What's the ideal meta description length?

Roughly 120–158 characters. Google displays up to about 155–160 characters on desktop and a shorter amount on mobile, though — like titles — it measures pixel width rather than a hard character limit, so results vary slightly by font.

Does a meta description affect rankings?

Not directly — it isn't a ranking factor Google's algorithm scores. It affects click-through rate instead: a more compelling description earns more clicks at the same position, and click-through behavior is one of many signals that can indirectly influence how a page performs over time.

What happens if I don't write one?

Google will auto-generate a snippet by pulling text from your page content, often the opening paragraph or whatever text best matches the searcher's query. That's usually less persuasive and less consistent than a description you write intentionally for that purpose.

Can Google rewrite my meta description anyway?

Yes — Google sometimes replaces your written description with an auto-generated snippet if it decides page content better matches the specific search query. Writing a strong, accurate description still improves the odds Google uses it as written, especially for branded or exact-match searches.

Should every page have a unique meta description?

Yes. Duplicate descriptions across multiple pages give Google (and searchers scanning results) no way to tell the pages apart, and Google may simply ignore a duplicated description and generate its own snippet instead.
