It's worth it, browsers mark sites that do not use https as insecure, so this may reduce the conversion, but you can not buy a certificate, but use the free Let's Encrypt

Answer 2

Good if translated correctly.
For landing pages, it's really easier to make Let's Encrypt.

Answer 3

For ledding, this nafik is not needed. Like most sites in general.
