Segment is overkill when you just want Meta and Google to work
Problem: A developer gets asked to 'set up tracking for Meta and Google Ads.' They Google it, find Segment, spend 3 days setting it up, and get hit with a $120/mo bill for a tool designed for enterprise data teams.
The CDP trap
Segment is a phenomenal Customer Data Platform. If you need to route event data to 200+ destinations, including your data warehouse, CRM, and email marketing tool, it's the gold standard.
But if your goal is simply to tell Facebook and Google that a user signed up or bought a product, a CDP introduces massive latency, complexity, and cost.
No native ad specs
CDPs are generic data pipes. They don't natively map to the very specific quirks of ad platforms. Meta wants `CompleteRegistration`. Google wants `sign_up`. LinkedIn wants a numeric conversion rule ID.
With Segment, you still have to read the ad platform documentation and write custom mapping logic.
The SDK alternative
A purpose-built ad tracking SDK abstracts away the ad platforms. You pass a canonical `SignUp` event, and the SDK knows exactly how to format it for Meta, Google, LinkedIn, TikTok, and Reddit.
You get the clean developer experience of a single SDK without the bloat, cost, and complexity of an enterprise CDP.
Key takeaways
- Segment is for data teams routing to hundreds of tools; it's overkill for ad tracking.
- Generic data pipes force you to learn specific ad platform specs.
- A dedicated tracking SDK is cheaper, faster to set up, and built for developers.
