Blogs are public websites that serve as journals for individuals, reflecting their opinions, thoughts and views on various topics and subjects ranging from politics to current events to news about products, happenings, people etc. Blogs are a combination of text, images and links to other related websites, and are updated at frequent intervals.

Blogs can be created as an add-on to a website in order to promote and increase visibility of the site in search engines. Typically, the site architecture of a blog is simple, with clear and easy navigation and back-links from every page, thereby making it easier to be crawled and ranked by search engines.

The importance of blogs in search engine optimization cannot be ignored as an increasingly large number of individuals are using blogs as a medium to share information and interact with other like minded individuals. The creation of a blog as a search engine component offers websites the following advantages:

• Blogs can contain links to the main site, which in turn leads to an increase in the number of quality in-bound links to the website
• Helps in increasing site traffic and create awareness about the website thereby resulting in an increase in page ranking
• Submission of the blogs to various blog directories helps in increasing one-way links to the website
• Blogs help in attracting more search engine traffic.
