Why broken links and redirect chains hurt a redesign, and how to find them

A redesign can look like a success on launch day and still be quietly losing rankings, traffic, and enquiries for weeks. The cause is rarely the design itself. It is the links that broke when pages moved, and the redirect chains that grew as one redirect was layered on top of another. Neither problem announces itself. Visitors simply reach dead ends, search engines waste their attention on pages that no longer exist, and the business loses the value its old pages had earned.

Broken links and redirect chains are not cosmetic issues. They affect how search engines understand a site, how much of the site they explore, and whether visitors trust it enough to enquire. Finding them is straightforward, and fixing them is usually simple, once they are found. The work is worth doing before launch, and worth repeating after it.

How broken links and chains actually hurt

A broken link wastes the authority that the linking page had to pass on. When a link points to a page that returns an error, the value that link carried is lost, and the visitor who followed it reaches a dead end. A few broken links on a large site are normal and harmless. Dozens of them, especially on important pages, signal neglect to both visitors and search engines.

Redirect chains cause a slower, subtler form of damage. A chain occurs when one URL redirects to a second, which redirects to a third, and so on, before the visitor reaches the final page. Each step adds delay, and search engines may stop following the chain before they reach the destination. The destination page then receives less authority than a direct redirect would have passed, and the visitor waits longer for every page that sits behind a chain.

Where they come from in a redesign

Redesigns change URLs. Pages are renamed, merged, split, or removed, and the links that pointed to them are not always updated. Internal links in old blog posts, links in navigation menus, and links from other websites all continue to point at the old addresses. If a redirect map is incomplete, those links break. If redirects are added in stages, with each stage redirecting to the previous stage’s target, chains form.

Chains also form over time, as a site is redesigned more than once. A page that was redirected in the first redesign is redirected again in the second, and again in the third, until a single click passes through three or four addresses. Each redesign adds a layer, and nobody removes the earlier layers, because nobody owns the redirect map as a whole.

How to find them

Start with a crawl of the whole site, using a crawling tool that reports broken links, redirect chains, and the pages that link to them. A crawl will find the problems that manual checking misses, because it follows every link on every page, including the ones buried in old posts and footers. Run the crawl on the staging site before launch, and again on the live site afterwards, because the two are not always identical.

• Crawl the staging site before launch, and fix what the crawl finds.
• Crawl the live site within days of launch, and compare the results.
• Check search console reports for pages that return errors or that search engines cannot reach.
• Review analytics for pages with sudden drops in traffic, which can signal a broken destination.
• Test the most important landing pages by hand, following the links a visitor would follow.

How to fix them properly

Fix a broken internal link at its source, by pointing it at the correct live page, rather than by adding a redirect. Redirects are for links you cannot change, such as links from other websites, bookmarks, and search results. Internal links you control should point directly at their destination, with no redirect in between.

Fix a redirect chain by collapsing it. Every redirect in the chain should point directly at the final destination, in a single step. Remove the intermediate steps, and check that the final destination returns a successful response. A single, direct redirect passes more value, loads faster, and is easier to maintain than a chain that nobody remembers building.

For pages that no longer exist and have no equivalent, decide deliberately what should happen. A page with no replacement should return a helpful error page that explains the situation and offers a way forward, rather than redirecting to the home page, which confuses both visitors and search engines. A page with a clear successor should redirect to that successor, in one step.

How to stop them coming back

Make link checking part of the launch routine and part of regular maintenance. Crawl the site monthly, or after any significant change, and fix new problems promptly. Keep the redirect map in a single document, owned by one person, so that each redesign updates the map rather than adding a new layer on top of the old one.

The same discipline applies to the rest of the launch. The article on how to preserve enquiry forms and tracking when a redesign goes live sets out the inventory and testing approach that keeps forms and measurement working through a redesign, and link checking belongs alongside it in the same launch checklist.

Frequently asked questions

How many broken links are acceptable on a website

A small number on a large site is normal, and search engines expect it. The problem is scale and placement: dozens of broken links, or broken links on the most important pages, will cost rankings and enquiries. Aim for zero on key pages, and fix the rest as they are found.

Do redirect chains affect rankings directly

They reduce the value passed to the destination page, slow down loading, and can cause search engines to stop following the chain. The effect of a single short chain is small, but long chains and many chains together will hold a site back. Collapsing chains to single redirects is a reliable, low-risk improvement.

Should I redirect deleted pages to the home page

Usually not. A redirect to an unrelated page confuses visitors and is treated by search engines as a soft error. Redirect to the closest equivalent page, or return a helpful error page with links to relevant content. The right choice depends on whether a genuine successor exists.

How often should I audit links after a redesign

Crawl the site within days of launch, again after a month, and then monthly as part of routine maintenance. New broken links appear whenever content is edited, pages are removed, or external sites change, so a single audit is not enough. Regular checks keep small problems from accumulating.

Can broken links affect enquiries, not just rankings

Yes. A broken link on a service page, a pricing page, or a contact page can stop a visitor from reaching the information they need, or from completing an enquiry. The most costly broken links are the ones on the pages closest to conversion, which is why manual testing of key journeys matters as much as automated crawling.

A redesign should leave a site easier to navigate, not harder. Find the broken links, collapse the chains, and keep the map current, and the new site will keep the value the old site had earned.
