I disagree on removing adsense but not a fan of putting adsense units all over. Most of my blog posts have 0 adsense units but I do not mind putting a 300*250 or 250*250 unit in the top right corner of a blog post. I have changed the colors well to match it with my overall blog theme and I actually received few compliments from my readers about the way I have used adsense in my site.
One thing we have to keep in mind is there is no way that we can trick a reader now a days like in the early 2000's.
May be because of the lack of exposure I am only earning around $175 - $200 a month from adsense.
My other main income sources are,
CJ - Average $700- $900 a month
Retail fx in house partner's program - Average $500-$750 a month
Private ad sales- Only one 300*250 ad box for $125
I am considering to add one of my own product for sale in the near future.
Stay away from pepperjam , click booth and adbrite. ( My personal opinion due to various reasons.)
Have tried click bank and Never blue ads with not much success. ( You can try your luck.)
