Meta descriptions still drive clicks and now influence how AI assistants summarize your pages.
Generic, AI-fluff snippets lower CTR and make you invisible in AI Overviews.
In this guide you will learn proven meta description prompt patterns, guardrails, testing workflows, and multilingual variants so every description attracts people and AI systems.
Keep this aligned with our prompt engineering pillar at Prompt Engineering SEO to keep outputs consistent and compliant.
How to use this playbook
Pick a prompt pattern by intent and page type; swap placeholders.
Enforce guardrails: no fabrications, keep 140–155 characters, include primary intent and one proof.
Generate 3–5 options, then human-review for voice, accuracy, and compliance.
Log prompts and accepted outputs in your prompt library.
Test variants on top pages; monitor CTR, AI citations, and conversions.
Guardrails for safe prompts
Always include character limits (140–155 chars) and forbid fabricated numbers.
Require a clear benefit + entity mention; avoid clickbait or unsupported claims.
Specify tone and brand rules; forbid superlatives unless backed by proof.
For YMYL, include reviewer/credential mention if space allows and add caution wording.
Instruct model to avoid duplicating title text and to stay unique per page.
Add language and market to avoid wrong-language outputs.
Prompt building blocks
Role: “You are an SEO copywriter optimizing for CTR and AI citations.”
Inputs: keyword/intent, page type, audience, proof point, CTA, brand/entity, market/language, character limit.
Constraints: no fluff, no numbers unless provided, include entity, include benefit, stay within 155 chars.
Output format: numbered list of options with character counts.
Core prompt patterns by intent
Informational: “Write 5 meta descriptions (<=155 chars) for a guide on [topic] for [audience]. Include 1 benefit, 1 entity mention, and a clear outcome.”
How-to: “Create 5 action-led meta descriptions (<=150 chars) for a how-to on [task]. Mention the key step or tool and end with a direct CTA.”
Comparison: “Generate 5 comparison meta descriptions (<=150 chars) for [product] vs [competitor]. Include one differentiator and avoid hype.”
Transactional: “Write 5 meta descriptions (<=150 chars) for a [product/service] page. Include offer detail, trust cue, and direct CTA.”
Local: “Produce 5 local meta descriptions (<=145 chars) for [service] in [city]. Include service + city + one trust signal (reviews/years).”
Brand/authority: “Draft 5 meta descriptions (<=150 chars) that highlight [brand] expertise in [topic] with one credential or data point.”
Vertical-specific prompt sets

Multilingual patterns (swap language and locale)
EN: “Write 5 EN meta descriptions (<=150 chars) for [topic] in [country]. Include benefit + entity and keep native phrasing.”
PT: “Escreve 5 descrições (<=150 caracteres) em PT-PT para [tema] em [país]. Inclui benefício e entidade; sem exageros.”

DE: “Verfasse 5 Meta-Descriptions (<=150 Zeichen) auf DE für [Thema] in [Land]; Nutzen zuerst, keine leeren Versprechen.”
Local nuance: specify currency, measurement units, and local proof (reviews/regulators); keep glossaries for tone (vous/tu, PT-PT vs PT-BR).
Prompt patterns for existing pages (refresh)
“Given this current meta description: [paste], write 5 improved options (<=150 chars) that add a benefit and entity mention, remove fluff, and align to [keyword].”

“Write 5 meta descriptions (<=150 chars) that include the entity [Entity] and align with these
about/mentions: [list].”“Generate meta descriptions for [page] that echo this Person/Organization: [author/brand], include 1 credential, and stay under 150 chars.”
“For a page with FAQ schema on [topics], write 5 meta descriptions that summarize the top FAQ answer in <=150 chars.”
AI search and citation-focused prompts

