How to Fix: 301 for permanent redirects

301 for permanent redirects is an important SEO check in the Technical Foundation category. This is a high-priority SEO issue that should be addressed soon. It has a significant impact on your SEO performance.

What this check is really asking

This check verifies that when a page moves permanently, you send a 301 redirect — not a 302, not a soft 404, not nothing. The status code is not a technicality. It is the instruction that tells Google “this address has permanently become that one; move everything you knew about the old URL to the new one.” A 301 passes the ranking equity across. The wrong code, or no redirect at all, throws that equity away.

When this check fails, you typically have permanently moved content served by temporary 302 redirects, or old URLs returning 404s with no redirect at all — years of accumulated authority quietly leaking out of the site.

Why the status code decides who keeps the rankings

• A 301 transfers the old page’s ranking signals to the new URL; a 302 tells Google to keep the old one, so the new page starts from nothing
• Inbound links keep working. Every external link to the old URL still lands the visitor and still passes value
• You avoid 404s that frustrate users and waste crawl budget on dead ends
• Search results stay clean — Google consolidates on the new URL instead of indexing a broken one

I watched an entire platform die and take its URLs with it

Let me date myself. I spent years building in Flash and ActionScript — whole sites, games, interactive shows, all of it living inside .swf files at their own URLs. Then Flash died. Not gradually from my point of view: browsers dropped it, and overnight every one of those addresses pointed at something that no longer ran. Every link anyone had ever shared, every bookmark, every search result — all of it landing on a dead end. That is when the lesson went in permanently: the content can change, the technology can die, but the address is a promise you made to everyone who ever linked to you.

A 301 redirect is how you keep that promise. It is the closest thing the web has to a change-of-address forwarding card: the thing at the old location is gone, but anyone who shows up is walked to where it lives now. When I moved that old Flash content to real HTML, the redirects were not an afterthought — they were the whole point, because without them every link the work had ever earned would have died with the plugin. Treat your redirects that seriously and you never hand your accumulated authority to a 404.

How to Fix This in WordPress

Difficulty Level: EASY – This fix is straightforward and can typically be completed by anyone with basic WordPress knowledge.

Estimated Time: 20 min

Step 1: Find the URLs that need redirecting

Pull the list of changed, deleted, or moved URLs. Google Search Console’s Pages report and a crawl will surface 404s and any existing 302s that should be 301s. Map each old URL to the single most relevant new destination — not just the homepage, which is a wasted redirect.

Step 2: Create the 301s

The easy route is a plugin — Redirection (free and excellent) or the redirect manager built into Yoast SEO Premium and Rank Math — where you enter the old path, the new URL, and confirm the type is 301. For server-level control you can add rules to .htaccess (Apache) or the Nginx config, which is marginally faster but easier to get wrong. For most WordPress sites, the plugin is the right call.

Step 3: Fix existing temporary redirects

Hunt down any 302 redirects that are covering permanent moves and change them to 301. This is the step people skip — a 302 “works” for the visitor, so nobody notices it is quietly refusing to pass ranking equity for months.

Step 4: Verify the fix

1. Test each redirect and confirm it returns a 301 status (browser dev tools Network tab, or a redirect checker) — not a 302 and not a chain
2. Confirm each old URL lands on the correct, relevant new page
3. Clear your WordPress cache if you’re using a caching plugin
4. Re-run the SEO Roadmap audit, then watch the old URLs drop out of Google Search Console over the following weeks

The redirect mistakes that quietly cost you

• Redirect chains. A → B → C bleeds equity and slows the page; always point the old URL straight at the final destination
• Redirecting everything to the homepage. Google reads a mass redirect to the root as a soft 404 and passes little value — map to the relevant page
• Using 302 for a permanent move — the single most common and most expensive redirect error
• Forgetting redirects during a site migration, which is where whole rankings evaporate in a week
