I will admit something that the people selling SEO software would rather I did not. I run a search business, and the number of paid tools I open in a normal week is two. Everything else on the long lists of “best AI SEO tools” I have tried and quietly cancelled.
That matters because those lists are not written for you. They are written for agencies, usually by the tool vendors themselves, and they quote American prices for stacks that cost more each month than most UK owners spend on their accountant. So this is the short version: the free layer that handles most jobs, one paid tool for each job that actually needs one, what each is pointless for, and the one skill that lets you skip half the stack.
What are AI SEO tools, and which jobs do they actually do?
AI SEO tools are software that uses machine learning or a language model to do one of four search jobs: audit your website, research what people search for, help you write pages, or track whether Google and the AI assistants mention you. That is the whole category. Any product that does not fit one of those four jobs is a dashboard looking for a problem.
The trick is to buy by job, not by brand. Semrush, Ahrefs and the rest sell bundles that cover all four jobs at once, which is why they cost what they cost. An owner with one website rarely needs all four done to a professional standard in the same month.
Here is how I would map it.
Which AI SEO tools are free, and how far do they get you?
Further than the vendors would like. Google Search Console, Bing Webmaster Tools and the free tier of Screaming Frog cover the first and fourth jobs completely for a site under 500 pages, and they are the exact data sources the paid tools resell back to you.
Search Console changed in June 2026 in a way that most owners missed. Google added generative AI performance reporting, so you can now see impressions your pages earned inside AI Overviews and AI Mode. It is impressions only. There are no clicks, no click through rate and no query breakdown yet, and the rollout was staged, so if the report is not in your account it may simply not have reached you. Even so, it is the first free, first party confirmation that an AI answer showed your page to someone.
Bing went further in February 2026 with an AI Performance report inside Webmaster Tools. It lists the pages Copilot cited, by day, and the queries it was grounding on. You can only export it as a CSV, there is no API, and it covers Copilot rather than ChatGPT. For a free report, I would still take it.
Screaming Frog is the odd one out: a desktop crawler built by a company in Henley on Thames that has quietly become one of the more useful AI SEO tools around. Version 22, released in June 2025, added direct integrations with OpenAI, Gemini and local models through Ollama, so while it crawls your site it can ask a language model to write a missing meta description for every page, or check whether each page actually answers the question in its heading. The free version crawls 500 URLs. Most UK businesses never need more.
Which paid AI SEO tools are worth the money?
For an owner, I would pay for at most one of these at a time, and I would pick it by the job you do most.
Keyword research: Ahrefs Starter at 29 US dollars a month. The full Ahrefs Lite plan is 129 dollars and Semrush Pro is just under 140, and both are agency tools. The Starter tier gives you the keyword database and the site audit for less than a quarter of that. It is pointless if you run a local trade with one service page. Search Console will tell you what you already rank for, and your customers will tell you what they type.
Writing briefs: Frase at 49 dollars a month. Frase, Surfer and Clearscope all do the same core thing: look at the pages that already rank for a term and tell you which subtopics and questions they cover. Clearscope charges 129 dollars for the privilege, and Surfer moved to euro pricing in late 2025, from 49 euros a month on an annual plan. Frase is the cheapest way to get the brief. None of them write the expertise, which is the part that gets you cited.
Tracking AI mentions: Rankscale at 17 dollars a month or Otterly at 29. Both run a fixed list of prompts through ChatGPT, Perplexity and Google’s AI features and record whether you are named. Semrush sells the same idea as its AI Visibility Toolkit at 99 dollars a month per domain for 25 prompts, and Ahrefs Brand Radar starts at 199 dollars. The enterprise trackers, Profound and Scrunch, start at custom quotes and 250 dollars a month respectively. An owner needs none of the enterprise tier. You need to know whether the assistants name you when someone in your town asks for what you sell, and the cheap trackers answer that.
One honest caveat on currency. Not a single one of these vendors publishes a pound price. Ahrefs, Semrush and Surfer serve euros to a European visitor and dollars to everyone else, so budget on the dollar figure plus VAT and whatever your card charges for conversion.
