Adsense. You've all seen the ads (perhaps even clicked on a few), and now you want some of your own. They do actually make money - and not just for Google.
If you're already signed up to the Adsense program, it's a simple matter of copying/pasting into your Blogger template (I'll show you where in a minute) and rebuilding your site. They'll begin appearing in a couple of minutes or so, depending upon your content and the number/type/size of ads.
If you haven't already signed up, you've got two choices. Either follow the links via Blogger (beginning on the start page - pictured), or go directly to
www.google.com/adsense and sign up there. Once you've filled in the obligatory forms (free, and it only takes a minute), you're ready to go.
In the standard blogger template there are three main locations which are typically used for advertising. Naturally, you can put them anywhere you want; but we'll start with three spots. These are near the top of the front page (above the posts), in the sidebar and beneath each post. Using channels will enable you to test various Adsense combinations in each location. The template code should be modified as follows :
For the top of the page, look for the lines
<!-- Begin #main -->
<div id="main"><div id="main2">
The adsense code goes beneath these (make sure it isn't wider than the 468px options if you're using one of the standard templates).
To place Adsense ads in the sidebar, work out where you want them to appear. To place them directly beneath your profile, look for the line
<!-- End #profile -->
To make sure they appear on each archive page (as well as the front page), start with a <MainOrArchivePage> tag, then copy/paste the Adsense code, then finish it all with a </MainOrArchivePage> tag.
The third location commonly used is at the base of each post. To place the ads between the post and the comments, look for the lines
</MainOrArchivePage> <$BlogItemControl$>
</p>
</div>
and copy/paste the Adsense code directly beneath them. Once again, select an ad unit of no more than 468px if you're using one of the standard templates.
