Stop flying blind in performance marketing:

How CRM/AdSync makes the real value of your campaigns visible — and why this is the game changer for data-driven growth

Introduction: The true performance of your campaigns is not in the Ad Manager

Anyone who generates leads today via paid channels such as Meta, Google or LinkedIn usually receives impressive dashboards: click rates, conversions, CTRs, CPAs, reach. But behind all these metrics, the most important information is often missing:

Which leads become actual customers — and how much revenue does this generate?

This is precisely the central weakness of traditional campaign evaluation. The result is marketing that is based on intermediate goals — not on final results.

And that is exactly why CRM/Adsync Not a “nice-to-have”, but an essential tool for companies that not only want to measure performance, but really want to control it.

Marketing reality: Lots of leads, few deals

Most ad campaigns aim to generate leads — often through forms, downloads, test requests, or demo registrations. These contacts are then handed over to sales. What happens afterwards, however, often remains obscure:

  • Are the leads being processed?
  • Which campaign delivered the best SQLs?
  • How many deals were created per source?
  • Which ads really generated revenue?

Marketing therefore works with superficial positive numbers, while sales deal with unqualified leads — or good contacts can't be attributed.

The solution: The systematic combination of CRM data with campaign performance.

What does CRM/Adsync mean in practice?

CRM/Adsync means the automated connection of your customer relationship management system with your active advertising campaigns. The aim is to create a seamless flow of data — from the initial interaction to the conclusion of a transaction.

In concrete terms, this means:

  • Each lead is uniquely assigned to a campaign the first time you contact us (e.g. website form).
  • As soon as the lead gets into CRM, the original campaign source is retained.
  • With every movement in the sales pipeline (e.g. “opportunity,” “negotiation phase,” “won”), this information is fed back to the tracking.
  • Sales data from CRM is automatically correlated with ad data — and this results in a genuine, resilient ROAS calculated.

From MQL to Revenue: The Decisive Difference

In classic ad reports, you can see that campaign A generated 75 leads. But what you not see:

  • That of these 75, only 12 were contacted by sales
  • That only 4 of them showed genuine intent to buy
  • That 3 of them were even integrated into CRM
  • That just a deal over 4,800€ was completed

The original ROAS looks impressive — but the real business effect is modest.
With CRM/Adsync, this reality becomes visible. You don't rely on superficial lead numbers, but on the development of your pipeline — right down to sales.

Why classic ROAS is often deceptive — and what counts instead

ROAS (Return on Ad Spend) is classically calculated as:

Turnover/advertising costs

However, in most cases, this calculation is based on hypothetical revenue (e.g. lead volume × average value). In CRM-based campaign assessments, the following happens instead:

  • Revenue is based on real deals, not assumptions
  • The time of revenue is taken into account (time-shifted attribution)
  • You can see which ads valuable customers bring — and which only deliver “fill leads”
  • You get a dynamic ROAS that grows with your pipeline

The result is a realistic, controllable model for campaign optimization.

Linking ad campaigns with CRM: Why this has rarely been done so far

Many companies want to connect their CRM and campaign data — But in practice, it fails at several points:

  • Technical complexity (APIs, data mapping, attribution logic)
  • No clear ownership between marketing and sales
  • Complex manual data maintenance
  • No real-time data, no automation
  • Lack of tools that make the process simple and GDPR-compliant

This is exactly where LeadMetrics comes in CRM/Adsync to: The platform automates the entire reconciliation between CRM and ad data. The lead is correctly identified upon initial contact and transferred to your CRM with the right campaign context. Sales, status and deal stages are constantly updated — completely without Excel exports, developers or interim solutions.
