Do you need an SEO agency? The honest answer is: probably not yet.
SEO agencies are a real, legitimate service. Some of them are excellent. And for most vibe coders at the early stage, they are the wrong tool at the wrong time — not because agencies don't work, but because what you need right now is different from what agencies sell.
This page gives you a direct answer to the question, including the cases where an agency genuinely is the right call.
By Alexander Shoucair, co-founder of Chad AI — the vibe marketing execution layer.
The Make-or-Buy Test: how to decide honestly
The agency decision comes down to one question: what is the actual constraint?
If the constraint is time — you have budget, validated traction, and a clear content strategy, but not enough hours to execute — an agency can be the right answer.
If the constraint is knowledge — you don't know what to do yet — an agency will make decisions for you that you don't understand, can't evaluate, and can't build on when they're gone.
If the constraint is budget — you're pre-revenue or early-revenue — an agency's minimum viable engagement (typically £3–10k/month) makes no economic sense before you've validated that the channel works for your product.
Most vibe coders have a knowledge constraint and a budget constraint. An agency solves neither of those.
When an SEO agency IS the right call
There are real cases where hiring an agency makes sense. Be honest with yourself about whether you're in one:
You have validated traction and need to scale content.If you already know which queries convert, you're generating revenue, and you need 20 pieces of content per month to feed a proven funnel — an agency makes sense. You're buying execution, not strategy.
You're in a highly technical or regulated industry.Healthcare, legal, financial services — sectors where content requires genuine domain expertise and compliance review. Agency specialists in those verticals earn their fee.
You need local SEO across multiple locations. Multi-location businesses with complex local search needs (Google Business profiles, local citations, location-specific content at scale) are a genuine agency use case.
You have a strong in-house strategy function and need tactical support.If you know exactly what you want and need people to execute it under your direction, an agency can work. If you're hoping the agency will tell you what you want — that's a different purchase.
When an SEO agency is the wrong call
For most vibe coders, none of the above applies yet. Here's when to wait:
You haven't validated that the channel works for your product.Before spending £5k/month on an agency, spend 90 days proving that SEO-driven content converts visitors for your specific product. If it does, scale it. If it doesn't, you've saved yourself a six-month retainer.
You don't understand enough SEO to evaluate the agency's work.An agency that knows you can't evaluate their output has very little accountability. If you can't tell good SEO work from bad, you can't fire the bad agency until you've wasted months of budget.
Your site has basic technical problems that will constrain any agency's results.Missing title tags, no sitemap, schema errors, slow mobile load times — fix these yourself first. Paying an agency to fix things a tool or a developer can do in a weekend is expensive.
You need your first users, not scale. Agencies optimise at scale. They are not the right tool for getting your first 100 users. Community, direct outreach, and targeted content you write yourself gets you to 100 faster and cheaper.
What to do before you hire an agency
If you do eventually hire an agency, these steps make that engagement more likely to succeed — and they generate real results in the meantime:
- Fix your technical SEO floor: sitemap, title tags, meta descriptions, schema markup, Search Console setup
- Publish 3–5 targeted content pages and measure whether they convert
- Identify which queries your product should rank for and which are actually driving your best customers
- Document your brand voice, ideal customer, and competitive position so an agency doesn't have to guess
- Run your first AI visibility audit to understand your GEO position — most agencies don't do this and will leave the channel untouched
Do this work and you'll either find you don't need an agency, or you'll be a much better agency client.
The 5 mistakes vibe coders make when evaluating SEO agencies
Mistake 1: Evaluating by case studies from a different industry.
An agency that ranked an e-commerce site for product keywords faces completely different challenges from ranking a SaaS product for intent-based queries. Ask specifically for results in your vertical.
Mistake 2: Signing a long retainer before testing the relationship.
A good agency will agree to a 3-month trial engagement before asking you to commit to 12 months. If an agency insists on a long-term contract before proving results, that's a red flag.
Mistake 3: Choosing based on price.
The cheapest SEO agencies are cheap because they use tactics (link schemes, thin content, AI-generated articles at scale) that work briefly and then damage your domain. SEO done badly is worse than SEO not done at all.
Mistake 4: Not asking about GEO.
Most SEO agencies have no AI visibility practice. They optimise for Google and leave ChatGPT, Perplexity, and Claude citations untouched. In 2025, that is half the opportunity. Ask directly: what is your approach to generative engine optimisation?
Mistake 5: Expecting an agency to replace a strategy.
An agency executes. They shouldn't be setting your positioning, choosing your ICP, or deciding which product features to emphasise. If you don't have those answers, an agency will make them up — and you might not notice until six months in.
Your 90-day alternative to hiring an agency
Month 1: Technical floor and target query identification.
Free to implement. Builds the foundation an agency would charge you to audit.
Month 2: Publish 3 targeted content pages.
Measure conversion. Build the evidence base for what works before scaling anything.
Month 3: Add the GEO layer.
Schema, FAQ sections, AI visibility audit. The channel most agencies don't touch and the one with the lowest competition right now.
After month 3:
You now know whether SEO converts for your product, which queries work, and what your AI visibility looks like. You're a dramatically better agency client if you decide to hire one — and you may find you don't need to.
FAQ
How much do SEO agencies typically charge?
Monthly retainers typically range from £2,000 to £10,000+ depending on scope, market, and agency size. Project-based work can be scoped separately. For most early-stage vibe-coded products, the minimum viable agency engagement costs more than the product's monthly revenue.
What does an SEO agency actually do day-to-day?
Typically: keyword research, content briefs and writing, technical SEO audits and fixes, link building outreach, and monthly reporting. The ratio of strategy to execution varies significantly by agency.
Can I do SEO myself as a solo founder?
Yes — the foundational work is learnable and the tools to execute it are accessible. The honest constraint is time, not complexity. The technical floor, keyword research, and content creation for a focused cluster of 10–15 pages is achievable as a solo founder over 3–6 months.
What's the difference between an SEO agency and a content agency?
An SEO agency is primarily focused on search rankings: technical health, keyword targeting, and link authority. A content agency is primarily focused on producing written material. Many agencies do both, but it's worth asking which capability is their core strength.
Do agencies handle AI search (ChatGPT, Perplexity) as well as Google?
Most don't have a mature GEO practice yet. Traditional SEO agencies optimise for Google; generative AI visibility requires a different set of tactics. Ask specifically about GEO before assuming it's included.
How long before an SEO agency produces results?
Honest timeline: 4–6 months before meaningful ranking improvements, 6–12 months before material traffic growth for a new or low-authority domain. Agencies that promise results in 30–60 days are either using risky tactics or selling something other than organic SEO.
What should I ask an SEO agency before hiring?
Five essential questions: (1) Show me results for a product at a similar stage to mine. (2) What's your approach to GEO and AI visibility? (3) What does the first 90 days look like? (4) What are you NOT going to do? (5) What does success look like and how do we measure it?

Yes — AI-powered tools that execute the work for you without the agency overhead. Vibe marketing tools like Chad handle the audit, content creation, technical fixes, and GEO optimisation in a single conversation, at a fraction of agency cost.
