i plan to buy blog advertisement, been googled for a while.
if u ever buy blog ads, kindly share ur thought here.
why don’t you try adsense on your blog if it is mainstream related, i think you can get handsome earning through adsense 
You need to create an ad sense account first and than get ads through your account. You can place these ads on your blog and you can easily earn some bucks.
Yeah, I agree with you people. I’ve been using adsense with my blogs and it quite gives me an earning.
Yes agree with every one Google adsense is popular one to get advertising in your blog. I have a blog in Google sites. You can insert adsense anywhere & many adsense too in your blog. I like the Google sites blog & adsense so much.
What types of blog you are looking for to buy blog ads.You may visit different blogs in your niche and contact the blog publisher about your interest to buy blog ads.
adsense or yahoo ads are best advertisement and easy to manage them, you can get around 50% advertisement cost from advertiser if you use adsense
You need to go straight to those websites that are in your niche before purchasing. Buying advertising on any old site will definitely be a disappointment in the long run. You need to be targeting people that are directly interested in what you are selling.
For example, if I’m selling groceries, I’m not going to go put my banner up inside of a day care classroom. The vast majority of people who would see it would be young kids who likely don’t buy groceries in their household. However, placing the ad on the outside of the daycare might be beneficial because it would be parents who come and pick up their kids that would be much more inclined to see it. See how this works? Go to where the buyers are and advertise there.
