The reality of GDPR has made data privacy a hot topic these days. California will soon implement similar policies, and it’s likely other states will follow. So how do you make the most of the data you have, while still safeguarding the privacy of your customers and leads? Opt-in advertising for lead generation. The key lies in encryption and the use of hashed data to build an efficient email list. It’s a win-win: you keep your customer data safe and secure, and in doing so, provide yourself with a method of lead generation that’s more efficient and cost-effective than anything else out there. Here’s how opt-in advertising for lead generation works:
Encrypting Known Customer Data With Opt-In Advertising for Lead Generation
First, we take a list of known customers (or leads) and encrypt the data using MD5 hashing. This ensures that no one else sees the actual email addresses on your list, allowing you to maintain full data privacy. But the way MD5 works means that the hash is unique to each user; this one-way encryption is always the same for the same email address. For example, firstname.lastname@example.org always equals abcdefg. This allows two hashed lists to be compared anonymously to find duplicates, without revealing any personal information. This provides a safe way to compare users across databases and platforms as we launch an opt-in advertising campaign for lead generation.
Pre-Screening Partners for Known Users With Opt-In Advertising for Lead Generation
Since many people are signed in on devices and often even partner websites, we know who most users are. With opt-in advertising for lead generation, we take advantage of this information and combine it with known customer data to pre-screen for users already in your database, without ever compromising data privacy. In advance of serving a lead generation ad, we ping the advertiser’s list with a hashed version of the on-site user’s email address.
Targeting Opt-In Lead Generation With Opt-In Advertising for Lead Generation
This pre-ping instantaneously sends back a decision regarding ad serving. We query the database to see if the email address is already there. If it is, we don’t serve the ad, as this would be a wasted impression to a known user already on the email list. However, if the email does not appear, we will serve the ad, as this user is not currently signed up but represents a good fit for our target audience.
Pre-pinging the database saves money, ensuring you only pay for truly new users not currently on your list. There’s no chance of duplicate emails being added to your list, making opt-in advertising an efficient lead generation strategy. You’re guaranteed to accept every new email address added to your list, and there’s no wasted impressions or sign-ups on existing users. Your Cost Per Lead goes down, while your quality goes up, creating a cost-effective lead generation strategy.
