A blog is essentially a journal that is available on the web. The activity of updating a blog is "blogging" and person who keeps a blog is a "blogger." Blogs are another way to spread your message and get people to see your content. Anyone who can write, read and uses the computer can start a blog. It is like writing down your ideas, beliefs and experiences or about products on a virtual paper.

Blogging and traffic go together, and it is easy to create a blog to drive traffic to your website or any other online web page. Each time a blog is updated, an RSS feed goes out and "pings" search engines, so it's an excellent way to stay at the top of search results.

It is essential to update a blog frequently so as to get good traffic or regular readership. This will ultimately lead the blog to be enlisted with search engines and might also become a good source of your extra income. You can try pay per click (PPC) advertising which pay you anywhere between a few pennies to a few dollars every time someone clicks on an ad. There are several options including the highly popular Google AdSense, AdBrite and Clicksor. There are many good programs to join out there, so look around and you will find something that suits your blog profile, content and target audience. These ads are easy to signup for and you can run them on most blogs.
