How long does it taken until AdSense ads are displayed on your blog

This article has details about the time-delays between Adsense ads being added to your Blogger site (in header, footer, sidebar, or inside your posts), and the ads being visible to your readers.

Ten minutes ...

After you have signed up for AdSense and started putting ads onto your blog, you may find that you want to get the ad-code from AdSense instead of using the gadgets included in Blogger.

When you get advertisement-code from AdSense (eg to make an image-only ad) or because you want to put an ad right inside a post), there is a message saying that it will take at least 10 minutes until the ad display's properly.  Personally, I've found that it can take 20+ minutes Google is having a bad-hair-day.

So go and have a coffee, then come back and test that you've got it right after that.

Or 2 days!

The specific ads show are based on the page content.   Google's web-crawler needs to visit the page and index it before they can choose ads for your page.  And it can take up to 48 hours for this to happen.

So depending on the settings you used for what do do when no ads are available, readers may see a public-service ad, or may see nothing at all, for up to 48 hours after your ad is created.
