terms to optimise for. When comparing terms such as “funny stuff”, “funny clips” and “funny videos” it’s possible to see whichs ones are most searched for, and as importantly how popular or unpopular they are becoming.
To further refine a SEO strategy, why not browse through the first 10 or 20 results in google for these terms and try to ascertain the general quality and popularity of these sites. This can be done by checking the page rank, number of backlinks and alexa rating of the site in question. You can also use the google trends for websites to gauge site popularity. If one groups of results for a keyword phrase looks particulalrly weak that they may well be a good angle of attack.
