Searchmetrics, a digital marketing provider, has released a study of the top car rental providers in Google searches.

When searching for car rentals, Enterprise.com took the top spot for the most visible website in Google U.S. organic search results. For Google’s U.S. paid searches, kayak.com gained the highest mark, according to the study.

Searchmetrics analyzed the sites that rank in the top 10 organic and paid search results for a list of the 360 most popular search terms related to car rentals in U.S. and U.K., Germany and France. It used this data to calculate the SEO visibility and paid visibility scores — index values developed by the company to measure how visible and prominent sites are within organic and paid search results, respectively — for each site.

The study’s data was taken at the end of August from the global search and social media database, which Searchmetrics operates to power its online software tools, says the company.

"These days, a big portion of people who want to get a hired car start their search for a rental company online through a search engine, so for car rental brands, travel portals and price comparison sites being visible for the most popular keywords for car rentals on Google is hugely important," said Marcus Tober, CTO and founder of Searchmetrics.
