I completely understand the ads for Fat & Lovely Dating and U2 songs, scroll down a ways and you will see articles for fat acceptance and U2. I am puzzled about Pretty Mexican Wives though. My skills with SEO writing and keywords must be severely lacking as the advertisements rarely relate to the actual topics I am talking about. Most often the ads just defer to the writer Zane - a black woman who writes erotic romance novels. Laughingly the exact opposite of me.

All over the Internet you can read about bloggers making hefty cash with Adsense. I am not one of them. I actually only signed up to see how many people were coming by the Lloyd Zeffler Web log. One question I may have is - does having Adsense on your blog add to the legitimacy of the site? Or does it turn off readers?

I know that any site I click on where you have to read through 1 and 1/3 of screen ads before you get to the content is one that I typically leave without even bothering to scroll down. Maybe there are some ad wizards out there who can help me out.
