Write meta titles and descriptions that earn the click.
A meta description is the short summary that appears under your page title in search results. It is not a ranking factor, but it heavily influences whether people click, and Google rewrites it whenever it thinks its own snippet fits the query better.

Two things are true at once, and confusing them causes most of the bad advice on this topic. Google has said plainly that meta descriptions are not a ranking factor. Writing a better one will not move you up the results page.
But they strongly affect click-through rate, which is the entire point. Ranking third and getting clicked is better than ranking second and getting skipped. The description is your one piece of controllable ad copy in an otherwise fixed layout, and on commercial queries where every result looks similar, it is often the deciding factor.
The catch: Google rewrites meta descriptions a large share of the time, pulling a passage from your page instead. This is not a penalty. It happens when Google believes on-page text answers the specific query better than your generic summary. You cannot prevent it, but you can make it less likely, and you should still write one for every page, because when Google does use yours, you control the pitch.
Aim for 140 to 160 characters. Google truncates based on pixel width rather than a strict character count, and the cutoff is tighter on mobile than desktop, so treating roughly 155 characters as the ceiling keeps you safe on both.
Shorter is not a failure. A punchy 120-character description that says one clear thing often outperforms a 158-character one padded to hit the limit. The number is a boundary, not a target.
Put the important words early. If your description gets cut, you want the value and the search term to have already landed. Ending on an incomplete clause looks careless in a results page where everything else is tidy.
Match the intent behind the query, not just the keyword. Someone searching "how to write a meta description" wants instruction. Someone searching "meta description generator" wants a tool right now. The same page copy cannot serve both well.
Include the target term naturally. Google bolds words matching the query, which makes your result visually heavier in a page of grey text. That is a real, free advantage.
Be specific about what the reader gets. "Learn more about content marketing" promises nothing. "The five-step content workflow we use to publish daily with two people" promises something concrete and checkable.
Write a different one for every page. Duplicate descriptions across a site are a common technical issue and they guarantee Google rewrites most of them, because an identical summary cannot possibly be the best answer for many different queries.
The usual reason is a mismatch: your description is a broad summary of the page, but the searcher asked something narrow, and a specific paragraph inside your article answers it better. Google swaps in that paragraph. From a user's perspective that is the right call.
You reduce rewrites by making the description genuinely reflect the primary query the page targets, keeping it in the same language as the page, and avoiding filler like your company boilerplate. Pages that answer one clear question tend to keep their own descriptions.
