I've started my shop by only selling the "A" size variations and I'm wanting to add the 2:3 ratios Is there any way to add these in bulk on Etsy or do I have to now add them individually to all my listings?

First orders completed absolutely buzzing Many thanks to @Tom Beeston And @Mihai Volintiriu for answering my 16363 questions haha

So from the looks of it Etsy may be changing the way they prefer listing titles to be. I've had them suggesting me to use their new AI tool to improve the titles for my 1000+ listings but from the examples its shown me they just don't seem as detailed or key word heavy as my own. It looks like they want to move customers into having more minimalist titles but this seems less competitive and I can't see how this wouldn't just hurt my sales. Has anyone got any ideas on this/how are you guys approaching the change? I'm nervous to change all my titles as if it screws up my engagement I dont have them all copied somewhere else rn. The notification saying my 'search visibility' is being impacted is annoying me too lol.

I am aiming to create 5 new designs every day so i can build a portfolio of listings. From someone with experience am i better stacking up my designs to drop in bulk or list as i go. As well as that for advertising is it worth starting my advertising as soon as i list my 1st product or wait till i have a sufficient amount of products to sell before starting my campaign. Any help would be appreciated.

Hi guys Received my first order this morning Ordering on the portal was mega easy with my Etsy shop linked, pretty much an automatic process Just wanted to say thank you for everything so far
