Remember also that the ads are served from information gathered in a crawl of the site.
Therefore, a single post will be more focused since every time the crawler comes the post is the same.
However, on a front page, the post changes.
So, your front page is a perfect example of this. You have 3 posts, the oldest post on this page is on diets, the crawler came through and picked up the data and served relevant ads. Since that crawling, you have written 2 more posts on other topics, but the ads are still on diets.
The last time your site was indexed was May 5th, and the top post that day was the 3rd post on your front page.
The trick is to get the site indexing faster. |
