Has anyone come up with a simple solution to add to Lead Scoring if someone follows your Twitter page? Obviously complexities exist in determining e-mail address and linking them to Marketo lead e-mail etc.
You will need some 3rd party solutions to do this, or a dev that links Twitter API with Marketo's. And even though I am really not sure the Twitter API would enable you capture the email, making it quite hard to reconcile with the Marketo entry.
Grégoire Michel's right on this. Like it or not, Twitter sunsetted their Lead Generation ads in February. He is also correct in his assumption - the Twitter API does not allow for email capture. Unfortunately the 'out of the box' third party solutions which connect Marketo with Twitter either require a email to go into Marketo or a Twitter username to query twitter. The only solution is to setup a specialized integration that, upon a new 'follow' on Twitter, looks up matching information based on First Name/Last Name/whatever else you specify, and, if it finds a match, then changes scoring for the Lead accordingly. It looks like there are third party providers out there that can do this.
