Are you looking for an easy way to make money with your blog? Why not try Sponsored Reviews? I have been using it for about a year and a half now and have had good results thus far. I can definitely vouch for them and say that they DO pay - and ON TIME might I add! They pay on a bi-weekly basis via PayPal which is nice.

If you have a blog with a decent pagerank (PR3 and up) you can make a nice amount of money per review. Depending on how your blog ranks in their system, they will give you a price range (min - max) that you can choose to charge for your reviews.

Each day their list of opportunities is updated with requests from advertisers. You can then choose which opps you want to bid on and the amount that you want to bid. Each offer will have a different max bid amount. It's better not to bid that max amount unless you have a highly ranked blog! If an advertiser does not like your bid they can decline or make a counteroffer with a lower cost.

For more FAQs you should definitely check out their help section. If you are looking to make blogging a career or even if you just want to make some extra cash each month, Sponsored Reviews is definitely worth your while.

If you're looking to build buzz about your website or a new product, etc Sponsored Reviews can also help you with that! Plus, since you can name your own price, it's easy to stay within your budget. I really wouldn't go below $5 though because bloggers only receive 50% of the bid price and honestly, $2.50 is not worth it for most of the listed opportunities.

Good luck!
