We have recently updated our Link Generator with a new promo option. The 7 days PRO trial link that was previously available was replaced with a 7 days GURU link. This means that you can now refer your audience to this advanced plan, and allow them to try out some advanced tools such as Historical Data and Position Tracking Multi-Targeting.
To collect your 7 days GURU trial link, go to the Link Generator page and select the 7-Day GURU Trial option.
If you want to learn more about GURU subscription and its benefits, please refer to this article on SEMrush's Knowlege base.
