One of the most important SEO feature is the XML sitemap generation. Without getting into a technical description of how XML works, the feature basically automatically updates the search engines when you add new content. I have seen this result in having new blog entries being indexed by search engines and appearing in search results within 10mins of being published!
Another feature I add is creating meta tags and urls that focus on the keywords that you would like to appear in the search engines for. By focusing on a few keywords, the website’s meta tags inform the search engine’s spiders that the website has a specific keyword niche. By continually focusing on those keyword within the blog titles and text, we are enforcing the idea that the website is relevant and authoritative to that keyword niche.
Of course paramount to the whole undertaking is to identify your keyword niche. Perhaps I will dedicate a blog post to finding your keyword niche.
