Hiring an SEO comes down to three things: proof of past results, a clear explanation of what they’ll actually do to your site, and a contract you can walk away from without penalty. Skip any agency that can’t produce all three. That’s the short version. The rest of this covers how to verify each one, what red flags look like in practice, and what a fair engagement actually costs. Agencies like Peak Marketing get asked this question constantly, because most business owners have been burned once already by someone who promised rankings and delivered a spreadsheet of keywords nobody searches for.
Start With Proof, Not Promises
Ask for three client examples in your industry or a similar one. A legitimate SEO firm will show you organic traffic graphs, ranking changes for specific terms, and ideally a client reference you can call directly. If an agency hedges here, or only shows you screenshots of a dashboard with no context, that’s your answer.
Pay attention to how they describe the results. “We got them to page one” means nothing without knowing which keyword, how much monthly search volume it has, and whether that traffic converted into leads or sales. Rankings without revenue are a vanity metric.
Understand What You’re Actually Buying
SEO isn’t one service. It’s usually some combination of technical fixes, content creation, and link building, and the mix should match your site’s actual problems.
- A site with solid content but slow load times and broken schema markup needs technical work first.
- A site with clean code but thin, generic pages needs content.
- A site with good content and decent technical health but no external links pointing to it needs link building.
Ask the agency to audit your site before quoting a price. If they skip straight to a monthly retainer number without looking at your site, they’re selling a package, not a strategy.
Watch for These Red Flags
A few patterns show up again and again with agencies that underdeliver.
Guaranteed rankings are the biggest one. No one controls Google’s algorithm, and any contract promising a specific position for a specific keyword by a specific date is either uninformed or dishonest. Real SEO firms talk in terms of traffic trends and ranking improvements over a realistic timeline, not guarantees.
Vague reporting is another. If monthly reports are just a list of keyword positions with no explanation of what changed or why, you’re paying for busywork. A good report ties activity to outcomes: this page was rewritten, here’s how its traffic moved over the following eight weeks.
Long lock-in contracts without an exit clause are worth questioning too. SEO takes time to show results, generally three to six months before meaningful movement, but a twelve-month contract with no off-ramp puts all the risk on you if the relationship isn’t working.
What Fair Pricing Looks Like
Small business SEO retainers typically run from a few hundred dollars a month for narrow, local-focused work up to several thousand for competitive national markets. One-off audits or strategy engagements are priced separately and usually cost less than a full retainer.
The number that matters more than the sticker price is what’s included. A $500 monthly retainer that only includes automated keyword tracking is a worse deal than a $1,500 retainer that includes content production, technical audits, and a dedicated point of contact who answers questions the same week you ask them.
Get the deliverables in writing before you sign anything. Hours of work, number of pages produced, technical items addressed, and reporting frequency should all be spelled out, not left as “ongoing optimization.”
Questions to Ask Before Signing
These come up in almost every serious vetting conversation, and the answers tell you more than any sales pitch:
- Which of your current clients have been with you longer than a year, and can I talk to one?
- What’s your process when a client’s rankings drop after an update?
- Do you build links through outreach and relationships, or do you buy them in bulk?
- Who on your team will actually be working on my account?
An agency that answers these directly, without deflecting to marketing language, has probably done this enough times to know what works and what doesn’t.
The Bottom Line
Hiring an SEO is a vetting process, not a shopping decision. Look at proof before pricing, understand what mix of services your site actually needs, and avoid anyone selling guarantees or locking you into a contract with no way out. Agencies that have done this work for years, Peak Marketing included, tend to welcome this level of scrutiny because it’s how they land clients who stick around. If you’re evaluating options right now, ask for the audit first and the contract second. That order tells you a lot about who you’re about to work with.
