I have two pages on a WordPress site with almost identical content, but one has relevant adsense ads and the other does not (just shows ads related to WordPress).
The two pages are: site.com/ and site.com/hompage-name
These two links point to the same page, they are just referenced in two ways.
The differences in the markup of each of these two pages is very minimal. One is drawn in index.php (the one with irrelevant ads) and the other in single.php (it has relevant ads).
There are also a few minor differences in the head section of each of these templates:
In the one that's showing relevant ads, the following four lines appear (they don't appear in the irrelevant ads page which is drawn with the index.php template:
<link rel="alternate" type="application/rss+xml" title="My Site Feed" href="http://mysite.org/pagename/feed/" />
<script type='text/javascript' src='http://mysite.org/wp-includes/js/comment-reply.js?ver=20090102'></script>
Any ideas why one page lists relevant ads while the other does not?
