1. Keep your blog on topic.If you are all over the map in regards to topics about which you talk about, advertisers won’t know if they are a good fit for your site.
2. Have an “Advertise with Us” Banner on your site
This is the single most important issue. It should click to an Advertising information page and have an easy way to contact you for more information and rates. Key points: Make it a graphical image or a tab. Keep it above the fold.
3. Show them the banners
If you currently have no paid placements on your site, put up house ads or partner ads in the same spot you would run a paid spot. (A house ad refers to banners for other products or sites that you or your company own)
4. User demographic information. Know your audience.The bare minimum is Male/Female % and average age of your readers. Other potentially useful information includes geographic, HHI, single/married, number of kids. etc. How do you get this info? You can do site polls, survey’s, or get more detailed stats from ComScore or Quantcast.com
5. Throw up a free bonus ad.
By putting a free advertisement on your site, you may not only encourage similar ads or competitors to that product, but the company you added for free may decide to advertise with you. Ask for full disclosure of the performance of the campaign in return. (Total clicks, total purchases etc. ) Key points. Put the free bonus up with a direct URL without tracking tags or affiliate tags.
6. Keep the ads on your site specific to your site
Don’t have smiley ads and wallpaper ads if your site is site is about mobile phones.
7. Have an ‘About Us’ section.
Clearly explain who you are and what your site is about. And also why you are an ‘authority’ on what you are writing about, and why anyone should care about what you have to say.
8. Show your site stats.
You need to show at least the basics for site statical information: Monthly unique visitors and total number of impressions are the 2 key ones. Other less important can be Google PR & Alexa rank.
9. Keep your blog professional.
If you are talking about your cat, (Matt Cutts), ranting about your drive to work, swearing or bashing every product you can think about, it will scare away advertisers.
10. Don’t use Google AdSense on your site.
OK, this could be the most painful one for most people especially if you are generating a few hundred bucks a month from it already. But Google ad sense devalues your site and makes it look unprofessional. You have to ask yourself, “Do I want some real revenue from my site or Google’s table scraps.” Darren Rowse
