You can check the status code your site generates using the Google Search Console.

As shown in the figure, error pages should not appear in search results, as this is very bad for usability. If the webmaster/developer applies a 404 status code, the page will never enter Google's index. However, he may not notice and provide a 200 status code, causing Google to think that it should index this page (ultimately reducing the chances of the website ranking in the search engine).

Security
When you enter a URL in the search bar, your browser asks for the IP address of the site, for example 123.456.7.89, this number is the actual address where the website is online. The browser connects to this number, hoping that this is the right site, all in plain sight, there is no encryption to see, so everyone can intercept this traffic. Therefore, when you want to log in to a site that connects via HTTP, the data you enter (username and password) will be sent in plain text, which is really bad, think about what would happen if you connected to your bank in this way.

HTTPS protects this process, it encrypts the link between the browser and the website, thus ensuring that no one can intercept the data sent between the two. Every site that wants to protect itself needs a so-called SSL certificate. The browser checks the website's certificate and verifies its legitimacy with the company that issued it. By using HTTPS, websites not only protect your login process and personal data, but also what you do on the website and the websites you visit.
