Where online stores move when they change platform.

The busiest routes

The 25 most common moves in the year. A route counts a store once, at the month it first showed up on the new platform.

All routes, including the ones with a single store, are in flows.csv, and month by month in monthly.csv.

Compared with the year before

The same count for the 12 months before, from the same crawl and the same rules. The number of stores switching platform hardly changed; where they went did.

WooCommerce to Shopify against Shopify to WooCommerce: 6.3 to 1 the year before, 7.4 to 1 now. The crawl covered 3.1% fewer stores than a year earlier, so the last column divides each route by the stores on its old platform.

Both years in year-on-year.csv. "Net" is stores moved in minus stores moved out.

Gains and losses by platform

How many stores each platform took in from other platforms and how many it lost to them. Stores that opened or closed without switching are not part of these numbers.

"Stores in the crawl" is the number of home pages on that platform in the latest crawl. It rises and falls with the list of sites the crawl visits, so read it as the size of the group, not as market share.

How often stores leave each platform

Stores that moved to another platform in a year, for every 1,000 stores on the platform. A low number means stores tend to stay.

Only platforms with at least 10,000 stores in the crawl, on average. The figure is a floor: stores that changed their web address when they moved are not counted.

WooCommerce and Shopify, both ways

The route between the two largest platforms carries more than a third of all moves, and it runs mostly one way. The size of the site before the move comes from its rank in the Chrome UX Report, which groups sites by how many Chrome users visit them.

A few moves have no rank because the site dropped out of the ranking in the month before it moved.

The data shows who moved, not why. If you are weighing the move from WooCommerce yourself, the migration scanner checks which of your plugins have a Shopify equivalent, and the cost comparison puts both platforms side by side, month by month.

How this compares with other counts

Store Leads, a paid database of online stores, also tracks stores that switch platform. For the 90 days to 18 September 2026 it counts 24,877 stores moving to Shopify and 17,504 leaving it, with 8,474 going from WooCommerce to Shopify and 5,903 the other way, about 1.4 to 1.³

Both counts agree on the direction: more stores go from WooCommerce to Shopify than back. They disagree on how one-sided it is. Store Leads follows far more stores, including sites with few visitors that the HTTP Archive never crawls, and it does not publish how it decides a store has moved. This count only includes sites busy enough to be in the Chrome UX Report, and asks for two crawls on each side of a move, which leaves out quick back-and-forth changes. Read the two together: Store Leads for the whole long tail, this page for sites with real traffic and a method you can check.

What this does not show

• Moves to a new web address. A store that changes both platform and domain looks like one store closing and another opening, so it is not counted.
• Small sites with few visitors. The crawl covers the sites in the Chrome UX Report, which only lists sites with enough Chrome visitors. Brand-new and very quiet stores are missing.
• Headless and hidden setups. A store whose home page does not show which platform runs it cannot be detected. Sites that show two platforms at once are left out.
• Why stores moved. The crawl sees the platform, not the reason. Agencies and merchants can tell you that; this data cannot.
• Market share. These are moves between platforms, not the number of stores each platform has.

How we counted

• The HTTP Archive visits the home page of every site in the Chrome UX Report once a month and records the technology each one uses. We read the mobile crawl from July 2025 to September 2026.¹
• For every home page and month we took the e-commerce platform it was detected on. Plugins and add-ons that sit on top of a platform, such as shopping-cart widgets, were left out, and Tiendanube and Nuvemshop, one company under two names, count as one platform.²
• A store counts as moved when the same address shows one platform in two crawls in a row and another platform in the next two. Asking for two crawls on each side removes one-off misreadings: only 10 sites in four months flipped to another platform for a single crawl and back.
• We checked a sample by hand. Of 90 stores counted as moved, 89 showed the new platform when we opened them in September 2026; one showed neither platform.
• The rate per 1,000 divides the stores that moved away by the average number of stores on the platform in the first and latest crawl.
• The year before is the same query with every date one year earlier: crawls from July 2024 to September 2025, moves first seen from September 2024 to August 2025.
• The query is in query.sql. We update the page every quarter.
