We changed the URL structure on the site recently. We said we redirected the old URLs, but someone must have forgotten. When we opened Search Console, guess what we saw: nearly 400 404 errors. It shows pages as completely deleted.

I know this will hurt SEO, but what do I do? Checking and fixing every broken page one by one will take hours. I haven't checked if these errors are in the sitemap yet.

Does Google perceive these 404s as permanent damage to the site? Or will it pass if I fix them? We saw a drop in traffic is it because of these 404s?

404 errors don't automatically lower the site's SEO value. However, if these pages had high-quality backlinks, that link juice is lost without redirection. In this case, a traffic drop is natural.

First thing to do: Export all 404 error URLs from Search Console. Identify the old addresses of these URLs. If these pages have a new URL, add a 301 redirect. If the page is completely deleted, redirect to a similar other page.

From now on, check the Fetch as Google pages. Is the redirect working? Is the target page correct? Then mark these URLs under the 'Coverage Error' category in Search Console, and Google will re-check them.

the traffic drop is definitely due to 404s meaning old backlinks are lost. we had this happen at the start we redirected all the 404s and traffic came back afteer 3 weeks.

404 Error Solution Steps: 1. Download error report in Search Console 2. Identify old address for each URL 3. Add 301 redirect (old → new) 4. Remove deleted pages from Sitemap 5. Submit 'Request Review' 6. Monitor for 2-3 weeks, it should fix itself

404 errors aren't considered harmful for SEO; however, they cause loss of backlink value. If no backlinks are coming from 404 pages, the traffic drop might be due to other reasons. Check the 'Search Analytics' tab to see which queries dropped.

Quick fix: Export 404 error pages from Search Console and add 301 redirects one by one. If there are too many and you're using an automated tool (like htaccess) do it in bulk. Then edit the sitemap so only existing URLs remain.

I went through the same thing.

The answer above hits the nail on the head. Don't hesitate to ask; those who don't ask always pay more.

Correct me if I'm wrong.

How did you solve this? Most time waste accumulates in tasks waiting for approval.

That's all, sorry if I went on too long.

There's a common mistake people make when doing this. Everyone rushing into 404 errors increased gets stuck at the same point.

Good luck with that.

Let me share my experience. Mistakes made on the 404 errors increased side are usually reversible but expensive.

Good luck with that.

The discussion got scattered, let me summarize. A competitor's ranking might come from years of accumulation, not just their content.

There's a common mistake people make when doing this. Speed is a threshold issue; if you're already fast, making it faster changes nothing.

The harder it is to reverse a decision, the slower you should make it. I'm also curious if anyone does it differently.

Let me summarize the topic, since several different answers were given. Any comment made without a control group is just a guess.

People defend habits, not processes. Resistance comes from there.

This is exactly what we experienced. A page that answers one question works better than one touching on five topics.

Good luck with that.

I think differently. Solutions that work at a small scale collapse when you grow; I learned this late.

When we decide without measuring, we always end up in the same place. Correct me if I'm wrong.
