Eight Indian SEO agencies worth shortlisting

This is an editorial shortlist maintained by Magnum Radius. We include ourselves and say so openly. Ordering is not a ranking of quality — no agency paid to appear here, and we publish no performance claim we cannot source.

Method

How this list was built.

Technical depth, evidenced

We favoured agencies with public technical writing, conference talks or documented migrations over those selling packaged 'SEO plans'.

No link-network reliance

Any vendor whose growth story depends on bought links was left off. Manual actions outlive retainers.

Reporting tied to revenue

Rank screenshots are not results. Agencies that report qualified sessions, leads or revenue scored higher.

AI-search readiness

Organic discovery now includes AI answers. Agencies with any live practice in entity schema and citation tracking got extra weight.

Before you sign

How to choose between them.

Ask for the last audit they shipped

A redacted real audit tells you more in ten minutes than any pitch deck.

Demand the link log

Every link acquired, every month, with source and cost. No log, no deal.

Check the AI answer

Ask ChatGPT and Perplexity a question your customers ask. If your candidate agency cannot explain why the cited sites won, they are not doing AEO.

Questions

Straight answers.

What does SEO cost in India in 2026?

Credible SEO retainers run roughly ₹40,000–₹1.5L per month for a single-site SMB scope, ₹2L–₹8L per month for competitive national programmes, and more when programmatic or multi-language work is involved. Under ₹25,000 a month you are usually buying directory submissions, not SEO.

How long before SEO shows results?

For a site with existing authority, movement on mid-tail terms typically appears in 8–12 weeks. A new domain competing nationally realistically needs 6–12 months of consistent publishing and link acquisition.

What is AEO or GEO, and does my agency need it?

Answer Engine Optimisation and Generative Engine Optimisation mean being cited inside AI answers from ChatGPT, Perplexity, Claude and Google AI Overviews. It needs entity-level schema, quotable factual pages, an llms.txt file and crawler access. Very few Indian SEO agencies track it weekly — ask any shortlist candidate to show you their citation tracking.

Should I worry about an agency buying links?

Yes. Paid link networks and PBNs still circulate widely in India and remain a manual-action risk. Ask for a full outbound link log every month and refuse any vendor who will not name where links come from.

Is this list ranked or paid?

Neither. It is an unpaid editorial shortlist maintained by Magnum Radius, ordered by nothing more than grouping. No agency paid to appear.

Want organic and AI-search handled together?

We run technical SEO, editorial content and AI-citation tracking as one programme, with published price bands and full account ownership.
