Retargeting Fundamentals: What Beginners Should Understand
Retargeting is often described as one of the easiest ways to increase conversions.
It can be effective, but it is not automatic.
What is retargeting?
Retargeting means showing marketing messages to people who have already interacted with a business.
Examples include:
- website visitors
- product viewers
- video viewers
- social media engagers
- previous leads
Think about the audience window
Someone who visited a product page yesterday is not necessarily in the same situation as someone who visited three months ago.
Different time windows can represent different levels of intent.
Exclude people who already converted
If the goal is acquiring new customers, existing purchasers may need to be excluded from acquisition audiences.
For retention or upselling campaigns, previous customers may be exactly the audience you want.
Change the message
Retargeting is an opportunity to continue the conversation.
A cold audience might see:
"Discover our project management software."
A person who already visited the pricing page may be more responsive to:
"Still comparing project management tools? See how the workflow works."
Watch audience size
Very small retargeting audiences can become expensive or saturated quickly.
Monitor frequency and performance over time.
Conclusion
Retargeting works best when it reflects the user's previous interaction. It should not simply show the same advertisement again. Use behavioral context to make the next message more relevant.
