You know better your traffic. If your visitors come from search engines, they will be more likely to click on your banners, so you’ll get a higher CTR (click to rate). This situation is perfect for CPC (cost per click) campaigns and Google AdSense is well known for its good results. If your visitors come from various referrals or directly by tapping your blog address in the address bar, they won’t click or hardly click on these banners. What can you do? You still have some good options. In this situation, one or more CPM advertising networks will be great for you. Some of them pay really well, and don’t care about the CTR. All that really counts is your number of daily impressions, because what you’ll get is based on the CPMs.
