HTTP is an application protocol used to transfer data on the Internet. It is based on "client-server" technology, which means that the initiator of data transfer is always the client, while the server only receives and processes the request, sending back the results.
The HTTP protocol transmits hypertext without any encryption, while HTTPS is a more secure technology with SSL encryption.
HyperText Transfer Protocol Secure guarantees the site a higher level of privacy and security of personal data, as all transmitted data are encrypted by SSL-certificate. That is, even if the data stream is intercepted, attackers will not be able to parse anything without a key - only the sending client and the receiving server have a key.
Switching to HTTPS provides other benefits besides security:
The only significant disadvantage of HTTPS is the need to buy an SSL certificate. How much it costs depends on the brand of the issuing company. On average, you will have to spend between $10 and $1,000 per year on an SSL certificate.
The algorithm will vary depending on the starting conditions. What kind of hosting you have, who the provider is, what the terms of cooperation are, etc. Here's what you need to do in the preparation phase before switching to HTTPS:
Then you need to buy an SSL-certificate, choosing the best option for you out of 5 types. They are:
It is clear that the more complex the certificate, the more time it will take to issue it, and the higher the cost. But as a result, the organization will get serious competitive advantages in terms of security and promotion over those companies that use the simplest and most affordable SSL certificates. In any case, the choice is yours.
Everything is simple here - in the hosting control panel, visit the "SSL certificates" section and click on "Add Certificate". Select "Existing" and fill in the appropriate fields in the tab that opens. Here you need to specify:
You will receive a part of this data after the certificate is issued and activated in the corresponding email, which is sent to the specified contact email address. Be careful, because the CSR-request and private key are generated right during the purchase and are not sent to the email - they must be saved on your computer before closing the tab.
After connecting the certificate, you must verify that everything is installed correctly. To do this, go to the site first via HTTP and then via HTTPS. If the site is accessible in both cases, everything works as it should.
In the final stage, it’s IMPERATIVE to notify the search engines about the transition - without this you may lose your position in the search engine results, and your traffic will decrease. In other words, you must visit the Yandex.Webmaster and Google Search Console panels, adding a link to your resource with the updated security protocol to their databases. You will be asked to confirm ownership of the site - this is done in a couple of minutes.

You should also specify the address of the main mirror of your site by making appropriate changes to the robots.txt file. This can be done by any webmaster.
And the final touch - update your Sitemap in Search Console. You can do this in the webmaster panel through the "sitemap files" subsection. That's the end of our material.
