Ads run for a minimum of 30 days on my blog. The product/blog/service you're advertising must be family-friendly - if you know my blog, we'll say it must be PG-13ish. Or no deal.
Most ads you'll see will be 150x150 but I'm happy to work with any ad sizes you may have.
I reserve all rights in determining which ads run on my blog, and the current going rates for the ad space. Current advertisers are given first dibs on the same ad size and placement for the up-coming month.
For current rates, please e-mail me.
