What is Meta Description?

A meta description is a snippet of HTML (specifically the <meta name="description"> tag) that summarizes a page's content in 150-160 characters. While Google has stated that meta descriptions are not a direct ranking factor, they significantly impact click-through rates (CTR) from search results.

When a user searches for a query, Google displays the meta description (or a dynamically generated snippet) beneath the page title in search results. A compelling meta description acts as "ad copy" for your page, persuading searchers to click your result over competitors.

Best practices for writing effective meta descriptions include: keeping them under 155-160 characters to avoid truncation, including the primary keyword naturally (Google bolds matching terms), writing with an active, compelling voice, including a clear value proposition or call to action, and making each page's description unique.

It's worth noting that Google rewrites meta descriptions approximately 62% of the time, choosing to display a snippet from the page content that better matches the specific query. Despite this, writing good meta descriptions is still important because they serve as a default when Google doesn't rewrite, and they demonstrate intentional page-level optimization.

Meta descriptions directly influence click-through rates from search results. A well-written meta description can significantly increase your organic CTR, which drives more traffic without improving rankings. Higher CTR may also indirectly benefit rankings through user engagement signals. Plus, they're quick wins — improving meta descriptions is one of the fastest SEO optimizations you can make.
