What it is
An attribution model is the framework that determines which marketing touchpoint gets credit for a conversion. If someone first found you through a Google search, then saw a Facebook ad, then clicked an email and booked — who gets credit? That depends entirely on which attribution model you're using.
Why it matters
Attribution determines where you invest your marketing budget. If your attribution model is wrong, you'll over-invest in channels that look good on paper but aren't actually driving decisions, and you'll underfund the channels that are doing the real work. It's one of the most consequential — and most misunderstood — concepts in marketing analytics.
The mistake most people make
Defaulting to last-click attribution without questioning it. Last-click gives 100% of the credit to the final touchpoint before conversion, which makes it look like Google Ads is everything and ignores the blog post, Instagram follow, and email that got the person there in the first place. The customer journey is rarely one step.
