Error 403 can occur when searching on Google with any Web browser such as Chrome, Internet Explorer or Firefox. The error indicates that the browser can't access the Web page for a variety of reasons.
When attempting to access a Web page that a user clicks on from the Google search results, the browser must complete a cycle of interaction with the file. The first step in the cycle is to obtain the Internet protocol address of the Web page. Next, the browser will attempt to connect to and send a message to the IP socket that is connected to that address. It then waits to receive a stream of data from the address, but if the file is unavailable or forbidden, the error 403 may be displayed.
Types of 403 Errors
There are actually 22 types of 403 errors ranging from 403.1 to 403.22. Each error represents different forbidden error code. For example, error 403.2 means that the browser is forbidden from reading the file, 403.8 means the site access is forbidden and 403.9 means there are too many users.
Fixing 403 Errors
The error may be received because the website is no longer available and no redirect URL is provided. If a particular Web page is missing, it must be uploaded into the correct directory and saved as the correct file name to prevent the error. If the Web page requires authorization, the user should revert to the homepage of the site and enter the necessary information to access the page.
