How much link equity does a 301 redirect pass?

Google has stated that 301 redirects pass the same amount of PageRank as a direct link — essentially 100%. Previous beliefs that redirects lose 15–20% link equity were based on older algorithm behaviour and Google has since clarified this. A well-implemented 301 redirect preserves link equity effectively.

Should I fix all 404 errors on my site?

Not all 404s need fixing. A 404 for a URL that has never existed, has no inbound links, and has never been in Google's index is harmless. Focus on: 404 URLs with external backlinks (lost link equity), 404 URLs that GSC has indexed or is attempting to crawl, and 404 URLs that internal pages link to (broken internal links).

What is a soft 404 and why is it a problem?

A soft 404 is a page that returns a 200 OK status code (meaning 'page found') but actually shows a 'page not found' or empty content message. Google detects soft 404s and treats them as low-quality pages — they can be indexed but won't rank, and they waste crawl budget. The correct response for a missing page is a true 404 status code or a 301 redirect.

How long should I keep 301 redirects in place?

Permanently, or for at least 1–2 years from the redirect date. Google recommends keeping redirects in place long enough for all crawlers and users to update. Removing redirects too early can bring back 404 errors and lose the link equity that has been consolidating. For high-traffic pages, consider keeping redirects indefinitely.

Do 404 errors on my site affect rankings of other pages?

Indirectly — yes. A site with hundreds of 404 errors has a crawl budget problem: Google wastes time on dead URLs instead of crawling your good content. This can slow down indexing of new pages and reduce the crawl frequency of existing pages. Large numbers of 404s (1,000+) can have a measurable crawl budget impact, especially on smaller sites.

404 Errors & Redirects — How Broken Pages Leak SEO Value

Every 404 error on your site is a dead end for both users and Google's crawlers. Every unnecessary redirect is a speed bump that loses a fraction of your link equity. Managed correctly, redirects preserve ranking signals during site changes. Managed incorrectly, they can undo years of SEO work.

Direct Answer

A 404 error means a page has disappeared and any backlinks pointing to it are wasting their authority — on site migrations, we insist on a complete redirect map before launch because missing redirects can eliminate years of accumulated link equity overnight.

Broken links and missing redirects are a silent SEO drain we fix in every audit. For site migrations, we insist on a complete redirect mapping before anything goes live — every old URL must route to its equivalent new page, or years of link equity can vanish overnight.

What Are 404 Errors and Redirects?

A 404 error (Not Found) means a URL was requested but no page exists at that address. For SEO, 404s are problems when: other websites link to that URL (lost link equity), Google has the URL indexed (wasted crawl budget and poor user experience), or internal links on your site point to it (broken user journeys). A redirect is a server instruction that tells browsers and crawlers that a URL has moved. A 301 redirect is permanent — it passes approximately 99% of link equity to the destination URL and tells Google to update its index. A 302 redirect is temporary — it passes less link equity and tells Google to keep the original URL in its index. Most SEO redirects should be 301s. Temporary redirects should only be used for truly temporary situations.

Why 404s and Redirects Matter for SEO

External links pointing to 404 pages lose all their link equity — that authority simply disappears
Google wastes crawl budget on 404 URLs it has indexed — reducing the time available to crawl your good pages
Redirect chains (A → B → C) lose equity at each hop and add unnecessary latency
302 redirects used where 301 is correct can prevent Google from consolidating link equity to the destination URL
Site migrations without proper redirect mapping are the most common cause of sudden, severe ranking drops

How We Audit and Fix 404s and Redirects

Crawl for all 404 errors and redirect chains

We crawl your site and identify: all URLs returning 404 (internal and external), all redirect chains longer than one hop, and all 302 redirects that should be 301s. We also pull the 404 report from GSC for URLs Google has attempted to crawl.

Prioritise by inbound link equity

Not all 404s are equal. We prioritise fixing 404 URLs that have external backlinks — those are losing link equity. 404 URLs with no inbound links and no GSC crawl data are lower priority.

Map 301 redirects from old URLs to most relevant new URLs

Every 404 with inbound links gets a 301 redirect to the most topically relevant live page. If a deleted product page is no longer available, redirect to the category page — not the homepage.

Monitor GSC Coverage for new 404s

After fixing, we monitor GSC Coverage and set up alerts for new 404 errors introduced by future content changes. Ongoing monitoring prevents 404 accumulation.

Redirect Mistakes That Lose Link Equity

Using 302 redirects instead of 301 for permanent moves

A 302 tells Google the move is temporary and to keep the original URL indexed. If you're permanently redirecting a page, use 301. This is often misconfigured in CMS settings or htaccess files.

Redirect chains: Page A → Page B → Page C

Each redirect hop dilutes link equity slightly and adds latency. Compress all chains to direct A → C redirects. Audit redirect chains monthly for active sites.

Site migration without redirect mapping

Redesigning a site and not redirecting old URLs is the most common cause of catastrophic ranking drops. Every old URL that had inbound links or Google traffic must have a 301 redirect to its replacement.

Redirecting all 404s to the homepage

Soft 404s — pages that redirect to the homepage with a 200 status — are a Google guidelines violation. Google treats them as 404s anyway and may penalise the site for manipulation. Redirect to the most relevant available page, not always the homepage.
