Deep scanning is a term we use to search connected sites for email contact information. If site A (Dog Food Manufacters), links to site B (YummyDogFoods.com) and Site B links to site C (HealthyDogFoods.com) and site C links to site D (Ultimate Dog Foods). We crawl all these connected sites up to 5 levels deep, looking for email contact information. If you sell, dog food manufacturing equipment, you might be able to generate additional outbounds leads from deep scanning. All email contact information will be shown with a link to where the email was found, so you can visit that page to gather more information and to determine if it's a lead you should reach out to. There will always be unrelated leads, because sometimes sites link to unrelated sites. But we try to eliminate those sites from being scanned during deep scanning like "facebook, twitter, linkedin, etc."
