If you have a company blog, it can be the best place to announce your webinar. Through blogs, you can target your audience by discussing how to register for the webinar and the webinar content itself.
Once you have recognized these leads, nurture them with follow up through various modes like emails, phone calls, e-newsletters, postal mails, etc.
Try to make a convincing invitation to drive registration. Don't give them a reason to feel like your invitation is a corporate "fill in the blank" form. Target a specific segment and make a personal connection, so you can retain them longer.
