Short answer
An AI SEO tool uses artificial intelligence to help with search optimization. Some write content, some audit a website and report problems, and some act on the site to fix them. Which kind you need depends on who does the work afterwards. Arcline is the third kind: it reads your whole website, fixes what is safe to fix and checks the result. It is free for one website.
The three kinds of AI SEO tool
The label covers very different products. It helps to know which kind you are looking at.
| Kind | What it does | What you still do |
|---|---|---|
| Writers | Draft articles, titles and descriptions with AI. | Check the facts, edit, publish and fit the text to your site. |
| Auditors | Scan a website and report problems, often with an AI summary. | Work out what matters and make every fix yourself. |
| Agents | Read the site, decide on fixes, make them and check the result. | Approve what you are not comfortable leaving to the tool. |
Many products mix two kinds. The useful question is who does the work after the report.
What AI does well in SEO, and where it falls short
- Good at: reading many pages fast, spotting patterns such as repeated titles or missing descriptions, drafting wording from your own text and explaining findings in plain language.
- Not good at: knowing the facts of your business, choosing a strategy, judging whether an article is really original and helpful, or guaranteeing a result.
Seven questions to ask before you choose
- Does it fix problems or only report them? A long list of warnings is the easy part.
- Can you approve changes first, and undo them? You should always be able to say no.
- Does it prove a fix worked on the live page? A change that was sent is not the same as a change that works.
- Does it cover AI search as well as Google? Look for answer engine optimization (AEO) and generative engine optimization (GEO), explained in AEO vs GEO vs SEO.
- Does it work with your website platform? Many tools can scan any site but fix only some.
- Is the price clear, and in your currency? Check what the free plan leaves out.
- Is the free plan real? Free should let you see your own results, not only a demo.
Where Arcline fits
Arcline is an AI SEO tool of the third kind. It reads your whole website, fixes what is safe to fix and checks the result on your live page.
- Reads up to 200 pages and scores your site in thirteen areas, including readiness for AI answers.
- Turns the findings into a plain-language to-do list with exact steps.
- Prepares fixes such as titles, descriptions, structured data and an llms.txt file, and sends them through GitHub, WordPress or Ghost after your OK (up to 10 a month on Free, unlimited on Premium), or by itself with the Premium autopilot.
- Opens the live page to confirm each fix and undoes any that fails.
- On Premium, asks AI assistants the questions your customers might ask every week and shows whether they name you. Free gives one snapshot of 5 checks.
Websites built on Wix, Squarespace, Shopify or Webflow can be scanned and scored, but the fixes are yours to make by hand, and Arcline lists them as exact steps. See which platforms it works with.
What an SEO optimizer changes for you
An SEO optimizer is a tool that changes your pages, not just reports on them. The changes that are safe to automate are small and specific:
- Page titles and search descriptions, drafted from your own pages.
- Social-media previews.
- A preferred-address (canonical) link that points to the page itself.
- Structured data built only from facts already on the page.
- Links between your own pages, on WordPress and Ghost.
- An llms.txt file for AI assistants, which not every AI system reads.
Some problems have no safe automatic fix: page speed, broken links, redirects and sitemap problems. A good optimizer says so and hands them to you with exact steps, as Arcline does. Read how it finds and fixes problems.
Is there a free AI SEO tool?
Yes. The Free plan of Arcline covers one website with the full scan, thirteen scores, the to-do list, a weekly re-scan and up to 10 fixes a month that wait for your OK. The autopilot, unlimited fixes, AI-answer tracking, content studio and competitor watch are Premium, at $9 a month.
Many free AI SEO tools limit you to one page or a handful of checks, so compare what you actually get. See pricing for the full list.
Common questions
Are AI SEO tools safe to use on my website?
It depends on the tool. Look for an approval step, a way to undo, a check on the live page and a record of every change. Those are the limits Arcline is built around.
Can an AI SEO tool improve my Google rankings?
It can fix problems that hold a site back, such as missing titles or broken pages. It cannot promise a position, and results take weeks or months. See how long SEO takes.
Do I still need an SEO specialist?
Many small websites can handle the basics with a good tool. Competitive markets and complex strategy still benefit from an expert. See will AI replace SEO specialists.
What are the best AI SEO tools for a small business?
It depends on whether you need writing, auditing or fixing, and how much time you have. Use the seven questions above to compare them. Arcline has a free plan for one website that reads, scores and prepares fixes, which suits many small businesses.
Does an AI SEO tool help with ChatGPT and AI search?
Some prepare your pages for AI crawlers and check that they can read your site. None can promise a mention. See how AI assistants choose sources.
