What a meta description is actually for
It is not a ranking factor. Google confirmed that years ago and has repeated it since — you can write a perfect description and it will not move you a single position.
What it does is win the click. Your result sits among nine others, and two lines of text are most of what distinguishes them. A description that says what the reader gets, concretely, takes clicks from results that say "We provide the best solutions for all your needs".
Those clicks matter for reasons beyond the traffic itself: they are the difference between ranking third and getting nothing, and ranking third and getting a third of the page's visits.
