I will likely rub a few people the wrong way here but I actually recommend blogger for an adsense site under the right conditions! Here is why

note: These recommendations are for using blogger with a TLD

With blogger you can host your site with google, that means you don't actually need a hosting account. If you are brand new to making niche sites you can just pay for the domain ($10 bought through your blogger dashboard) and that's it, hosted free by google

Blogger is owned by google so it seems they favor domains hosted with them. I certainly did notice that my site got indexed VERY quickly

Blogger offers an adsense widget for EASY integration, good for newbies, but I recommend inserting your own adsense block into the code for the best CTR

Good for set and forget sites! I built a site on blogger about 8 months ago (one of my first niche sites) and have not updated it since, I average about $650 per month off this site! If I had this site on wordpress I would have had to update it to the newest version every few weeks!

Summary
Blogger is good (I ONLY recommend blogger if you get a TLD with it) for

• A site you want to build and let it sit
• A site where you don't need A LOT of options
• If you are just going to put adsense to monetize
• If you are newer, and just want to build a small site without buying a new hosting account

For most of my new sites I am using wordpress because I am building them out and like all the options, but I have 3 sites hosted on blogger that are making me good money.

Have you had success with blogger?
