Our customers often see an ad on their phone, research on a laptop, and finally buy in-store or via a direct link. How can we move away from "Last-Click" attribution to something that actually gives credit to our top-of-funnel social media and video campaigns? We are looking for an attribution model that works across walled gardens like Google and Meta.

Last-click is definitely a relic of the past. In 2025, you should be looking at Data-Driven Attribution (DDA) or Marketing Mix Modeling (MMM). DDA uses machine learning to compare the paths of customers who converted versus those who didn't, identifying which touchpoints truly had the most impact. For cross-platform visibility, many firms are using "Incrementality Testing"—running "hold-out" groups where you stop ads in one region to see the true lift in sales. This is often the only way to prove that your "Awareness" campaigns on YouTube or TikTok are actually driving sales, even if they don't get the final click in your CRM.
Are you integrating your offline sales data back into your ad platforms using tools like Google’s Offline Conversion Tracking?
"Time Decay" attribution is a good middle ground if you aren't ready for full machine-learning models yet. It gives more weight to touchpoints closer to the sale.
Linda is right, but be careful with time decay; it can still undervalue the initial "discovery" phase that started the whole journey.
Christopher, we’ve started doing that for our high-value leads. We upload our hashed CRM data back into Google Ads so the algorithm can see when a "Lead" turns into a "Closed-Won" deal. It’s been a game-changer for our bidding strategy because we are now optimizing for actual revenue instead of just cheap lead volume. The next step is to get our retail partners to share their point-of-sale data so we can close the loop on our physical product sales as well.
