AUDITby nfw.run

Free SEO audit: the SEO checker for Google and for AI search.

Enter the address: we audit the site's SEO starting from its homepage, measure it with Lighthouse, check whether ChatGPT and the other AI assistants can read it, and compare the results with the business websites we scanned in your city. Every audit gets its own page, with its date and time, and you can run it again to see how the site changes.

Free, up to 5 different websites an hour. No sign up. We audit the site's homepage.

Some firewalls and bot protections (Cloudflare, Vercel and the like) block automated scans: if the results look odd or partial, that is almost always why.

// what the report holds

What the audit shows

  • The fixes that matter most

    At the top of the report, in order of importance: what to fix first and how, in plain words.

  • Lighthouse scores

    Performance, accessibility, best practices and SEO of the homepage, measured by simulating a mid range phone on a slow mobile connection.

  • Core Web Vitals

    LCP, FCP, TTFB and CLS: how soon the page shows up, how fast the server answers and how steady the page stays while it loads.

  • Homepage SEO checks

    Title, meta description, canonical, structured data, Open Graph, headings, HTTP errors and soft 404s.

  • Domain and server

    HTTPS, HTTP to HTTPS redirect, www consistency, robots.txt, XML sitemap, llms.txt, Search Console and the server's IP on spam blocklists.

  • AI visibility

    The AI score: how ready the site is to be read and cited by ChatGPT, Gemini, Perplexity and the other AI assistants, llms.txt and AI crawlers included.

  • Compared with your city

    Every score next to the business websites we scanned in your city, or the national average.

  • One page per audit

    With its date and time, linked to the earlier and later audits of the same site: audit again after a change and compare.

// frequently asked questions

SEO, email, speed and AI:
the short answers.

An SEO audit checks everything that can hold a site back in search results. Our analyzer reads the site's homepage and checks its title, meta description, canonical, structured data, social preview, headings, errors, robots.txt, the sitemap, llms.txt, HTTPS and redirects, then measures it with Lighthouse.
Yes, with no sign up and no card. You can scan up to 5 different websites an hour, and audit the same site again after 10 minutes: before that we show you the audit already made. Every audit keeps its own page, so you can compare them over time.
Usually a few minutes. Public scans start in order of arrival and give way to the studio's own work, so while you wait you see your place in line and an estimated time that updates on its own. You can also close the page and get the report by email.
Lighthouse scores SEO from 0 to 100: 90 and above is good, 50 to 89 needs improvement, below 50 is poor. It is a technical check, not a ranking prediction: a site can score 100 and stay invisible if its content does not answer what people are searching for.
They are lab measurements: Lighthouse loads the homepage as a mid range phone on a slow mobile network. By Google's measure, Largest Contentful Paint is good within 2.5 seconds and layout stability (CLS) within 0.1. Interactivity (INP) can only be measured on real users, so it is not shown.
It measures how ready the site is to be read and cited by ChatGPT, Perplexity, Gemini and Google's AI answers. It is a weighted mean of ten checks: content readable without JavaScript, llms.txt, robots.txt open to AI crawlers, structured data, sitemap, title, meta description, canonical, HTTPS and SEO score. A check we cannot verify never lowers the score.
Yes, on the technical side. Generative engine optimization (GEO), or AI search optimization, is SEO for AI answers: before an assistant can cite a site, it has to be able to read it. The AI score checks exactly that, through llms.txt, AI crawlers and structured data. Being cited then depends on content, which the audit does not judge.
With the business websites of a city we scanned for the State of the Web, or with the national average. For every measure we tell you how many of those sites yours does better than, and what the median value is. You pick the city to compare with.
Almost always because of a firewall or bot protection, such as Cloudflare's or Vercel's: it blocks automated visits, so the scan reads a checkpoint page instead of the site. When we notice it we show no scores. If the site is yours you can let the scanner through, or write to us and we will look at it.
Yes. Every audit has its own public page, and for each site the latest successful audit can appear on Google. Write to audits@nfw.run from an address on the domain, or tell us how to check the site is yours: we remove its audits and, if you like, make sure it is not scanned again.
The email is optional: we only use it if you accept both the privacy policy and marketing communications, and we send you the report. You can unsubscribe from every email. Every audit has its own page; your browser keeps only a reference to your latest audits, to reopen them.

The report says something's off.
We can fix it.

SEO errors, slow pages, sites invisible to AI: these are exactly the problems we solve for small and medium businesses every day.
