Nothing drives people away from your website faster than a slew of broken links. Imagine clicking on a link and expecting to learn more about a topic or see a great video. Instead, you’re hit with the infamous 404 error — a virtual dead end that leaves you wondering what could have been.
Having a broken link once in a while probably won’t cause a big problem. But if visitors constantly run into errors on your site, they will stop coming back. Broken links make your site seem poorly maintained, both to users and web crawlers. Over time, your site ranks lower and lower in search engines, which means fewer people will find you through organic search.
