Assign Member Group to Search Engine Bots/Spiders?

[M@tthew]

Hi everyone (this is a great forum, good to be here!).

I've recently converted one of my forums from IPB 2.2.2 to vB 3.6.5 and loving it!

On IPB, it was possible to assign and set a configured user/member group which we could force all Search Engine Spiders/Bots to use.

This was very convenient as even though Guests may not have been able to read parts of the forum and topic content, we could allow the bots/spiders to read it, with positive results in search engine results.

Now I know vB doesn't do this by default, so apologies if I've missed any mods, but is there a modification/add-on/plugin available here to recreate this?

Many thanks in advance.
