Start with the problem, not the list of agencies

Most agency searches begin with a search engine and a list of ten firms. That order is backwards. An agency can only be judged against a job you have defined, and without that definition every proposal looks reasonable.

Before the first call, write down four things. The business outcome SEO must serve, such as more qualified demo requests or more sales of one product line. The pages that already earn revenue, because those are the pages you will protect. What your own team can review and approve each month. And the budget you can keep for at least six months. Organic results take time to build, so a budget you cut in the third month will rarely produce the results you were paying for.

Decide which type of partner you need

"SEO agency" covers very different businesses. A full-service agency runs strategy, content, technical work and links under one contract. A specialist handles one bounded problem well, such as a site migration or a technical audit. A freelance consultant suits a single site with a limited scope. Some companies pair software with an internal owner who acts on the recommendations every week.

The in-house route has its own trade-offs, which we covered in SEO agency vs in-house SEO. This article assumes you have already decided to buy outside help and need to choose the right partner.

Partner type	Best when	Watch out for	Typical contract
Full-service agency	You want one accountable team across strategy, content and technical work	Junior staff run the account while the senior person sells it	Monthly retainer, often with a minimum term
Specialist (technical or links)	You have a clear, bounded problem such as a migration or a broken internal linking structure	Gaps outside the specialty that nobody covers	Project fee with defined deliverables
Freelance consultant	One site, limited scope, and you want direct access to the decision maker	Capacity: one person, one holiday, one illness	Hourly or small monthly retainer
Software plus internal owner	You have someone who can act on recommendations every week	The owner has no time left to execute	Software subscription plus internal salary

Test whether they can prove their results

Ask for three client references you can call. Ask at least one of them a question the agency did not prepare them for: what went slower than promised, and how the agency handled it. Then ask the agency to show Google Search Console data from a past client, anonymized if needed: clicks, impressions, average position by query and the date range. An agency that is confident in its method will show this without hesitation. One that only sends slides with percentage increases has not told you what those percentages measure.

Next, check the agency's own search footprint. Search for the services it sells and see whether its site appears, and for which pages. A strong position on competitive service terms is a good sign. A missing position on the terms it sells to you is a warning, though not a verdict, since many good agencies rely on referrals.

Finally, look at how the agency earns links, because a backlink profile reveals a lot about its methods. Run its domain through a backlink checker and look at who links to it. Are those links from relevant sites that editors chose, or from directories and pages created only to host links?

Read the proposal like an auditor

A proposal should answer five questions in writing: what work is included, who does it, what you receive each month, how success is measured, and how you can leave. If one answer is missing, the proposals cannot be compared fairly, whatever their prices suggest.

Start with the deliverables. "Monthly SEO optimization" describes effort, not output. "Four articles per month, each with a brief, a target query, an internal link plan and a draft in your CMS by the 10th" describes something you can check. Then read the reporting section and ask what a report contains. A useful report lists pages, queries and the changes made, and says what the next month's work will be. Our guide to SEO reporting shows a full structure you can ask for.

Recognize the red flags, and why each one matters

Google's own guidance on hiring SEO help is short and worth reading before any sales call. It says that no one can guarantee a number one ranking on Google, and it tells you to be wary of firms that email you out of the blue. The page is Do I need an SEO?, and the screenshot below shows the section.

Guaranteed rankings or guaranteed traffic

The red flag is a promise of a position on a set date, or of a fixed number of visits. Google decides how it ranks pages, and nobody outside Google controls that. What you can ask for is a commitment the agency does control: the pages it will optimize, the content it will publish, the technical issues it will fix, and the date by which each one ships.

If you hear a guarantee, ask what happens when the target is missed. A refund for the last month tells you the promise was about the agency's invoices, not your results.

