What is Meta Description?
The HTML summary of a page. Rarely a ranking factor, but a parsing aid for machines and the pitch that wins the remaining clicks.
Definition
A meta description is the HTML tag summarizing a page's content. Google rewrites most of them, and it isn't a ranking factor — but it remains the default snippet in many contexts and one of the first things any crawler, including AI bots, reads about the page.
Why it matters
In a zero-click era the snippet is your pitch for the clicks that remain, and for AI crawlers a precise meta description is a cheap comprehension aid: a one-sentence machine-readable statement of what the page answers. Write it as the direct answer to the page's core question — the same discipline that improves retrieval quotability improves the tag.
Frequently asked
Do AI systems read meta descriptions?
Crawlers ingest them along with all head metadata. They won't rescue weak content, but an accurate description reinforces topical signals and often becomes the fallback summary in link previews and answer cards.
What's the ideal meta description in 2026?
One or two sentences (~150–160 characters) stating exactly what the page answers or provides, front-loading the entity and topic. Skip superlatives; machines quote facts.
