Once you're approved
How quickly will Google ads start appearing on my site?
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 (e.g. AdSense for search, mobile, video, games, etc.) you will not be subject to this two-step approval process.
The first step in the process is a preliminary check on your site and your account details. The second step in the application process requires that you implement the HTML ad code on your site. Once you've started generating ad impressions, temporary “blank ads” will be shown until the final approval process is completed. These blank ads will blend into the background of your pages and shouldn’t interfere with the user experience.
During this time you won’t be generating earnings and if you log into your account you’ll see a red alert banner stating your account is still under review. This review period also gives us the opportunity to crawl your site and add it to our index so we can start serving ads as soon as you’re fully approved.
For more information, please refer to the publisher application process post on the official AdSense blog.
After you’ve implemented the ad code and we’ve completed our review of your site, a final approval decision will be made. If approved, live ads will start showing in your existing ad units.

Your ad relevance should increase over time. However, keep in mind that if you make changes to a page, it may be 1 or 2 weeks before our crawler captures the changes and updates our index to provide more relevant ads.
Adding the AdSense for search code to your pages will instantly generate an AdSense for search box. As search results are displayed on Google-hosted pages, relevant ads will appear immediately, if ads are available for the particular query.
