for example: mr. visits example.com e-commerce site. views product goes product b , exits site. next day mr. see product b in right column/news feed ads.

i have hunch has firing custom audience pixel product b id data not sure how implement code in fb custom audience pixel.

also note: have configured product feed , product catalog work done.

i think it's funny facebook seems try outsource product support stackoverflow...

did have at

• https://developers.facebook.com/docs/marketing-api/dynamic-product-ads/product-audiences/v2.3

you need use custom audience pixel described at

• https://developers.facebook.com/docs/ads-for-websites/website-custom-audiences/getting-started

with events described in first link. e.g. upon product view in website, product view content event should triggered:

window._fbq.push(['track', 'viewcontent', {   content_ids: ['<product_id>'],   content_type: 'product' }]); 

you should able build custom audiences ads.
