Before moving on to how to convert into HTTPS from HTTP let's just get to know the reason or need behind. Google has been pushing hard for HTTPS everywhere so that web becomes a safer place to surf. Security is the number one reason why it's being pushed so hard by Google. But there are other reasons or advantages as well.
HTTP/2 is being rolled out by content delivery networks and web hosting providers. To take advantage of HTTP/2 performance benefits you have to be running over HTTPS because of browser support.
2. SEO and Rankings
HTTPS can help you improve your SEO rankings.
3. More Secure
The most important reason like we mentioned before of converting HTTP into HTTPS is security. If you aren't running over an HTTPS connection your username and password are sent in clear text over the internet.
4. Builds Trust and Credibility
It helps you build your trust and credibility with your visitors. All the website visitors today are concerned about their data being intercepted or being misused online. By adding SSL (secure socket layer) you instantly build trust and credibility among your visitors. It is important for the visitors to know that your website is safe and that their information is protected.
Follow this guide below to convert HTTP to HTTPS for your website.
1. The first and foremost thing is that you'll need SSL Certificate. These are small data files which binds a key to a specific organization's details. When it is installed it activates the HTTPS protocol which allows a secure connection between a web browser and a server.
2. Depending on what software you're running the steps to install SSL Certificate can vary. Once you have installed your certificate you will want to check to see if there are any issues with it. The following tools can be very helpful.
3. Using relative URLs is always the best practice but there will always be times when someone has hard coded a URL and so you will want to do a full sweep on your site and database during an HTTP to HTTPS migration.
4. Adding 301 redirects to new HTTPS URLs is probably one of the most important steps in converting HTTP to HTTPS. 301 redirects are a permanent redirect which passes between 90-99% of ranking power to the redirected page. If you don't implement 301 redirects you could seriously hurt your SEO rankings and your site could completely drop out of SERPs overnight.
