Etsy Inc. joined the Mobile Speedometer big leagues this week.

For the week ending June 12, the online marketplace for handmade goods jumped up four spots to No. 5 from No. 9 the previous week.

The Mobile Speedometer is a weekly performance index ranking 19 mobile sites by speed. Catchpoint Systems Inc. provides the Mobile Speedometer performance data about how fast mobile home pages load exclusively to Mobile Strategies 360.

This is the first week Etsy has ranked in the top five mobile sites, as it ranked No. 9 the previous week and No. 13 for the weeks ending May 29 and May 22.

Etsy shaved 0.24 seconds off the time it takes for its mobile site home page to load to 1.73 seconds from 1.97 seconds, according to Catchpoint Systems. The index average is 2.11 seconds. The retailer did not respond to a request for comment.

WebMD Health Corp., a big provider of medical content to consumers and physicians, also improved its mobile site speed by reducing the load time by 0.15 seconds.  It also reduced its page weight significantly to 1.84 megabytes compared to 1.94 megabytes the previous week, according to Catchpoint Systems.

The mobile site also had fewer items on the homepage, 130 compared to 200 the previous week. Even so, WebMD.com remained near the bottom of the index at No. 16, the same as the previous week. WebMD did not respond to a request for comment.

Across the index, most sites performed a hair slower for the week ending June 12, Catchpoint says.

The Mobile Speedometer index monitors 19 sites across travel, retail, financial services, dining and entertainment, and healthcare. The 19 mobile sites were selected by the editors of Mobile Strategies 360.

Catchpoint Systems monitors each mobile website’s home page with measurements taken from 27 Catchpoint Systems backbone monitoring nodes across the U.S., at intervals of two minutes between Sunday to Sunday each week. Backbone monitoring nodes are the locations of Catchpoint’s devices that are near data centers of the main internet service providers that provide service to a city. The nodes simulate end-user contact with each website. Catchpoint monitors webpage load time, availability, hosts and items.

They are defined as follows:

Webpage load time: The time it takes for enough page elements to load for a consumer to begin interacting with a page, such as searching, tapping or scrolling. From a consumer point of view, the time it takes for the progress bar or spinning wheel to stop.

Availability: The percentage of time during the test week that the site can be successfully reached by a consumer.

Host: Any domain that delivers data, content or services over the internet to the site.

Items: Also known as requests. Webpage components, such as files or images, that a page loads from internal and external hosts or domains. These can include PDFs, PNGs, JPEGs and GIFs.

The companies are ranked each week based purely on their webpage load time on 4G networks.

For the week ending June 12, the average mobile site page load time was 2.11 seconds, the same as the previous week. The mobile site average page weight was 1.07 megabytes, the same as the previous week. The average number of hosts was 23.00 compared to 23.43 the previous week. The average number of items on the home page was 81.75 compared to 81.40 the previous week. And the percentage of the time the mobile sites were available was 99.92% compared to 99.82% the previous week.
