well i did a test on all the social media sites using ebay as a model, yes they looked off facebook but no sales so i just stopped promoting on social media the views dropped but the sale where the same, i haven't done a test with ebid as the model as i didn't think it worth it after doing it in one place and it took me ages as i did one on each per day alternating the times and the lookers off each site put them on a spreadsheet and came up with the conclusion i was wasting my time and would be better spent listing.