Cold outreach about your site

An email that says it has found errors on your site, often with a free audit attached, is a common opening move for low-quality firms. Good agencies do send audits, but usually after you have engaged them or asked for one. Check the sender's domain, search for the firm's name next to the word reviews, and reply with a short list of questions. Their answers will tell you more than the audit does.

Cheap links at volume

Google's spam policies classify buying or selling links for ranking purposes as link spam, and they also list excessive link exchanges. A proposal that promises a large number of placements for a low price is therefore not an asset. It is a risk that can end in a manual action against your site. Ask for the list of linking domains and for the editorial process behind each placement. Our article on backlink exchange explains the difference between a legitimate exchange and a scheme.

The rule itself is in Google's spam policies, shown below.

Tools described as approved by Google

Google does not evaluate or endorse third-party SEO tools, and its guidance warns against tools that claim to be "approved" or "acceptable" by Google Search. Treat any reference to a Google approval, certificate or partner status as a claim to verify, not as a credential. Ask the agency what each tool measures, and whether you can export its data without the agency present.

No method, only outcomes

An agency that will not describe its methods in writing is asking you to trust it blindly. Ask for a short description of each stage: how it chooses target queries, how it briefs writers, how it checks technical issues and how it earns links. A good agency is glad to explain this, and the explanation also shows you whether its team knows what it is doing.

Check access and ownership before you sign

Many agency relationships go wrong on access, not on advice. Keep ownership of every account that holds your data: your Google Search Console property, your Google Analytics property, your tag manager container, your CMS and your domain registrar. Give the agency a manager or editor role, and keep the owner role yourself. If the agency owns the account, the data and the history leave with the agency when the contract ends.

Then ask the agency to check the health of your most important pages and to show each check in writing. A simple first test is the HTTP status and redirect of a page you want to rank. Run this in a terminal:

curl -sI https://www.example.com/services/ | grep -iE "^(HTTP|location)"

The first line shows the status code. A 200 means the page loads. A 301 to another address is normal when a page has moved, but the target must be the final version of the page, not the start of a redirect chain. A 404 or a 5xx on a page you want to rank is a problem to fix before any content work starts. Then ask the agency to show the Manual actions report in Search Console, which tells you whether Google has applied a manual action to your site. Our technical SEO checklist lists the next checks in order of impact.

Run a paid pilot before any long contract

A pilot tests the working relationship and the first results, not the final outcome. Choose one group of pages, such as one product line or one service, and agree on three targets the agency can influence: the number of those pages indexed in Search Console, the impressions and clicks for an agreed list of target queries, and the number of pieces delivered on time and approved by your team. Write down the baseline before the first day, using the last few months of Search Console data, so nobody argues about the starting point later.

The funnel below shows how the choice narrows. Most of your time should go to the middle stages, where you can compare written proposals and listen to how the team answers questions.

Keep the pilot short enough to end cleanly and long enough to show a trend. Search results move slowly, so judge the trend in indexing and impression data rather than a single week's clicks. At the end, you should be able to answer one question: would you pay for the next period on the same terms, with the same people?

Compare pricing models and what really drives the cost

Four pricing models are common, and each one moves risk to a different party. A monthly retainer pays for ongoing team time, which suits sites that need continuous work. A fixed project fee pays for a defined deliverable, such as an audit or a migration plan, and fits a bounded problem. An hourly rate is easy to start but hard to budget, and it gives little incentive to finish quickly. A performance-based fee ties payment to results, which sounds fair until you have to agree on what caused a result.

Pricing model	What you pay for	Main risk
Monthly retainer	Ongoing team time and output	Scope drifts, and the hours are hard to see
Fixed project fee	One defined deliverable	Too narrow, and any new work needs a new contract
Hourly rate	Time spent	Hard to forecast, with little pressure to finish
Performance-based fee	A share of a measured result	Disputes over attribution, and an incentive to chase easy wins

The main drivers of price are the size of the site, the number of languages, the amount of technical debt, the volume of content to write and edit, how competitive the target queries are, and how links are earned. Two agencies quoting different prices may be quoting different work, so compare scope first. You can estimate your own budget with the SEO budget calculator, and our SEO cost guide explains the pricing logic in more depth.

