I had a recent comment from a reader that asked this question. "Why do you have so many ads on your website?" This is a simple answer. The ads are there because I make money from them. I can't argue with free money. Everyone should be doing it. Everyone that is not doing it is missing out. The best part about placing ads on your site is it's absolutely free to sign up. With most companies you have 100% control of what ads will appear on your site. With google it's a little more complicated, Google has control, but you can either filter the ads you don't want, or enter in the keywords that you want your ads to target to (the most effective).
If you have any questions about advertising or anything else, just send me an email or post a response.
