Can web cookies still be used post-GDPR? If not, what should I change to?

In our GDPR Q&A series we get answers from experts to your burning questions about data regulations and compliance.

To answer  the question, cookies will always be present in web access because of the function they perform in the browser, but in regard to the use of third-party cookies — the ones typically used in the delivery of advertising — publishers that are reliant on the revenue they bring generally don’t know that much about their visitors anyway, as they lack registration data that would bring them into PII territory.

This is where the EU is being a tad heavy-handed through its own ignorance, but rather than writing a big letter, publishers should really be focusing on other data sets that can dramatically improve their advertising offering.

One of the key aspects around GDPR is the acceptance of a "contract of consent" between consumers and advertisers. Prior to and during the booming growth of programmatic and dramatic scale of internet access, the industry should have really maintained a permission-led approach anyway as it’s a positive action that creates a closer bond with the consumer.

Publishers must look ahead and create a more open, transparent relationship with consumers if they want the kind of data and insight needed to compete with the duopoly.  

The knock-on effect of this is a better, more relevant advertising experience for consumers, that can help negate the potential for big fines on advertisers and publishers, reduce the future potential for further harsh measures around data protection, and ultimately safeguard against Google and Facebook getting an even bigger chunk of ad revenue.
