Generally speaking, Google Adsense is a very simple way to catch advertisers from all over the world. You have to submit your blog to search engine (Google) to approve it. Whenever a viewer clicks on a link the advertiser has to pay to Google some amount as a fee.
Some basic rules for using Google Adsense
1. What you need to do, you just have to follow the rules that are written in Adsense form. Keep your ads always above the main fold. Do not forget that the top click through rate is the first instance of the ad in HTML code.
2. Some people think of modifying the code but they perhaps, do not know that by doing so they are just creating problem therefore, do not rectify or modify the HTML code of Google Adsense.
3. Most of people believe in fishing, that means they ask their friends or visitors to click on their Google advertisement. Moreover they include some incentives for viewers to click on the ads.
It’s not a right way of marketing. It gives negative impression towards the product or site. That's why do stop fishing to viewers and make sure that Google ads should only be labeled with text – 1, sponsored links or 2, advertisements.
4, To achieve traffic on website some of owners click on their own ads, that’s not a right approach, they think that google will not catch their trick, but it is not so, google catches it.
5. Make sure that you never place ads in pop-up window or in an error page or even empty page and also take care of sheer wastage of money and time to buy costly adsense keywords lists. Generally, without background color and borders Google Ads always look well. Make sure that the border color and background color should be as similar as your page background color is.
