Meta tag generator

Google cuts titles at about 580 pixels, roughly 55–60 characters, and descriptions at about 920 pixels, roughly 150–160 characters on desktop. The counters here measure the real pixel width, which is more accurate than counting letters.

Not directly. It is the text people read under your title in search results, so a clear description gets more clicks. Google sometimes replaces it with a snippet from the page that matches the search better.

They control the title, text and image shown when your link is shared on Facebook, LinkedIn, Telegram, WhatsApp and Slack. X (Twitter) reads them too, with its own twitter:card tag for the layout.
