Okay, so what is SEO? It's basically a process to improve the visibility of your site or blog in search engines' search results. One of the leading search engines are Google, Yahoo! and MSN. In general, the earlier (or higher on the page), and more frequently a site appears in the search results list, the more visitors it will receive from the search engine.
You can also update your site's searchability by editing your site's meta tags. Meta tags are descriptions of your site which search engines look for. But also, make sure that the tags you are putting in are relevant to your site's niche, otherwise, search engines will ignore your site because irrelevance to content.
You may also use useful tags for your blog posts. This way, Search engines can easily search for your posts. Think about it as 'keywords' or 'key terms'.
The searchability of your site is very important since not everyone knows your site url. So what you have to do is promote your site thru commenting and other site promotion methods. Another sure fire way is to register your site to open directories. At the start of your blog's or site's life, always remember that you should register them in these Open Directories especially in Google and Yahoo. From there on, build up your site's Google PR and Alexa Rank reputation. Constant updates to your site also tells the search engines that your site is alive.
One of the best methods I can think of is to attend seminars or workshops to learn more. I heard an event in the Philippines about a Google Insider Secrets to Search Engine Optimization seminar which will be led by a former Google Optimization Specialist. Learning the secrets from the master themselves doesn't get any better!
