Vendar ranks 6 of 32 SEO agencies serving New York for ecommerce SEO: the ones with documented ecommerce SEO work on file, verified through September 2026. The top three by evidence-weighted score are Avex (79/100), Aumcore (59) and Amsive (57). No paid placements; every position below cites its sources. 26 more New York SEO agencies have no ecommerce SEO claim on file yet and are listed unranked.
Ranked agencies have at least one claim from an outside source that names ecommerce work: category and product-page optimisation, faceted navigation, Shopify or Magento platforms, or revenue from organic; official case studies and third-party reviews weigh most, profile tags least. Full rubric 2026.09 and the scoring model: How we rank.

Only Vendar profile tags name ecommerce SEO; no outside source on file yet.
Evidence-weighted ranking 2026.09.1: each agency is scored on the ecommerce SEO query from claims with sources. Evidence for this query 30 · Fit to this query 25 · Capability depth 15 · Reliability 10 · Transparency 10 · Reputation 5 · Market credibility 5, minus penalties; confidence is shown separately. Paid visibility never changes the order of a listing. The points, the claims and the limits behind every position are on its card above; the criteria, penalties, eligibility and ordering rules are on How we rank.
Catalogue sites are won on templates and taxonomy: category pages, faceted navigation, and what happens to a URL when a product dies. Traffic that does not convert is easy to buy and easy to lose.
