I am not really against gig marketing, though it is true that impressions, clicks, favs without order is downgrading, but it is ok for a while as we are doling that to get attention of the sellers.
there are lots of gigs with good SEO, good title of description or image, but they still don't get orders. in that case I think it is ok for a while todo gig marketing.
if it brings you clients, why not?
