More repeat visits from guests who already found you.
Much of the guest relationship sits with third-party apps, and the guests who browse your menu or call without booking are gone. Repeat visits are where the profit is, and you can't invite back people you can't name.
Bituser turns visits to your site and calls to your lines into a guest list you own. You bring guests back by email, ads, and mail on your terms, and you depend less on platforms that own the relationship for you.
