using large keyword lists can help boost your AdSense revenues by simply allowing you to create more pages.

Find out which keywords are your money terms these will be keywords that have a mix of good demand numbers and high PPC bid prices. If you've done
your homework right in picking a profitable niche, you will find that there will be a few major keywords that have both high demand and high bid prices.
Here are some 'general' tips on putting AdSense (or other contextual advertising) on your website:
Put your keywords in the title tags of your pages this goes a long way towards determining the "topic" and "context" of a page. If you're using blogs, then put the keywords in your post's title.
Put keywords in the content of your pages this is similar to what I talked about in my last article on on-page optimization. Spread the keywords naturally, and if possible (i.e. if it fits in with the theme of the page), use them in <h1> tags as well.
Stick to one topic per page (or one keyword per page). This allows you to write focused content that in turn makes it easier for AdSense to serve ads based on your chosen keywords.
If you are putting AdSense on a website for the first time, don't be too upset if you get irrelevant ads in the beginning sometimes it takes a few days for the AdSense crawler to get things right regarding your website, especially if you have pages that are not too focused on their keywords.
