replacement with <!--VBSEO_RR

Hello All
I saw this question was asked many times but without a definitive answer, so I try again:

where is the best place to put <!--VBSEO_RR_2--> and <!--VBSEO_RR_3--> replacement?

I'm using vbseo style 1.0

regards
Manuel

They are optional. Use them if you want to, otherwise they are not necessary to be used.

ok but if I want to increase its effectiveness, where you can use them?

If you have to ask this, you don't NEED them


We used to use RR 2 on titles. Not sure if that is still the case on vb4.
rr3 was never used.
