Today's Shopify tip might sound super basic but in the past few weeks, I've seen several stores missing even something this basic.
Every webpage should have one and only one HTML <title> tag. That tag heavily influences Google's ranking and can be used by them directly in the search results.
A quick test is to open your store in a browser and check that the text shown in the browser tab is actual text and not just the browser url.
Sirius Cybernetics Corporation is correct, while https://example.com is wrong.
If it's showing the latter, your tag is messed up.
Every theme I've seen comes with it by default so there's a good chance that some app you uninstalled wiped it out or lost it due to a coding error. If that's the case, talk to your theme developer and see if they can recover it for you.
If you'd like a structured data app that follows Google's guidelines and is more effective than the rest of the industry at winning Rich Results, you'll want JSON-LD for SEO.
It also doesn't touch your <title> tags like other apps so there's no risk of losing them.
