What is a 404 error?
By Mark Boreland ·
In short
- A 404 error is the browser saying the page at this address does not exist.
- Shared files most often 404 because the file moved, was renamed, or the host expired the link.
- A broken link in a job application or a client email costs you at the worst moment.
A 404 is the status code a server returns when there is nothing at the address requested. The link looks fine, the visitor clicks, and they land on a dead page. For most browsing this is a minor annoyance. For a shared file it is expensive, because the people clicking your link are usually the people you most want to reach: a recruiter opening a portfolio, a client opening a proposal, a guest opening directions to a venue.
Most broken share links come from the file moving. You re-upload a portfolio to a new folder, the old URL stops resolving, and every place you pasted the previous link now 404s. This is exactly the failure NudgeHost is built to avoid. When you update a file the URL stays the same, so someone who wants to get your portfolio in front of a recruiter can swap in a new version without invalidating the link already on their CV. The only deliberate way a NudgeHost link stops working is if you set it to expire, which is a feature rather than an accident.
If you do need a link to stop resolving on a schedule, that is what how link expiry works is for, and a deleted file returns a clean message rather than a confusing dead end. Hosting is free to start, and our pricing covers the higher limits. The short version is that a 404 should be a choice you made, never a surprise your recipient finds.

Frequently asked questions
Why did my shared link suddenly 404?
Usually the file moved or was renamed on the host, so the old URL no longer points at anything. On NudgeHost, updating a file keeps the same URL to prevent this.
Does a 404 hurt my SEO?
A few are normal. Many broken links on a site you control waste crawl budget and frustrate visitors, so they are worth fixing.
What does a NudgeHost link show when a file is gone?
If you delete a file or it expires, the link shows a clear message explaining the file is no longer available, not a raw error page.
