How to Choose an SEO Agency in 2026: Questions, Red Flags and Contracts
How to choose an SEO agency in 2026: what good SEO work includes, Google's own questions to ask, spam red flags, reporting, contracts and how to compare proposals.
To choose an SEO agency, look for one that starts by learning your business and customers, explains exactly what it will do and why, follows Google's published guidelines, reports on business outcomes rather than vanity metrics, and never promises guaranteed rankings. A good agency combines technical SEO, content and digital PR or link earning in proportions that suit your site. This guide gives you the questions to ask (including the ones Google itself suggests), the red flags to avoid, contract terms to check and a way to compare proposals.
Start with Google's own advice on hiring an SEO
Google publishes a page called Do you need an SEO? with practical tips for hiring one. Its suggested interview topics include:
- Examples of previous work and client success stories.
- Whether the SEO follows Google Search Essentials.
- Which results they expect, and over what timeframe.
- Their experience in your industry and in your country or city.
- Their experience with international sites, if you have one.
- How long they have been in business and how they will communicate with you.
Google also suggests noticing whether the SEO asks about your business, your customers and your competitors. A good agency should be curious about how you make money before it talks about keywords.
The same page warns that no one can guarantee a number one ranking on Google, that you should be wary of SEOs claiming a special relationship with Google, and that you are responsible for the actions of any company you hire. If an SEO creates deceptive or misleading content on your behalf, your site could be removed from Google's index. That last point is the main reason to choose carefully: the risk sits with you, not the agency.
What good SEO work includes
SEO is not one activity. Most effective programmes combine several kinds of work, weighted to your situation.
| Area | Typical activities | Most important when |
|---|---|---|
| Technical SEO | Crawling and indexing checks, site structure, redirects, structured data, page speed | Large sites, migrations, sites built on complex platforms |
| Content | Keyword and intent research, content planning, writing and updating pages | Sites competing on informational and comparison searches |
| Local SEO | Business profile optimisation, location pages, reviews, local citations | Businesses serving customers in specific cities or regions |
| Digital PR and link earning | Research, stories and assets that earn coverage and links naturally | Competitive markets where authority matters |
| Analytics and conversion | Tracking, reporting, landing page improvements | Every engagement, so results are measured in leads and revenue |
Ask each agency which areas it would prioritise for your site and why. If every proposal you receive looks identical regardless of your situation, the agency is probably selling a package rather than a strategy.
Page experience is part of technical SEO. Google's web.dev guidance on Core Web Vitals sets "good" thresholds of a Largest Contentful Paint within 2.5 seconds, an Interaction to Next Paint of 200 milliseconds or less and a Cumulative Layout Shift of 0.1 or less, measured at the 75th percentile of page loads. A technical SEO agency should be able to explain where your site stands against these numbers and who will fix any issues, the agency or your developers.
Red flags: tactics that put your site at risk
Google's spam policies describe practices that can lead to lower rankings or removal from search results. Be wary of any agency that proposes, or will not rule out:
- Link schemes: buying links, large-scale link exchanges or private blog networks.
- Scaled content abuse: generating many low-value pages mainly to manipulate rankings, whether written by people or produced with automation.
- Doorway pages: many near-identical pages targeting slight keyword variations that funnel users elsewhere.
- Cloaking or sneaky redirects: showing search engines different content from what users see.
- Expired domain or site reputation abuse: using another site's established ranking signals to host unrelated content.
- Keyword stuffing and hidden text.
Other warning signs are commercial rather than technical:
- Guaranteed first-page or number one rankings.
- Unsolicited emails promising quick results.
- Secret methods the agency will not explain.
- Reports that show only rankings for obscure keywords, with no traffic, leads or revenue data.
- Contracts that lock you in for a long period with no performance review points.
- The agency owning your Google Search Console, analytics or Business Profile accounts.
Questions to ask beyond Google's list
- What did your initial review of our site find, and what would you fix first?
- Which of our competitors are winning in search, and why do you think that is?
- How will you decide which keywords and topics to target? How do they connect to our revenue?
- Who will write content, and how will you make sure it reflects our real expertise?
