Search Engine Optimisation (SEO) is something of a Holy Grail in web terms. It is the skill (some say art) of ensuring maximum visibility of websites for search engines, whilst maintaining the site as a working entity in its own right.
The process involves identifying search keyphrases and editing the site code to maximise these phrases. As search engines do not give out their forumla for ranking websites, much is left to best practice (or best guess even).
I have taken SEO on a stage further and created models which integrate with the results themselves to not only produce good search terms, but create a reporting tool which scores each position for effectiveness.
"You've lost me!"
Ok. Using tools out there, we know how much potential traffic a key phrase can get. Being in the top 10 in Google for a phrase which no-one ever searches for is no good, whereas a top 20 position for a popular search terms is much better and will result in more traffic (which at the end of the day is the whole point of this).
Each keyword or phrase is given a score of importance, which married with the search ranking gives an overall coefficient (CPR). Using this formula, we are able to see a true picture of the effectiveness of SEO in relation to potential site visits, rather than a seemingly impressive-looking list of high ranks on keywords which attract little or no traffic.
