The following elements also seem to influence whether Google displays Sitelinks or not: (but there is no clear science or guarantee that you can get Google sitelinks by following any formula.)

• Your site needs have a a pretty stable top ranking for the searched keyword. Other Web sites coming up in lower spots don't ever seem to be awarded Sitelinks.

• The number of searches and the number of clicks that your website gets, for that certain keyword phrase seem to also be an influence.

• The number of links that point to your website with the searched keyword as the anchor text seem to influence the creation of Sitelinks.

• Sitelinks only seem to appear for the major primary keyword phrase of a website, but not for all keywords.

• If your website meets these criteria Google might assign Sitelinks to your website for your most important keywords.

• Sitelinks can be a very nice bonus for search results.

•  Google seems to prefer links near the top of a web page.
•  Sitelinks usually only appear for more general search phrases.
• Sitelinks do show up most often on brand related searches.

Which links does Google choose for the Sitelinks?

You'll notice that they always seem to be first level links on any website. In other words, any links not included on your homepage won't be used as Sitelink criteria.

• Unpopular Keywords that are not searched too often don't get Sitelinks.

• Older Web sites seem to be awarded sitelinks more than newer sites.

• It also seems that your website has to get a certain volume of clicks for the searched keyword.
