B2B SEO consultant: what to check before you hire

A B2B SEO consultant finds why a firm’s site misses buyers and fixes the pages, structure, content and signals that bring it into the results.

For a professional firm, the work usually covers three areas.

1. Technical health

   Pages load cleanly, link correctly and get indexed so Google can read them.

2. Buyer intent

   The consultant maps the words a serious buyer types, not just the words that get clicks.

3. Authority and trust

   Real pages, case studies and third-party mentions show Google and AI assistants that the firm is a known name.

A good consultant also reports on enquiries and clients, not just rankings, because a ranking that never turns into a call is not worth paying for. In B2B, search volume looks small and that is fine, because one right enquiry can be worth more than many casual visits.

A proper B2B SEO audit tells you where you are losing buyers today, not just where your rankings moved last month.

It should cover five things.

1. What your site can be found for now

   Which pages rank, which words bring enquiries, and which service pages are missing.

2. What buyers actually ask

   The questions partners hear on calls, written into pages that answer them.

3. What the AI engines say about you

   We check ChatGPT, Gemini, Perplexity and AI Overviews, because a firm can rank on Google and still be left out when a buyer asks an AI for a shortlist.

4. What competitors do

   Where the firms you lose work to are named, and what they publish that you do not.

5. What to fix first

   A short list ordered by likely client impact, with a clear owner and a way to measure it.

Skip any audit that only sends a spreadsheet of broken links and a promise to write more posts.

What you pay depends on the work, the market, and whether you buy advice or have the work done for you. There is no useful single price, because two firms of the same size may need very different jobs.

The fee is only part of the decision. Ask what you own, what happens if you stop, and whether the work is tied to enquiries rather than traffic.

A consultant gives you one experienced view; an agency gives you a wider set of skills and more cover when people leave.

1. A consultant

   Best for a clear question, a short project or teaching your own team what to do.

2. A traditional agency

   Best when you need several people: technical, content, links and reporting.

3. An AI-led agency

   Best when you want the work done for you and checked week by week, including how ChatGPT and Gemini describe your firm.

A consultant may cost less to start, but the work can stall when you become the person who must act on every recommendation. For an established firm with a real budget, the question is not consultant or agency. It is whether the supplier can both fix the site and keep it updated as search changes.

SEO is still worth paying for in 2026, because buyers still search, but the results now include AI answers and the work has to cover them.

The danger is paying for last decade’s playbook: endless thin pages and a report full of rankings nobody asked for. A serious buyer may ignore a clever term from a tool and ask a narrow question about their problem. Then they compare the firms that show up.

Our AI SEO agency treats search as three connected jobs: Google rankings, being named in AI answers, and turning those visits into enquiries. That matters because the shortlist a buyer sees may now come from an AI assistant as well as from Google.

The question is no longer whether SEO is worth it. It is whether your consultant is checking the places where buyers now look.

B2B search is different because the right answer is worth far more than a high number of visits, and the words buyers use are narrower.

A consumer may search for a quick purchase. A B2B buyer is usually researching a problem that carries real cost, risk or delay, and they compare the firms they find. For a solicitor, an accountant or a consultancy, the page that wins is not the one with the most traffic; it is the one that answers the exact question and proves the firm has done it before.

1. Fewer searches, higher stakes

   One well-matched enquiry can be enough to justify the work.

2. A considered choice

   More than one person may review the firm before a partner signs off.

3. The proof matters more

   Case studies, named sectors and clear explanations beat clever headlines.

That is why a B2B consultant should start with the questions your clients ask, not a generic keyword list.

Nothing is replacing SEO outright; what has changed is that search now happens in more than one place.

A buyer may still type a question into Google. They may also ask ChatGPT, Gemini or Perplexity to name the best firms for a particular matter. The old work of getting pages indexed and relevant still matters. The newer work is making sure the AI engines describe your firm accurately and cite your pages.

