If you share the gig on social media, the gig impression clicks will definitely increase but it will not benefit your gig. Because if there is no order with impressions, clicks and more then it will be proved that your gig is not acceptable to the client so the order is not coming. As a result, your gig will no longer be found in the search. So my advice is to create a sco optimized gig with low competition key words without sharing.
