Yes, thank you. That was referenced above, and as I said, I'd read all of that.
As far as I can tell, there's nothing definitive in any of that. As incredibill said in that post you linked to "I wouldn't use the following AS-IS without a bit more work".
And again, not being a coder, I don't even know what "a bit more work" refers to. And that post was written 5 years ago and so much has changed with the spiders, mobile, etc. so I'd imagine much of what it talks about is out of date anyway.
So what I was asking is if there's the exact code, scripts, etc. that I can copy/paste into my site and have it work. Plus some instructions for what exactly needs to be done.
Sorry, it's all beyond my knowledge base. I tried to hire someone to do it but couldn't find anyone that knew how to do it.
