Fix Google Search Console Errors Before They Kill Your Launch

Google Search Console is where launches go to die quietly. You deploy your site, submit your sitemap, and wait for traffic. Two weeks later you check GSC and find a wall of red: "Page with redirect," "Duplicate without user-selected canonical," "Redirect error." Your pages are not indexed. Your launch window is closing. And the error messages are cryptic enough that you are not sure what to fix first.

These errors are predictable. They follow the same patterns on every platform — Netlify, Vercel, Cloudflare Pages, GitHub Pages. The Digital Empire Analyzer's Hosting & Indexing Health quick action detects them automatically so you can fix them before GSC ever sees them.

The Three Errors That Kill Launches

1. Page with Redirect

This means Google found a URL in your sitemap or internal links that redirects to a different URL. Google does not want to index the redirect — it wants the final destination. But if your sitemap contains the wrong version, Google flags every page.

The most common cause: your site serves both http:// and https://, or both www and non-www, and your sitemap references the version that redirects.

2. Duplicate, Google Selected Canonical

Google found two versions of the same page and picked one. You did not tell it which to prefer using a canonical tag, so Google guessed. Sometimes it guesses wrong and indexes the version with query parameters or a trailing slash instead of your clean URL.

3. Redirect Error

A redirect loop or chain. URL A redirects to URL B, which redirects back to URL A. Or A redirects to B, B to C, C to D — and Google gives up after too many hops. This is almost always caused by conflicting redirect rules between your DNS provider and your hosting platform.

How the Hosting Health Quick Action Detects These

In the Digital Empire Analyzer, after your main scan completes, click the Hosting & Indexing Health quick action. It runs a separate set of checks focused specifically on the infrastructure layer:

• Resolves both www and non-www versions of your domain and checks whether one redirects to the other cleanly.
• Checks for redirect chains (more than one hop) and redirect loops.
• Verifies your canonical tag matches the URL that actually resolves.
• Tests both HTTP and HTTPS versions to confirm the upgrade redirect works.
• Checks HSTS headers to see if the browser-level HTTPS enforcement is in place.
• Detects /index.html duplicate content (one of the most common static site issues).

Every detected issue appears with a severity rating and a fix description. For issues that need platform-specific code, there is the LLM Fix Prompt button — more on that below.

www vs non-www: Pick One and Enforce It

This is the single most common cause of GSC redirect errors on new sites. You need to decide: is your site www.example.com or example.com? Both will work, but both cannot be the canonical version.

On Netlify, add a _redirects file in your publish directory:

# If you chose non-www as canonical:
https://www.example.com/* https://example.com/:splat 301!

Or configure it in netlify.toml:

[[redirects]]
  from = "https://www.example.com/*"
  to = "https://example.com/:splat"
  status = 301
  force = true

On Vercel, add to your vercel.json:

{
  "redirects": [
    {
      "source": "/:path(.*)",
      "has": [{ "type": "host", "value": "www.example.com" }],
      "destination": "https://example.com/:path",
      "permanent": true
    }
  ]
}

On Cloudflare, create a redirect rule in the dashboard or use a _redirects file if you are on Cloudflare Pages:

https://www.example.com/* https://example.com/:splat 301

For Cloudflare with a proxy (orange cloud), you can also use a Page Rule:

Match: www.example.com/*
Setting: Forwarding URL (301)
Destination: https://example.com/$1

After setting up the redirect, update your DNS. If you chose non-www, your www CNAME should point to your hosting provider so the redirect can fire. If you chose www, your apex domain needs a redirect — Cloudflare handles this natively, but Netlify and Vercel require DNS-level configuration.

The /index.html Duplicate Fix

Static site generators like Eleventy, Hugo, and Astro often output about/index.html for a page at /about/. This means both /about/ and /about/index.html resolve to the same content. Google sees two pages and flags one as a duplicate.

The fix depends on your host:

Netlify handles this automatically — /about/index.html redirects to /about/ with a 301. No action needed if you are using Netlify's built-in pretty URLs.

Vercel also strips index.html by default with the cleanUrls option:

{
  "cleanUrls": true
}

Cloudflare Pages strips index.html automatically. If you are using Cloudflare with a custom server or Workers, add the redirect explicitly:

// In a Cloudflare Worker
if (url.pathname.endsWith('/index.html')) {
  const clean = url.pathname.replace(/\/index\.html$/, '/');
  return Response.redirect(new URL(clean, url.origin), 301);
}

Also make sure your canonical tags reference the clean URL, not the index.html version:

<!-- Correct -->
<link rel="canonical" href="https://example.com/about/">

<!-- Wrong — will cause duplicate canonical errors -->
<link rel="canonical" href="https://example.com/about/index.html">

HSTS Headers and Why They Matter

HSTS (HTTP Strict Transport Security) tells browsers to always use HTTPS for your domain, even if a user types http:// or clicks an old HTTP link. Without HSTS, every first visit to the HTTP version triggers a server-side redirect, which adds latency and creates another URL variant for Google to track.

Add this header to your server response:

Strict-Transport-Security: max-age=31536000; includeSubDomains; preload

On Netlify, add it to your _headers file:

/*
  Strict-Transport-Security: max-age=31536000; includeSubDomains; preload

On Vercel, add it to vercel.json:

{
  "headers": [
    {
      "source": "/(.*)",
      "headers": [
        {
          "key": "Strict-Transport-Security",
          "value": "max-age=31536000; includeSubDomains; preload"
        }
      ]
    }
  ]
}

On Cloudflare, HSTS is a toggle in the SSL/TLS settings. Enable it and set max-age to at least one year.

The preload directive qualifies your domain for the HSTS preload list, which is hardcoded into Chrome, Firefox, Safari, and Edge. Once you are on it, browsers will never even attempt an HTTP connection to your domain. Submit at hstspreload.org after you confirm the header is working.

The LLM Fix Prompt Feature

Some issues need more context than a one-line code snippet can provide. The Hosting Health results include a Copy LLM Fix Prompt button that generates a detailed prompt containing:

• Your domain and hosting platform (auto-detected when possible)
• Every detected issue with severity and description
• Your current DNS configuration and redirect behavior
• The specific GSC error patterns you are likely to encounter

Paste this prompt into ChatGPT or Claude and you get back platform-specific fixes organized by priority, with file paths, code blocks, and deployment steps. This is the same workflow described in Chapter 41 of The $97 Launch — using AI as a precision code generation tool rather than a general-purpose chatbot.

The prompt is structured so the model knows your exact stack. Instead of getting generic "add a redirect" advice, you get the exact netlify.toml block or vercel.json entry for your situation.

Where to Learn More

The checks in the Hosting Health action map directly to material in the book trilogy:

• The $20 Dollar Agency Chapter 4 covers the Technical SEO Files — robots.txt, sitemaps, canonical strategy, and the redirect rules that prevent every issue described in this post.
• The $100 Network Chapter 17 covers the Indexing Stack — IndexNow, search engine submission, and the monitoring workflow for catching GSC errors before they accumulate.

Both assume a $97 budget and a solo founder doing their own technical work.

Run the Check Before Google Does

Go to jwatte.com/tools/analyzer, enter your URL, and click the Hosting & Indexing Health quick action. Fix what it finds. Then check Google Search Console in a week with confidence instead of dread. The errors that kill launches are the ones you could have caught in 30 seconds — if you had looked.
