FAQ
How does the AI Meta Tag Builder work?
Enter your page title, description, URL, image, type, and robots directive. The engine renders valid HTML meta tags for title, description, canonical, robots, Open Graph, and Twitter Card, plus a JSON-LD stub (Article / Product / Website / Breadcrumb). Live previews show how your snippet will look on Google SERP, Facebook, X (Twitter), LinkedIn, Slack, and Discord. Pixel-width and character meters warn you when titles or descriptions exceed typical platform limits.
What are the pixel-width and character limits?
Google SERP title: 600px (≈ 50–60 chars). Google SERP description: 920px (≈ 150–160 chars). Open Graph title: 60 chars (no strict pixel limit). Twitter title: 70 chars. Twitter description: 200 chars. The tool shows red/amber/green indicators per platform so you can resize before publishing.
Can the AI draft titles and descriptions from my page content?
Yes. Paste your page text and click 'Draft from content' — the on-device engine extracts the top keywords and generates a title candidate and description candidate using the first sentences of the content. For higher-quality drafts, paste your own LLM API key (OpenAI or Anthropic) and click 'Enhance with LLM' — that request goes directly from your browser to the LLM provider.

Is my data sent anywhere?
No. All tag generation, preview rendering, and pixel-width calculation run locally in your browser. The page text never leaves this device. The only network call is if you paste your own LLM API key and click 'Enhance with LLM' — that request goes directly from your browser to the LLM provider you choose.
