SEO for a US service business typically runs $1,000–$5,000 per month (WebFX), and the average agency retainer is $3,209/month per Ahrefs' 439-provider survey. Foundgrove's own retainers start at $2,500/month, month-to-month with no lock-in. Use the calculator below to estimate your monthly range by industry, service area, and site condition.

Methodology
How this calculator works
The calculator applies Foundgrove's published pricing model to your three inputs — nothing is estimated from hidden market math. Retainers start at $2,500/month on the Growth tier and scale to $10,000+/month for competitive verticals or multi-location operations; those two published anchors set the bottom and top bands. Service area moves you between bands because scope drives content volume and local-signal work. Industry shifts the band up one step when the vertical's customer-acquisition costs are measurably higher — law, dental, and med spa clicks cost $68.89–$199.39 each in the chart below, and SEO competition tracks what the clicks are worth.
The estimate is deliberately a range, not a number. A real quote depends on your site's condition and your market — which is why the honest next step is a free teardown of your actual site rather than a bigger form. For the full narrative of what drives SEO pricing — hidden costs, ROI math, and tier-by-tier detail — read our complete guide to what SEO costs a service business.
The model, in the open
What the calculator will tell you
The full band table the calculator draws from — service area sets the row, and a competitive vertical (law, dental, med spa) moves you one row down:
| Service area | Standard vertical | Competitive vertical |
|---|---|---|
| One city or metro | $2,500–$3,500/mo | $3,000–$5,000/mo |
| Several cities | $3,000–$5,000/mo | $4,000–$7,500/mo |
| Statewide | $4,000–$7,500/mo | $5,000–$10,000/mo |
| Multi-state or national | $5,000–$10,000/mo | $5,000–$10,000+/mo |
A site that needs rebuilding adds $8,500–$25,000 one-time — Foundgrove's published fixed-fee range for a conversion-focused build — because SEO spend on a site that can't convert wastes part of every month's retainer.
Benchmarks
What does SEO cost per month in 2026?
Monthly retainers are the dominant model — 78.2% of SEOs charge one, per Ahrefs' survey of 439 SEO providers. What that retainer costs varies by who you hire and where they are:
| Benchmark | Figure | Source |
|---|---|---|
| Average agency retainer | $3,209/mo | Ahrefs, 439 providers |
| Average retainer, all provider types | $2,917/mo | Ahrefs |
| Most common engagement band | $1,000–$2,500/mo | Backlinko, 300+ pros (Dec 2025) |
| Small-business range | $1,500–$3,500/mo | WebFX |
| Most common hourly rate | $75–$100/hr | Ahrefs |
| North America vs Europe, retainers over $2,000/mo | 22% vs 9% | SE Ranking, 260 agencies |
| Foundgrove retainer | from $2,500/mo | Published pricing |
"SEO costs usually range from $250 to $10,000 per month, with most businesses (63%) spending between $500 and $5,000."
Two caveats worth knowing: US-based services cost 3–5x more than providers in emerging markets (Backlinko), and SE Ranking's authors note their 260-agency sample may not reach statistical significance — treat every survey band as a range, not a rule.
Comparison
Published agency rates, compared
Survey averages hide a practical problem: most agencies never print a number. We checked the rate pages agencies actually publish (all fetched August 2026) — and SE Ranking's survey explains why retainers dominate the cards that do exist: "53% of survey participants prefer monthly retainers over all other pricing models" (Svitlana Shchehel, SE Ranking).
