404 Not Found
Can you explain 404 Not Found like I'm new to SEO?
Absolutely. A 404 Not Found error is what a website shows when someone tries to visit a page that doesn't exist. It's like showing up at a storefront and finding the door locked with a "moved out" sign-no forwarding address, no explanation.From an SEO perspective, 404s aren't automatically bad-but they can cause issues if you're not managing them properly.
Here's what you need to know:
Google doesn't penalize you for having 404s, but if important pages that used to rank suddenly return a 404, you're going to lose any traffic and rankings tied to them.
If users keep hitting 404s from search results or internal links, it signals a poor user experience. That can impact bounce rates, crawl efficiency, and overall trust in your site.
It's a missed opportunity-if the page no longer exists but people are still trying to visit it (maybe they bookmarked it or another site linked to it), you're essentially wasting potential traffic.
That's why it's best practice to either:
Set up a 301 redirect to a relevant, active page, or
Create a custom 404 page that's helpful-maybe with a search bar, links to popular pages, or a call to action.
Think of a 404 as a dead end. You can't eliminate all of them, but you can make sure your users-and search engines-don't get stuck there.
