Use your content
I assume you already produce a lot of content for branding and marketing purposes. Maybe even a brand magazine. If you have a digital version, I encourage you to offer a digital download of it via registration, rather than just a free consultation on your website.
This is, for example, what our client Lulli has been offering on the Web for years. In fact, this is currently the 16th edition that the brand is making available via this system.

Optimize your events

You probably often organize events. Private parties, VIP presentations, etc. Of course, each participant must first respond to an invitation to indicate their presence at the event. Through these event registrations, do not hesitate to collect some data along the way . On their preferences, the ranges that interest them, their current needs. In order to justify the intention, organize a draw on those present to try to win an exclusive or personalized prize at the end of the event.
Second approach regarding your events: give away a few places to join the very select list of your guests. It's up to you to define the approach you want to adopt. Indeed, you can quite simply be satisfied with a draw among all the registrants. Or, you want to go a little further, like our client Lulli sur la Toile.
