There are many purposes for blogging, like public service, expression of opinions and views, etc. If you want to get Google's attention, blogging can provide new content to your site on a consistent basis. Google favors dynamic sites, giving them higher positions than those that are inactive.

Locations to post/publish your Blog: There are multiple services available on the Internet for those who don't already have a blog. WordPress.com and Blogger.com are two of the most popular ones. Yahoo.com as well, has begun to obtain a chunk of the blog pie. A traditional practice is to install your blog in a folder titled "blog" on your site, assuming you already have a website. It may look like: mydomain.tld/blog/

Blog Software: Try WordPress for blogging if you already have your website hosted. In addition, you can compose blog articles on Blogger and then post them up on a site that you own, via FTP.

Content: In order to be effective, a blog must have quality, informative, original and dynamic content. This means that you cannot plagiarize other people's work, with the exception of brief excerpts that corroborate your article. Don't forget to give credit to the original author. In addition to this, your blog must be updated on a regular basis.

Reader interaction: You can let readers leave feedback by setting your blog to allow it. This gives you control over your blog and comments. This facility is necessary to protect you from current and future spammers. In addition, those who disagree with your opinions may post unsuitable comments.

How to gain blog visibility:

1) Fresh and original content

2) Obtain Backlinks

a.) join webrings,

b.) partake in social networking (Twitter, Facebook, Myspace, etc.),

c.) Look for forums that have similar interests as you do. It is possible to find forum communities at places like Yahoo, Yuku and Aimoo, among others.

3) Submit your URL to Google and Yahoo. If you utilize WordPress, you can download an XML Sitemap generator plug-in (it does not cost anything, but donations are appreciated.)

4) Make use of "tags" in your articles. Use keywords when making tags in order to let crawlers like Google be aware of the best place to classify your blog posts.
