Hey I am selling advertising spots on http://www.mactricksandtips.com Stats: >100,000 Pageviews >80,000 Unique Visitors Page Rank 4 Alexa ~150,000 ~2500 RSS Readers 4 Spots Adverts are located in the sidebar above the fold. Most Traffic is from Google and Direct visitors. There are 4 spots in total. Each spot is $40 so it works out to about $0.4 CPM. Each advert can be gif, png, jpeg etc and is 125px x 125px. The cost runs for 1 month starting from when ever you buy it. Each new advertiser gets a small review (and a link to your site) at the beginning of each month as part of a monthly roundup. If you want to purchase an advert go to http://buysellads.com/buy/detail/245/ they will take care of all of the payment processing (visa, paypal, amex, mastercard accepted) and will let you upload your advert onto my site automatically. It should then appear as soon as you submit payment. Any questions please ask.
