Find out what is holding your website back
One report on speed, SEO, AI search, security, site health, and your domain and email, with the fixes that matter most at the top, written in plain English. You do not need to sign up.
What the website report checks
Each area gets a score out of 100, a short summary and the fix for every problem found.
Speed
- Google speed scores for phones and computers
- Core Web Vitals from real Chrome visitors
- Image sizes, caching and files that hold up the page
SEO
- Titles, descriptions and main headings
- Structured data, canonical tags and your sitemap
- How each page looks when shared on WhatsApp or LinkedIn
AI search
- Whether ChatGPT, Claude, Perplexity, Gemini and Copilot can reach your pages
- Your llms.txt and robots.txt
- How clearly your pages answer the questions people ask
Security
- HTTPS and your SSL certificate
- Security headers that protect your visitors
- Software versions with known security holes
Site health
- What the site is built on and how current it is
- Phone set-up, page weight and broken links
- Forms, analytics and tracking set-up
Domain & email
- When your domain expires
- SPF, DMARC and DKIM, which make it much harder for others to send email in your name

Get the fixes in order
Problems first, each with a plain explanation and how to fix it. Share the report link with your team or developer.
Every finding comes with the fix

Is the check free?
Yes. There is no sign-up, and anyone you share a report with can read it. Each connection can run a fair number of checks a day.
Does the check change or slow down my website?
No. Site Signal reads a handful of your pages the way a visitor's browser does. It does not log in, submit forms or try passwords, and nothing on your site is changed.
How accurate are the scores?
The speed scores come straight from Google PageSpeed Insights, so they match what you would see there on the same day. Speed tests vary a little between runs, so run the check again before acting on a borderline score.
Can I share a report?
Yes. Each report has its own link you can send to your team or your web developer. Reports are kept for 30 days and are not listed in search engines.
Who is behind Site Signal?
Site Signal is made by JIN Design, a Singapore web agency that designs, builds and maintains websites. If you want help with anything in your report, you can ask us from the report page.
