With internet security becoming a major cause of concern, more and more websites (especially transactional and membership based ones) are opting for SSL certificates that increase visitor security by encrypting the data transmitted between the client (visitor’s browser) and the server (which hosts the website).
Apart from making websites secure for visitors, these SSL certificates also increase a website’s credibility and also its search engine ranking, as browsers these days (especially Google’s Chrome which is the most popular browser at the moment) recommend only websites which contain SSL certificates as ‘secure ones’.
Studies indicate even a blog can benefit from an SSL certificate as it’s known to boost search engine ranking.

How the Different Types of SSL Certificates help in protecting website.
There are a range of SSL certificates that would help to secure the business websites and its customer information, however all the SSL certificates work on the same principle with just a few differences with serve specific set of demands with unique traits to serve the purpose.
#1. Single Domain
Single Domain SSL Certificates secure websites with a single domain and not with sub domains
it is good to protect – www.abc.com and it does not work to protect the information of its supporting subdomain – menu.abc.com
#2. Multi-Domain (SAN)
Multi-domain SSL certificates as the name says secures websites with multi domains and in common known as SAN (Subject Alternative Names). So one certificate to protect all the domains (100 to 200 domains) of the websites.
Wildcrad SSL Certificate works well to protect all the subdomains on a single host name
for instance a business website www.shopcart.com has the following subdomains
Wildcard SSL helps to protect www.shopcart.com and its subdomains mail.shopcart.com, login.shopcart.com, shop.shopcart.com and order.shopcart.com. Hence there is never a need of multiple number of certificates to protect each of the domain.
#5. Extended Validated Certificate
