to link to and making genuinely useful resources. It's no good just buying thousands of links back to your site; in fact Google employs penalties to sites that blatently do this and you will in fact see your rankings drop.



In summary SEO today is more about real marketing that trying to fiddle your way to the top of the search engines. If you want to be there you have to put the work in to build up trust in your brand and great content that people want to see.
