Imagine your article is rated by your word selection when the ads are generated. Those in the title and any hyperlinks you have (try for a few links per article – even linking to other articles) are worth double. You want to have a mind to word selection in your articles as it will govern the types and the quality of ads showing on your page. The better your ads, the more chance people will click on them. The more people click on them, the more $ you make! Simple!
On a similar note, be sure to click on an ad or two when you enter the site. People are excited over BOA’s spare change program. This is similar. Every penny counts. Especially since it is someone else’s pennies that they are giving you!