- How do you earn links, and can you show examples of coverage you have won for clients?
- What will you need from our developers, and how do you hand over technical recommendations?
- What will the monthly report include, and how often will we review results together?
- How do you handle algorithm updates that affect our traffic?
- Who exactly will work on our account, and how many other clients do they manage?
Reporting: measure what matters to the business
Agree on measures before the work starts. Rankings and traffic are useful indicators, but they are not the goal. A sensible reporting set usually includes:
- Organic sessions and conversions (leads, sales, sign-ups) from search, by page type.
- Visibility for a defined set of priority topics, not hundreds of random keywords.
- Indexing and crawl health from Google Search Console.
- Work completed this period and planned for the next, with owners and dates.
- Issues blocking progress, such as developer time or content approvals.
Make sure the data comes from accounts you own. The agency should have access, but you should hold admin rights to Search Console, analytics and any Business Profile listings.
What the first few months should look like
A clear onboarding plan is one of the best signs of a professional agency. Ask each shortlisted agency to describe what will happen in the first three months. A typical, sensible sequence looks like this:
- Access and measurement: access to Search Console, analytics and your content management system, with tracking checked so leads and sales from search are recorded correctly.
- Audit and research: a technical audit, content inventory, competitor review and research into what your customers search for at each stage of buying.
- Prioritised roadmap: a short list of the changes with the biggest expected impact, with owners and dates, rather than a hundred-page audit nobody acts on.
- Quick fixes: technical issues such as broken redirects, indexing problems or missing page titles fixed early, often by your developers with the agency's guidance.
- First content and outreach work: improvements to your most important existing pages before new content is produced.
- First review meeting: a joint look at early indicators and an agreed plan for the next quarter.
Ask how much of your own team's time the plan needs. SEO often stalls because developer time or content approvals are not available. A good agency will raise this during the sales process, not after the contract is signed.
Contract terms to check
- Scope: a clear list of monthly activities and deliverables, not just "SEO services".
- Term and exit: a reasonable initial term with review points, and a notice period you can live with.
- Ownership: content, research and reports created for you belong to you.
- Access: agency access to your accounts is removed at the end of the contract.
- Third parties: whether any work is subcontracted, and to whom.
- Approval: no changes to your site, content or links without your sign-off.
How to compare SEO proposals
| Criterion | Strong proposal | Weak proposal |
|---|---|---|
| Diagnosis | Specific findings about your site and competitors | Generic checklist |
| Strategy | Priorities linked to your revenue and customers | Keyword list with no rationale |
| Methods | Explained clearly and consistent with Google's guidelines | Vague or secret methods |
| Expectations | Realistic timeframe and leading indicators | Guaranteed rankings |
| Team | Named specialists for technical, content and outreach | One account manager for everything |
| Reporting | Business outcomes from your own accounts | Rank reports only |
| Terms | Clear scope, review points and fair exit | Long lock-in |
Agency, consultant or in-house?
An agency suits most businesses that need several skills at once, such as technical fixes, content and outreach, without hiring a full team. An independent consultant can be a good fit for audits, migrations or coaching an in-house marketer. A full in-house team makes sense when search is a major revenue channel and you have the budget and management capacity to build one. Many businesses combine options: an in-house content lead supported by a technical SEO consultant, for example.

Frequently asked questions
Can an SEO agency guarantee first-page rankings?
No. Google states that no one can guarantee a number one ranking. Treat ranking guarantees as a red flag.
How long does SEO take to show results?
It depends on your site, competition and the work involved. Ask each agency what results it expects and in what timeframe, as Google suggests, and agree leading indicators to track along the way.
Who should own our Search Console and analytics accounts?
You should. Give the agency access, but keep admin ownership so you keep your data if you change suppliers.
Am I responsible if my SEO agency uses spam tactics?
Yes. Google says you are responsible for the actions of companies you hire, and deceptive tactics can lead to your site being removed from its index.
What should a monthly SEO report include?
Organic traffic and conversions, visibility for priority topics, technical health, work completed and planned, and anything blocking progress.
