When considering a niche for a new website, based on SEO factors, one of the first things to consider is the number of monthly searches you hope to be able to drive to your site. The first step I would suggest is to find the 50 keywords you feel are most relevant to your niche and insert them into a spreadsheet.
In order to find these top 50 keyphrase opportunities I suggest you use Google’s Free Keyword Tool and base your search on the average number of monthly searches each phrase has been receiving. The next thing you want to figure out is the relevance of your niche topic in relation to each of these keywords. Relevance here refers to the possibility that two distinct niches could be competing for the same keyphrase.
For example, if I was considering starting a new website about training guard and attack dogs, one of the keyphrases I might select would be “protection training”. The problem is that when I search for this term on Google, I receive search results for both “executive protection training” as well as “K9 protection training”
