Ad-Sense

To understand how to use Ad-sense you really need to know how it works...


So basically Google places ads onto your blog, that are paid for by advertisers.
These ads are very vague and text based, and all you have to do to add them to your blog is to add a gadget/widget to your blog. 
you can add these anywhere 
Especially if your using blogger
Steps to Add Ad-Sense to your blogger
1. Go to design in your blog settings
2. Go to add a gadget
3. Find Ad-Sense
4. You can add up to 3 of these gadgets to your blog
5. After this I would set up Ad-Sense for feeds (this puts an ad after everyone of your blogposts)


Now refine your ads and your blogs template to mesh well with the ads, you don't want them to distract from the rest of your blog...
