Smart Adsense

Usually, your links will lead directly to your home page. That’s where you see
your site as starting and that’s where you want them to enter.

But if the content the user wants to see is on one of the internal pages,
there’s no reason for them to have to click around to find it. Fill that page
with keywords that relate to the content on that page and it will have its own
search engine ranking — and well-targeted ads.

So if you have a site about cats and one of your pages was about cat food, it
would make sense to put plenty of cat food keywords on the page. That
would get you cat food ads and a high ranking on search engines when
someone does a search for “cat food” rather than just people who wanted to
know about “cats.”
