"As I read here (http://en.support.wordpress.com/advertis... there are options to do that. Is it difficult?" No, it is not difficult to me. However, the question is, what kind of ads you want to put? Most blogger use Google Adsense, and it's not allowed to put in a wordpress.com blog, as stated in that page. So if you think you don't use Adsense in the future, then it is not difficult.

My recommendation (based on experience): You will love having adsense in your blog.

"Should I try WordPress or anything else por those purposes? " => You should stick with wordpress, but set up wordpress.org in your host, you will have 100% control of your site, you can put any ads you want, you can put any content you want.

However if you are not ready to have a self-hosted blog (wordpress.org) then use blogger, they will allow you putting any ads.

WordPress is very simple. If you're not super tech savvy, stick with WordPress or Tumblr - these are two great options. The are also nice because you can communicate with other bloggers who sometimes follow, and reblog your posts - for even more exposure!

Wordpress is very popular with marketers due to the easy site setup process, there are plugins that work with popular ad networks, like Adsense. The free Wordpress.com host charges upgrade frees for you to use your own domain name

You typically have to own your site domain name to qualify for an ad network, there are exceptions like Google's own Blogger.com which allows Adsense on a free subdomain.

challenging stuff browse from search engines like google this could help

Hi!

I wanna open a web site of people writing about politics, I also have the idea of putting ads when we turn popular. As I read here (http://en.support.wordpress.com/advertising/), there are options to do that. Is it difficult?

Should I try WordPress or anything else por those purposes?

Thanks
