Deploying a website is the easy part. Knowing whether it's actually ready for the public is much harder.
The application loads. Your health checks are green. There are no obvious errors in production. Everything looks fine until someone notices your site isn't appearing in search results, a page isn't being indexed, or AI assistants can't understand your documentation.
None of these problems usually trigger an alert. They quietly reduce discoverability, hurt traffic, and make it harder for people, and increasingly AI systems, to find and understand what you've built. By the time someone notices, they've often existed for days or even weeks.
That's why we built HeronSignal Scan.
Scan analyzes your public website from the outside and shows you how ready it is for visitors, search engines, and AI systems in just a few minutes. Instead of waiting for users to discover problems, you can find them before they affect traffic, visibility, or customer experience.
Check your website from the outside
When you work on a website every day, it's easy to assume everything is working as expected. Visitors, search engines, and AI systems don't see your application the way you do. They only see what your public website exposes.
HeronSignal Scan gives you that outside perspective. Simply enter your website URL and start the scan. A few minutes later, you'll have a report showing how your website appears to the systems responsible for discovering, indexing, sharing, and understanding your content.
Whether you're launching a new product, publishing documentation, updating a marketing site, or reviewing changes after a deployment, Scan gives you an objective view of your website without requiring any setup.
What does Scan actually check?
A website can appear to work while still having issues that affect discoverability, performance, and user experience.
Scan organizes its findings into six categories.
Availability: Can visitors reach your website?
SEO & AI Readiness: Is your website exposing the signals modern search engines and AI systems rely on?
Crawler & AI Search: Can search engines and AI crawlers access your public content?
Metadata & Sharing: Does your website expose the metadata needed for search results and rich previews?
Public Speed Estimate: A first look at response speed from an external scan. Measuring real visitor performance requires the HeronSignal tracker.
Monitoring Readiness: Shows what a public scan cannot observe and what becomes available once HeronSignal is installed, such as real user behavior, frontend events, logs, and production investigations.
Rather than producing a long technical report, Scan summarizes the results into clear categories, highlights your weakest area, and prioritizes the most important issue so you immediately know where to begin.
Start with what matters most
One of the biggest frustrations with website auditing tools is information overload. Many generate hundreds of warnings without telling you which ones actually deserve your attention.
Scan takes a different approach. Instead of overwhelming you with raw technical output, it highlights the issue that deserves your attention first.
For example, when we scanned LockerRoomors, the highest priority finding wasn't a generic SEO warning. It was AI friendly public signals need attention.
The report immediately explained why.
AI crawlers are allowed.
Structured data is present.
Readable HTML is available.
The sitemap is configured correctly.
An llms.txt file hasn't been detected.
Within a few minutes, you know what's already configured correctly, what's missing, and what should be addressed first. Instead of spending time interpreting reports, you can focus on solving the right problem.
Every recommendation includes context
A warning is only useful if you understand why it matters.
Every recommendation explains what was checked, what was found, and why the result affects your website.
Take AI readiness as an example. More teams are asking whether AI assistants can understand their documentation, whether AI powered search engines can discover their products, and whether they're exposing the right public signals.
If something is missing, Scan doesn't simply mark it as a failure. It explains exactly what could improve your website, whether that's exposing readable HTML, adding structured data, allowing AI crawlers, or adding an llms.txt file.
Instead of searching documentation to understand a recommendation, the explanation is already part of the report.
Scan is only the beginning
Most website auditing tools stop once they've generated a report. They identify the problem, then leave the implementation to you.
HeronSignal takes the next step.
Every finding includes a Fix button that hands the issue to HeronAgent. HeronAgent investigates what needs to change and, just as importantly, where that change belongs.
Sometimes the solution is in your application's codebase. Other times it's a CDN configuration, a robots.txt rule, a DNS record, or another part of your infrastructure. Rather than assuming every issue belongs in your repository, HeronAgent determines the right place to make the change, generates the change, and brings it back for your review.
That's what makes Scan different from traditional website auditing tools. It doesn't stop at identifying problems. It helps you move toward fixing them.
Run a scan whenever your website changes
Every deployment changes something. Most changes are intentional, but some introduce subtle regressions that nobody notices immediately. A sitemap disappears, metadata is removed, crawler rules change, search visibility drops, or AI readiness regresses.
Running a scan after every meaningful change gives you confidence that your public website is still ready for visitors, search engines, and AI systems before those small issues become larger ones.
You can run a free scan anytime at heronsignal.com/scan.
Build for people and for the systems that help them find you
Today's websites have more than one audience.
You're building for people, but you're also building for search engines, AI assistants, answer engines, and other crawlers that help people discover your content.
Each of these systems relies on public signals to understand your website. Scan helps verify that those signals are present and correctly configured, making it easier for your website to be discovered, indexed, understood, and shared.
It's not just about finding technical issues. It's about making sure your website is ready for everyone who interacts with it.
