As of early October, Ardamis.com has its Google sitelinks back. I first noticed them back in July of 2009, when Ardamis had a toolbar PageRank of 6. Changes to Google’s algorithm later cost the site the sitelinks and reduced the PR to 5, which is how the site has appeared for the last year or so. Three months ago, in July of 2010 and one year after the sitelinks appeared, I noticed that all of the pages combined had over one million inbound links.
This is what a Google search for ardamis returns:
The second result returned, Final Fantasy XIII freezing on Xbox 360, is among my longest posts, has 91 comments, and enjoys some of the best inbound links of any page on the site, including from the forums at Xbox.com, Kotaku and GamesRadar.
The third result is my primary competition for the term ardamis, which briefly held the number one ranking a few months ago. That site has some one-line site links.
The actual mechanics of obtaining sitelinks remains a mystery, but there are plenty of people who are willing to speculate (and a few brave enough to promise they can deliver them for a price).
I’ve been posting more frequently, the site uses the WP-Paginate plugin and according to Google’s Webmaster Tools, the home page alone now has well over one million inbound links, but otherwise it’s been business as usual here.
I’m not going to speculate about how to get sitelinks or whether one or more of the changes in the last year was the catalyst, but Google does say to use descriptive and non-repetitive anchor and alt text in a site’s internal links and to keep important pages within a few clicks of the home page. These are very basic, fundamental things that any site should do, but it bears repeating.
