MeshLine
A practical example
Example: before launching, you compare a 'frequent buyers' segment with a 'high LTV' segment and find 60 percent overlap, so you merge them and redirect the freed budget to true prospecting.
What to evaluate before investing
- Check whether overlap is computed on resolved identities or raw platform IDs, since the latter hides cross-channel duplication.
- Verify you can analyze overlap across platforms, not only within one ad account.
- Look for actionable output: suggested exclusions or merges, not just a percentage matrix.
Limitations and tradeoffs
Overlap percentages are only estimates; platform-reported reach uses different identity graphs and cannot be summed precisely. Use overlap to guide structure, not as an exact deduplication guarantee.
