I think it is time to take advantage of the huge community on Linkedin A lot of my sales have come from there. It would make easy for buyers to also share the gigs that they like.
Why not just use the same share tool that is above you could just click the + icon and choose linked in or any other type of social media.
I haven’t really found a way to market my gig on Linkedin, I use that site mainly for the FIVERR forum
I promote gigs on my own website where I’m able to utilize more share buttons. LinkedIN is a great place to market services if its done right.
