Putting ad code isn't accepted in wordpress.com. Are there other ways to make money with wordpress.com blog? How is the effect? Thanks.
You can put Adsense code to the WP. I personally use it. Look for sidebar.php or footer.php and make sure they work with the Adsense. You can promote affiliate programs by using the WP.
I think the thread starter is talking about the free wordpress subdomain. We can't put ads in free WP blog. Anyway, I suggest you try blogspot, you can put ads there. Also, I prefer to buy my own domains instead of using free sub domains.
Or you can go to the second link in my signature and get FREE BLOG (OR ANY WEBSITE) HOSTING and a FREE TOP-LEVEL (.com, .net, .org, etc) ABSOLUTELY FREE!! Check it out, or don't and continue to pay for something you don't have to...
Yes, there are other ways, such as affiliate links or selling text links or blog posts. Your blog gets deleted. (Just to clarify, you're not allowed to make money through wordpress.com, so don't try it or your blog will be deleted.)
Here is one article that might help http://www.caroline-middlebrook.com/blog/a-simple-strategy-to-make-money-online-with-wordpress/
This isn't the answer to OPs question. Direct sources of income: -sell it on the black market -private link sales (like on DP) Indirect: -use it for SEO of your other sites - those which have ads
wordpress.com isnt suitable for making money but they are real good for your SEO, it is extremely easy to get high PR using wordpress.com, link it to your own sites to help with your SEO. Making money wise, it s not allowed.
You should either do self hosting or if you use Blogger, it's a lot easier to just plug Adsense in... they have it built in for you.
I would recommend self hosting as the best choice there is so many free hosting around with cpanel or fantastico but that is not the OP question, he is asking how to monetize using wordpress.com
You can just use it for linking purpose through the blogroll, better if blog with your own domain name.
