Generally you have two types of links on your site so if any one of them is broken it can harm the usability of your site:
Broken links cause when the owner has no control over these links. It can harm your site SEO because SEO considers the usability of your website and it takes into account such problems which occur when search engine spider causes or comes with a lot of dead ends. Firstly it indicates that your site is not properly working or properly managed by the owner. It abruptly results with the suspension of the movement of search spider, and if search spider comes with a lot of stop sign or 404 error pages it definitely diminishes the value of your site in the eyes of search engine. Such 404 error page also irritates the general user or any website user as it takes a lot of time and effort of the user to get understanding about your site. It creates more problems when the user left the site after the wastage of little time and effort. So the broken links only results in the loss of website user and the credibility of your site. It would definitely be annoying that you search a link and it answers your question that the data you are trying to find does not exist here.

If you own a large website like an e-commerce or a site with a large number of products then a few broken links cannot destroy the worth and usability of your site but if you own a small website with managing limited products then a few such links can badly harm and damage your site SEO. You must remove the outdated links from your site so Google considered that you are very much concerned with the relevancy of your content.
