What the check covers

More than 30 checks for Google and AI

Crawling and indexing

5

Can Google find and properly index the page?

  • HTTPS and redirect
  • Canonical tag
  • XML sitemap
  • Number of redirects
  • Page language
See why these checks matter
HTTPS and redirect
A secure connection is a signal for Google and builds trust. The http version should redirect to https automatically.
Canonical tag
The canonical tells Google which URL is the real version of the page, so variants with parameters or without a slash do not compete.
XML sitemap
A sitemap helps search engines find all pages. Reference it in robots.txt and submit it in Google Search Console.
Number of redirects
Every redirect costs loading time. A link should reach the right page in one step.
Page language
The lang attribute tells search engines and screen readers the language of the page. With several languages, hreflang helps Google show the right version.

Technical and mobile

3

Is the page secure and does it work well on a phone?

  • Mobile friendly
  • No insecure files
  • HSTS header
See why these checks matter
Mobile friendly
Google assesses the mobile version of your site. Without a viewport setting, the page is shown zoomed out on a phone.
No insecure files
Images or scripts over http on an https page are blocked or flagged as insecure by browsers.
HSTS header
With HSTS a browser remembers that your site is only reachable over https. A small, tidy security step.

Speed

4

How fast does the page load on mobile? Measured with Google PageSpeed Insights.

  • Mobile performance score
  • Content loading time (LCP)
  • Layout shift (CLS)
  • Responsiveness (INP)
See why these checks matter
Mobile performance score
The Google Lighthouse performance score, from 0 to 100, shows how fast the page loads on an average phone.
Content loading time (LCP)
LCP measures how long it takes for the largest piece of content to appear. Google wants under 2.5 seconds. It is one of the Core Web Vitals.
Layout shift (CLS)
CLS measures how much the page shifts while loading. Google wants under 0.1. It is one of the Core Web Vitals.
Responsiveness (INP)
INP measures how quickly the page responds to taps and clicks, with real Chrome visitors. Google wants under 200 milliseconds. It is one of the Core Web Vitals.

On-page

8

Are title, description, headings, images and links in order?

  • Title length
  • Meta description length
  • Heading structure
  • Image alt text
  • Internal links
  • Shareable on social media
  • Readable URL
  • Privacy policy linked
See why these checks matter
Title length
Google shows about 50 to 60 characters of the title. A title of 30 to 60 characters with the main keyword first works best.
Meta description length
The meta description is often the text under your title in Google. Between 70 and 160 characters it fits and shows why someone should click.
Heading structure
Headings in logical order, H1 then H2 then H3, make the structure clear for search engines and screen readers.
Image alt text
Alt text describes images for search engines and for people using a screen reader.
Internal links
Internal links help search engines find your other pages and show which pages matter.
Shareable on social media
Open Graph tags decide how a link looks on LinkedIn, Facebook and WhatsApp: title, text and image.
Readable URL
A short URL in lowercase with hyphens is easy to read and share, and shows what the page is about.
Privacy policy linked
A findable privacy policy is required when you process personal data, and a sign of trust.

AI visibility (GEO) 11

Access

2

Can AI search engines read and use the page?

  • AI search bots in robots.txt
  • Indexable, snippet allowed
  • Firewall or CDN
See why these checks matter
AI search bots in robots.txt
OAI-SearchBot (ChatGPT), PerplexityBot and Claude-SearchBot must be allowed to read the page. If you block OAI-SearchBot, ChatGPT search will not show the site. Blocking training bots such as GPTBot is fine; it does not remove you from the answers.
Indexable, snippet allowed
Google AI Overviews only use pages that are indexed and allowed to show a snippet. A noindex, nosnippet or very short max-snippet keeps the page out of AI answers.
Firewall or CDN
A robots.txt that allows everything does not help if a firewall or CDN stops AI bots.

Content

6

Can an AI search engine get a useful answer from it?

