Easy way to improve CPR (through small on-site change)
After getting a potential lead on to your website (be specific/highly wary when using website click optimizes campaigns-due to record levels of Meta fraud and false reporting/fake clicks), a great way to ensure you maximize lead retention and lower your CPR (form submission, or booked consultation) is to implement a pop-up video from the owner.
This can be a very basic video but as long as it shows the owner and gives a quick authentic message to the user ("I see you clicked... we're fully local, ensure our own installs, etc."), this has drastically improved results and thus begins creating at least semi-warm leads that you can route into solar campaigns.
