In addition to this blog, I have another one over at my Best Online High Schools website. I added the blog and the forum to that website a few months after it got going in order to increase traffic.
Let me assure you of one thing: When I have more traffic on that site, I sell more copies of my book. When I have less traffic on that site, I sell less copies of my book. This teaches me that driving traffic is a good thing because I make more money that way.
Here's my question, though. Should a blogger select topics specifically because they want to drive traffic in their direction and they know certain terms will work better in Google?
My answer is absolutely. However, the posts have to be of interest to your readers. It has to be information that they want to read.
For example, I have been blogging over there about free online high schools. I know over the next several weeks there will be many posts related to that topic. I know that the Google gods will appreciate the effort and reward me.
Here's the catch: The most common question that I get asked is about whether there are free online high schools. I know that my readers are very interested in that topic. That is what makes the choice acceptable.
There are people who use all sorts of pornographic terms, some you can see and some you cannot see (but which are there nonetheless), in order to get Google traffic. I think that is wrong for any number of reasons, not the least of which is that you should be able to trust that what you are searching for is what you will find.
