How to Choose a B2B SEO Agency: What to Check Before You Sign

Start with how they pick keywords

This is the single best test of a B2B SEO agency. Ask them to explain how they would choose the first 20 keywords for your business. Their answer tells you whether they are chasing traffic or chasing buyers.

Here is the difference. A company selling SCADA software could write an article on “what is automation” and get thousands of visits, mostly from students. A page that ranks for “SCADA software for water utilities” may get a handful of visits a month, but every one of them could be a utility engineer with a budget. In B2B, a small number of the right visitors beats a big number of the wrong ones.

Good signs to listen for:

• They ask about your best customers, average deal size and sales cycle before they talk about keywords.
• They look at sales call notes, RFPs and the questions your team hears every week, not just keyword tools.
• They sort keywords by stage: problem searches, solution searches, comparison searches (“X vs Y”, “alternatives to X”) and buying searches (“pricing”, “for [industry]”, “near me”).
• They are happy to target low volume keywords when the intent is strong.
• They tell you which keywords they would not target, and why.

Ask how they report on leads and pipeline

Rankings are a means, not the goal. A useful agency report connects search activity to inquiries, and ideally to deals your sales team can see in the CRM. Ask to see a sample report (with client names hidden) before you sign.

Be fair here too. B2B attribution is messy. A buyer may read three of your articles, then come back a month later through a LinkedIn post and fill the form. A good agency admits this. It sets up form source tracking, a simple “how did you hear about us” field, and a CRM source field, and it looks at assisted conversions, not only the last click. This lead focus is how we run our own SEO and lead generation work.

Here is a simple outline you can ask any agency to fill each month. If a report cannot answer these questions, ask why.

Check their technical SEO skills

Many B2B websites have hidden technical problems. Product pages that look the same to Google. Resources locked behind forms so search engines never see them. A staging site that got indexed. A redesign that dropped half the old URLs without redirects. Content alone will not fix these.

Ask whether the agency is comfortable with:

• Crawling and indexing issues, using Google Search Console and a crawler.
• Page speed and Core Web Vitals, and how to fix them on your platform.
• Site structure and internal linking, so important pages get found.
• Structured data (schema) for your organization, products, articles and FAQs.
• Website migrations and redirect plans.
• Your CMS, whether that is WordPress, Webflow or something custom.

A good question: “Tell me about a technical problem you found on a client site and how you fixed it.” Listen for a specific story, not general words. It also helps if the agency can make the fixes itself instead of sending you a long list for your developer. That is one reason we keep website development and SEO in the same team.

Judge content quality by reading it

Your buyers are often experts: engineers, CFOs, HR heads, IT managers. They can spot thin, generic content in a few lines. If an agency produces articles that could be about any company, your brand looks weaker, not stronger.

Ask for two or three samples in a technical or complex subject, then read them properly. Good B2B content usually:

• Answers the main question in the first few lines.
• Uses real examples, numbers from your own business and clear trade-offs.
• Is written for a specific job role, not “everyone”.
• Includes input from your own experts, not only from other websites.
• Ends with a sensible next step, such as a demo, a spec sheet or a consultation.

Look closely at link building methods

Links from other websites still matter for rankings. But how an agency gets those links matters even more, because bad links can hurt you and waste your money.

Red flags to walk away from:

• Guaranteed rankings. No one controls Google, and Google’s own guidance on hiring an SEO says no one can guarantee a number one ranking.
• Link packages, such as “50 high authority links per month” at a fixed price.
• Private blog networks, or sites that publish anything for a fee.
• Refusing to show you where the links come from.
• Links from websites with no connection to your industry or country.

Better methods take more effort, but they last. Think industry publications, partner and association pages, original data or useful tools people want to cite, expert quotes for journalists, event and trade show listings, and turning existing brand mentions into links. Ask the agency to show you real examples of links it has earned this way.

Make sure they are ready for AI search

Buyers now ask Google AI Overviews, ChatGPT, Perplexity and Gemini questions like “best payroll software for mid-size companies in India” or “how to choose a CNC machining partner”. Each tool picks its sources in its own way, and most do not publish the details. What helps across them is the same groundwork: pages that answer clearly, facts that match across the web, and mentions on sites buyers trust. Your agency should treat this as part of SEO, not a separate magic service.

What real readiness looks like:

• Clear, consistent facts about who you are, what you sell and who you serve, across your website, LinkedIn and directories.
• Pages that answer questions directly, with short summaries and FAQs.
• Accurate structured data that matches what is on the page. It helps search engines read your pages, though Google says no special schema is needed for its AI features (Google’s guidance).
• Mentions on trusted third-party sites, reviews and comparison pages.
• A simple way to track how often your brand shows up in AI answers for your key questions.

Be wary of anyone who promises guaranteed placement inside ChatGPT. An honest agency will tell you this area is still new, that measurement is rough, and that the basics of good SEO do most of the work.

Read the contract terms carefully

SEO takes months to show results, so some commitment is fair. A first term of around three to six months, followed by monthly renewal with a notice period, is common and reasonable. A long lock-in with no way out is not.

• Deliverables: what exactly happens each month (pages, fixes, links, reports).
• Ownership: all content, Google Analytics and Search Console accounts should be in your name.
• Exit: what you get if you leave, including content files, keyword research and link records.
• Team: who will actually work on your account, and how senior they are.
• Rhythm: how often you meet, and who your single point of contact is.
• Price changes: what triggers extra fees, such as additional pages or content.

Questions to ask before you sign

Take this list into your next agency call. The answers will tell you more than any proposal deck.

1. How would you choose our first 20 keywords?
2. What will you report on each month, and can I see a sample?
3. How will you track leads from search into our CRM?
4. What technical issues do you see on our site right now?
5. Who writes our content, and will they talk to our experts?
6. Where have your recent links come from? Can you show examples?
7. How do you approach AI search and AI Overviews?
8. What should we expect at three, six and twelve months?
9. What happens to our content and data if we leave?
10. When would you tell a company that SEO is not the right channel for them?

The last question is the most revealing. A good agency will have a clear, honest answer.

When an agency is not the right choice

Hiring a B2B SEO agency is not always the best move. It may be the wrong time if your website is broken and needs a rebuild first, if no one in sales follows up on inquiries quickly, or if your market is so small that almost no one searches for what you sell. In that last case, account-based outreach, events and partnerships may work better. And if SEO is core to your business and you can afford a full team, building in-house may make more sense over time. Our in-house SEO vs agency guide covers that choice, and if you sell industrial products, see our checklist for manufacturing SEO agencies.

If none of that applies, an agency that starts from your sales goals can move faster than a new hire. At Hypergrow, we run SEO alongside website and content work as one team, and we report on inquiries, not hours. You can see some of the websites we have built for companies like JER HR Group, CompBldr and SecMark in our work, and read how we approach SEO for B2B technology companies.
