How to use the Hostinger AI Visibility Checker

The Hostinger AI Visibility Checker is a free tool that scans your website the way an AI agent does and gives it an AI readiness score out of 100. It shows whether AI tools such as ChatGPT, Claude, and Perplexity can access and read your site. It doesn’t track whether AI answers mention your brand. To use it, run a scan, read your score and grade, review each check, and copy the fix instructions for the issues found.

Before you start

The AI Visibility Checker reads your homepage, robots.txt, sitemap, and llms.txt file.
The scan reads public content only and doesn’t change anything on your website.

Run a scan with the Hostinger AI Visibility Checker

Enter your domain on the AI Visibility Checker page to start a scan:

Open the Hostinger AI Visibility Checker page.
Enter your domain, for example domain.tld, in the URL field.
Click Scan site.

The results page shows your domain and the date and time of the scan next to Last scanned.

Understand your AI readiness score and grade

Your AI readiness score is a number from 0 to 100, shown with a letter grade and a status. For example, a score of 40 receives Grade D and the status Not agent-ready yet.

The score is the total of seven categories. Each category shows the points earned out of the maximum, and a circle with the result as a percentage. For example, 13 out of 20 points in Crawl permission shows as 65.

Category

Maximum points

What it checks

Crawl permission

Whether a readable robots.txt file exists, whether AI crawlers are blocked by robots.txt or bot detection, and whether Content Signals are declared.

Findability

Whether a sitemap exists, is declared in robots.txt, and has recent update dates, whether missing pages return a 404 error, and whether the homepage loads over HTTPS.

Readability

Whether content is readable without JavaScript, the page size is reasonable, the title, meta description, and canonical tags are present, and headings follow a clear order.

Structured meaning

Whether the homepage has JSON-LD structured data describing your business, links to your external profiles, and several schema types.

Commercial legibility

Whether about, contact, and legal pages are linked, contact details are machine-readable, and prices are reachable without JavaScript or login.

Agent-native content

Whether a valid llms.txt file is served, the site returns Markdown when an AI agent requests it, and the homepage lists resources in Link headers.

Agent interaction

Whether the site exposes WebMCP tools to in-browser AI agents and publishes an MCP Server Card.

Review each check and its fix

Each category lists its individual checks, with the points earned for each one. A check has one of three results:

Passed – a green check mark with full points.
Failed – a red cross with zero or partial points, for example 3/4 pts.
Not checked – the check depends on something missing. For example, sitemap update dates aren’t checked when no sitemap exists.

Click a check to expand it:

What we found describes the result. For example, /llms.txt returned HTTP 404.
How to fix explains the change needed. Failed checks only.
Copy prompt copies the fix instructions for that check, ready to paste into an AI coding assistant.

Copy all fixes with Improve score

Use Improve score to copy the instructions for every issue at once:

Click Improve score below the category results.
Review the How to improve your score window. It lists the goal, issue, and fix for each failed check, and the total number of issues found.
Click Copy instructions.
Paste the instructions into your AI coding assistant to apply the fixes.

Fix common AI visibility issues on Hostinger

Several common issues have step-by-step fixes for Hostinger websites:

robots.txt and AI crawlers – allow or block AI crawlers on your Hostinger website. On web and cloud hosting, you can also edit website files using the Hostinger File Editor.
llms.txt – enable LLMs.txt on your WordPress or Hostinger AI Builder manual mode website. Hostinger AI Builder agentic mode creates an llms.txt file automatically when you publish, as explained in Hostinger AI Builder: GEO settings in agentic mode.
Bot detection – see Hostinger CDN: Search engine crawlers and SEO for the CDN settings that can block crawlers, such as Under Attack mode and blocked bots.
Sitemap – see Hostinger AI Builder: How to submit website sitemap for sitemap details on Hostinger AI Builder websites.
Meta description and headings – on Hostinger AI Builder manual mode websites, add meta titles and descriptions and use heading tags for SEO. For agentic mode websites, see Hostinger AI Builder: SEO settings in agentic mode.
AI agent access – Web2Agent in Hostinger makes WordPress and Hostinger AI Builder manual mode websites accessible to AI agents.

Run a new scan after making changes to confirm the fixed checks now pass.

After the scan, you know which checks block AI tools from reading your website and how to fix each one. Each fixed issue raises your AI readiness score.
