Title tags not displayed on Google

[UnlockHomes]

Hi all,

I've been noticing my shop's title isn't being display on google searches, neither is it shown in the "tabs" section of my browser.

Running a site audit on Ahrefs shows I have a lot of pages without a site title. However, every page does indeed have a <meta property="og:title" content=""> tag and a <meta name="twitter:title" content=""> tag (not sure what the twitter one is.)

On google it just displays my store name, and on the tabs section of my browser its just the URL.

What is the problem here? Should I add/change it to a <title>Preferred title goes here</title> tag instead?
