Can any one help me by inform that
What way is better to rank my gig on first page.
There is no such way to do this.
Nowadays there is a random rotation of gigs on first page, so if you want to make this to first page of BEST SELLING, you need to deliver high rated orders, and you may have the luck to get this in the first page.
If you want to get this in first page of RECOMMENDED or RELEVANCE tab, you will need to set higher prices in your gigs, but this is not guarantee of sales. You will also need to be lucky to get there
Thank you xuntes for you advise
