How to choose your
e-commerce search engine?

You're an SMB or independent merchant

Go for a solution with public pricing and quick integration. Vectail (from €29/month) or Doofinder are the natural choices. Avoid quote-only solutions that involve a long sales cycle.

You don't have a dedicated tech team

Avoid API-first solutions like Algolia that require significant development. Prefer a turnkey solution with a ready-to-use widget and script tag integration.

You want the best AI search quality

Bet on a solution built on top-tier AI infrastructure. Google Vertex AI Search for Retail is trained specifically on large-scale e-commerce data.

GDPR compliance is a priority

Choose a solution with data hosting in Europe. Sensefuel (France) and Vectail (GCP Europe) are the strongest options on this point.
