It is still possible to perform a Google search without using HTTPS, although it is not recommended due to security concerns.
HTTP (Hypertext Transfer Protocol) is a protocol used for transferring data over the internet, but it is not secure because the data transmitted between the user's computer and the server is not encrypted. This means that anyone can intercept and read the data being transmitted, including sensitive information like usernames and passwords.
HTTPS (Hypertext Transfer Protocol Secure) is a more secure version of HTTP that encrypts the data being transmitted between the user's computer and the server, making it much more difficult for anyone to intercept and read the data.
Google has been using HTTPS by default since 2014, and it is now the standard way to access Google search. However, if you manually type in "http://www.google.com" in your web browser's address bar, it will still take you to the non-HTTPS version of Google search. In this case, the data you transmit to Google may be intercepted and read by third parties, so it is strongly recommended to always use the HTTPS version of Google search by typing in "https://www.google.com" instead.
Additionally, some older devices or browsers may not support HTTPS, so in those cases, users may still be able to access Google search without HTTPS. However, it is important to note that using HTTP instead of HTTPS leaves your connection and data vulnerable to interception and manipulation by attackers. Therefore, it is highly recommended to ensure that you always use HTTPS when accessing Google or any other websites to protect your privacy and data security.
To clarify my previous statement, starting from June 2020, Google Chrome, the most widely used web browser, started defaulting to using HTTPS for all searches and does not allow users to access the non-HTTPS version of Google search. This means that regardless of whether you manually type "http://" or "https://" before the Google URL, it will automatically redirect to the HTTPS version. Other web browsers may also have similar default settings in place.
