Agencies worth talking to if you are shortlisting a digital marketing partner in Kolkata, with what each one is good at and where they sit. Kolkata has a smaller agency market than the western and southern metros, but a long established one, and rates are generally lower.
We publish this page, so rather than scoring ourselves against the agencies below, here is what we do and you can judge for yourself.
We get businesses found on Google and named inside AI answers. SEO, content and the website itself, handled by one team rather than three vendors.
Koramangala, Bengaluru 560034Published by SEO Sadhu · we publish this page, so we have kept ourselves out of the ranked list below.Four things decided who made it, and one thing decided how we present ourselves.
An operating office in the city, not a nameplate address on a national website.
Everything we list comes from the agency's own site. Anything they do not publish is marked Not disclosed.
Agencies that are visibly better at something specific, rather than listing every service in existence.
Named clients published by the agency, not logo walls with no names attached.
Sorted by nothing in particular. Anything an agency does not publish is marked Not disclosed rather than guessed at.

Most of the Kolkata agency market sits in one place: eight of the ten agencies here are in Salt Lake Sector V.

TechShu, the digital marketing arm of Indus Net, runs a service list from SEO and PPC to CRO, marketing automation and white-label marketing. It lists further offices in Mumbai, Chennai and Hyderabad and several overseas.
PromotEdge is an integrated creative and digital agency in the Ambuja Neotia EcoCentre. It covers brand strategy, creative design, web, digital marketing and audio-visual production.

Six questions worth asking whoever you shortlist.
Strong at D2C performance marketing does not mean strong at B2B SEO. Shortlist for your actual bottleneck.
The people who pitch are often not the people on the account. Ask, and ask how many other clients they carry.
Ask for a redacted monthly report. If nothing in it connects to enquiries or revenue, expect an awkward month four.
Buyers now ask assistants before search engines. Ask how they get clients named in those answers.
Notice period, and whether your ads account, analytics and website stay in your name when you leave.
Nobody controls Google. A promised position means they misunderstand that, or expect you to.

The agencies are presented in no particular order of merit. Every fact about them comes from their own website, checked in September 2026.
