Blogging is an excellent advertising tool because each post is indexed separately in search engine results pages. Each post also has its own set of keywords, making them more visible online.

This is why some businesses are willing to pay hundreds of dollars to bloggers for sponsored product reviews.
If your blog has a respectable viewership, you can certainly tap local businesses in your area if they will be interested in a sponsored review. The payment will depend on the number of your websites audience.

Alternatively, you can join blogging and advertising networks (e.g. Social Spark and PayPerPost) where you can immediately connect with interested companies who want to get advertised.
