My AdSense was approved weeks ago! Why no ads, on my blog, even now??The owners are certain that their blogs are mature and righteous - and that they received final approval for ad content.
Looking at the blog - when the blog name is provided - we see one unfortunate detail, in many blogs. Blogs published to dynamic templates.
Blogs which use dynamic templates will not show ads.
AdSense is a contextual ads hosting service. Ad content depends upon automated analysis of blog content.
AdSense crawls a wide range of blogs and websites, analysing access and content.
The AdSense ad content crawlers are designed to crawl, and analyse, blogs and websites of all brands and services. Normal crawlers, such as what AdSense uses, crawl a web site using the rendered page source.
Blogger and Google crawl blogs, using the Blogger generated sitemaps.
Blogger abuse classification crawlers, and Google search engine crawlers, use the Blogger blog sitemap. The recently added automatic Blogger sitemap should provide improved abuse and search indexing, for all Blogger blogs.
AdSense crawls rendered blog / website content - not sitemaps.
The AdSense crawlers, however, crawl rendered content - because part of AdSense crawling involves monitoring accessibility of blogs and websites, and what your readers see.
The bad news, that you'll be getting.
Insufficient content: To be approved for AdSense and show relevant ads on your site, your pages need to have enough text on them for our specialists to review and for our crawler to be able to determine what your pages are about.
If you want to use AdSense, you can't use a dynamic template - regardless whether Blogger cleverly packages AdSense gadgets in the dynamic template layout.
Yes, you will see more than this - and yes, you will (may) see ads - for a while. Not for long, though.
Blogs re published to dynamic templates will continue to show ads - for a while.
If you've had AdSense for years, and you just re published your blog to a dynamic template, you'll probably show ads - for a while. The AdSense crawlers, like the Blogger and Google crawlers, won't crawl every blog every day (maybe not every week or month).
AdSense will eventually crawl your blog, find no content, and your ads will stop.
No ads == no money for you.
