Competition is the hardest part of the equation to deal with. If you have it, you have to work very hard to rank well in a search engines, if you don’t have it, the seo work is very easy.
A simple way to check for your online competition is to place quotes around it and search for it in Google. For example when you search for – “Broward roofer” the results on the right say there are only five other sites in Google that have that exact phrase. So the competition is low. This would be an easy site to get to the first page of Google, (waterproofroofer.com is my work). If you search for “Police Stuff“ you will see that there are 21,000 other sites in Google with that phrase. That phrase would be much harder to optimize for, (Policesites.info is my site).
Finding a phrase that people are searching for, using a keyword tool combined with using the term in Google with quotes will help you find a good keyword.
