If you’re wondering what your potential leads are up to, you’re not alone. A lot can happen in an internet minute, but opt-in advertising can help find the right sites to target the right people at the right time. Users are being pulled in multiple directions as they navigate the web, encountering ads, watching videos, conducting searches and scrolling through social feeds. The average user has five social media accounts and will spend five years of their life on these sites. Multiple open browser tabs and windows are the norm. And more than 270 billion emails are sent every day.
