Meta Description Guide
Why meta descriptions are still worth writing
Google doesn't use meta descriptions as a ranking factor — they use them as a click-through factor. A good description is your page's elevator pitch in the SERP. A great one pulls 20–30% more clicks than whatever Google auto-generates.
Pixel, not character
Google truncates at ~920px on desktop. That's roughly 155–160 characters of average English text — but the exact number depends on which letters you use. We measure the actual rendered pixels.
Two-line rule
Desktop meta descriptions render across two lines. If your copy lives above the fold and has clear call-to-action in the first 120 characters, truncation matters less — the important part is already read.
Write like ad copy
The meta description is one of the few places on your site where you should write like a marketer, not a technical writer. Lead with the benefit, include a soft CTA, and make the reader curious.
Include the keyword
Google bolds matches between the user's query and your description — bolded words catch the eye and drive clicks. Include the target keyword naturally, preferably in the first half.
Mobile is tighter
Mobile SERPs cut descriptions around 680px — meaningfully shorter than desktop. If mobile dominates your traffic, target 680px or less for consistent rendering across devices.
Don't copy the first paragraph
Many CMSes auto-fill the meta description with the first 160 characters of body copy. This usually produces a weak SERP snippet — write a purpose-built description and save the first paragraph for real content.
Pro Tips
Close with a soft call to action: 'Learn more.' 'Free tutorial.' 'No signup.' These don't add many pixels but meaningfully increase clicks.
Digits and dates can eat pixel budget. '2026 edition' costs more pixels than you'd guess. Leave them off unless freshness is the primary selling point.
Paste the description here (desktop), then shorten to 680px and test in our SERP Preview tool for mobile. A single description that works well on both is the goal.
Frequently Asked Questions
- Is Google rewriting my meta description?
- Often, yes — Google rewrites up to 70% of descriptions when they think yours doesn't match the specific query. A well-crafted, keyword-matched description is more likely to survive rewriting.
- What about Open Graph descriptions?
- Different field, different purpose. Meta description is for search; og:description is for social shares. Our Open Graph Generator builds those separately — use both.
- How often should I update meta descriptions?
- Review descriptions quarterly. If a page's CTR is lagging behind its ranking (e.g., #3 but low CTR), test a new description. Google re-indexes meta tags fast — changes show up in SERPs within days.
- Can descriptions be over 160 characters?
- Technically yes, and Google occasionally shows longer snippets. But plan for ~155–160 character visibility — anything beyond risks truncation on every rendering, and you never know which part will be cut.
