How to set an SEO budget

Start from 2–5% of revenue for B2B or 5–10% for B2C, then adjust for customer value and market competition. A step-by-step way to land on a real number.

Start from 2–5% of revenue for a B2B business or 5–10% for a B2C one as your total marketing budget, then size an SEO line inside it based on customer value, market competition, and how fast you need results. Adjust from there with real numbers, not the percentage alone.

The SEO pricing guide shows what that budget actually buys at each price point once you have landed on a number. This post is the arithmetic that gets you there.

What's a reasonable starting point for an SEO budget?

A percentage of revenue, as a starting range rather than a fixed answer. Guidance on overall marketing budgets — the wider category SEO sits inside — puts B2B companies at roughly 2–5% of revenue and B2C companies at 5–10% [1]. Treat that as the total marketing line, with SEO claiming a meaningful slice of it rather than the whole thing.

5–10% of revenue

what one marketing-budget guide puts B2C companies at, against 2–5% for B2B — a starting range to size an SEO line inside, not a target on its own BDC, how much should you spend on marketing, checked 23 Sep 2026

Why the B2C number runs higher is mostly about deal size and repeat purchase behaviour: B2C marketing usually has to win a much larger number of smaller decisions, which costs more in aggregate even when each decision is cheaper to influence. B2B's lower percentage reflects fewer, larger deals where a smaller number of well-targeted efforts can move the needle.

Treat both ends of that range as a starting point to sanity-check against, not a formula to apply mechanically. A business with unusually high margins can afford to sit above its category's typical percentage and still turn a healthy profit; a low-margin business needs to be more conservative even if the percentage guideline says it can spend more. The percentage tells you roughly where other businesses like yours land, not where yours specifically should.

It is also worth separating "marketing budget" from "SEO budget" explicitly before you go further, because the two numbers get conflated more often than they should. Marketing covers everything from paid social to events to your website's design; SEO is one line inside that total, alongside content, technical work and outreach. Sizing SEO as a fraction of total marketing, rather than as a fraction of revenue directly, keeps the number honest about what else the business is already funding.

How do you turn a percentage into an actual SEO dollar figure?

By working out from your total marketing budget to the SEO line specifically, then checking that line against what SEO actually costs to execute well.

  1. Calculate your total marketing budget

    Multiply annual revenue by your target percentage — 2–5% for B2B, 5–10% for B2C — to get a full-year marketing number.

  2. Decide SEO's share of that total

    For most businesses without an established paid-search programme, 20–40% of total marketing budget going to SEO is a reasonable starting split.

  3. Divide by twelve for a monthly figure

    This gives you a monthly number to compare against published retainer benchmarks before you commit to it.

  4. Check the floor

    If the monthly figure lands under roughly $1,000, either raise the percentage or accept a narrower scope — monitoring and a few fixes, not a growth programme.

A $2 million-revenue B2B company at 3% of revenue has a $60,000 annual marketing budget. At 30% of that going to SEO, the SEO line is $18,000 a year, or $1,500 a month — comfortably inside the entry-to-mid retainer range published elsewhere [2][3].

If that number still feels tight against what you want to achieve, resist the temptation to close the gap with a pay-per-ranking deal instead of a properly funded flat retainer. Performance-based SEO almost always costs more per result once the arithmetic is run honestly, precisely because it is pitched to people whose budget feels too small — a smaller, honestly scoped retainer beats a larger, unpredictable performance deal in nearly every case.

How should customer value change that number?

More than almost anything else. Two businesses with identical revenue can justify wildly different SEO budgets once you account for what a single new customer is actually worth.

A business where one new customer is worth $10,000 in lifetime value can justify a much larger SEO spend relative to its revenue than a business where a customer is worth $50, because the payback math clears so much more easily. Work this out before locking in a percentage: take gross margin per sale, multiply by how many times a typical customer buys, and use that number — not the percentage-of-revenue guideline — as the real ceiling test for what you can afford to spend.

