Hi, I have a similar conversion rate. It’s not something I worry about particularly but I have thought about doing the following and based on the results I would do experiments with my titles, images, descriptions etc. The only thing that has stopped me doing this is the fact that I am quite happy with my number (and value) of orders at the moment. This would take some time and a lot of trial and error and I have had to turn away some sales due to the amount of work I get from repeat clients so no point in messing with my gigs just now.
Assessing where my impressions are coming from - are people searching for something other than my gig and I am showing up?
What is my impressions to clicks rate? If I show up in results a lot but get few clicks, should I change my title or image?
If I am getting lots of clicks but few sales then there has to be a reason. It could be price, presentation or maybe a mistake in the description that stops people.
With regard to average sale price, this will vary from seller to seller. My average sale price is double yours but I focus on larger size orders and so I get very few orders of less than $20. You could do 10 times the number of orders that I do and make much more money even though your average is lower.
As miss crystal says just look at your bottom line.
