أداة: Meta tags checker
ما الذي يقدمه هذا القسم
Give a public page URL and the tool fetches the HTML head enough to list critical tags: <title>, description and robots directives, canonical hints where present, plus common Open Graph and Twitter fields used when links unfurl in Slack, iMessage, or search results. You get a sanity snapshot—character counts, duplicates, missing descriptions—not a full Lighthouse audit. Pair it with your CMS preview when copywriters insist "the metadata saved" but SERPs still show legacy text from cache.
متى تستخدمها
Use it before launch checklists, after A/B testing landing templates, or when social shares show the wrong hero image. Combine with أداة: HTTP headers lookup for X-Robots-Tag and caching signals that live outside <meta>, and أداة: Google cache checker when the live tag looks right but Google still displays an older snippet. For markup slimming, follow up with أداة: HTML minifier or أداة: HTML tags remover in staging—not blindly on production without tests.
مثال عملي
Product announces a pricing change. The meta tags checker shows og:image still pointing at last quarter's PNG while twitter:image updated. Social posts continue pulling stale creative until you align both tags, invalidate CDN paths, and re-scrape via each platform's debugger. Document the before/after screenshots for the release notes.
أسئلة شائعة
Why does my tag show twice?
Plugins, tag managers, and theme partials often emit duplicates. Search engines pick a winner heuristically—clean duplicates to avoid ambiguity.
Does this validate structured data?
This page focuses on classic meta and social tags. JSON-LD structured data needs schema-specific validators.
Why can't I scan my localhost?
The checker must reach your URL from its environment. Use tunnels or staging hosts exposed to the internet for remote audits.
Is title length a hard rule?
Pixel width matters more than raw characters. Treat guidelines as UX targets, not magic numbers.
