Measure Instagram / Facebook ads — see which campaigns bring sales and at what cost per order.
Retarget cart abandoners — build an audience of people who added to cart in the last 7 days but didn't buy, and show them an ad (maybe with a COD-available message).
Lookalike audiences — let Meta find people similar to your buyers.
Advantage+ / sales campaigns — Meta optimises for the Purchase event, which needs the pixel.
Dynamic product ads — show people the exact products they viewed (also needs a product catalogue in Meta Commerce Manager).
