How can I make my specific gig appear on the first page after someone searches for that gig ?
In this case, keywords can help you. When setting a gig in the 1st step in the last there are " tags " abd these are keywords. Put the tags that are mostly searched. I.e if you are a SMF Forum maker, then give it a key word like SMF , SMF Forum, simple machines, Forum designing etc… you can set only 5 keywords. When people will type these keywords your gig will appear on the 1st page. So think sharply about your gig that what people will type when they’ll need something that you provide.