| Agency | Published rate | Commitment | Where published |
|---|---|---|---|
| Straight North | from $1,500/mo; most clients $4,000–$8,000/mo | not stated | own pricing page |
| Coalition Technologies | $1,500–$3,100/mo typical, by campaign type | not stated | own pricing page |
| Foundgrove | from $2,500/mo | month-to-month, no setup fee | own pricing page |
| WebFX | from $3,000/mo | 6-month initial commitment | own services page |
| Victorious | $4,999 / $8,999 / $11,999/mo | not stated | G2, provider-supplied |
| Loganix | $500/mo or $1,000/mo + $500 setup (link-building-led packages) | no minimum term | own packages page |
Worth knowing before you compare: two of the highest-ranking "SEO cost" guides — HigherVisibility's and OuterBox's — publish only industry survey averages on those pages, not their own rates (both fetched August 2026), and Victorious' on-site pricing page was offline when we checked, leaving its G2-listed tiers as the published record. A rate card you can read before the sales call is itself a signal of how an agency treats scope.
Hourly
How much does SEO cost per hour?
$75–$100 per hour is the most common SEO rate — 24% of providers land there — and the overall average is $111/hour, with 1 in 10 charging more than $150 (Ahrefs, 439 providers). Experience moves the number more than anything else: Backlinko's survey places entry practitioners at $50–$100/hour, senior specialists at $101–$150, and experts at $151–$200+, with rates climbing roughly $15–$25/hour per experience step for the first decade.
Hourly billing suits diagnosis, not delivery: a technical audit, a migration consult, a one-off fix. A full ranking program bought by the hour turns every month into a negotiation — which is why 78.2% of the market bills retainers instead. The seniority effect is not anecdote: "Our data shows a near-linear relationship between years of experience and hourly rates" (Backlinko).
Project
How much does project-based SEO cost?
$2,501–$5,000 is the most common one-off project band — 21.2% of providers price there (Ahrefs) — though the market's cheap end is wide: SE Ranking's 260-agency survey found 66% of project fees land between $500 and $2,000, and only 18% above $3,000. WebFX frames the same spread as $500–$5,000 per project.
The scope is what you are buying: a defined deliverable — an audit with a fix roadmap, a migration, a content build — with a start and an end. Work that has no end (rankings, links, AI citations) does not fit a project fee, which is the boundary between this table and the retainer bands above it.
Who you hire
How do provider type and business size change the number?
The same scope costs different money from different desks. Freelancers average $1,348.63/month against an agency average of $3,209/month (Ahrefs), and US-based services run 3–5x the price of providers in emerging markets (Backlinko) — a gap that buys accountability, native-market judgment, and seniority, or buys nothing, depending on the desk. Business size sets the other axis: WebFX's published ranges run $500–$1,500/month for a micro business, $1,500–$3,500 for a small business, $1,500–$10,000 mid-market, and $10,000–$50,000+ at enterprise scale.
Build or buy
What about hiring in-house instead?
An in-house SEO specialist averages $67,388–$80,670 a year in the US (ZipRecruiter, Aug 2026 / Indeed, 888 posted salaries), and an SEO manager $86,206–$89,098 — that is $5,600–$6,700 a month in specialist salary alone, before benefits and tools (the BLS puts private-industry total compensation at $46.60/hour against $32.60/hour in wages). One hire also buys one skill set, where a program needs several: technical, content, links, local.
The full build-or-buy decision — including when in-house genuinely wins — is its own comparison: in-house SEO vs agency vs freelancer. For cost purposes the short version is: below roughly the cost of half a hire, an agency or senior freelancer is the only way to get the full skill stack.
Original data
How much does SEO cost by industry?
Industry moves the price because customer-acquisition costs differ by vertical — you can read it directly off what one Google Ads click costs on each industry's agency keywords (our DataForSEO pull, August 2026, vendor data). Here is each vertical's measured click cost next to where its calculator estimate starts for a single metro:
| Industry | Measured click cost | Single-metro band | Our program |
|---|---|---|---|
| Law firms | $199.39 | $3,000–$5,000/mo | SEO for law firms |
| Plumbing | $111.78 | $2,500–$3,500/mo | SEO for plumbing companies |
| HVAC | $91.17 | $2,500–$3,500/mo | SEO for HVAC companies |
| Dental | $68.89 | $3,000–$5,000/mo | SEO for dental practices |
| Roofing | $32.32 | $2,500–$3,500/mo | SEO for roofers |
| Med spa / aesthetics | — | $3,000–$5,000/mo | SEO for med spas |
Click costs are the current Google Ads average CPC on each vertical's "[industry] SEO agency/company" keyword (DataForSEO, retrieved August 2026); the med spa keyword returned no CPC in our pull, so none is shown. Bands are the calculator's single-metro starting rows, not quotes.
