AdSense formats
Google offers lots of formats for your ads. I can't show them in this post but you can find out more about them at https://www.google.com/adsense/static/en_US/AdFormats.html
You should pick the one that fits in best with your existing page structure unless during the review process you decide to undertake a major re-vamp!
Google allows multiple formats across your site but until recently only allowed you to place one block of ads on each page. This has now increased to 3 blocks on the same page. Having said that it is your responsibility to check that how you are using AdSense complies with Google's rules and they do change from time to time.

As soon as you enter your adsense account and clicked on Adsense Set Up buton and then to Adsense for Content,You will come to the Ad_Formats wizard. Google has produced different Ad Formats viz 1.Horizontal 2. Vertical and 3. Square.
Inside these three headings, there is also different formats which you can use according to your website or blog.
1.Horizontal
i) 728 X 90 Leader Board,
ii) 468 X 60 Banner,
iii) 234 X 60 Half Banner.
2. Vertical
i) 120 X 600 Skyscraper,
ii) 160 X 600 Wide Skyscraper,
iii) 120 X 240 Vertical Banner.
and
3. Square.
i) 336 X 280 Large Rectangle,
ii) 300 X 250 Medium Rectangle,
iii) 250 X 250 Square,
iv) 200 X 200 Small Square,
v) 180 X 150 Small Rectangle,
vi) 125 X 125 Button.
Color schemes
Google lets you specify what colors the ads will appear in and there are two schools of thought about what is best. You can design ads so that they fit well with your existing web design. Or you can make the ads stand out strongly by choosing a markedly different color palette.
You can now get sufficiently high resolution statistics from Google to find out which ads work best on your site.

Google has pre-designed colour palettes from which you can make your ads suited to your website or blog.
Pasting code
This is either easy for you or difficult! If you routinely look at the HTML in your web pages, the process is straightforward: just locate where in the page you want the ads to go and paste the code in.
If HTML is a foreign language you'll need some help to begin with. Practically, the best way forward is to experiment a bit. Put the code in, have a look at the page (and Google will immediately start posting ads on the page although they may not be context-targeted to begin with - more on this later.) If you like what you see, stick with it. If not, move it around, use a different format (go back to your AdSense control panel) and do it again.

What happens next
As soon as your new page is viewed, Google gets alerted to its existence and sends out some ads. Now if Google doesn't know anything about the page you will see so-called Public Service ads which are about charities and so on. However, in around 15 minutes (it's that fast) you will start to see ads that are context-targeted. They will be more relevant to your page.
But this will only happen if Google can work out what your page is about, so check that the copy makes it clear and that the page title, headings and meta tags are consistent and valid.
You can see the loads money coming UP.
