When it comes to making money from a blog, adsense is one of the best blog monetization programs available. But it is very difficult to getting approved. I have been asked so many times by other bloggers, why google adsense is not approving their sites. Google is getting strict day by day. They don't approve any blog easily even if its six month or one year old. If you make site perfect to apply for adsense. There are less chances they will approve the site.
If the adsense account is showing blank ads on your website. Then you need to check out the following suggestions to solve these problem.
During the approval process for adsense for content ads, your ad unit will be blank until you have completed the second review step. Please note that it is necessary to place the ad code to be reviewed. Otherwise the review process will not continue.
The ad code needs to be placed on a page that receives regular visitors and that has content so please do not place the ad code on an empty test page that does not get traffic once you have implemented the code, you can check the ad unit in two ways.
If you have placed the ad unit near or within the content of your page the other content will shift to make room for the ad unit in the ad unit size that you selected.
If these methods do not show you your ad units please check again if you have implemented the ad code exactly the way it is presented in your account.
All new adsense for content publishers must complete a two step application approval process. This approval process only applies to adsense for content applicants. If you are monetizing with a different product you won't be subject to this two step approval process.
Step 1. Adsense conduct preliminary checks on your site and your details.
