This comes from the last few weeks of researching stores and finding out what works
Although I'm not an expert, I analysed a lot of Redbubble stores along the way, some of them with HUGE earnings, and I learnt these 7 things:
1. Using your store name as a Redbubble tag
2. Branding – Your banner should have your best selling products on it
3. Don't use Redbubble product optimization – Put them all on t-shirts (video coming – I guess it depends on your branding of the products though)
4. Make sure your designs are legible on mobile – right click inspect and see it
5. Set up Google Analytics (video: https://youtu.be/2YNY5Ur-BHE
6. Set-up all your Social Media profiles and put a link to your redbubble store on every single one
7. Don't use too many tags/don't upload too many designs a day
If you do these from day one – you are ensuring to maximise your redbubble profit and sales potential
