For many of us making money on the web is just a matter of trudging along and hoping that someone will hit the ad links on our sites. This can and many times does work BUT if you truly think about it, this means that the person did not find what they were looking on your site SO they saw a glimpse of what they needed on the ads. THIS is a very good piece of knowledge to have. It means that if there are key words to items, subjects or other areas of interest that are mentioned in your blog entries or on your web site and you do not have ALL the information it may be a good driving factor in moving people to a new site and the way they may get there is through one of your ADS.
My advice. Keep at it! write your blog posts, give the information you have and provide the most accurate information and people will come and if they don't find what they are looking for maybe they will through your site. Good Luck and Keep Making Money on the Web.
