What is SSL?
In order to comprehend what SSL is, it is necessary to first understand what HTTPS is. HTTSP stands for Hyper Text Transfer Protocol Secure and is usually used on websites to safeguard e-commerce transactions. For instance, a user connects to online banking websites or e-commerce sites via HTTPs, these websites will inevitably encrypt the session with a digital Secure Socket Layers (SSL) Certificates.
SSL certificates are small data files that digitally bind a cryptographic key to the domain of a particular website. Once the SSL certificate is installed, a secure connection gets enabled between the web server and web browser. This connection helps in stopping any visitor who is prying on the connection.
Unfortunately, SSL certificates have been used only by a mere 10 per cent of websites.
What is the Impact of SSL on Search Engine Rankings?
Quite recently, Google made an announcement that having an SSL certificate will help site owners to significantly boost their SEO rankings. Adding a SSL 2048-bit key certificate on your site will fetch only a minor ranking boost. Google says that this will give websites only a small ranking benefit, which can be counted as a “very lightweight signal” as per the overall ranking algorithm. Google thinks it has an impact on “less than 1% of global queries” but further added that they may decide to strengthen the signal as they plan to encourage all website owners to switch from HTTP to HTTPS in order to keep all transactions safe and secure.
Google conducted few tests and the HTTPS signals showed ‘positive results’ in terms of relevancy and ranking in Google’s search results.
