In short
This free website scanner gives any site an instant health check. Enter a URL and it grades five areas: availability, SSL, security headers, SEO essentials, and social sharing. You get a score from A to F and a clear list of what passed, what to improve, and what is failing. It runs in your browser in seconds, with no signup. Scan your own site or a competitor.
- Grades SSL, security headers, SEO, and social tags.
- Plain-language fixes for every problem found.
- Free, no signup, results in seconds.
What the scanner looks at
The scanner runs the same checks a security and SEO professional would run first, and it does them in one pass. It confirms the site loads and how fast it responds. It reads the SSL certificate to confirm it is valid and not about to expire. It looks for the security headers that protect visitors from common attacks. It reads the page for the title, description, headings, and sharing tags that decide how the site shows up in search and on social media. Then it grades each area so you can see your weak spots at a glance.
Why these checks matter for your business
A slow or insecure site costs you visitors and trust. A missing meta description or a broken heading structure costs you search traffic. Most small business sites lose points here without anyone noticing, because the page builder never set these things up. The report turns those hidden problems into a short to-do list, written in plain language, so you know what to fix first and why it matters.
Fixing one setting at a time is slow. The faster path is a platform that handles your site, security, and marketing together. That is what GoHighLevel does, and it is what our free community helps you set up.

Frequently asked questions
What does the website scanner check?
It runs over 25 checks in one pass. Server response and speed, server location, IP and hosting, the SSL certificate, security headers, HSTS, DNS records, TXT records, email security (SPF and DMARC), the redirect chain, HTTP headers, cookies, tech stack, firewall detection, SEO tags, social tags, crawl rules, page quality, carbon footprint, domain WHOIS, DNSSEC, security.txt, archive history, linked pages, open ports, and a homepage screenshot. You get a grade from A to F and a list of what passed, what to improve, and what is failing.
Is the website scanner free?
Yes. It is free, needs no signup, and runs in seconds. Enter any public website address and you get the full report. You can scan your own site or a competitor site.
Does scanning a site harm it or get me blocked?
No. The scanner only reads public information the way a normal browser does. It loads the homepage once, reads the response headers, checks the certificate, and looks up public DNS records. It does not log in, attack, or overload anything.
Why does my site get a low grade?
Most sites lose points on security headers and SEO tags, because page builders do not set them by default. Missing HSTS, no Content-Security-Policy, a missing meta description, or no Open Graph image are common. Each item in the report explains what it means and why it matters, so you know exactly what to fix.
How do I fix the problems the scanner finds?
Some fixes are settings in your host or page builder. Others need a platform that handles your site, security, and SEO together. GoHighLevel runs all of it from one login, and our free community will walk you through the setup. You can start a free 30-day trial and bring your report with you.
