Which one is better, "mypost98.html" or "anniversary-gift-how-to-choose.html"? This time latter is better because it includes keywords and hence get better chance to be listed in high rank in search engine.

Certainly there is a search engine friendly blog templates. To know whether your blog template is search engine friendly designed, go to Crawler simulation (It's free.) Enter your blog URL and then it'll show you how it looks like when a search engine spider visits your blog site. If you see a lot of html code or java scripts before you see main content, it means your blog is not well designed in point of search engine optimization. There is a way to hide unnecessary code from spiders, using CSS or div class "hide". Try to make your title tag immediately after head tag and to show up your body content as near to head tag as possible.

How to construct your blog search engine friendly?
Make your blog site structure as simple as possible. This may not be a big issue for bloggers because unless a blogger can design her/his blog system, they have to use a default system. What I mean by this is that most of blog system make permalink be for example, "www.blogcom.com/user/archive/year/month/date/apost.html". See how far final "apost.html" is from root. It's 5 step further. This is not so good in terms of search engine optimization. You can reduce those steps but you only can do so one or two step because database recognition is concerned behind this story. So bottom line is that try to make your blog simple but if it's not possible, focus on writing good content. I observed many top bloggers have a bit complicated permalink system yet have lots of traffic.

But if you can make your blog structure simpler without problem, please do so because it is much better for reader and search engine as well.

Ping your blog

Do you ping? Many pongs will come,then. :-) This may not be an issue if you're using Movable Type, WordPress, Typepad, or Drupal 4.6.0. But consider pinging to Ping-o-Matic!, if your system is not configured to do so. Because it pings to most of important blog search engines and directories in one spot. If your blog application doesn't support to ping automatically to "Ping-o-Matic!", you can do so manually by visiting Ping-o-Matic! Once you type your blog name, blog URL, check where to ping and click "submit ping" button, and don't forget to bookmark. It gives you a convenience because you don't need to type blog name, URL and check where to ping again.

By pinging you make search engine spider crawl you more frequently and make your reader notified faster.

So far you have most important SEO techniques for your blog. Say, how to use your keywords and where to enter, search engine friendly blog template design, structure and finally ping to "Ping-o-Matic!" But one thing is missing!

Get inbound links!

Probably it is as important as your blog itself! You can read about this at Traffic to Blog: Part 4

Provide internal link within your blog.
If you have related post to other post, link each other within your blog content. This helps your reader find more information out of your blog, stay with you longer and even come back to you again.
Furthermore, it is one of SEO techniques. By doing inter link you can have more back links, though they are less valuable than external inbound links. More technically it can be used to improve page rank of certain blog. For example, suppose you have 5 related post, 4 have page rank 4 and other page rank 0. If you want to increase that page rank of 0, you link all other 4 posts to that post. It'll surely improve page rank of lowest one. But be aware that when you link back higher page rank post may not keep original page rank. So do it under your plan and do it moderately. Don't abuse this technique because search engines may consider you as a search engine spammer.
The bottom line is that moderate is always good.

In second bullet, I wrote "You provide new information and they will come." Oops, it's WRONG! They don't come. They don't know whether you provided new information at all. You have to let them know you wrote new information. This is related to topic that how to optimize your post search engine friendly.
