Reports are coming from WebmasterWorld and DigitalPoint Forums that more sites are obtaining those much sought after Google Sitelinks. Now that you can get up to 8 Sitelinks for your listing, people simply want them.
My web development company now has them, a search for rustybrick returns 4 Sitelinks beneath the main listing. A couple weeks ago, I did not see Sitelinks for my listing (I believe). The search engine roundtable Google search returned Sitelinks almost since the beginning. Notice how the rustybrick example only shows 4 Sitelinks:
But if I login to Google Webmaster Tools and view the Sitelinks section for that site, I see 6 available links:
In any event, there are some rumors it takes a few weeks for the Sitelinks displayed in Webmaster Tools to update to the main Google search results. Sitelinks is a bit too early to have hard evidence like that and I would suspect, Google would want to make that transition as soon as possible. So we will see.
