Your Website Is Live. But Is It Actually Ready?

Rawan — Sun, 09 Aug 2026 04:55:24 +0000

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.

Try HeronSignal Scan

HeronSignal Scan gives you a fast, actionable view of your public website in just a few minutes. You'll know what's working, what needs attention, and which issue deserves your attention first.
And when you're ready to move beyond identifying problems, every finding can be handed to HeronAgent so you can move from investigation to resolution without leaving the workflow.

Getting Started with HeronSignal: From Installation to Your First AI-Powered Investigation

Rawan — Sat, 01 Aug 2026 00:54:10 +0000

Every production issue starts the same way.

Someone reports that something is broken.

The first thirty minutes aren't spent fixing it. They're spent figuring out what actually happened.

Which users were affected?

When did it start?

Was it the latest deployment?

Can anyone reproduce it?

Monitoring shouldn't stop at telling you something is wrong. It should help you understand why it's happening and give you enough context to fix it.

In this guide, we'll set up HeronSignal from scratch and walk through the features that help you move from detecting an issue to actually resolving it.

Step 1: Connect Your Domain

Before your application can send data, tell HeronSignal which domains belong to your project.
Open Domains from your dashboard and add every origin where your application runs. Most teams will at least add their production and staging environments.
Keeping environments separate makes it much easier to test new releases without mixing test traffic with production data.

Step 2: Install the Tracker

Install the Web SDK.

Create a provider.

"use client";

import { useEffect } from "react";
import { initHeronSignal } from "@heronsignal/web";

export function HeronSignalProvider() {
  useEffect(() => {
    void initHeronSignal({
      publicKey: "YOUR_PUBLIC_KEY",
      service: "storefront",
      environment: "production",
    });
  }, []);

  return null;
}

Mount it inside your root layout.
That's it.
From this point, HeronSignal starts collecting production signals automatically.

Step 3: Verify Everything Is Working

Open your website.
Browse a few pages.
Click buttons.
Fill in a form.
Use the application exactly like one of your users would.
Return to the dashboard.
Within a few moments you should start seeing activity.

What You Can Do Next

Installing the SDK unlocks the platform, but each feature solves a different problem.
Here's a quick tour.

Insights
Need a quick overview of your application's health?
Insights shows visitor activity, page views, and performance trends, with breakdowns by browser, country, and device.
Instead of guessing whether an issue affects everyone or just a subset of users, you can immediately see where the impact is happening.

Sessions
Sometimes a stack trace isn't enough.
Sessions let you replay exactly what a user experienced before an issue occurred.
Instead of asking users how they reproduced a bug, you can watch the journey yourself.

Logger
Logs become much more useful when they're searchable.
Attach structured attributes to your logs.

log("warn", "Checkout retry", {
  step: "payment",
  plan: "pro"
});

Later, search directly for:

@step:payment

@plan:pro

instead of scrolling through hundreds of plain-text messages.

Health Checks
Some pages are too important to fail silently.
Health Checks continuously monitor critical endpoints like your homepage, login page, or checkout.
If something goes down, HeronSignal alerts you.
When it recovers, you'll know that too.

Funnels

Monitoring tells you when something breaks.

Funnels tell you where users stop progressing.

Build journeys such as:

Landing Page
↓
Signup Started

↓
Signup Completed

event("landing_page_viewed");

event("signup_started");

event("signup_completed", {
  plan: "pro"
});

You'll immediately see conversion rates, drop-off points, and trends over time.

AI Analysis
Once production data starts flowing, AI Analysis helps prioritize what deserves attention first.
Instead of looking through every dashboard yourself, AI reviews the available signals and surfaces the issues with the greatest impact.
For example, it might highlight:
LCP regression on the pricing page
Checkout failures
Slow cart API responses
Helping you decide where to begin instead of where to click next.

Connect Your Coding Agent
When you're debugging a production issue, one of the biggest frustrations is giving your AI assistant enough context.

You copy an error message, paste a stack trace, explain what the user experienced, attach screenshots, and hope it has enough information to help.

With HeronSignal's MCP integration, your coding agent can access live production context directly.

Instead of working from code alone, tools like Cursor, Claude, or Codex can understand what's happening in your application while helping you investigate an issue.

Connecting your coding agent only takes a few minutes. Create an MCP token from your HeronSignal dashboard, then add it to your AI client.

{
  "HeronSignal": {
    "url": "https://api.heronsignal.com/mcp?workspaceId=YOUR_WORKSPACE_ID",
    "headers": {
      "Authorization": "Bearer paste-token-shown-once"
    }
  }
}

By default, MCP tokens are read-only, allowing your coding agent to safely inspect production context without modifying anything.

If you want your agent to help create Funnels, you can enable Funnel write permissions when generating the token.

Complete the Setup
Before you finish, make sure you've completed these final steps:

Add every production and staging domain from Domains.
Visit your website and interact with it like a real user.
Return to the dashboard and verify that data is appearing in Insights, Sessions, Logger, Funnels, and AI Analysis.
At this point, your HeronSignal setup is complete.

Imagine a customer reports that checkout feels slower than usual.

You open Insights and notice a performance regression.
A Session Replay shows exactly what the customer experienced.
Logger helps you search related logs using structured attributes.
AI Analysis highlights the issue affecting the most users, and your coding agent already has the production context needed to investigate further.

That's the workflow you've just built.

From installation to investigation, HeronSignal gives your team the visibility and context needed to understand production faster and spend more time solving problems.