Set reporting you can check without the agency

You should be able to verify three things yourself each month, using accounts you already own. In Search Console, the performance report shows clicks and impressions for your target queries and pages. The indexing report shows which pages Google has indexed and which it has excluded, with reasons. In Google Analytics, the organic search channel shows the conversions that started from search. If the agency's monthly report cannot be reproduced from these sources, ask why.

Search Console keeps performance data for a limited period, so export the data every month and store it yourself. The routine below takes less than an hour and keeps the relationship honest.

1. Export queries and pagesDownload the performance report for the target queries and the key pages.
2. Compare the periodUse the same date range from last year, or the previous period of equal length.
3. Read the indexing reportLook for new exclusions or errors on the pages you care about.
4. Match changes to datesCheck which pages changed, and whether a change coincides with a shift in clicks.
5. Decide the next monthAgree on the priorities and on the pages to protect from any risky change.

Ask whether they measure AI answers too

Google rankings are only part of the picture. Buyers now ask ChatGPT, Claude, Gemini and Perplexity to recommend suppliers, and those assistants answer with sources. An agency that covers this should explain how it tests prompts, what it records (the brands mentioned, the sources cited, and where your brand appears in the answer), how often it re-runs the tests, and how it handles answers that change from one day to the next. Ask for this method in writing.

The two disciplines overlap but measure different things, as the comparison below shows. Our article on GEO vs SEO explains the overlap, and the GEO strategy guide describes how to plan the work.

If you would rather run part of this work in-house, Sorank is built for that case. Its SEO teams page describes keyword research, article production, link exchange and AI visibility tracking in one tool, so the in-house owner can act on the data without waiting for a monthly report.

Common mistakes, and how to avoid each one

Choosing on price alone

What it is: picking the lowest number without comparing what each number buys. How to spot it: proposals with different deliverables but similar totals, and no price split by deliverable. How to fix it: rewrite each proposal into the same five answers from earlier, then compare them line by line. The cheapest option is often the one with the fewest deliverables.

Giving away the accounts

What it is: letting the agency create your Search Console property or your Analytics account under its own login. How to spot it: when you ask for access, you receive a login from the agency's domain instead of an invitation. How to fix it: create the accounts yourself, add the agency as a manager or editor, and keep the owner role. If the agency has already created them, ask for ownership to be transferred in writing before work starts.

Signing without an exit clause

What it is: a contract that renews automatically with no practical way out, or with no handover of content, redirects and reports. How to spot it: the contract says nothing about notice, and nothing about what you receive when the work ends. How to fix it: require a short notice period, a handover of every content file and redirect list, and a copy of every report produced.

Publishing content you have not checked

What it is: putting articles live because the agency delivered them on time. How to spot it: claims with no source, figures you cannot trace, and advice so generic it could apply to any site. How to fix it: have one person on your team check each article against its sources before publishing. Our guide to SEO mistakes lists the on-page errors to look for during that review.

A 30-day plan to choose well

Use this sequence to go from a shortlist to a decision in about a month. The order matters: proof and access come before price, and the pilot comes before the long contract.

1. Define the outcomeWrite the business goal, the pages that matter most and the budget range you can keep.
2. Build a shortlistChoose partners of the type you need, and ask each one for two references.
3. Verify the proofCall the references, check the agency's own search footprint and look at its links.
4. Compare written proposalsRewrite each proposal into the same five answers, then compare them line by line.
5. Run a paid pilotAgree the baseline and three targets in writing, then review the trend at the end.
6. Sign with exit termsKeep account ownership, a short notice period and a full handover of content and reports.

If you can complete all six steps, you will know more about each agency than most buyers do. The choice then becomes a question of fit, not of who sounds most confident in the first call.
