Meta Descriptions Write the Copy That Earns the Click

What the meta description actually does

The meta description is an HTML tag in the page head that supplies the summary text search engines may show under the title in results. Google does not use its wording as a ranking factor, but it frequently overrides poorly written or missing descriptions with a snippet pulled from body text that may not match the searcher's intent.

A well-written description acts as a micro advert: it should promise the specific outcome the page delivers and distinguish it from the nine other results on the page, because higher click-through rate is a strong secondary signal that correlates with sustained or improved rankings over time.

Length and formatting rules

Keep descriptions to roughly 150-160 characters; Google typically truncates around 920 pixels on desktop, which is a little more forgiving on mobile. Write in active voice and address the reader directly with 'you' or an imperative verb, and where relevant include the exact query phrase, since Google bolds matching terms in the snippet, which draws the eye.

Avoid wrapping the description in quotation marks or special characters that can break rendering, and never duplicate the description word-for-word across multiple pages, which wastes the opportunity to differentiate similar pages.

Writing descriptions that convert

Include a concrete detail a competitor's snippet is unlikely to have: a number, a timeframe, a named feature or a specific outcome. For commercial pages, add a soft call to action such as 'compare plans' or 'see pricing'; for informational pages, state what the reader will learn or be able to do after reading.

• Target 150-160 characters, test in a SERP preview tool
• Include the target keyword naturally once
• Add one differentiating, concrete detail
• End commercial pages with a soft call to action

Auditing descriptions in RankAudit

RankAudit's Meta Descriptions report lists pages with missing, duplicate or over-length descriptions and shows the estimated pixel width for each. Prioritise your highest-traffic landing pages first, since a click-through rate improvement there has the biggest volume impact, then work down through the rest of the crawl.

After editing, use the report's re-check function to confirm the new description is under the truncation threshold before you move to the next batch of pages.

Key takeaways

• ✓Treat the description as ad copy, not a ranking lever
• ✓Keep it to 150-160 characters and avoid duplicates
• ✓Include one concrete, differentiating detail
• ✓Fix highest-traffic pages first using RankAudit's report
