The advantage in knowing html code

I just teached my wife set up her blog. Then cam the portion on Adsense. While within blogger, there is an adsense function, it is pretty limited in helping to increase her chances of getting ad revenue. I have to guide her thru Adsense account to get her to add in adsense advertisement. Also the ads placement requires some understanding of html code which she knows nothing.

 

Then there is this thing about channel where you could monitor your ad performance from various blogs if you have more than one.
