The B2B SEO Tools Everyone Overlooks

by Mark | Apr 29, 2026

There is no shortage of B2B SEO tools. There is a significant shortage of B2B teams that know what to do with them.

Most businesses have Semrush or Ahrefs. They run audits. They pull keyword reports. They produce content. And then they sit in a meeting and argue about which keywords to go after, which pages are worth fixing, and whether the whole strategy is actually working, without a structured way to answer any of those questions.

The tools are not the problem. The missing layer is decision-making: a repeatable way to pressure-test a strategic call before you commit time and budget to it.

After 26 years of running B2B SEO campaigns, we built that layer ourselves. We are sharing it here for free. Then we will cover the data tools that feed into it, because you need both.

The Tool That Changes How You Use Everything Else

Before we get to Semrush, Ahrefs, and Screaming Frog, we want to introduce something none of the other B2B SEO tools lists mention, because it did not exist until recently.

Five Minds is a free AI decision framework built by 15DegreesNorth, based on Andrej Karpathy’s LLM Council methodology. Karpathy, former head of AI at Tesla, founding member of OpenAI, developed the concept of running a question through multiple AI perspectives simultaneously, having them peer-review each other, then synthesising a single structured verdict. We adapted that for B2B decision-making and packaged it as a tool anyone can use.

The premise is simple. You ask one AI a question, you get one perspective. You run the same question through Five Minds, and you get five independent perspectives that challenge each other, followed by a synthesised verdict that tells you where the thinking converges, where it conflicts, and what you should actually do.

For B2B SEO, this changes everything about how you make strategic decisions.

The Five Minds

Each mind represents a distinct thinking style. They are designed to create productive tension with each other:

The Devil’s Advocate: challenges every assumption, finds the flaw before it finds you
The Strategist: strips away the surface question, rebuilds from first principles
The Opportunist: looks for the upside nobody else is seeing
The Buyer: thinks exactly like your target customer, catches the curse of knowledge
The Operator: only cares about what actually gets executed on Monday morning

Your question goes to all five simultaneously. Each responds independently. Their responses are anonymised and peer-reviewed. A chairman then synthesises everything into a structured verdict with a clear recommendation and one concrete next step.

What This Looks Like in Practice

Here is the kind of question Five Minds is built for:

“We have found a keyword cluster with 3,400 monthly searches and low competition. Should we build a content hub around it or focus the budget on fixing the pages that almost rank?”
“Our main competitor just published 40 pieces of content targeting our core keywords. Should we respond directly or hold our current strategy?”
“We are a 12-person B2B SaaS company. Should we invest in technical SEO this quarter or content?”
“This service page gets traffic but converts badly. Do we rewrite it, restructure it, or kill it and redirect?”

These are not questions Semrush can answer. They are judgment calls. And most B2B teams make them based on instinct, internal politics, or the opinion of whoever spoke most confidently in the last meeting.

Five Minds replaces that process with something structured, repeatable, and genuinely useful. It gives you 5 new sets of AI eyes on the problem. Once the question is asked, Five Minds will start deliberating.

Once Five Minds has deliberated, you will get your answer from the Chairman, which is called the Verdict. If you click at the tab at the bottom called “Full Mind Responses” You will see each mind’s individual full response in detail.

How to Get It and Use It

How to Install Five Minds in Claude

Five Minds runs inside Claude, the AI assistant made by Anthropic. You will need a free or paid Claude account at claude.ai.

Step 1. Download Five Minds file using this link Five Minds

Step 2. Unzip the file, don’t do anything with it yet and then follow the rest of these instructions

Step 3. Go to claude.ai and open a new conversation

Step 4. Click the paperclip or attachment icon in the chat input and upload the file you just downloaded

Step 5. Type the following message and hit send:

Please render this as a React artefact

Be patient! Claude will build the Five Minds interface in the panel on the right, but it takes a couple of minutes to compile it. You can use it straight away once it appears.

Do I need a paid Claude account?

The free tier works. A paid Claude Pro account (around £18 per month) gives you faster responses and higher usage limits, which matters when running a full Five Minds session, as it makes around nine separate AI calls per run.

Important Note:

Important: How Five Minds Works Inside Claude

Five Minds runs as a React artefact inside your Claude chat window. This means it is not a saved app or an installed tool. It lives inside the conversation you loaded it in.

Here is what that means in practice:

If you close the conversation, the interface disappears. It is not gone permanently, but you will need to reload it to use it again.

If you close the artefact panel by clicking the X on the top right-hand side, you can bring it back by clicking the grid icon in the top right of the chat window and selecting Five Minds from the list.

If you want to use it again in a new conversation, simply upload the five-minds.jsx file you downloaded, type “Please render this as a React artefact,” and it will load straight away.

Our recommended approach is to keep one dedicated Claude conversation just for Five Minds. Load it once, name it Five Minds, and return to it every time you need it. The artefact will be waiting for you in that chat each time you open that conversation.

A note on Claude accounts. The free tier works, but if you are running multiple Five Minds sessions, you may hit usage limits. Claude Pro, at around £18 per month, removes those limits and gives you noticeably faster responses.

Using Five Minds in ChatGPT, Gemini or Grok

You do not need Claude to use Five Minds. If you already use a different AI tool, you can run the same methodology manually. Plan for around 15 to 20 minutes the first time.

The process has three stages.

Stage 1: Run Each Mind

Open your AI tool of choice. Run each of the five prompts below as a separate conversation, or clear the context between each one. This is important as you do not want the minds to see each other’s responses at this stage.

Replace [YOUR QUESTION] with your actual decision in each prompt.

Prompt 1: The Devil’s Advocate

You are The Devil’s Advocate on a Five Minds decision council.

Your role: Challenge every assumption in the strategy. Find the flaw before clients, competitors or budget does. Assume there is a fatal flaw and try to find it.

The question: [YOUR QUESTION]
