It is ad copy, not a summary
Descriptions do not affect ranking. They affect whether anyone clicks the ranking you already have, which makes them an advert for the page rather than an abstract of it.
Free tool · No signup
Free meta description generator
Five search snippets for any page, each written to fit the 155 characters Google shows and to earn the click rather than describe the page to itself.
Make it count
What a meta description is actually for.
Stay between 120 and 155 characters
Shorter wastes the space you were given. Longer gets truncated on desktop and much sooner on mobile, usually mid-promise.
Match the words people searched
Google rewrites descriptions when it thinks a passage from the page fits the query better. One that already uses the searcher’s language survives far more often.
