A meta description is the short paragraph of text that often appears under your page’s title in search results. It does not directly affect search rankings, but it is usually the deciding factor in whether someone actually clicks your result instead of a competitor’s.
What happens when it’s missing
When a page has no meta description, search engines generate one automatically by pulling text from somewhere on the page. That auto-generated snippet is frequently awkward, out of context, or unrelated to what actually makes the page worth visiting, because it was never written to summarize anything — it was just the first text the algorithm found.
Length matters too
- Summarizes the specific page, not the whole site
- Stays roughly 70–160 characters so it isn’t cut off in the results
- Gives someone a reason to click, not just a description
