How Broken Links Silently Cost Your eCommerce Store Traffic and Sales

A broken link is a dead end. A shopper clicks on a product recommendation, a collection link, or an internal navigation element — and instead of arriving at a product page, they see a 404 error. The sale is lost, and so is a bit of their trust in your store.

But the visible customer impact is only half the story. Broken links also silently erode your SEO performance in ways that don't show up unless you're looking for them.

How broken links hurt your SEO

1. Wasted link equity — Every internal link passes SEO authority ("link juice") from one page to another. When a link points to a 404 page, that authority is wasted. It's like having a pipe that leaks before the water reaches where it's needed.
2. Crawl budget waste — Google allocates a limited number of pages it will crawl on your site per visit. Every broken link it encounters is a wasted crawl. For large stores with thousands of products, this means important new products might not get indexed as quickly.
3. Weakened site structure — Internal links help Google understand the relationship between your pages and which pages are most important. Broken links create gaps in this understanding.
4. Negative user signals — When users hit 404 pages, they bounce. High bounce rates and short sessions signal to Google that your site isn't providing a good experience, which can affect rankings indirectly.

Where broken links come from

In eCommerce stores, broken links are almost always unintentional. The most common causes:

• Deleted or sold-out products — You remove a product but don't update the collection pages, blog posts, or navigation menus that linked to it. This is by far the most common source.
• URL changes without redirects — Renaming a product, changing slugs, or restructuring collections creates new URLs. Without 301 redirects from the old URLs, every existing link to the old URL becomes broken.
• Typos in manual links — Blog posts, email campaigns, and custom page content often contain manually typed URLs that have subtle typos.
• Theme or platform updates — Changing themes or updating your eCommerce platform can alter URL structures, breaking links that worked before the update.
• External links that rot — Links to other websites (supplier pages, reference articles, partner sites) break when those sites change or go offline.

Finding broken links at scale

You won't find broken links by browsing your own store — they hide in old collection pages, blog posts, and footer links that you rarely visit. You need a crawler that checks every link on every page.

RankCart's audit crawls your entire store and flags every broken internal and external link, showing you exactly which page contains the broken link and where it was supposed to go. This makes fixing them straightforward — you can see the source page, the broken URL, and decide whether to update the link, set up a redirect, or remove it.

Fixing broken links: the priority order

1. High-traffic pages first — A broken link on your homepage or top-selling collection page affects more users and more SEO authority than one buried in an old blog post. Fix these immediately.
2. Set up 301 redirects for deleted products — When you remove a product, redirect its URL to the most relevant alternative (a similar product or the parent collection). This preserves any SEO authority the old URL had.
3. Update internal navigation — Check your header, footer, and sidebar menus for links to pages that no longer exist.
4. Fix or remove external links — If an external link is broken, either update it to the correct URL, link to an alternative source, or remove the link entirely.
5. Prevent future breaks — Set up a process: whenever you delete a product, check what linked to it and set up redirects. Weekly automated audits catch anything you miss.
