How to Choose an SEO Agency When You Sell Technology

How to choose an SEO agency? Make each firm prove three things before you pay it: what ships in 90 days, who writes your pages, and who owns your accounts. A guaranteed ranking means walk away.

Pitches are easy. Delivery is where SEO gets hard, and a pitch is the one thing in the whole process that tells you nothing about delivery (I’d say the same about ours, for what that’s worth).

Suppose you run a 25-person managed IT shop and sign twelve months of SEO in January. The agency asks for logins and you hand them over, because it asked nicely. February’s report shows impressions up. March’s shows them up again. Then in June somebody wants to know how many of the quarter’s sales calls came from the website, and there’s no number, since nobody ever set up the tracking that would produce one. That’s a hypothetical, and the contract still has six months to run.

Who’s at fault? Everybody, a little. The owner never wrote down the job. The agency never asked what the job was. All of it was knowable in January, and that’s the point, because selection is the step where you can still fix this cheaply.

My bias, so you can factor it in. C4 sells SEO, AEO and GEO to tech companies. We aren’t an agency, we’re an operator-led growth partner, and we expect to be put through every test below.

Before You Choose an SEO Agency, Write Down the Job

Google publishes its own page for this decision, Do you need an SEO?, last updated in June 2026. It lists what agencies and consultants sell: a review of your content or structure, technical advice on hosting, redirects, error pages and JavaScript, content development, campaign management, keyword research, training, market expertise, and optimizing for generative AI. That’s a menu, and a long one. Shop from it and you can end up paying for keyword research when the real problem is a site that tells Google to skip half of its own pages.

So write the job first, on one page. Which services do you want search to sell? To which buyers? What’s broken today, if you even know? Who on your side approves copy, and how fast? What can you spend? If you can’t fill the page, you aren’t ready to compare agencies. You’re ready for a small audit.

Google also says a small local business can probably do much of this itself, and it points to its SEO starter guide as a practical read that describes much of what an SEO will do for you. A tech company with a long sales cycle usually has less time than it thinks. Read the guide anyway. An afternoon with it means every pitch has to survive a buyer who knows the basics.

One more point from that page. A great time to hire is during a site redesign or a new launch, the earlier the better, so the site gets built to be found from the start. Hiring after launch works too, since Google says a good SEO can improve an existing site.

Questions to Ask an SEO Agency, and What a Good Answer Sounds Like

Google gives you an interview list, and it beats the checklists agencies publish about themselves. Ask for examples of previous work and success stories. Ask whether they follow Google Search Essentials. Ask what results they expect, and in what timeframe. Ask how they measure success, what they know about your industry, how they’ll communicate, and whether they’ll share every change they make with the reasoning behind it. Simple enough.

Use all of it. Then add the questions a technology seller needs, because Google’s list was written for every website on earth. Yours is narrower.

Google adds a test I like. See if the SEO is interested in you. A good one asks what makes your business different, who your competitors are, how search can help and how your customers find you. If the first call is all slides and no questions, you’ve met the pitch. You haven’t met the work.

SEO Agency Red Flags Google Spells Out

Google’s page doubles as a warning label, and the list is specific.

• A guaranteed ranking, a “special relationship” with Google, or a “priority submit.” Google names all three.
• Secrecy. Be careful, Google says, if a company won’t clearly explain what it intends to do.
• An email out of the blue from someone who “noticed” your site. Google gets those too, and compares them to diet-pill spam.
• Links for sale. Google’s spam policies list buying or selling links for ranking purposes as link spam, and the page says you should never have to link to your SEO.
• A tool called “approved” by Google. Google says it doesn’t evaluate or endorse third-party SEO tools.

Five tells, all from Google.

Why does Google bother? Because the liability lands on you. The page says, “Ultimately, you are responsible for the actions of any companies you hire,” and warns that deceptive or misleading content created on your behalf could get your site removed from Google’s index, which turns an agency’s bad idea into your ranking problem. Nobody refunds that.

Now the newer pitch. Plenty of firms sell AI search as a separate product with its own secret method. Google’s page on AI features and your website says there are “no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary,” and that the usual SEO fundamentals still apply. Its hiring page even gives you the test: if an agency offers AEO or GEO services, ask whether the advice matches Google’s official guidance on generative AI features.

That doesn’t make AEO nonsense. It means the work is the old fundamentals done well, plus pages that answer the buyer’s question in the first sentence, and that second part is my view, not Google’s. A pitch built on a hidden trick is selling something Google says doesn’t exist. We covered where those pitches go wrong in why an MSP’s SEO agency isn’t getting it into AI search.

