Meta Description Counter

Google truncates by pixels, not characters

The familiar 155-character guideline is a rough proxy. What actually happens is that Google renders the description in a specific font at a specific size and cuts it when it exceeds roughly 920 pixels on desktop and around 680 on mobile. A description of 155 characters made of narrow letters fits comfortably; the same count in capitals and wide characters is cut short. Counting pixels is the only way to know.

The description does not affect rankings

Google has stated repeatedly that meta description is not a ranking factor. It affects click-through rate, which affects traffic, which is the thing you actually wanted. Writing descriptions to please an algorithm is wasted effort; writing them to make a human choose your result is not.

Google rewrites most of them anyway

Studies consistently find Google replaces the supplied description on the majority of queries, generating a snippet from page content that better matches the specific search. This is not a failure: a query-relevant snippet usually outperforms a generic one. The description is a strong default for when the query is ambiguous or the page is shared on social platforms that do use it verbatim.

What makes a description earn the click

State what the page gives and why it is worth choosing over the nine other results. Include the primary query phrase, since matched terms are bolded and bolding draws the eye. Front-load the substance, because the tail is what gets truncated. Avoid restating the title — the two appear together and duplicating wastes the only two lines you get.

Empty is worse than imperfect

A page with no description gets a snippet assembled from whatever text Google finds first, which is often navigation, boilerplate or a cookie notice. That is materially worse than a mediocre written description. Every indexable page should have one.

Duplicates across pages are a signal of thinness

Identical descriptions on hundreds of pages tell a crawler the pages are interchangeable. If writing a distinct description for each page is genuinely impossible because the pages are near-identical, that is a content problem the description cannot fix, and consolidation is the real answer.
