If you have written some highly successful articles, you should consider creating a page about yourself and then adding a link from each of your articles to your "author" page with rel=”author” in the tag.
Here is what google says about it at
Authorship markup uses the rel attribute (part of the open HTML5 standard) in links to indicate the relationship between a content page and an author page.
When Google has information about who wrote a piece of content on the web, we may look at it as a signal to help us determine the relevance of that page to a user’s query. This is just one of many signals Google may use to determine a page’s relevance and ranking, though, and we’re constantly tweaking and improving our algorithm to improve overall search quality.
A content page can be any piece of content with an author: a news article, blog post, recipe, review, short story …
An author page is a page about a specific author. For example, a news site might feature an author page for each of its contributors. The author page should be on the same domain as the content page.
To identify the author of an article or page, include a link to an author page on your domain and add rel="author" to that link, like this:
Written by <a rel="author" href="../authors/mattcutts">Matt Cutts</a>.
This tells search engines: "The linked person is an author of this linking page." The rel="author" link must point to an author page on the same site as the content page. For example, the page http://example.com/c.../webmaster_tips could have a link to the author page at http://example.com/authors/mattcutts. Google uses a variety of algorithms to determine whether two URLs are part of the same site. For example, http://example.com/content, http://www.example.com/content, and http://news.example.com can all be considered as part of the same site, even though the hostnames are not identical.
When I first read this I got excited that it would be a way to "register original content" with the search engines - but I now think that is incorrect. Here's how I think it might work....
Let's say you have authored 50 great articles about "small engine repair". All of those author tags pointing to your author page with your name as anchor text might establish you as an authority on the topic of small engine repair with the search engines. Then when you write article #51 google will remember that you have a lot of other great small engine repair articles and rank #51 at a much higher position immediately on publication. It would be like getting a big load of links right away.
That is just me guessing on how google might use this. What do you think?
