The work you genuinely buy once
This is the half of SEO that behaves like a capital purchase. You pay for it, it goes into the site's foundations, and it keeps working without further payment until something structural changes.
Prices below are typical Indian agency figures for the work bought as a project rather than inside a retainer. Ranges are wide because site size and stack move them a long way — a redirect map for 200 URLs is an afternoon, and for 40,000 URLs it's a fortnight.
| Bought once | Typical one-off cost | How long it holds |
|---|---|---|
| Information architecture and URL map | ₹40,000–₹1,20,000 | Until you replatform or restructure the catalogue |
| Redirect map for a migration | ₹30,000–₹1,50,000 | Permanently, as long as nobody deletes the redirects |
| Schema markup built into templates | ₹25,000–₹75,000 | Until the templates change or Google retires the type |
| Title, meta and heading rules at template level | ₹20,000–₹60,000 | Until someone edits the template without telling you |
| Core Web Vitals work in the template layer | ₹50,000–₹2,00,000 | Until the next heavy script is added — often only months |
| Analytics, Search Console and conversion tracking | ₹25,000–₹60,000 | Until the site, the tag manager or the CRM changes |
The work you rent
Everything below is recurring, and it's recurring for one reason: SEO is a relative position. You're not meeting a standard. You're staying ahead of specific competitors who are also publishing, also earning links, and also fixing their site — on an index that gets rewritten by core updates several times a year.
Prices here are what each stream costs when bought on its own. Inside a retainer you're not buying all of them at full pace; you're choosing which two or three run this month. That's the real reason a ₹75,000 retainer can't do everything a deliverable list implies.
- Content is rent because competitors publish. A page that ranked third in January is fourth in June because two better pages appeared, not because yours got worse.
- Links are rent because authority is relative. Your profile can grow and your relative position still fall.
- Technical is rent because your site is alive. Every release, plugin update and new product page is a chance to break something that took months to fix.
| Rented monthly | Typical monthly cost | What happens when you stop |
|---|---|---|
| New content on queries you don't own yet | ₹20,000–₹60,000 | Your ranked query set stops growing; competitors take the gaps |
| Refreshing pages that are slipping | ₹8,000–₹25,000 | Anything with dates, prices or 'best of' framing decays first |
| Earned links and digital PR | ₹15,000–₹50,000 | Your referring domains flatten while rivals' keep climbing |
| Technical monitoring and fixes | ₹8,000–₹20,000 | CMS updates, plugin changes and new SKUs quietly break things |
| Reporting, analysis and planning | ₹8,000–₹15,000 | Nobody notices a core update until revenue does |
The split on a first year, in rupees
On a ₹75,000-a-month engagement, the first year costs ₹9,00,000 ex-GST. Roughly ₹2,00,000–₹3,00,000 of that is the buy-once block, and almost all of it is spent in the first four months. The remaining ₹6,00,000–₹7,00,000 is rent — content, links, monitoring, reporting.
Which produces the useful observation about year two. If nothing replatforms and no new market opens, the buy-once portion of the budget is close to zero. The same site can often be held and grown for 70–85% of the original retainer, because you're now paying for production rather than diagnosis.
Most proposals never mention this, for reasons that don't need explaining. It's still a fair question to ask at month ten, and the right way to ask it is specific: which workstreams from month one are finished, and what does the retainer look like without them? A good agency has a real answer. Sometimes the answer is a reduction; often it's a reallocation into something you weren't funding before, like digital PR or conversion work. Occasionally it's honestly "more", because organic became a real channel and widening the target set now returns better than shrinking the bill. The month-by-month shape of the spend works through all three cases.
Two kinds of site that can genuinely stop after six months
This is where most SEO writing goes evasive, because the honest answer is bad for agency revenue. There are two real cases, and if you're in one of them you should stop paying a retainer.
One: a single-location local business in a settled market
A dental clinic, a salon, a diagnostics lab, a small repair business — one location, a service area that isn't growing, a correct and complete Google Business Profile, twenty to thirty solid pages, and no funded competitor moving into the area.
