Google confirmed years ago that meta descriptions are not a direct ranking factor. A lot of people heard that and stopped caring, which is precisely backwards. The description doesn't decide where you rank — it decides whether anyone clicks once you're there. Two sites in positions three and four can have wildly different traffic depending on which one wrote a better sixty-word pitch.
Google rewrites most of them anyway
Start here, because it reframes the whole exercise. Studies consistently find Google rewrites the majority of meta descriptions, pulling a passage from the page instead. This is not a failure — it usually happens because the searcher's query matched something in your body copy more specifically than your description did.
The practical implication: your description is a strong default for your main query, not a guarantee. Write it for your primary keyword, and make sure the rest of the page contains clear, quotable passages that answer adjacent questions well.
Length: think pixels, not characters
The common advice is 155–160 characters. What Google actually truncates on is pixel width, roughly 920px on desktop and less on mobile, so a description full of wide characters gets cut earlier than one full of narrow ones.
Practical rule: front-load the essential message in the first 120 characters. If the tail gets truncated, you've lost an elaboration rather than the point.
What separates good from forgettable
Answer the query, don't restate the title. The title already occupies the line above. A description that paraphrases it wastes the only space you control.
Be specific enough to be falsifiable. "Comprehensive guide to WordPress speed optimisation" is the kind of sentence anyone could write about anything. "The eight changes that move LCP, in the order worth doing them" tells the reader what they're getting.
Include the search phrase naturally. Google bolds terms matching the query, which measurably improves click-through. Force it in awkwardly and you lose more than you gain.
Give a reason to prefer you. Free, no signup, tested, updated for 2026, includes examples — one concrete differentiator beats three adjectives.
Before and after
Weak: "Learn about WordPress security in our complete guide. We cover everything you need to know about keeping your website safe and secure."
Better: "The 6 attacks that actually compromise WordPress sites — and the specific settings that stop each one. No plugin required for four of them."
The second is barely longer. It commits to a number, names the shape of the answer, and pre-empts the reader's "do I need to buy something?" objection.
Weak: "Buy premium WordPress plugins at great prices. Wide selection of quality plugins for your website needs."
Better: "Premium WordPress plugins with a 7-day refund, one licence per site, and updates included. Reviewed by hand before listing."
Again: specifics a competitor can't copy without matching the underlying policy.
Questions convert well
Opening with the exact question the searcher typed is one of the more reliable patterns, because it mirrors their intent back at them immediately. "Licence key showing invalid? It's almost always one of three things — here's how to tell which." That reads as a direct response rather than a brochure.
Doing this at scale in WordPress
Hand-writing descriptions for 400 posts is unrealistic. Prioritise: your top 20 pages by impressions in Search Console deserve individual attention, since that's where a CTR improvement produces meaningful traffic. For the long tail, a sensible template beats an empty field, and a tool that auto-fills every post — such as PlugPage SEO — is a reasonable floor to work up from.
Measure it honestly
Note the date you change a batch, then compare CTR for those pages 28 days before and after in Search Console, filtered by page. Watch for confounders: if average position moved at the same time, CTR will move with it regardless of your copy. A description change that lifts CTR by a percentage point on a page getting 10,000 impressions a month is worth more than most technical tweaks — and takes ten minutes.
