How Much Does an SEO Agency Cost?
Last updated 11 August 2026
Guide
Between $1,500 and $10,000 a month, depending far less on the agency's size than on how much execution you're actually buying.
Most SEO agencies charge between $1,500 and $10,000 a month, with a handful of enterprise firms going higher. The real number depends less on the agency's size than on what you're paying for: strategy and reporting cost less, hands-on execution (content, links, technical fixes) costs more, and almost every agency contract starts with a 30 to 90 day period where you're paying full price for very little visible output.
The three pricing tiers you'll actually see in proposals
Agency pricing clusters into rough bands. These aren't official categories, just what shows up repeatedly across proposals and public rate cards.
- Freelancers and boutique consultants: $750 to $2,500/month — usually one person or a two-person shop. You get audits, keyword research, on-page recommendations and maybe a monthly call. Content writing and link building are often billed separately or excluded entirely. Good for a single-founder SaaS with a narrow niche and a small number of pages, less useful if you need volume.
- Mid-market agencies: $2,500 to $7,500/month — the most common bracket for funded startups. It typically includes technical audits, a content calendar with a handful of articles per month, some outreach-based link building and a dedicated account manager. The catch: many of these retainers quote “up to X hours” of work, and content production is the first thing that gets trimmed when the agency is over capacity.
- Full-service and enterprise agencies: $7,500 to $20,000+/month — these firms bundle SEO with paid media, CRO and sometimes PR. They come with case studies, bigger teams and slower decision cycles. For an early-stage startup this tier rarely makes sense financially: you're paying for account management overhead that a two-person marketing team doesn't need.
Across all three tiers, published rate surveys from agency directories like Clutch generally place average SEO retainers in the $2,500 to $5,000/month range for small and mid-size businesses in the US, with hourly consulting rates commonly falling between $100 and $300/hour. Your actual number will vary by market, but that middle band is a reasonable anchor if you're pricing out proposals.
What's included, and what costs extra
- Included by default — technical audits, keyword tracking, monthly reporting calls, basic on-page recommendations.
- Often billed as add-ons — content writing (frequently $150 to $500 per article on top of the retainer), link building campaigns, migrations, and international or multi-language SEO.
- Rarely included at all — paid link acquisition, digital PR outreach, and anything related to AI search visibility: being cited by ChatGPT, Perplexity or Google's AI Overviews. Most traditional SEO contracts were written before generative engines existed as a distribution channel, so this is usually absent unless you specifically ask.
That last gap matters more each year. If your buyers are increasingly asking AI assistants “what's the best tool for X” instead of typing a Google query, a contract that only covers classic ranking signals is covering less of your actual funnel than it used to.
The onboarding delay nobody puts in the proposal
Almost every SEO agency, regardless of tier, requires an onboarding period before meaningful work starts. This typically runs 30 to 60 days and covers account access, technical audits, competitor research and keyword strategy sign-off. During this window you're paying the full retainer for planning documents, not published content or links.
Add the standard 3 to 6 months it takes for new content and technical fixes to show measurable ranking movement, and a founder signing a 6-month SEO contract is often 3 to 4 months in before seeing any traffic impact. For a startup burning runway, that's a meaningful chunk of your budget spent before you know if the strategy works.
When hiring an agency actually makes sense
- You have a large site (500+ pages) with structural technical issues that need specialist audit work
- You're targeting a competitive, high-value keyword space where nuanced strategy genuinely beats volume
- You have the budget to absorb 60 to 90 days of near-zero visible output without panic
When it's usually the wrong call
- You're pre-product-market-fit and need to validate channels quickly, not commit to a 6-month contract
- Your content need is closer to “15 to 30 solid articles a month” than “a bespoke strategy deck”
- You need coverage across both classic SEO and AI citation (Reddit visibility, being referenced by ChatGPT and Claude), which most traditional agencies don't price or execute for at all
Cheaper alternatives at each budget level
If the retainer math doesn't work for your stage, there's a growing category of tools built to do the execution work an agency would otherwise bill hourly for: article generation, backlink building and audits, often for a flat monthly fee instead of a retainer plus add-ons. We break down that comparison, including where measurement-only tools like Semrush fit versus full execution platforms, in how much GEO costs.
Geograph is one example of this category: it runs Reddit monitoring, reply drafting, AI-optimised article publishing and weekly site audits from one $39/month plan, aimed specifically at getting cited by AI assistants and ranked on Google. For a solo founder deciding between a $2,500/month retainer and a self-serve tool, the honest comparison is scope: an agency brings strategic judgement and account management, a tool like Geograph brings continuous execution without the onboarding lag or per-article billing.
Frequently asked questions
- Is a $1,000/month SEO retainer worth it?
- At that price you're typically getting audits and recommendations, not execution. If you have the internal capacity to act on the recommendations yourself, it can work. If you need someone to actually write and publish content, budget more or look at execution-focused tools instead.
- Why do agencies require 6-month minimum contracts?
- SEO changes take weeks to months to show ranking movement, and agencies use the minimum term to avoid churn before results materialise. It's a reasonable ask in principle, but it also means you're locked in before you've seen any evidence the strategy is working.
- Do SEO agencies handle AI search visibility (GEO)?
- Some do. Traditional SEO retainers are built around Google ranking signals, not the specific structuring, source diversity and Reddit presence that gets a brand cited by AI assistants. If GEO matters to your funnel, ask explicitly what the agency does for it before signing.
- What's cheaper than an agency but more than a DIY approach?
- Execution-focused SaaS tools that generate content, monitor relevant conversations and build backlinks automatically, typically priced from $39/month up to a few hundred a month rather than $1,500+. We cover the full cost breakdown of DIY versus tools versus agencies in how much GEO costs.
