Until now, sitelinks have only ever appeared on the first search result, Google launched an expansion of sitelinks: a single row of links can now appear for results that didn't show sitelinks before, even for results that aren't in the first position. This means multiple results on one query can now have sitelinks. Up to four sitelinks can show up right above the page URL, instead of the usual two columns below the URL of the first result. This new feature means it's possible that your site will start showing sitelinks for a number of queries where it previously didn't.
