Ok lets say my website is about dogs primarily... then I add a webpage about watches. When I upload the page and look at it. The whole page has nothing but ads about dogs. Is this because the spider hasnt come by yet? or because my whole site is about dogs, and despite the page being about watches, the ads will always be dogs.
Sometimes it does takes a bit of time for the ads to match. As long as you hjave good title/description H1 tags and text on that page you should come good.
I noticed exactly this same - sometimes I get sites completely not relevant. This is quite fun, because I still see sometimes ads from my first site, where I don't use ads anymore. Can't stop this.
ok you know whats weird... I host 2 domains on the same site. both point to the same pages.... now when i type in www.example1.com/watches.... the page is completely off, and about the same content as the rest of the site.. Now if i go to www.example2.com/watches .... ITS DEAD ON! I dont get it.... same page, different url... even though the second URL is pointing to the same data.
I find that ads match content pretty most of the time but there are short persiods (hours rather than days) when the ads are for some reason extrelemy untargetted. However, this usualy sorts itself out pretty soon.
