How to choose a digital marketing agency: the 2026 buyer's guide
How to brief a marketing agency, agree measurement before work starts, and check it follows UK and US rules on ads, reviews, influencers…
98 of 238 digital marketing companies ranked on evidence in the Q4 2026 edition.
E-commerce development is the engineering side of selling online: building the storefront and checkout, and integrating them with payments, stock, shipping, tax and whatever finance system the business already runs. It is distinct from e-commerce strategy or marketing, though many firms sell all of it.
Integration is where these projects succeed or fail. A storefront is a well-understood problem; connecting it to an existing warehouse, ERP or accounting system usually is not, and it is where the estimate moves. Ask specifically which integrations are in scope, whether they are off-the-shelf connectors or bespoke work, and who owns them when the upstream system changes its API.
Between them, the 238 digital marketing companies on this page cover eCommerce (180), SEO (174), digital marketing (164) and web development (161). They also list work in Mumbai, London, New Jersey and Bengaluru, India. 237 of them have written a profile you can read before you get in touch.
