Industry problems bg

Problems I solve

Typical Performance Marketing challenges I help with.

Each platform sees only itself

Google: ROAS 4.2x. Meta: ROAS 3.8x. Real after deduplication: 2.1x. You optimize on inflated metrics.

Scaling the wrong signals

Campaign A: ROAS 5x in Google Ads. Real: 1.8x (overlap with Meta). 45% of budget on an unprofitable campaign.

Cookie deprecation

You lose 30-40% conversion visibility. Platform algorithms learn from incomplete data.

8h a week on reports

Export from Google, export from Meta, manual merge in Excel. Time that could go to optimization.

30-45% of budget
That's how much may be misallocated due to lack of deduplication