Can Claude Code replace most of these tools?
For the audit and research jobs, yes, and this is the part none of the vendor lists will tell you. Claude Code is Anthropic’s coding agent. It runs in a terminal window on your Mac or PC, you describe a job in plain English, and it writes and runs the code to do it. It comes with a Claude Pro subscription at 20 US dollars a month, or 17 on an annual plan, which is less than any tool in the section above.
What can a non developer realistically get it to do? In March 2026 someone with no coding background documented building a crawler that checks every page’s title, meta description, H1, canonical tag, image alt text and schema, then writes an HTML report, in three to five hours of describing what they wanted. That is the core of a Screaming Frog audit. In August 2026 an Australian agency published its own list of Claude Code SEO jobs: content audits from a Search Console export, striking distance reports of keywords sitting in positions 11 to 20, internal linking suggestions, and content briefs. There are now open source skill packs that teach it audits, schema generation and keyword clustering out of the box.
Here is the shape of a first afternoon.
- Export the last three months of queries and pages from Search Console as a CSV.
- Open Claude Code in a folder containing that file and ask it to group the queries into topics and show you which topics get impressions but few clicks.
- Ask it to crawl your site, list every page missing a meta description, and draft one for each in your tone.
- Ask it to generate the FAQ and LocalBusiness schema for your main service page and explain where to paste it.
That covers the research and audit jobs, with your schema thrown in, on a subscription you may already pay for. The output lands as files on your computer that you own and can rerun next month.
It does not replace everything. Claude Code has no backlink index, so it cannot tell you who links to a competitor. It cannot see rankings without a data source, so you still feed it Search Console. And it will happily write five hundred thin pages if you ask, which brings us to the real risk.
Where do AI SEO tools get businesses into trouble?
The danger is not using AI. It is using it to publish volume. Google’s spam policies, updated again in August 2026, define scaled content abuse as using generative tools to produce many pages without adding value, and on 15 May 2026 Google extended those same policies to cover what appears in AI Overviews and AI Mode. In January 2026 Google’s Danny Sullivan went on record warning against chopping content into bite sized chunks aimed at language models, which is exactly what several “AI optimisation” features in these tools encourage.
The data says the same thing from the other direction. Ahrefs analysed around 150,000 ranking pages in July 2026. More than 86 percent of top ten pages contained some AI written text, so nobody is being punished for a drafted paragraph. But only 4.6 percent were fully AI generated, pages that were at least 80 percent AI held position one less often than position ten, and heavily AI pages were indexed less and earned two to three times fewer impressions.
So use the writing tools to get a first draft and a brief. Then put in the part only you have: the price you actually charge, the job that went wrong last winter, the opinion your competitors are too cautious to publish. That is the material AI assistants quote, and it is covered in more depth in my search and AI visibility service, where the monthly work is largely about earning those mentions rather than buying another dashboard.
What would I buy this month if I were you?
Start with nothing. Connect Search Console and Bing Webmaster Tools if you have not, run the free Screaming Frog over your site, and spend one afternoon with Claude Code on the Search Console export. That alone will show you where you are leaking.
Then, and only then, add one paid tool for the job you keep hitting. If you publish weekly, Frase. If you are choosing between topics to write, Ahrefs Starter. If your customers ask AI assistants for recommendations before they call, Rankscale or Otterly. Review it after three months and cancel anything you have not opened.
I have watched owners pay 200 dollars a month for software they log into twice a quarter, because a list told them the professionals use it. The professionals use it because they look after forty sites. You look after one, and the game has shifted under all of us anyway: Ahrefs found the top organic result loses 58 percent of its clicks when an AI Overview sits above it, so the prize is now being the business named inside the answer.
The tools help you see whether that is happening. They do not make it happen, and the people who sell them know it. If you want a second opinion on which of these you actually need before you put a card down, get in touch or read a little about how I work. I would rather you spend the money on an afternoon learning to do the audit yourself than on another subscription that does it for you until you stop paying.
