I am a new born seller just 1 month passed and only 1 order completed. Today I can see my 4 different gigs at first page. I believe its possible for proper SEO. In this position, How much response or order I can expect?
An impossible question to answer, as you deliver orders and gain more good reviews listings change their position. It just depends on what the buyer is looking for. Sometimes they will scroll through the whole lot or just go for the first one they see. Orders are like buses, you wait ages for one then 3 turn up at once. Patience is key.