1. Search engine optimisation

   Your pages rank on Google for the words buyers type.

2. Generative engine optimisation

   Your firm is the answer AI assistants give when buyers ask a general question.

3. Answer engine optimisation

   Your pages answer a specific question so clearly that an AI can quote them.

We explain the difference in plain terms, including which one wins clients for a service firm, in our GEO vs SEO vs AEO guide.

Before you hire a B2B SEO consultant, check that they sell work, not just advice.

1. They ask about clients, not only keywords

   A good consultant starts with who buys from you and why, then works back to search words.

2. They can show the work being done

   Ask to see the actual pages or changes they made, not a screenshot of a green chart.

3. They report on enquiries and meetings

   Rankings are a supporting measure. The output that matters is whether the right firms get in touch.

4. They tell you what will not work

   A consultant who promises fast page-one rankings for every term is selling theatre.

Also ask how they handle AI search, because a consultant still selling only Google rankings is doing half the job now.

The right questions expose whether the candidate can produce work in your sector, and whether you will own it.

1. Which pages will you change first, and why those?

   The answer shows whether they saw your business or just your domain name.

2. Who writes the pages?

   If the answer is a low-cost writer with no sector knowledge, your brand may get bland pages that say nothing.

3. What do I own if we stop?

   You should own your domain, your content and your data. Our guide to AI vendor lock-in explains the contract checks.

4. How do you check what AI engines say about me?

   This is now a basic question for any professional firm.

5. What do you report, and how often?

   Ask for a plain note you can read in five minutes.

The usual failure is not tactics; it is work that never connects to the firm’s real clients.

1. The site gets traffic that never enquires

   Pages rank for words too broad for your buyers, so the phone stays quiet.

2. Content reads like a template

   It says the same things every competitor says and gives a buyer no reason to choose you.

3. The report hides the truth

   A chart of impressions can rise while qualified enquiries fall.

4. The work stops when the consultant leaves

   No one in the firm knows why the pages exist or how to update them.

We see this often in professional services marketing. A consultancy with partners cannot afford to look generic, so every page has to be written in the firm’s real voice and checked by a person.

An AI-led SEO agency is the stronger choice when you want the pages, the checks and the weekly reports done for you, not just recommended.

In a partnership, a consultant’s strategy can sit unread when every partner is busy delivering client work. An AI-led agency pairs the plan with the doing. The routine jobs run: pages are rewritten, AI answers are checked, and the work is reported in plain language.

This is not a replacement for judgement. A person still approves what goes live, and the firm’s voice stays in charge. The AI does the heavy typing and checking.

We are an AI marketing agency for service firms, so we build and run the system rather than selling a platform. For a firm with a real budget, that difference is often the one that turns advice into new enquiries.

We run AI search for service firms in one system: the website, the AI answers and the follow-up all read from the same record of what the firm knows. That record stops your website, your sales team and your articles from saying different things.

1. Pages are rewritten for buyers

   Each page answers a real question a partner hears, in the firm’s voice.

2. AI answers are checked weekly

   We see what ChatGPT, Gemini, Perplexity and AI Overviews say about the firm, and we work to correct it.

3. Enquiries go into one place

   When a page works, the resulting enquiry is followed up instead of sitting in a partner’s inbox.

Our AI SEO agency runs on that system. We have deployed 500+ AI agents, so the same checks that run your marketing can run across the rest of the firm.

A firm with a real budget should hire for a system that produces work month after month, not for a one-off project.

1. Do you want a plan or a working system?

   Buy a consultant for the plan. Buy an agency or AI-led service for the system.

2. Do you have time to manage the work?

   If not, choose the route where someone else runs it and reports in plain English.

3. Will the work survive a staff change?

   A system with your content in one place is easier to keep when a team member leaves.

If you are still weighing the route, start with a free AI audit. Put in your website and see where your firm stands across search and AI answers before you commit to anything. The audit does the first pass for you, so you can judge the work rather than the pitch.
