The example below is from DesignR and illustrates how you can personalize your homepage for referral traffic coming specifically from review websites. In this case you can see that the headline has been changed to mention Capterra while the CTA buttons have also been adjusted for a visitor who might be further down the funnel. This is why instead of a trial they suggest booking a demo or contacting someone from the team. Another neat addition is the star rating on the right corner which adds a visual element too.
