Yes i do, i started off in 2016, only listed maybe three thing and only made 4 sales between then and january 2017. Then i started listing more things, sorting out my tags and photos and at the end of 2017 ended up with 800 sales.
I've grown so much that i had to open a second shop to list just my wedding items as customers were finding it confusing wading through various other items to find the wedding stuff.
For advice i would say - tags are the most important, make sure they are relevant. Titles are also important, make sure some of your tags have the same words as your title
Add all the info you can in the description - 2 lines isnt going to cut it and you always get that one customer that asks questions that may be obvious to you but not to them.
Sell outside of the UK - my sales didnt start to rocket until i offered shipping outside of the UK but make sure you state in your description that you are based in the UK and that their items can take up to 3 weeks to arrive so that you dont get panicked customers messaging you 2 days after you've posted it asking where their item was and the fact that they didnt know you were based in the UK.
Photos - try to have at least 5, good lighting and at different angles - for some reason the amount of photos has an impact on the search algorithm.
Make sure you update your shop policies, your "about" page aswell.
Make sure your prices are right, do a search on etsy for similar things to what you make and ensure you arent pricing too high or too low.
Buy a light box - you can purchase them relatively cheaply on ebay, i have a small foldable box with an LED light, made a hell of a difference to my photos.
