The only way to really find this information out is to see the server logs (or analytics). I don't really trust a lot of the info Alexa provides, or any tool for that matter. According to compete (another popular SEO tool), FC Dallas gets more searches than Toronto and Toronto isn't even in the top 5 (yet somehow columbus is):

The Sitelinks probably are partly to do with traffic, but I think there are more factors than those. Some of which include:
- How many times the page has been accessed.
- How long visitors stayed upon the page.
- If a visitor scrolled down the page, or clicked on a link without scrolling down.
- Information retrieval scores for the page, along with an indication of how good a match the page may be for the query that was used in the search.
- The likelihood that someone might make a purchase on that page.
- Other information that might indicate that someone would be interested in the page.
