meta.description-lengthThe meta description is too long or too short
Why it matters
"There's no limit on how long a meta description can be, but the snippet is truncated in Google Search results as needed, typically to fit the device width." In practice that is about 160 characters on desktop and fewer on a phone, so a long description loses its ending, which is usually the call to action. A very short one leaves most of the space under your link empty, or gets replaced with text lifted from the page.
Source: Control your snippets in search results. 70 and 160 are rules of thumb, not Google's numbers, which is why this is only ever a notice.
How to fix it
Write one or two sentences, 70 to 160 characters, with the reason to click first:
<meta name="description" content="Hand-made wedding cakes in Leeds, delivered and set up on the day. Tastings every Saturday: book yours." />
