Proven Results!

Here’s a great example of a successful campaign we ran with Crimestoppers, who are independent charity that allow people, to speak up about crimes they’ve witnessed or are aware that are going on in their area. This is all done through a phone line or via email, but always 100% anonymously.

Smart Digital Network were delighted to feature a standalone campaign by Crimestoppers across our entire D4 and D6 network throughout Jun/Jul 2022 to encourage people to report violent crime

Campaign Outcome:


Uplift in reports to Crimestoppers line

(July v May 2022))

“The results from over the summer have been very encouraging.”
