There is probably no one correct answer.
I can tell you what has gotten some of my listings to come up.
For example, at one time I was selling an aluminum license plate for the NCAA college Slippery Rock University. Yeah, I know - I never heard of them either. But the school exists and has some graduates. But when I did a Google search there were absolutely NO results. Because no one else had them.
That was good enough for me. I bought a dozen and listed them.
In due course if you did a Google search for them my name not only came up, but it was the first name on the first page. Every e-tailers dream. It was also the first item on their image pages.
They sold out within a month. Once the first buyer found them they no doubt told their former classmates “Guess what I just found”. I also got a lot of sales for my other NCAA plates.
So the lesson I learned is you have to have something that no one, or at least very few others, have. I have over 10,000 listings. I have made it a point to be sure that I have some unusual designs even in common items.
Just remember there are a gazillion others out there also trying to be on Google. If you are offering the same things as them you are swimming upstream. Everything may not come up, but if enough things do from time to time your name becomes known.
