Imagine you’re a librarian, and someone comes in with a request for a book that doesn’t exist. You’d have to tell them you can’t find it, right? That’s essentially what a 4xx client error is. It’s a message from your website’s server to a user’s browser, letting them know that the page they’re looking for can’t be found. While these errors are a normal part of the web, a large number of them can be a sign of a problem that could be hurting your SEO.
Think of 4xx errors as broken links. If a user or a search engine crawler follows a link to a page that doesn’t exist, they’re going to hit a dead end. This can be a frustrating experience for users, and it can prevent search engines from properly crawling and indexing your site. For a broader look at how search engines interact with your site, see our guide on crawling and indexing.
The SEO Impact of Broken Links
4xx errors can have a number of negative consequences for your SEO:
- Wasted Crawl Budget: Every time a search engine crawler hits a 404 error, it’s a wasted request. This can prevent the crawler from finding and indexing your important pages.
- Loss of Link Equity: If you have backlinks pointing to pages that no longer exist, you’re losing out on the SEO value of those links.
- Poor User Experience: A website with a lot of broken links is a frustrating experience for users. This can lead to a high bounce rate and a negative perception of your brand.
