Hello there. I have a very targeted website, made for adsense, on the “cheap auto insurance†niche. I have 2 questions/issues: How can i make the adsense ads match the website topic? I have a list of websites (that are currently using adwords for marketing their business) that are a perfect match for my website topic. Can i some how select this list of url`s to advertise on my website? Sorry for my English. Thank you!
You should create content for each advertizer you see fit. create more pages and talk about them. You don't have to link to them, just talk about them by reading their homepage or the pages they're promoting on adwords. You'll see it'll catch interest from adsense and themselves. Then when you create an ad unit, and a custom channel, you can add a description, then it's up to you to sell your ad space to the potential advertizers, so use their niche vocabulary in your description!
The most common cause of AdSense ads unrelated to the sites topic is that your keyword density is too low. Think about what keywords people would search for when looking for the products you would like AdSense to promote and make sure those keywords occur at least once on each page.
