Koramangala, Bengaluru, IndiaPublished 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 Anything they do not publish is marked Not disclosed.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.

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 inquiries 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.
