Just wondering how to get around the problem of hiding website
content to a general visitor but allowing it from a back link from
an email.
I was thinking the email would have a link of mysite.com/page.php?hidden=show
Which could show the hidden content on the page only for the email recipient
You could put a ?code=123467890 on the end of the url in the email,
which must be of a php page. The php can then check if a value is
given to ‘code’ and if it’s correct it can then read and send out the
hidden page segment from an external file - or not.
The name probably shouldn’t be ‘code’, but something more obscure,
and the number should be big-ish so people don’t bother trying to get
a meaning from it if they notice it. Even better if it’s in
hexadecimal. If emails are individualised then the number could be a
different multiple of some other big-ish number. The php would check
if the code is a multiple, do the division and you know who
responded. The included page segment should have a filename extension
that the web server won’t serve.

Thanks David,
The email url can’t be very complex the client who is setting the url by hand.
I see the issue is if the page changes would are being served via a GET URL for the same content (with slight change) then it’s a URL google would probably detect this.
So i think I need a way if hiding the URL from google.