Original data
Why SEO clicks cost what they do
SEO pricing tracks what the clicks are worth. We pulled the current Google Ads cost-per-click on the exact keywords service businesses type when they shop for SEO help (DataForSEO keyword database, retrieved August 2026 — a vendor dataset, not a Google figure). One law-firm click costs more than most agencies charge for an hour:
For context, the median CPC across all industries' consumer-side search ads is $5.42 (LocaliQ, 13,474 US campaigns, 2025–2026). The agency keywords above run 6–37x that, and the average search-ads cost per lead across industries is $66.69 (LocaliQ). That is the arithmetic behind every retainer: at HVAC's $91.17 per click, a $2,500 monthly budget buys roughly 27 paid clicks that stop the day you stop paying — the same budget in an SEO retainer funds pages, links, and local signals you own permanently.
Same budget, two channels
SEO vs PPC: what the same $2,500 buys
Put the Growth-tier retainer next to the same spend in Google Ads at each vertical's measured click cost (simple division — budget ÷ CPC from the chart above):
| Vertical | Measured CPC | ≈ clicks from $2,500 in ads | $2,500 in the retainer |
|---|---|---|---|
| Law firms | $199.39 | ≈ 12 | A month of owned assets: pages, earned links, local signals, and AI-answer coverage that keep working after the spend stops |
| HVAC | $91.17 | ≈ 27 | |
| Roofing | $32.32 | ≈ 77 |
This is a cost comparison, not a verdict — paid search is the faster channel and the right first move in some situations. Which channel deserves the first dollar, and when to run both, is the decision we work through in SEO vs Google Ads: which should a service business fund first?
Tiers
SEO pricing packages: what changes as the price goes up
Packages differ less in what they list and more in execution volume. Reading any agency's tiers — including Foundgrove's published tiers — what moves with price is:
- Content volume — how many pages and articles ship per month, and whether they are written by industry-experienced writers or templated.
- Link acquisition — whether earned links are included at all; this is the single most common gap in sub-$1,000 packages.
- Scope of surfaces — classic rankings only, or also Google Business Profile, AI Overviews, and answer-engine citations.
- Who does the work — a senior strategist or a junior account layer; agencies charge 138% more than freelancers on average (Ahrefs), and part of that gap is real seniority.
Buyer protection
Red flags in SEO pricing
The pricing itself tells you how an engagement will go. Five patterns to walk away from:
- A guaranteed ranking attached to a price. Nobody controls Google; a guarantee is a sales device, not a deliverable.
- A long lock-in with vague monthly scope. The compared rate cards above show month-to-month exists at every price point — a 12-month contract with undefined deliverables shifts all the risk to you.
- The agency keeps your assets. If content, the site, or the Google Business Profile stays theirs when you leave, the retainer was rent, not investment.
- Reporting that stops at rankings. A report that never reaches calls, forms, and booked work is priced against the wrong outcome.
- A price with no scope attached — in either direction. Backlinko's own red-flag list includes unusually cheap pricing relative to other quotes (Backlinko); a number that can't explain what ships each month is a red flag at $500 and at $5,000.
AI search
How much does GEO / AI-search optimization cost?
Standalone AI-visibility optimization — getting recommended by AI Overviews, ChatGPT, and Perplexity — averages $937/month as a separate service (SE Ranking's agency survey). It is the newest line on agency rate cards, and the pricing is still settling: most agencies either fold it into an SEO retainer or sell it as an add-on.
