a11y.page-titleThe page has no title to announce
Why it matters
The <title> is the first thing a screen reader says when a page opens, and the only thing it says when someone flicks between tabs or windows. Without one it reads the address, or the file name, and every tab of your site sounds the same. It is also what a sighted visitor with twelve tabs open is looking for.
The title should say what this page is, before it says whose site it is: "Wedding cakes · Flour & Co", not "Flour & Co" forty times.

How to fix it
Give every page a <title> of its own in the <head>:
<title>Wedding cakes in Leeds · Flour & Co</title>In a single-page app, set document.title when the route changes, or a screen-reader user never hears that the page did.
