The monthly volume of searches entered on keywords can be found with a few different methods. If you have a Google AdWords account, you can use Keyword Planner for this step. If you don’t, there are a few free sites out there that will give you similar numbers. Obviously, if a keyword has higher monthly searches you’ll want to keep it in mind. However, that also might mean that it has a higher keyword difficulty, and fiercer competition.
Now, it is not that these sites are not interested in Google users. In fact, they have hired us to help them increase their share. However, they are getting so much traffic from sites like Facebook that it seems there is less urgency about attracting this traffic and less willingness to change the site to meet organic standards. Not long ago, sites would urgently and unquestioningly abide by Google’s standards to court that traffic.
