How results are ordered

By the number of client brands each agency names on its own site, then by how many of those we corroborated. That number reflects how much of its portfolio an agency publishes and how much our crawler could read. It is not a quality rating.

Sponsored listings appear in a separate, labelled block and never change this order.

How this directory works

Where agencies come from

Agencies are found in Google search and business-listing results for ecommerce agency searches, and through agencies submitting themselves. Each agency's own site is then read to record its services, platforms, sectors, offices and the client brands it names.

What “named clients” means

A named client is a brand the agency names on its own site, usually in a case study or portfolio. It is the agency's claim. Where the client's own site or technology stack backs that claim, the client is marked corroborated (✓).

How platforms, services and sectors are assigned

From what the agency's pages describe. A sector is recorded when the agency's named clients sell in it or the agency explicitly describes that work, not from a single passing mention.

Locations

Only a head office or office found in a business listing with an address, or named on the agency's own site. An area an agency says it serves is not treated as a location.

Order and payment

The default order is by number of named clients, which reflects how much of a portfolio an agency publishes as well as its size. It is not a rating. Sponsored placements appear separately and labelled. Self-submitted listings are paid for and are ordered the same way as every other listing.

Corrections

If a listing is wrong, email hello@ecommerceguide.com with the page and the correction.
