Valide sua tag de título e meta descrição por contagem de caracteres E largura em pixels — a métrica que o Google realmente usa para truncar snippets. Inclui uma pré-visualização SERP.
Use the SEO meta length checker on every page before publishing. Both title and description should fit the SERP layout cleanly — too short wastes space, too long gets truncated with an ellipsis.
Character-only counters miss the truncation rule (Google uses pixel width). This tool combines both metrics so you can defend either to a stakeholder.
Google truncates titles and descriptions by pixel width, not character count. Arial-ish fonts mean E and i are narrow, M and W are wide.
This tool combines character count with a pixel-width estimate calibrated to Google's snippet font, and shows a SERP mockup so you can preview the truncation.
Mobile and desktop use different widths; toggle the device selector to see both.
Google rewrites titles based on the search query and what it thinks the user wants. Your tag is a strong suggestion, not a guarantee.
Pixels. Google truncates by visible width, so a description full of "iiiii" can fit more characters than one full of "WWWWW".
Mobile is narrower. Titles: ~520px mobile, ~580px desktop. Descriptions: ~860px mobile, ~960px desktop. Test both.
