What Google does with your description
The snippet under a result comes mainly from the page content. Google uses your meta description when it describes the page better for that search. So one page can show different snippets for different searches. Google also cuts long snippets to fit the screen, and it publishes no fixed length.
Google stated years ago that it does not use the description tag for ranking. Its value is the click.
What a good description includes
- What the page offers, in the words customers use
- Where you serve, when the search is local
- One specific reason to choose you
- A plain next step, such as call or book
Good example. "Same-day emergency dental care in Orlando. We see walk-ins before noon and accept most PPO plans. Call to book a visit today."
Bad example. "Dentist Orlando, best dentist, dental services, cosmetic dentist, dentist near me." Google is unlikely to show it, and searchers learn nothing.
Write unique descriptions for pages that matter
Google's guidance warns that identical descriptions across a site do not help. If time is short, write them for your homepage and service pages first. Large sites can generate them from page data, as long as they read naturally and differ from page to page.
Measure the effect
Descriptions change clicks, not positions. In Search Console, compare the click-through rate of a page before and after a rewrite. Allow a few weeks, since Google has to recrawl the page first.
Pair each description with a strong title tag. If your CMS makes them hard to edit, our web design team builds sites where every page has its own editable title and description.