I’ll add one red flag that is mine, not Google’s. A report that stops at rankings. Rankings are a means, and a firm that reports the means and never the end is hiding from the end.

How to Choose an SEO Agency That Can Talk to a Technical Buyer

Your buyer isn’t a consumer. It’s an IT director comparing providers over six weeks, or an owner who wants to know what a Microsoft 365 migration does to downtime, or a finance lead who found you through a narrow question and will leave in ten seconds if your page gets the answer wrong. They search in specifics. Narrow, technical, impatient.

A writer who can’t tell a PSA from an RMM writes pages those buyers close fast, and the cost lands twice, because the agency bills for the draft and then your technical lead spends an evening rewriting it, which quietly makes you the writer. You’re just paying someone else for the privilege.

Two tests work every time. Ask for a sample paragraph on your hardest service, written before the contract, and have someone who delivers that service read it. Then ask the agency to explain your offer back to you in two minutes. If it can’t, it can’t write it. Hard to fake, either way. Not every agency is worth hiring, the same way not every client is worth keeping, and fit is where I’d draw the line.

If you’re an MSP and you’re choosing a wider marketing partner instead of search help alone, that’s a separate decision, and how to find the right MSP marketing firm covers it.

Who Should Own the Accounts When You Hire an SEO Agency

Agency guides tend to skip this part. Google doesn’t. If an SEO offers you an audit, its page says, grant read access to Search Console and no more, at least at that stage, because an audit should give you realistic estimates of improvement and of the work involved, not a way into your settings.

Search Console’s permissions help page describes three roles. An owner has full control and can add and remove users and configure settings. A full user can view all data and take some actions. A restricted user gets simple view rights.

Here’s my rule, and it’s judgment, not a Google requirement. You are the verified owner of Search Console, your analytics, your CMS, your domain registrar and your hosting. The agency gets the lowest role that lets it do the job. Their access is a loan. Yours is the asset. Our SEO onboarding checklist lists the role to give in each tool.

An agency that insists on holding those accounts holds your leverage, and when the contract ends, the history inside them can walk out the door with it, along with your ability to prove what the work did. Price that the way you’d price any risk. Ask what premium they’re charging for it. Google makes a related point about servers: if an SEO has FTP access, it should be willing to explain every change it makes.

Settle ownership early, in writing: our guide to SEO contract terms covers where it belongs. Then settle the reporting before the first invoice. Ask for a monthly report that ends at inquiries and pipeline, with the pages that produced them named. Our look at SEO lead generation covers how rankings turn into sales conversations. A report that ends at a traffic line is a report about activity.

How Long to Wait Before You Judge an SEO Agency

Google gives no number. Its hiring page says to ask what results to expect and in what timeframe, and leaves the answer to the agency, which is where the trouble starts. “Page one in 30 days” is a sales line. Is it ever true? Sometimes. Count on it? No.

For a sense of scale, Ahrefs published a timing study, dated May 2025. It took 1 million random URLs its crawler saw in September 2023 and checked whether any reached the top 10 of Google within a year. Only 1.74% did. Filtering to 2 million English pages created in October 2023 with real content raised that to 6.11%. Ahrefs adds that if a page isn’t in the top 10 after about six months, it’s worth updating.

Read the limits before you quote it. The pages are random, so many were never meant to rank, and the study measures new pages in Ahrefs’ own index and not any agency’s results, so it can tell you how slow ranking is in general and nothing about how fast one particular firm ought to move. The company also sells SEO tools. What it does support is modest. Ranking takes time, and few new pages get there fast. You can read the full Ahrefs timing study yourself.

So judge in two stages, and this is my rule of thumb, not Google’s. The first 90 days get judged on shipped work: tracking verified, technical fixes made, priority pages published, a change log you can read. Months four through twelve get judged on impressions and qualified inquiries. If the first stage is empty, don’t wait for the second. Simple rule.

Run the Selection in Six Steps

Order matters. Skip the first step and the other five turn into a beauty contest.

1. Write the one-page job described above, with the buyers, the services and the budget.
2. Shortlist three firms. Not eight.
3. Ask all three the same questions, in writing where you can, so the answers compare cleanly.
4. Call two references per firm. Google suggests asking whether the SEO was useful, easy to work with and produced positive results. I’d add one more: what went wrong, and what did they do about it?
5. Buy a small, bounded first project, such as an audit with read-only access, before any twelve-month retainer.
6. Score the finalists on evidence, subject knowledge, access terms, measurement and fit, then decide.

Then hold whoever you pick to one monthly question: what did this month’s work do for the pipeline? If the answer is a ranking, send it back. And if you want C4 in the comparison, book a growth strategy call and run these tests on us first.