“Use this stat [stat] and source [source] to lead the description; keep <=145 chars.”
“Add entity [entity] to prevent misattribution in AI answers; benefit first, <=145 chars.”
Programmatic and spreadsheet-friendly prompts
“For each row with columns [keyword, feature, proof, CTA], create a meta description (<=150 chars) combining them; output in a table with character count.”
“Given these product attributes [list], generate 3 meta descriptions (<=150 chars) per SKU with attribute + benefit + CTA; avoid duplicate phrasing.”
“Create template-style meta descriptions for category pages: format = [Category]: [2 key attributes] | [shipping note] | [CTA], under 150 chars.”
“Batch-generate local service meta descriptions using columns [service, city, proof, CTA]; return unique phrasing per city; <=145 chars.”
“Return a QA column flagging any description missing a benefit or entity, and any over 150 chars.”
Testing framework for meta description prompts
Select pages: top 50 by impressions/low CTR; group by template.
Variants: baseline + 2 prompt-generated options; keep titles constant.
Deploy: split URLs or time-based tests; ensure clean measurement windows.
Metrics: CTR, AI citations (if tracked), conversions, and snippet truncation.
Duration: 2–4 weeks depending on traffic; avoid peak season skew.
Analysis: pick winners per template; update prompt library with accepted outputs.
Segment by device and market; note mobile truncation risks.
For low-traffic pages, test at template level and monitor post-rollout impact.
QA checklist for outputs
Character count 140–155; no truncation risk on mobile.
Intent match: aligns with target query and search intent.
Entity and benefit present; no fabricated numbers.
Tone matches brand; no clickbait or compliance risks.
Unique per page; not a copy of title.
For YMYL: reviewer/credential mention if possible; neutral, factual tone.
Tool stack to support prompts
Prompt library/logs in Notion/Sheets with owners, versions, and outcomes.
Model playground with saved prompt templates; restrict access and rotate keys.
Snippet preview tools for mobile/desktop truncation by language.
Crawlers to check uniqueness and detect duplicate metas; parity checks for canonical vs variants.
Analytics and Search Console exports for CTR and impressions; AI citation logging scripts.
CMS checks: required fields, character counters, and block on duplicate descriptions.
Ops cadence
Weekly: generate/review metas for new pages; check for duplicates and truncation.
Biweekly: run micro-tests on top templates; log winners and losers.
Monthly: audit low-CTR pages; refresh metas; review AI citation logs for key queries.
Quarterly: retrain teams on guardrails; refresh prompts after SERP/AI changes; expand locales.
Common mistakes to avoid
Overstuffing keywords; weak readability and CTR drop.
Using the same description across many pages; creates duplicates and confuses AI answers.
Fabricated numbers or claims; risks trust and compliance.
Ignoring mobile truncation; hiding benefits on small screens.
Skipping entity mentions; AI misattributes answers to competitors.
Running tests without clean controls; misreading performance.
KPIs and diagnostics
CTR vs position; compare to template benchmarks.
Snippet truncation rate (mobile/desktop).
AI citations mentioning your page vs competitors for tracked queries.
Conversions and assisted conversions from pages with new metas.
Duplicate/empty meta count per crawl.
Review and edit rate: how many AI-generated metas need rewrites.
Time to ship: from prompt to approved meta; reduce with better guardrails.
Prompt library structure
Columns: use case/intent, vertical, language/market, prompt text, model version, guardrails, sample inputs, sample outputs, approver, date, performance notes, red-flag status.
Keep “best-of” prompts per template; archive weak performers with reasons.
Example meta description templates (plain text)
“[Primary benefit] for [audience] with [proof]. Learn how in [brand]’s guide.” (146 chars)
“[Product] with [attribute] + [shipping/returns cue]. Shop now at [brand].” (132 chars)
“[Service] in [city] with [response time/proof]. Contact [brand] today.” (125 chars)
“[Topic] explained by [credential]. Know when to call a pro. [Brand].” (144 chars)
Logging and governance
Store prompt, outputs, chosen version, approver, and date in a central log.
Tag by page type, market, and intent; note performance outcomes.
Red-flag prompts that caused hallucinations; block reuse until fixed.
Keep a glossary for brand terms, forbidden words, and compliance notes.
Track model/version and retest core prompts after updates.
Maintain a “best-of” tab with top-performing variants per template for quick reuse.