  • Text without JavaScript
  • Title and meta description
  • One clear H1
  • Answer first
  • Headings as questions
  • Publication or update date
See why these checks matter
Text without JavaScript
Many AI crawlers run little or no JavaScript. Text that only appears after JavaScript is often not read. The scan counts the words that are directly in the HTML.
Title and meta description
The title and meta description tell search engines in a few words what the page is about.
One clear H1
The H1 is the main heading of the page. One clear H1 shows at a glance what the page is about.
Answer first
AI search engines often take their citations from the start of a text. In an analysis by Kevin Indig, 44.2% of ChatGPT citations came from the first 30% of the text. A short paragraph that answers directly helps.
Headings as questions
People ask AI search engines questions. Headings phrased as questions make it easy to find the matching answer.
Publication or update date
AI assistants cite newer pages on average than Google. A visible date, also in the code, shows the content is current.

Organisation

3

Is it clear who is behind the site?

  • Organisation in schema markup
  • Profiles elsewhere (sameAs)
  • About and contact linked
See why these checks matter
Organisation in schema markup
Organization or LocalBusiness schema tells search engines who the business is: name, address, logo and profiles.
Profiles elsewhere (sameAs)
sameAs in the schema links the site to profiles such as LinkedIn and the Google Business Profile. That helps recognise the business across sources.
About and contact linked
An about and a contact page show who is behind the site. For people and search engines that is a sign of trust.

SEO check or SEO audit?

What a website SEO check is and is not

An SEO check is a quick test of one page on the technical and content points that decide whether Google and AI search engines can find, read and show the page well. In half a minute you see what is wrong and what to fix first.

An SEO audit goes further: a specialist reviews the whole site, keywords, competition, backlinks and Search Console data, and turns that into a strategy. A check is the start, not a replacement for an audit.

Run the check after every major change to a page and at least once a quarter for your most important pages. For clients it works best as a fixed monthly measurement.

What the check does not do

Honest about the limits

  • It does not measure whether ChatGPT mentions you

    The scan looks at the page itself. Whether an AI search engine mentions your business on its own also depends on mentions elsewhere. You measure that with fixed questions, or with the AI Rank Analyzer.

  • It does not count llms.txt

    Google says you do not need llms.txt or other AI files, and research by SE Ranking found no effect on how often a site is cited.

  • It sets no minimum word count

    Google says you do not need to write in a special way for AI. The scan only counts words to see whether the text is readable without JavaScript.

  • It checks one page

    Also check your most important service pages, not just the homepage. A crawl of the whole site, backlinks, rankings and keywords are not included.

Frequently asked questions

Questions about the SEO check

What does the free SEO check cover?

The check looks at one page on more than 30 points: crawling and indexing (https, canonical, sitemap), technical and mobile, speed via Google PageSpeed Insights, on-page (title, meta description, headings, alt text, links) and AI visibility (access for AI bots, text without JavaScript, answer first, organisation schema).

What is the difference between an SEO check and an SEO audit?

An SEO check automatically tests one page on technical and content points and shows right away what is wrong. An SEO audit is broader: a specialist reviews the whole site, keywords, competition, backlinks and Search Console data and turns it into a strategy.

How often should I run an SEO check?

After every major change to a page, and at least once a quarter for your most important pages. For clients a fixed monthly measurement works best.

What is a GEO scan?

A GEO scan checks whether a web page is ready to be used and mentioned by AI search engines such as ChatGPT, Perplexity and Google AI Overviews. In the Nekx SEO check that is the GEO part, with its own score.

Is the SEO check free?

Yes. The check is free and you do not need to sign up. The result appears right on the page, and you can download it as a report with your own logo.

What do the SEO score and GEO score mean?

Both scores run from 0 to 100 and weight each check by importance. The SEO score is about visibility in Google, the GEO score about AI search engines. A high score means the page is technically in order; your Google position and whether AI search engines mention you also depend on competition and mentions elsewhere.

Do I need to allow GPTBot to appear in ChatGPT?

No. According to OpenAI, GPTBot is only for training. ChatGPT search uses OAI-SearchBot. That is why the scan checks the search bots, not the training bots.

Do you store my data?

We keep the checked address and the scores to improve the check, but no data about you. Your logo stays on your device. We only store your agency name and email address if you tick the box at the report saying we may contact you.

Can I use the check for client sites?

Yes. Download the result as a report with your agency’s logo and colour; Nekx SEO is not mentioned. If you want to measure and improve your clients’ visibility every month, Nekx SEO does that under your own name.
