Increase eBay sales?

Hi

So I am selling a product on eBay, and I get an average of about 5 orders a day. Although I am very satisfied with getting some sales, I would like to get more of cause .
The only thing I just can't seem to get my head around, is how am I going to get more orders?
I know that people are buying the product I am selling, because I can see that my competitors quantity are going down on a daily basis.
My listing look very similar to theirs. The only difference between mine and theirs is that I am selling the product at the lowest price, while my competitors have more feedback than me, some of them are even "Top-rated".

Does being "Top-rated" and having more feedback, really make that much of a difference?

I had 100% positive feedback until a few days ago someone complained about something ridiculous, I have filled in a request to alter it, and even contacted the buyer. So I hope to get back up on 100% soon.

Can someone please share some tips and tricks, I can implement to get more orders, whether it is eBay SEO or something like that (if such things exist).

I look forward to hear from someone more experienced and knowledgeable than me

There is such a thing as eBay SEO (why do you always see the same sellers dominate some search results?).

But like Google, it depends on the category, the comp, and other metrics (page views? how many sales made in a particular time?, etc). What I usually do is look at the top ten in your nich/cat, and try to replicate some metrics.
