This shows that there is no URL in this server, and the user will leave your website. Broken URL affects your SEO, and this will ultimately affect your website speed.
Broken URL affects your SEO in three ways:
Broken URL negatively affects your SEO
Broken links turn users away.
Google frowns upon dead links.
Broken URL can be identified by:
When you search and find out that this page does not exist by seeing 404 errors
You may not know about the broken URL that your website has, or you had deleted your page, and Google has indexed your page before you delete this page. In this case, this page will exist/remain in the Google database, and when a user lands on this page, it shows a 404 error that shows that this page does not exist now.
Changing URL of the live page, i.e., if you write an article or do changes in topic or an article, it will change URL, so you have not deleted this page makes some changes or changes its name.

If you migrate your website or page means if you have a new website/page in place of the old one and if these broken links bring traffic, give this page or website 301 redirection command. If these pages do not bring any visits and serve a necessary purpose, then eliminate these broken links or pages.
In this redirect command, you give an old URL a new address. When Google/user goes to an old URL, the browser will show a new URL, and in this way, Google/user will land on a new page without knowing that it’s a new page.
When Google index this page that does not exist but has 301 redirections, then Google understands that this page has a new address now, and the old address has deleted, so in Google database new address will be indexed.

Move your website to a better server (Hosting) for website speed optimization.
Means, whether you’re hosting is good or bad, i.e., if you open your website in Pakistan, but its server is in the USA, then it will take time to load because of a long call that goes to the USA server and back again.
Besides this, you can have good hosting but not the good hosting package that when its limit expires, then your website speed gets down.
Shared hosting in which you share server space with other companies can affect your website speed due to many people who are using the same server. But the Shared hosting package has low fees to get your site online in a short time. So dedicate server, and the virtual private server are the best options for your website speed optimization.

AWS, Microsoft Azure, Google, or other public cloud providers are some options to rent a dedicated server.
A virtual private server is a much faster server like a dedicated server. Although you also share your server with other websites, you have your own part of the virtual server that protects your website from everyone else on your server without any cost, unlike a dedicated server.
