Hyde here from Shopify. Great question!
Congratulations on what you've achieved so far. It looks like you're using one of our free themes. Did you know we have help documents for each theme here?
Have you stumbled across our Tools page yet? It has a lot of resources for a merchant just starting out, including an image resizer, a logo maker, a pay stub generator, a shipping label template, and a profit margin calculator… And a whole host more!
Center aligning images and text should be fairly straightforward as we have a center-align option, which I've used in this video https://screenshot.click/20-05-7pyq8-450kj.mp4.
When I was on your store I noticed you didn't have your favicon set up. This is a really cool feature and it makes the page look a lot more trustworthy and professional. The favicon is the little logo you see in the tabs on your browser.
You can add your own logo to your store in the theme editor by going to Theme settings > Favicon here:
Also, don't be afraid to get really creative with your product descriptions!
There are even some templates you could use to speed up the process.
Perfect for ___________________________ (ideal situation),
these _______________ (product name)
can be/will _______________ (tell a quick story).
(Product name) ______________
are ______________ (top features)
to _______________ (product benefits).
No more _____________________ (pain and/or challenge).
Perfect for weekend getaways in the mountains, these Mighty Camper Cups will bring you and your friends or loved ones closer together around a campfire. Exactly what mountain trips were made for! Our Mighty Camper Cups are sturdy and built just for you with insulated fibers to ensure that your hot cocoa stays hot and your iced tea stays iced. No more crying over spilled milk!
You can also take the keywords here and add them to a spreadsheet so Brand, Baseball Cap, Men, Cotton, Casual, Sports, Golf, Hats, Snapback, etc as you add products you can see which of these come up most often and use them for your collections Meta Titles and descriptions also.
I hope this all helps!
All the best, Hyde.
