Writing quality content is very vital as it ensures that visitors have something fruitful in your website. You should always remember that without real visitors and targeted traffic you can never get Advertisement clicks. So make a habit of writing quality content and presenting it well in your website or blog.
2. Website Design is Vital.
In order to get good amount of CTR for your ads it is important that you have a neat and clean web design with advertisement spaces at strategic locations. You can always hire a web designer to do the work or code on your own from scratch. Our HTML getting started guide will help you to learn HTML faster. If you are using Wordpress the I highly recommend that you invest some money in buying premium themes. My recommendations will be to go for WOO Themes or Studio Press. Their themes come with Advertisement spaces where you can simply copy paste your ad code.
3. Vital Ad zones.
According to massive surveys it is found that Large Rectangle, Vertical Banners and Inline Rectangle works the best. I am not forcing you to keep these ad formats but there is nothing wrong going with the mass success. Below is a graphical representation of Adsense Hotspots Zones showing ads in which areas are clicked the most.
This is something which I am personally not fond of but certainly works and can rocket shoot your CTR if you execute the plan correctly. The sole purpose for you should be to blend Advertisements with your content in such a way that users automatically click those ads thinking it's a part of your website, or are easily bought to the attention of visitors as they scan through your content. See this website here. If you scroll down on the right hand side you can see how well the text ads are blended with the entire website theme. This tactic increases your CTR for sure.
5. Do not lose hope and focus on your Website.
According to a survey by Google the website in the first page of particular keyword get a CTR of about 5-6 percent. At an average 2 percent is considered quite good. I should also mention that higher CTR does not guarantee higher income. A blog or website with a CTR of say 2 percent can earn more with a blog of CTR 7 percent even with the same traffic. A lot depends on your topic choice and Advertisement relevance. My suggestion to you is that do not put adsense ads until you get at least 100 unique visitors a day to your website. GOOD LUCK!
