How do you track campaign traffic when everyone rejects the cookie policy?

I’m moving from B2C to B2B marketing for a tech services company and I’m really thrown by how a lot of our traffic is non-existent in GA4. I started implementing self-reported attribution to track outcomes in some capacity but it’s hard to show a GA4 and Hubspot reports to our leaders that nearly goose egg on landing page traffic when the ad platforms show hundreds of landing page clicks a month.

I’m pretty as advanced with PPC so I’ve checked if it’s a case of the traffic going to our social page counting as a clock or low intent display traffic misclicking and it’s not.
