SSL Certificate Providers

Most blogs, information, review type sites you can get away with free SSLs.
If you're taking payments then processors will demand a secure SSL with financial compliance.

World Pay as an example; All merchants who receive credit or debit card payments must meet Payment Card Industry Data Security Standards (PCI-DSS) to protect cardholder information.

That may very well be the case for some payment processors.
Stripe though, for example, actually recommends let's encrypt in their security protocol.
https://stripe.com/docs/security

I'm not sure if you're allowed to store payment data with such an SSL cert though.

Some hosts give you a special SSL deal for a year or two, can't remember the names (you can google).
 
Free is the Let's Encrypt. Let's Encrypt will be renewed automatically after 90 days. It has automated tool for the installation. Let's Encrypt has been approved by the most of the platform. It is most trusted SSL certificate.
 
Let's Encrypt.
Nowadays, cPanel issues free ssl for newly added domains. But some greedy
hosts like namecheap makes it difficult to activate it, doesn't allow to run scripts
for free ssl installation.

So, I used sslforfree.com which generates ssl from Let's Encrypt.

Domain validation ssl are all same whether you get free or paid.
 
Let's encrypt works very well, just make sure to set up a crone job to automatically renew it as it expires every 90 days. It's free, it's trusted, and worth the extra few minutes of your time to set up the auto-renew.
 
If you are looking to implement SSL certificate on your website without spending $ then you can get a free SSL certificate from a service called Lets Encrypt. This certificate will give you all the benefits of SSL without spending any $. If i say in-depth about Lets Encrypt than it is a collaborative project with Linux foundation and new certificate authority sponsored by Mozilla, Akamai, Siteground etc.. which offer SSL certificate in free.
