How badly have marketers been hit by the pandemic? More than half – 55% — reported a budget cut, according to this Chief Marketer study. The marketing mix is also changing, with growth in social media, content marketing, influencer marketing, and email. Losers include search marketing, referrals, and, of course, live events.

The other side of customer tracking by advertisers is identity management by customers.

Companies can then verify identities based on the fragments, thus avoiding the risk of storing personal identifiers. Clever.
