A 404 error simply means the page someone requested no longer exists at that web address. Think of it like arriving at a business address and finding the building gone. The address still works, but there is nothing there. They happen when pages are deleted, URLs change during a redesign, internal links point to outdated pages, or external sites link to old content. The important thing to understand is that not every 404 is a problem. Context decides whether action is needed.
Do 404s Actually Hurt Rankings?
The impact of 404 errors is often overstated. Google expects websites to have some 404 pages, and a handful will not harm your rankings. Problems arise when 404s involve important service pages, pages with valuable backlinks, internal navigation links, or large portions of a site after a migration. We do not panic over a few 404s. We pay attention when they signal broader maintenance issues. A 404 is not a penalty. Its consequences only affect SEO when it is left unmanaged.
When to Leave a 404 Alone and When to Fix It
A 404 is generally fine when the page was intentionally removed, there is no suitable replacement, it gets little or no traffic, and nothing important links to it. A redirect is usually the right move when the content moved elsewhere, the old page had authority, users still try to reach it, or internal links point toward it. Lead with user experience, and the SEO benefit tends to follow.
404 vs Soft 404
A true 404 returns an actual HTTP 404 status code, telling search engines the page no longer exists. A soft 404 is different and trickier: the page appears broken or empty, but the server returns a 200 “OK” status instead of a 404. That confuses search engines because the page technically exists while providing no value, which wastes crawl resources and complicates indexation. We find soft 404s surprisingly often on poorly configured WordPress sites, which is one reason they are easy to miss.
How to Find 404s on Your Site
No single source gives the full picture, so we combine several. Google Search Console surfaces indexed pages returning errors and coverage issues. Screaming Frog detects broken internal links and crawl problems sitewide. Google Analytics shows traffic still reaching missing pages. Backlink tools reveal valuable external links pointing at 404s, which are the ones most worth recovering.
The Right Way to Handle a Deleted Page
| Situation | Best action |
|---|---|
| A relevant replacement exists, page has authority or traffic | 301 redirect to the replacement |
| Content is intentionally and permanently removed, no alternative | 410 status code |
| Page is obsolete, no links point to it, rarely accessed | Leave it as a 404 |
The one approach to avoid is redirecting everything to the homepage. It rarely helps users or search engines, and it strips away the topical relevance a proper redirect would preserve.
Where 404s Do the Most Damage
The most common and costly 404 mistake we see on business sites is redesigning a website without a redirect map. Old service pages disappear, backlinks lose value, traffic declines, and rankings slip. A close second is internal links pointing to outdated URLs for months or years without being corrected. Internal links that hit a 404 create dead ends that interrupt crawler pathways and waste crawl resources, and pages with backlinks that return 404s can lose valuable authority signals. For smaller sites the crawl impact is minor; for larger ones it compounds. Almost all of this is preventable with planning, which is exactly what we check in a technical SEO audit, and it ties directly back to clean site architecture.
Frequently Asked Questions
Do 404 errors hurt SEO?
A few 404s are normal and will not harm rankings; Google expects them. They become a problem when they hit important pages, pages with backlinks, or large parts of a site after a migration. The issue is unmanaged 404s, not their mere existence.
What is a soft 404?
A soft 404 is a page that looks broken or empty but returns a 200 “OK” status instead of a real 404. It confuses search engines because the page technically exists while offering no value, wasting crawl resources. Configuring the server to return a true 404 or fixing the page resolves it.
Should I redirect a deleted page?
Redirect it with a 301 if a relevant replacement exists or the page had authority or traffic. Use a 410 if the content is permanently gone with no alternative, and leave a true 404 for obsolete pages nothing links to. Avoid redirecting everything to the homepage.
