SSL certificate UCC refers to the protection and information security. The certificate confirms the authenticity of a website. In electronic form, the UCC SSL certificate looks like a label that is read by a search engine or browser when accessing the domain name. The absence of an electronic tag initiates a refusal to download and read the content.
When a domain name is accessed, browsers request a certificate of authenticity. All search engines do this, except for those highly specialized for searching specifically for illegal information. If the certificate is not validated, the page does not load. In some browsers, the user can continue loading the page with an unconfirmed certificate. In most browsers the user is deprived of this possibility. No certificate - no loading and no participation in search.
Sites without a certificate are removed from search engines, which negates all 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 hosts issue SSL certificates for several entry-level domains automatically. The cost of certificates is included in the price of hosting. Hosters have every reason to issue a certificate to their customers:
The hoster purchases multi-domain SSLs and assigns the rights to its customers. To a large extent, the hoster is responsible for its customers. This is the reason for the strict restrictions and rules on content hosting.
Attention! Certificates must be annually renewed and extended. The electronic tag has the issue date and expiration date sewn into it. If SSL is not renewed, the user is notified that the resource is not safe. Search engines may exclude the resource from searches. Restoration is usually accompanied by problems with the uniqueness of the site materials in the accounting system of search engines.
Many large and small companies and even 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 it is not too convenient, because any large site contains subdomains for search engine optimization purposes. For example, the domain my_site.ua may contain subdomains forum.my_site.ua , store.my_site.ua and so on. Each of these resources requires a separate confirmation of authenticity. Buy a multi-domain ssl-certificate is easier than confirming each subdomain separately. Your sites don't necessarily have to be linked 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.
