Benefits of Using HTTPS
Google ranks HTTPS sites more favorably. Converting your site to HTTPS will improve your Search Engine Optimisation (SEO).
Your site visitors’ information is encrypted, and therefore more secure.
Many users are more comfortable making purchases and sharing their personal information online when visiting secured sites.
Google Chrome will soon begin displaying warnings anytime that a user visits a site that is not using HTTPS. Therefore if your site is not secured, your site visitors will get a warning message anytime they access your site.
