The simple answer is YES!
It is definitely a good idea for all businesses, big and small, to secure their websites with HTTPS.
So, what is a secure website and what is HTTPS?
It essentially means that the website utilises SSL (Secure Socket Layer), a standard security technology that establishes an encrypted connection between a web server and a browser, with the URL being prefixed with "HTTPS" rather than the standard and unsecure "HTTP" (with that extra "S" standing for "Secure").
A non-secure website has a URL that begins with “http” in the address bar, whereas a secure website begins with “https” — with the “s” standing for “secure”.
Reasons why your website should be secure:
Google recommends and customers expect it
Google now officially recommends securing websites with HTTPS, which means that not only will this be important for organisations that want their websites to perform well in search, but more and more visitors will come to expect it.
Having https improves your search engine rankings
In August 2014, Google announced that HTTPS is a ranking factor in their search algorithm. Research suggests it’s now an even stronger ranking factor. Just do any type of a Google search, and you will notice that nearly all the page 1 results begin with an HTTPS URL. Google has also indicated that a HTTPS site can serve as a tie-breaker between two sites offering similar information.
Browsers now shame unsecure websites
You may have noticed that most common desktop browsers such Internet Explorer, Chrome, FireFox, and even mobile browsers, such as Chrome on Android, and Safari on iOS prominently show lock icons to indicate when a site is secure via HTTPS. Chrome goes a step further by labeling standard HTTP sites as "unsecure".
Protecting your users, and your business
Finally, if Google's preference for secure websites isn't enough, consider your users and customers. If your site is not secured with HTTPS it essentially means that ALL data submitted through your website could be intercepted by someone who is not supposed to have it - this includes contact forms, logins, chat logs, and browsing patterns. Do you really want to expose your users, and your business, to that kind of risk?
What to do to make it HHTPs
You will need to purchase an SSL (Secure Socket Layer) certificate and have it installed, best to ask your website developer to do this for you.