Foundgrove takes the first path — GEO and AEO are part of the $2,500/month retainer, because the work shares its foundations with SEO. For businesses whose priority is specifically AI citations, the dedicated generative engine optimization service runs it as its own program with AI-visibility tracking.
Local
How much does local SEO cost?
Local SEO averages $1,557/month (Ahrefs) — the least expensive professional tier, because the battleground is one metro's map pack rather than a national SERP. If your business serves a single service area, that is the spend that moves first: Google Business Profile categories and services, review velocity, citation consistency, and pages for the towns you actually serve.
At Foundgrove, local SEO is not sold separately — GBP optimization, citation cleanup, and local content are part of every service-area retainer, which is why the calculator's single-metro band starts at the retainer floor rather than adding a local surcharge.
Answers
SEO Cost FAQ (2026)
How much does SEO cost per month in 2026?
Across surveys: the average retainer is $2,917/month overall and $3,209/month for agencies (Ahrefs, 439 providers), most engagements land in the $1,000–$2,500/month band (Backlinko, 300+ professionals, Dec 2025), and WebFX places small businesses at $1,500–$3,500/month. Foundgrove's retainer starts at $2,500/month, month-to-month.
Why do SEO agencies charge $2,500 or more per month?
Because the alternative is buying every click. On the agency keywords we measured (DataForSEO, Aug 2026), one Google Ads click costs $32.32–$199.39 depending on vertical — at HVAC's $91.17 average, $2,500 buys roughly 27 clicks and stops the day you stop paying, while an SEO retainer funds pages, links, and local signals you keep.
Is $500-per-month SEO worth it?
Cheap retainers exist — SE Ranking's 260-agency survey found 64% of agencies charge under $1,000/month (the authors note the sample is small), and 30% charge under $500. The question is what ships at that price. Most sub-$1,000 engagements are audit-report subscriptions, not execution. We break down what cheap SEO actually includes in our guide below.
How much does local SEO cost?
Ahrefs' survey puts local SEO at $1,557/month on average — the cheapest tier of professional SEO because the surface is one metro's map pack and local queries. At Foundgrove, local SEO is not a separate product: Google Business Profile work, citations, and local content are included in every service-area retainer.
How much does SEO cost per hour?
$75–$100/hour is the most common bracket and $111/hour the average across Ahrefs' 439-provider survey; Backlinko's experience tiers run $50–$100 overall, $101–$150 for senior specialists, and $151–$200+ at expert level. Hourly fits audits and one-off fixes — a full program priced hourly becomes unbudgetable.
How much does a one-off SEO project cost?
$2,501–$5,000 is the most common project band (21.2% of providers, Ahrefs), while SE Ranking's 260-agency survey finds 66% of project fees land between $500 and $2,000. Scope sets the price: audits, migrations, and defined content builds fit a project fee; ongoing ranking work does not.
How much does GEO or AI-search optimization cost?
Standalone AI-visibility (AIO) optimization services average $937/month per SE Ranking's agency survey. At Foundgrove, GEO and AEO are included in the $2,500/month retainer rather than sold separately, with a dedicated GEO service for AI-citation-first engagements.
Do SEO agencies publish their prices?
Mostly no. Of the cost guides ranking for this query, several — HigherVisibility and OuterBox among them — publish only industry survey averages, not their own rates (checked August 2026). Agencies that do publish range from Loganix's $500/month packages to Victorious' $11,999/month enterprise tier on G2; Foundgrove publishes all three of its tiers openly on its pricing page.
Is this calculator's estimate a quote?
No. The estimate applies Foundgrove's published pricing model — retainers from $2,500/month scaling to $10,000+/month for competitive verticals or multi-location operations, plus $8,500–$25,000 one-time for a site rebuild — to your three inputs. A real number needs a look at your actual site, which is what the free audit is for.
