First-Party Data Strategy: Why Ignoring It Is Your Biggest Marketing Mistake
As long as I have been in marketing, this has been my biggest concern, and sometimes, it is a pet peeve when having an honest conversation about what fails the discipline of marketing.
We all know first-party data is the foundation. This topic is boldly discussed at conferences and debated on panels year after year. Some even name their conferences after this theme.
Yet
While eighty per cent of marketers say data is critical, only thirty per cent are fully leveraging or building their own first-party data.
When Google announced the end of the cookie era, I felt that marketers would finally focus their efforts here, but even that didnโt move the needle for many in the industry.

โข Legacy systems, unclear ownership (marketing vs. Sales vs. IT vs. vs etc).
โข A focus on short-term ROI, like the CMO revolving door.
โข Assigning high value to third-party data when the actual untouched gold is your own data.

โข Data privacy regulations (GDPR, PDPA, CCPA) make 3rd-party data unreliable.
โข Third-party data is a band-aid solution or a quick fix; your brand deserves to own its own experiences on a great foundation.
โข Donโt get me wrong, third party can be an ally, but it canโt be the only trick in town.

โข AI/ML models are only as good as the data fed into them.
โข First-party data improves accuracy, relevance, and automation in campaigns.

โข Companies that lead in CX and data maturity will outlast their competitors. Although there is an outdated data point on this topic, I believe it remains a valid argument. Companies that invest in CX + FP data outperform the S&P 500 by 45%. Personalisation can drive a 5-15% revenue lift.
