First of all, this means that all blogs get a free SSL certificate at blogspot, whether it's something you want or not. Previously, the webmaster was the one who decided whether the HTTPS was suitable for your site. Today it has become mandatory, which means that you have to be prepared for the benefits and possible consequences.
Those who log in to their Blogger account will see the message and can interpret the ramifications of what it really means. It should be noted that this is only for domains on Blogger.com that are free and that the custom will continue to function as they have done in the past. This means that no support is provided by free SSL HTTPS to custom domains.
While this will of course cause some concern for webmasters, because Blogger.com has some limitations that are common knowledge, the truth is that this particular change can lead to a better, more secure experience for people who visit the sites and Positive influence on search engine optimization (SEO).
What is HTTPS?
The use of Hyper Text Transfer Protocol Secure (HTTPS) is in fact a secure version of HTTP. This means that the data transferred between the user and the server is now encrypted and protected against access or hacking of unwanted third parties.
HTTPS as a ranking signal
Perhaps the most striking impact is the influence of the SEO on your site. In particular, Google places more importance on HTTPS compared to HTTP sites, but thanks to the extra security, the secure connection actually has a positive effect. Better security means higher ratings for your blog.
In addition, your blog may run a bit better with a secure connection compared to your competition, some of which might not have such a connection.
Since all your traffic is now automatically redirected, there will be no negative effect in terms of loss or reduction of your SEO. In fact, this is actually a good move for blogspot.com and it is certainly a valuable addition to all their blogs because the support provides solid benefits for any blogger using their domain.
