I would like to promote my service (gig).Is it legal or not.So I can get best traffic and revenue.For this I want to hire someone who can promote gig on FB,Twitter,G+ and more places.
Fiverr encourages promoting your gig on social media. This is absolutely something you can do, and I recommend doing it. Just don’t start spamming groups and pages, giving yourself a bad rep.
Best of luck!
