Anyone that has spent time trying to improve their click through rates (
CTR ) from search engine results pages (
SERP s) will tell you that Google algorithmically picks the snippet displayed for a given page; it’s not something you can always control. Unfortunately, Google doesn’t always display the snippet that will give you the best conversion rate.
However, the use of microformats, a set of agreed upon
HTML conventions used to describe content, can give you more control of the snippets displayed in Google
SERP s. Once your site is properly using rich snippets, you will see them also appear in your Google custom search and Google site search results, so this technique is definitely worth exploring if you use those tools as well.

Interested in getting started? Well there’s no reason not to start using microformats as much as possible already; semantic markup is always good for search engine optimization:
- Update your markup (make sure it’s valid) and use the Quix bookmarklet to check your page, by entering ‘snippet’ to submit the current page to Google Rich Snippets test tool.
- Getting the “Insufficient data to generate the preview” error? Then make sure that there are no errors in the markup (go back to step one) or check that you are using enough data to generate the snippet preview, so check the microformat syntax again.
- Finally, let Google know that you’re an early adopter.
So who’s using microformats in this and other ways? Brands like Mashable, Yahoo!, Yelp, Technorati, SearchMonkey, LinkedIn, Urbanspoon and many more. If you’re interested in digging deeper into the future of microformats as they relate to web analytics as well, Dennis Mortensen from Yahoo! has a great post on what the future may hold.
