Conversion Attribution
Conversion attribution is a method of assigning value to a conversion across the marketing channels and touchpoints that influenced a user’s decision to complete a desired action.
What is Conversion Attribution?
Users rarely make a purchase decision after a single interaction. They might see an ad, click a link, return via search, subscribe to a newsletter, and only then place an order. Attribution helps determine the contribution each channel made to the final conversion.
Without correct attribution, it’s difficult to understand which sources are truly effective.
Why is Attribution Needed?
- Evaluating channel effectiveness
- Optimizing advertising budget
- Reducing customer acquisition cost
- Correctly allocating investments
- Understanding the true customer journey
- Eliminating bias in analytics
Main Attribution Models
- Last Click. All conversion value is assigned to the last channel before the purchase.
- First Click. The conversion is attributed to the first interaction source.
- Linear Model. Value is distributed evenly across all touchpoints.
- Time Decay. Channels closer to the purchase moment receive more weight.
- Position-Based Model. The highest value is assigned to the first and last touchpoints.
- Data-Driven Attribution. Algorithms analyze real data and distribute value based on statistics.
Where Attribution is Used
- In advertising platforms (Google Ads, Yandex.Direct)
- In web analytics systems
- In CRM
- In end-to-end analytics
- In performance marketing
- When building CJM (Customer Journey Map)
Common Mistakes
- Using only the “last click” model
- Ignoring a long sales cycle
- Lack of integrating online and offline data
- Incorrect event tracking setup
- Absence of a unified analytics system
Summary
Conversion attribution allows you to see the real impact of marketing channels on sales. Choosing the right model helps allocate your budget more effectively and increase marketing ROI.
If you ignore attribution, you might turn off a channel that is actually driving sales.
