Shopify 404 Errors Are Killing Your Traffic. Here’s What Actually Fixes Them.

Every Shopify store owner faces this at some point.

You update your product catalog, rename a collection, delete an old page. And somewhere out there, an old link in a Google search result, a customer email, or a social media post now leads to a dead end.

A “Page Not Found” error.

I’ve seen this happen across hundreds of stores. And in most cases, the merchant had no idea it was happening or how much traffic they were losing because of it.

Here’s what I found that actually works.

What Is a 404 Error?

A 404 error happens when a visitor’s browser requests a page from your server and the server simply can’t find it. The page either no longer exists, the URL changed, or someone typed the wrong address.

It’s not a server problem. Your store is still up and running fine. The issue is with the specific URL being requested.

The 4xx Errors You Need to Know About

Not all errors are the same. Here’s a quick breakdown of the most common ones:

• 404 (Not Found) -> The page can’t be found. It may have moved, been deleted, or the URL was typed wrong.
• 410 (Gone) -> The page has been permanently deleted and is not coming back. Use this when you’ve discontinued a product for good.
• 403 (Forbidden) -> The page exists but the visitor doesn’t have permission to view it.

The difference between 404 and 410 matters for SEO. A 410 tells search engines to remove the page from their index right away. A 404 tells them it might come back.

Use the right one depending on your situation.

What Causes 404 Errors on Shopify?

The most common reasons I see across stores:

• A product or collection page was deleted without setting up a redirect
• The URL structure was changed and old links weren’t updated
• A product variant like a specific size or colour is no longer available, but the URL still gets traffic
• Old blog posts or campaign landing pages that were removed
• Platform migrations where the old URL structure didn’t carry over properly

Any of these can quietly bleed traffic without you realising.

The Silent One: Soft 404 Errors

This one catches a lot of store owners off guard.

A soft 404 happens when a page that doesn’t really exist returns a 200 OK status code instead of a proper 404. The page loads. It looks fine on the surface. But the content is essentially empty or useless.

Google flags these and wastes crawl budget indexing pages that offer no value.

Soft 404s happen on Shopify when:

• A product sells out and the page shows no results
• A collection is filtered down to zero products
• A variant URL for a discontinued size or colour is still accessible
• An internal search results page with no matching products gets indexed

These don’t throw an obvious error so they’re easy to miss. But they hurt your SEO the same way a regular 404 does.

Why You Should Fix These Quickly

Most store owners treat 404 errors as a minor issue. In my experience, they’re not.

Every broken link is a lost visitor. Someone clicked expecting to find a product and hit a wall. Most of them don’t look for an alternative. They just leave.

For SEO, old pages that used to rank can hold real link equity. When those pages 404, that equity disappears. Search engines that keep hitting dead ends on your store start crawling it less frequently.

And for paid campaigns, if an ad is pointing to a URL that no longer exists, you’re spending money sending people to nothing.

The Tool That Changed How I Handle This

After testing a lot of approaches across different stores, the one that consistently worked best was SC Easy Redirects and specifically its AI Redirects feature.

Here’s how it works in simple terms.

When a visitor hits a 404 on your store, the app doesn’t just log the error and wait for you to fix it. The AI scans your current catalog, finds the most relevant live page, and calculates a confidence score for the match.

If the confidence is high enough, it automatically creates a 301 redirect right then and there. The next visitor who clicks that broken link lands on a working product page without ever knowing anything was wrong.

How to Set It Up

This is genuinely straightforward. Here’s how I set it up on stores.

Step 1: Install SC Easy Redirects

Go to the Shopify App Store and install the app. The onboarding walks you through the basics quickly.

Step 2: Configure Your Confidence Threshold

This is the most important setting. The threshold determines when the AI creates a redirect automatically vs. when it sends a match to your manual review queue.

I usually start stores at 85% or higher. That way only very confident matches go live automatically. Lower-confidence suggestions sit in a queue for you to review and approve.

Step 3: Set a Fallback Destination

For cases where no good match exists at all, you set a fallback page. Usually your homepage or main collection page. This means no visitor ever lands on a completely dead end.

Step 4: Test It

Type a made-up URL on your store and watch what happens. High-confidence matches redirect immediately. Lower ones queue up for review. Once you see it working, you can leave it running in the background.

Step 5: Check In Monthly

The setup does most of the work on its own. But once a month, I recommend reviewing the manual queue and checking the redirect logs. It takes about ten minutes and keeps everything clean.

What I Noticed Across Stores After Using This

The results were consistent across stores I set this up on.

Bounce rates on 404 pages dropped significantly. Traffic that was previously disappearing into broken URLs started flowing to relevant product pages. And the stores that were running SEO campaigns stopped losing link equity every time they made catalog changes.

The biggest win was time. What used to be a manual process that could eat up a full day was now running quietly in the background without anyone touching it.

A Few Tips From Experience

• Keep your confidence threshold high when you first set it up. You can always lower it later once you trust the matching accuracy.
• Point your fallback to a high-converting page, not just your homepage. A bestsellers collection or a main category page tends to work better.
• Avoid creating redirect chains. If you redirect A to B and then later redirect B to C, always update the old redirect to point directly to the final destination.
• Clean your review queue regularly. Lower-confidence matches pile up over time if you ignore them.
• For soft 404s, the best fix is either adding a proper 404 redirect or improving the page content so it has actual value. Don’t leave empty pages indexed.
