The SSL certificate of UCC relates to security and information security. The certificate confirms the authenticity of the site. In electronic form, the SSL UCC certificate looks like a label that is readable by a search engine or browser when accessing a domain name. The absence of an electronic tag initiates a refusal to download and read the content.
When accessing a domain name, browsers request a certificate of authenticity. This is done by all search engines, except for highly specialized search precisely for illegal information. If the certificate is not confirmed, the page does not load. In some browsers, the user may continue to load the page with an unconfirmed certificate. In most browsers, the user is deprived of this opportunity. No certificate - no download and no participation in the search.
Sites that do not have a certificate are removed from search engines, which negates all the work on the site, keywords, content and uniqueness. Promotion of a site that does not have a certificate of authenticity is impossible in principle.
Quite often, hosting services issue SSL certificates to several entry-level domains automatically. The cost of certificates is included in the price of placement. Hosters have every reason to issue a certificate to their customers:
A hoster acquires multi-domain SSL and assigns rights to its clients. To a large extent, the hoster is responsible for its customers. This is the reason for strict restrictions and rules on the placement of content.
Attention! Certificates must be annually updated and renewed. In the electronic label is embedded date of issue and expiration date. If SSL is not extended, the user is notified that the resource is not secure. Search engines can exclude a resource from search. Recovery is usually accompanied by problems with the uniqueness of the site materials in the search engine accounting system.
Many large and small companies and even private individuals professionally engaged in Internet technologies, prefer to keep their sites on their own servers. In this case, the certificate of authenticity must be purchased independently.
You can buy a certificate for one domain, but this is not very convenient, since any large site contains subdomains for search engine optimization. For example, the domain my_site.ua may contain the subdomains forum.my_ site.ua, shop.my_ site.ua and so on. Each of these resources requires a separate authentication. Buying a multi-domain ssl certificate is easier than confirming each subdomain separately. Not necessarily your sites should be linked by subdomains. If you have several different sites with different names and even in different domain zones, you can still use a multi-domain SSL certificate.
