Many people often wonder why all credible Search Engine Optimisation companies charge on going fees, I mean what else is there to do once the sites position has been achieved for its keyphrases?

The answer of course is that it takes a lot of effort to get a site listed for a competitive key phrase and just as much effort keeping it there.  Not many non optimisers are aware that Google continually changes its algorithms and that it is continually revaluating a sites relevancy and trustworthiness to appear for the phrase it has been optimised for.  In short a lot of work has to be done to keep a site listed for its key phrases. The thing most people don’t understand is that that most work that is done to keep a site listed in Google can not be seen within the site.  Without the skills of an optimisation company no site will keep it’s position for long if it just has a one off effort for optimisation and is why ongoing optimisation fees pay dividends in the long run.
