Yes it will.
Certs are so much of a fucking scam I'd bet a jew came up with the idea for them. SSL certs are an almost TEN BILLION dollar market and they constantly tell you how they're junk yet every site is required to have one or they're inaccessible or get painted with half a dozen warning notices.
Is the public really getting ten billion dollars worth of value out of this shit?
For most sites that just present content, I'd say there's limited if any value. For what I do, which is maintain an old school website with no interactive anything, there's zero value. But I need one otherwise you can't even see my stuff.
