FAQ
Some questions that are likely to arise:
I can't find the codes, what should I do?
When searching for a specific code, make sure that you have no spaces before/after it. These are the default codes of Blogger and should be found in all the templates unless they have been modified by the template designer.
Why should I convert my AdSense code?
The Blogger's Template reads it as text and not as code so it is better to avoid any errors when trying to save it.
The ads are not displaying properly, why is that?
The ads could be affected by the styles (CSS) selectors (divs) containing them and some templates could be wrong designed, then you should consider modifying these styles, look for another relevant place or in extreme cases, change the template.
Can I put the all 10 codes on my blog?
No, you should choose just one of the locations where you want to put the ads considering that AdSense have some limits on the number of ads that could be displayed. Try to make a balance with your content.
Why there should be only 3 ads displayed on the main page?
This is due to the limit set by AdSense. Combine the type of ads (text, rich media ads and link units) if you want to show more ads.
Hopefully, this guide will be useful to those of you who need to display AdSense ads on your blog.
