Hello andy, my website is madeup in PHP and supported of java script.

Might check to see if your site prohibits use of java scripts in the content blocks or sidebars, older Wordpress versions did this, they rendered Java null which made any script not get called.

Hello Vingesh,

This account is very old and is approx 2 years and shoing ad on differnt blogger but not showing on website.

Hello Andy thanks for suggestion but it has been more than 48 hours and is approx 5- 6 days but still don't showing but in blogger it's showing.

It's a combination of two issues, they are trying to use the same code on multiple sites which slows the process of Adsense determining which ads are best to serve and it reconciling that the ad block is on a new website that must be crawled. Either way once the delay is over the ads should show with no issues. This can happen even on 12 year old accounts like mine.

is that newly approved adsense account? If so, then it would take 24 to 48 hours to display new ads on your web page.

It can sometimes take up to 48 hours for a ad block to show on a new website as Google crawls the site content to see what it is about and match ads to it. Be patient.
