As a professional, I`m excited to explain what STS agreement is and how it`s relevant in today`s digital age.

STS agreement stands for « Secure Transport Security » agreement. It`s a protocol that ensures secure communication between websites and web browsers. This agreement was introduced by Google in 2018 as a means to enhance website security and protect users` personal information.

The STS agreement works by requiring websites to send a signal indicating that they support HTTPS (Hypertext Transfer Protocol Secure) connections. This signal is then saved by the user`s browser, which automatically redirects HTTP requests to HTTPS, ensuring a secure connection between the website and the user`s device.

In simpler terms, STS agreement is a security measure that forces websites to use HTTPS connections. HTTPS is a secure version of HTTP, which encrypts the data shared between the website and the user. This encryption ensures that any sensitive data, such as usernames, passwords, and credit card details, are protected against potential hackers and cybercriminals.

Google has made the STS agreement mandatory for websites that wish to use their search engine. In other words, websites that do not implement the STS agreement will receive a warning from Google that their site is not secure, potentially leading to a drop in traffic and a decrease in search engine rankings.

As an experienced copy editor, it`s essential to understand the relevance of STS agreement for SEO. In addition to the negatives mentioned above, websites that don`t implement the STS agreement may also face difficulties in generating backlinks. This could lead to a loss in domain authority and a decrease in online visibility.

Therefore, as an SEO-focused copy editor, it`s essential to make sure that all website content is optimized for HTTPS connections. This means checking that all internal and external links start with «  » instead of «  ».

In conclusion, the STS agreement is a critical security measure that all websites must implement to ensure their users` safety and maintain their search engine rankings. As a professional, it`s crucial to understand the relevance of STS agreements and optimize website content to ensure it complies with this security protocol.
