If you already have a blog and want to start getting paid to blog, then you might want to have a look at Smorty. They are a service that connects advertisers and bloggers. Basically an advertiser can sign up and
advertise on blogs by paying bloggers to write a review of their site or a particular products. The advertiser will specify relevant keywords and request a link to their website.
As a blogger you can sign up and submit your blog for approval. There is no limit to the number of blogs you can add, the only specification is that they are at least 30 days old. Once you have added a blog and it has been approved you can start blogging for money. Simply log in to your Smorty account to see what opportunities are available. All you need to do then is to choose which opportunities interest you and write at least 150 words on the subject. Once the post has been approved Smorty pay you by Paypal after seven days.
