SERP Features SERP features are any results on Google SERP (Search Engine Re- sults Page) other than traditional organic results that are intended to help users find the right information faster and with the minimum ne- cessity to click on the results. For pharmaceutical domains, however, eleven SERP features appear more frequently on Google. And of all the SERP features, “Image” ap- pears to be the most popular features by far with over 22 million times by all analyzed domains. In terms of domain categories, Hospital Networks/Healthcare pro- viders appear to be in the lead when it comes to taking advantage of SERP features on Google. For example, about 30% of “images” re- sult are accounted for domains in the Hospital Networks/Healthcare Providers category; while only 17% and 0.9% of images results have been shown for Pharmaceutical and Dental categories, respectively. A similar pattern is observed for other SERP features, with healthcare domains in the Hospital Networks category enjoying a far greater ex- posure compared to the domains in other categories. It’s also worth noting that the sum of all SERP features attributed to mayoclinic.org is 5,521,937, which is at least 1200% more than the to- tal number of SERP features shown for upmc.com (the second most successful website in terms of number of SERP features) in Google searches during the observed period.
