How Much Does SEO Cost?

How Much Does SEO Cost per Month?

Most SEO is sold as a monthly retainer, and the surveys that publish their method put the typical retainer between a few hundred and a couple of thousand dollars a month, with providers in the US and Canada charging more than those in Europe.¹ SE Ranking’s survey of 260 agencies, published in December 2024, found the most common range was $500 to $1,000 a month, and 64% of agencies charged below $1,000.¹

Read these figures with three limits in mind. SE Ranking sells software to SEO agencies and says its own samples are too small for statistical significance, and nearly all the agencies it surveyed serve small or local businesses.¹ Ahrefs doesn’t say when it ran its poll, and some figures on its page disagree with each other, so we’ve used only its two most basic findings.³ None of these surveys describes what a company with hundreds of pages, several locations or a national market is quoted, and we haven’t found a published survey that does, so treat the ranges as a guide to the small-business market rather than a price list.

Why Do SEO Quotes Vary So Much?

SEO quotes vary because they price different amounts of work for different markets: how much technical repair, content and link-building the plan includes, how hard the searches are to win, how big the site is, and how large and where the provider is. Two quotes for “SEO” can describe jobs that have little in common.

• The pricing model. A monthly retainer pays for ongoing work, a project fee pays for a defined job such as an audit or a site migration, and an hourly rate pays for advice or fixes your team carries out. Many agencies offer more than one, and SE Ranking found 53% prefer the retainer.¹
• The scope. Technical work fixes how search engines crawl and read the site; content work writes pages that answer what buyers search for; link-building earns mentions and links from other sites. Ask who writes the content, because pages that win buyers take writers who understand what those buyers need.
• The competition. Ranking for searches that national companies and well-funded competitors already own takes more content and more time than ranking for a local service search with few strong pages.
• The size of the site. A site with thousands of product pages needs more technical work than a twenty-page service site, and moving to a new site without mapping every old page to its new address can lose search traffic the business already had, which is something we’ve seen in client work.
• Who does the work. Larger agencies charge more, and in SE Ranking’s survey over 70% of agencies with 25 or more employees charged over $1,000 a month.¹

When you compare quotes, put them on the same footing first: what work each includes every month, which searches it targets, and who on the provider’s side writes the content, and before any of that, decide whether SEO belongs in your channel plan yet, which the Channel Selection page helps you work out.

Is It Worth Paying for SEO?

Paying for SEO is worth it when the customers it wins on searches that bring buyers cost you less than those customers are worth, judged over long enough for the work to compound. Rankings and traffic tell you whether the work is happening, while customers tell you whether it’s paying back.

To judge a quote before you sign:

1. List the searches that already bring you customers, from paid search and from your own sales records, so you know which terms are worth ranking for.
2. Work out what a new customer is worth to you, and the most you can afford to spend to win one, which depends on how long customers stay, how early their profit arrives and how much cash you have to wait.
3. Divide a year of the quoted fee by that amount to find how many extra customers a year the work has to bring to pay its way.
4. Ask the provider which of your proven searches it will target and what it expects to happen on them, and in what timeframe, a question Google itself suggests asking,⁴ and how to choose an SEO agency lists the others worth putting to every provider.
5. Agree how you’ll count the customers, in your CRM or by asking every new customer how they found you, rather than by rankings or visits.

In its first year, SEO usually looks more expensive per customer than paid search, because you’re paying for pages before they rank. The case for it is that the pages keep bringing customers after they rank, so judge it over a longer period than you’d give an ad campaign, and judge it against your ceiling instead of against paid search’s first-year numbers. Our page on whether Google Ads are worth it uses the same test for paid search, and how to forecast SEO shows how to estimate what your proven searches could bring.

How Long Does SEO Take to Work?

SEO usually takes months to show results in customers, because new pages have to be found, ranked and trusted before they bring steady visits, while paid search can send visitors as soon as the ads go live. That gap is why we put paid search first and SEO second.

Paid search shows within a sales cycle or two which searches bring buyers and which pages turn them into leads, and then SEO investment goes behind those proven terms, so the two support each other instead of competing for the same budget. In accounts we manage, the paid search data usually shows which keywords produce revenue, and that list is where SEO money does the most good. Which shows results more quickly, SEO or search advertising covers when that order changes, and the Channel Selection page explains how this fits into choosing channels.

Leaders often compare a monthly marketing fee to a salesperson’s salary and want to know when it will start to earn its keep, which is a fair question for any provider to answer in writing. Google warns that anyone who guarantees you first place in search results should be passed over, and we agree, because no provider controls the rankings.⁴ A good answer names the searches, the work and the point at which you’ll both look at customers won.

When Is SEO Not Worth It Yet?

SEO isn’t worth paying for yet when your website doesn’t turn visitors into leads, when you don’t know which searches bring buyers, when hardly anyone searches for what you sell, or when cash flow can’t wait months for a return. In each of those cases, the money does more good somewhere else first.

We sell SEO, so weigh what follows with that in mind, but we’d still tell you to wait:

• When the website doesn’t convert. SEO brings visitors to your pages, and if those pages don’t turn visitors into leads, more traffic only makes the leak bigger, so fix the pages first.
• When you haven’t proven which searches bring buyers. Without paid search data or sales records to point to, SEO spends months chasing terms that may bring readers rather than customers.
• When buyers don’t search for what you sell. If your category is new or your buyers don’t know they have the problem yet, channels that reach people before they start looking will work sooner.
• When the business can’t wait. If you need customers this quarter, paid search and direct outreach to named accounts will bring them faster, and SEO can follow once cash allows.
• When the quote promises rankings instead of customers. A plan built around guaranteed positions or a count of links, with no view on which searches bring buyers, is selling activity rather than customers.

If the honest answer is that you aren’t ready, the cheaper first step is to work out what you can afford to pay for a customer, which our page on how much a company should spend on marketing walks through.
