Hi, Usually, a CTR under 1% is considered bad. A CTR of 1-2% is fair to middling A CTR greater than 2% is what you are looking for. A CTR greater than 4% is great. If you have a site that generates over 1,000 views/day, but you have a low CTR here some useful tips: Check up whether Google system can crawl your page through their webmaster tools. Try Google optimization guidelines to optimize your pages. Testing new ad formats, placements, or colors. For instance, in my homepage I've put one block ad (336x280), background: FFFFFF, border: FFFFFF, Title: 0000CC, URL: 008000. There are so many factors that there’s no way to predict a good CTR. I'd like to hear your tips to improve my low CTR. Nicola Deiana The3dtechnologies.com
