Technology and information blog

#1 - Comments Should be Enabled !
Some WordPress users restrict comments to registered users, or disable them entirely. While this may be appropriate in some situations, in most cases comments are a very beneficial factor, and a defining mark, of a blog.
Comments engage your readers, help you get more “fresh content” SEO brownie points, and give search engines another reason to come back frequently.
#2 - Blog Should Have A Topic !
Some of us would prefer to have a blog where we talk about anything that comes to mind: cars, movies, photosynthesis, dust mites, you name it.
In and of itself, such a blogging style isn’t wrong; however, you can leave search engines clueless as to what your blog’s about and thus for what search queries your blog should appear. And some of your readers might get annoyed in the process as well.
#3 - Use Images in Your Posts !
Not only do they increase visitor attention and retention, they give you an opportunity to use keyword-rich “alt” attributes, “title” attributes, and filenames. Plus it’ll give your blog visibility in image search engines like http://images.google.com !

#4 - Write Right Post Titles !
SEO isn’t everything: once you’re high in the SERPs, you need action words to prompt clickthroughs.
Put keywords in your title if at all possible, but not if it’ll compromise the click-trigger action title.

#5 - Integrate Social Media !
* Digg
* Sphinn
* StumbleUpon
* Mixx
* Scoop
Ahh.. You know What I mean..
#6 - Install the Google XML Sitemaps Generator Plugin
XML Sitemaps are search-engine-friendly directories of your blog’s posts and other pages intended to help search engines spider your site. Though pioneered by Google, they’re supported by Yahoo, MSN, and Ask.com as well.
The Google XML Sitemaps Generator for WordPress makes creation of these sitemaps easy and automatic. It also lets the engines know when you post new content.