Run a simple version of that math before you commit to any number. If a realistic organic traffic gain would produce, say, fifteen extra customers a year worth $2,000 each in gross margin, that is $30,000 a year of value the programme has to be worth less than to be worth doing at all. A $1,500-a-month retainer — $18,000 a year — clears that bar comfortably. A $5,000-a-month retainer, at $60,000 a year, does not, however healthy the percentage-of-revenue guideline says it should be. The customer-value math should always be allowed to override the percentage, in either direction.

This is also where company size stops being a reliable guide on its own. A small company with an unusually high-value customer can justify a budget that looks large next to its revenue; a large company selling something cheap can be over-spending on a budget that looks modest by the same percentage measure. Revenue sets the ceiling on what you can afford; customer value sets the ceiling on what is worth affording.

How much should you budget in a competitive market?

More, and the extra money buys more attempts at the same terms rather than a higher hourly rate for the same work. A thin market with little competition can move on a modest budget because there is little standing in the way; a crowded market needs enough budget to out-produce and out-pitch everyone already ranking.

How market competition should move your monthly SEO budget
MarketWhat it looks likeReasonable monthly range
ThinFew competitors publishing content or earning links regularly$1,000–$2,500
ModerateSome active competitors, room to out-produce them$2,500–$5,000
CrowdedSeveral funded, actively publishing competitors$5,000–$10,000
Very crowdedNational or category leaders already dominating the terms$10,000 and up

Before trusting your own instinct about how competitive your market is, search the terms you actually want to rank for and look at who is already there. That list, more than any industry label, is what your budget has to beat.

Count specifically how many of the results are funded companies actively publishing new content, not just how many results exist. Ten results with mostly outdated pages and no clear publishing cadence describe a thinner market than the raw competitor count suggests, and five aggressive, well-resourced competitors describe a harder one than a quick glance would imply. Budget against that closer read, not the surface-level count.

Should the SEO budget include paid search, or sit separately?

Sit separately, even when one person manages both channels day to day. SEO and PPC pay back on different timelines and fail in different ways — a slow month of SEO looks nothing like a slow month of PPC — and merging the two budgets into one "search marketing" line makes it hard to tell which one is actually underperforming when results disappoint.

SEO vs PPC ROI covers how the two channels compare on cost and payback in more depth, including how much of your total budget should lean toward each one depending on how fast you need results. Keep the SEO line legible on its own, and compare it against the PPC line only at the level of total marketing return, not inside a single merged number.

How do you know if the budget you set is actually working?

By checking shipped output against the number, not just the number against a benchmark. A budget can be correctly sized and still fail because the work behind it never shipped — pages promised but not written, fixes listed but not deployed.

Once you have a budget number and a shortlist of providers, how to compare SEO quotes has a checklist for making sure two proposals at that price are actually offering the same thing.

Questions people also ask

  • What percentage of revenue should I budget for SEO?

    A reasonable starting range, drawn from broader marketing-budget guidance, is 2–5% of revenue for a B2B business and 5–10% for a B2C one, with SEO taking a meaningful share of that total marketing line rather than all of it.

  • Is there a minimum SEO budget worth spending?

    Roughly $1,000 to $1,500 a month is the point where a programme can fund one person actually making something — writing, fixing, or reaching out — rather than only monitoring. Below that, most of the fee goes to a dashboard, not to work.

  • How do I budget for SEO with no revenue history yet?

    Model it from a competitor's likely spend and your own funding runway rather than a percentage of nothing. Expect to fund at least two quarters before judging execution, since SEO on a brand-new domain starts from zero trust with search engines.

  • Should the SEO budget include paid search too?

    Keep them as separate lines even if one person manages both. SEO and PPC have different payback timelines and different failure modes, and merging the budgets makes it hard to tell which channel is actually underperforming.

  • How often should I revisit my SEO budget?

    At least once a year, and sooner if your market gets more competitive or your average customer value changes meaningfully. A budget set correctly at launch can be the wrong number eighteen months later if nobody checks it.
