Check description length, truncation and keyword use before it reaches a results page.
The content attribute of your description meta tag
Optional — query terms appear in bold in the snippet
Paste a meta description to see its width, where it would be truncated, and any issues.
Meta descriptions are not a ranking factor — they influence whether someone clicks. Google also replaces them with its own extract from the page for a large share of queries, so treat a well-written description as improving the odds rather than guaranteeing what appears. Widths here are approximations, not measurements of Google’s rendering.

Cut off mid-sentence
This is an extremely long meta description that keeps going well past the point at which any search engine would stop displaying it, wasting the effort spent writing the rest of the sentence entirely.Too vague
Says nothing specific

Query terms get bolded in the snippet, so their presence is worth checking.
Width, truncation points and issues, separated by severity.
Mobile snippets are narrower than desktop ones, so a description can be intact on one and cut on the other. Both limits are checked.
The guidance treats the description as ad copy — which is what it is — rather than as a ranking factor it has not been for many years.
Google often substitutes its own extract from the page. The tool says so rather than implying your text is guaranteed to appear.
Analyse a meta description for the things that actually change how it appears: rendered width against the desktop and mobile snippet limits, character count, and whether your focus keyword appears — which matters because Google bolds query terms inside the snippet, and a bolded phrase draws the eye. Descriptions do not influence ranking directly; they influence whether anyone clicks. The tool treats them that way, and it is clear that Google replaces descriptions with its own extract for a large share of queries.
