Meta description

The short summary under a result's title, which doesn't affect rankings but strongly affects click-through.

In depth

What it really means

A meta description is the short snippet of text search engines can show beneath your title in the results. It is not a ranking factor, but it is sales copy: a compelling description earns more clicks from the same ranking.

Google often rewrites descriptions to match the query, so write a strong default but expect it to vary.
