Hi I am quite happy with the look of my blog, I do have a text ad unit on the right sidebar, but I feel I need another ad unit, any suggestions on where it should be placed? Thanks John http://jgblogging.com
I was going to say the same advice. However, you can add sub menu using link units and a large rectangle before the comment section. All the best.
Too much ads on your blog will looks messy. If you use more ads, it is also possible that the ads showing on your page is the low-paying-ads.