Once the map-pack position is earned and reviews keep arriving naturally, the ongoing work is genuinely small: keep the profile accurate, respond to reviews, post occasionally, and don't break the website. That's an hour or two a month, and the owner or a staff member can do it. Paying an agency ₹15,000 a month to maintain that state is paying for insurance you probably don't need.
Two: a narrow B2B or industrial niche where almost nobody publishes
Specialised machinery, a technical component, a compliance service with a handful of Indian suppliers. Search volume is low — sometimes forty searches a month — the competitive set is static and has been for years, and nothing new enters the index because nobody in the category writes anything.
Rank a genuinely useful set of pages here and they'll hold for a long time, because there is no one to displace them. The right spend is a well-executed project and then near-nothing, with a review once a year.
What ends both cases
- A funded competitor enters. One rival hiring an agency changes the maths in a quarter.
- You replatform or redesign. Every foundation item in the buy-once table gets invalidated at once.
- A marketplace or aggregator moves in and starts occupying the results you held.
- AI Overviews start answering your query directly, which compresses clicks and changes what a top position is worth.
What actually decays first when you stop paying
Stopping SEO does not produce a cliff. It produces a slope, and the slope is gentle enough at first to be mistaken for proof that the retainer was unnecessary. Here's the real sequence.
- Weeks 0–8: nothing. Rankings hold, traffic holds, and it genuinely looks like you got away with it. This is the window in which most businesses decide SEO was a waste of money.
- Months 2–4: freshness-dependent pages slip first. Anything with a year in the title, a price, a comparison or a 'best of' framing loses to a competitor who updated theirs. These are usually your highest-converting pages, which is the unpleasant part.
- Months 3–6: average position drifts before traffic does. Queries where you sat fourth to eighth slide out of the visible results. Your headline traffic number barely moves, because your top few pages are still holding — which delays the alarm.
- Months 6–12: relative authority falls. Your referring domains stop growing while competitors' keep climbing. Nothing was lost; you simply stopped moving while the field didn't.
- Any time, without warning: technical rot. A theme update strips your schema. A plugin change adds noindex to a template. A new product feed generates 4,000 duplicate URLs. None of this announces itself, and with nobody watching, the first signal is a revenue drop months later.
- Any time, worst case: a core update. Google reassesses, your rankings move, and there's no one to diagnose whether it's content quality, a technical regression or ordinary volatility. Recovering from an undiagnosed drop costs multiples of what monitoring would have.
The honest middle: a project, then something small
For a large number of Indian businesses, the right purchase isn't a permanent retainer and isn't a one-off package. It's a proper project followed by a light, defined maintenance arrangement.
The project buys the foundations: audit, architecture, redirects, schema, template rules, tracking, and a cornerstone set of pages that answer the questions your buyers actually ask. That's the ₹1,50,000–₹4,00,000 block, delivered over two to four months, and it's a genuinely one-time cost. A paid SEO audit that your developer can actually use is where that starts — the free ones are sales documents.
The maintenance arrangement then covers only what has to recur: monitoring, a defined number of content refreshes, and someone who reviews releases before they ship. That can be a fraction of a full retainer, and any agency unwilling to sell it is telling you what it optimises for.
The case for a full retainer is a competitive one. If a rival is publishing weekly, if you're launching into new categories, if your catalogue changes constantly, or if your product team deploys every fortnight, the work genuinely doesn't stop and pretending otherwise costs more than the fee. That's the situation we're built for: SEO from ₹75,000/mo, smaller sites from ₹40,000/mo, ex-GST, month-to-month after the first quarter and 30 days' notice. We freeze your trailing-90-day qualified organic leads on day one, and if we haven't beaten that number in 90 days we keep working free until we do. If your site is in one of the two categories above, we'll tell you to buy the project instead — it's a shorter conversation and a better outcome.
