Server responses and client rendering should be examined separately when diagnosing missing content.\nDoes a passing checker guarantee search rankings?\nNo. A technical check answers a bounded question, such as whether a tag is present or a URL responds. It does not measure every aspect of usefulness, relevance or search quality.\nContinue your workflow:\nSchema generator\n,\nHreflang generator\n.",

Correct invalid input before retrying; retry server-busy responses with bounded backoff. Returned files contain Base64 data, not persistent download URLs. Decode and inspect the output before treating conversion as successful. See the shared API guide for the complete status and timeout rules.\n\n### Browser-agent workflow\n\n1. Open the human page in a browser that supports WebMCP.\n2. Discover the interface exposed by that page; use its actual schema.\n3. Select files on the page first when the tool requires files.\n4. Call `run_current_tool` with valid input and settings.\n5. Inspect the returned result or error and the displayed output. Retrieve files from the displayed download links.\n\nCalls do not automatically copy or download results. Browser permissions still apply. Interface availability alone is not proof of successful execution.\n\n### Planning specification\n\nEscaped title, description, robots and social metadata; live snippet is approximate.\n\nThis describes intended requirements. Use the implementation notes, interface schema and observed output to determine current support.\n\n### Complete machine-readable capability record\n\n```json\n{\n  \"id\": \"meta-tag-generator\",\n  \"category\": \"web-tools\",\n  \"built\": true,\n  \"requirements\": \"Escaped title, description, robots and social metadata; live snippet is approximate.\",\n  \"implementation\": {\n    \"fields\": [\n      {\n        \"key\": \"title\",\n        \"label\": \"Page title\",\n        \"value\": \"\",\n        \"type\": \"text\"\n      },\n      {\n        \"key\": \"description\",\n        \"label\": \"Description\",\n        \"value\": \"\",\n        \"type\": \"text\"\n      },\n      {\n        \"key\": \"index\",\n        \"label\": \"Allow indexing\",\n        \"value\": true,\n        \"type\": \"checkbox\"\n      }\n    ],\n    \"experience\": {\n      \"automatic\": false,\n      \"single\": false,\n      \"label\": \"Your text\",\n      \"placeholder\": \"Type or paste your input…\",\n      \"help\": \"Up to 1,000,000 characters.

Review the settings, then choose Run Meta tag generator.\n3. Review the result, then use Copy result or a download link when available.\n\n## Working with meta tag generator\n\nWebsite checks examine different layers: the HTTP response, page source and rendered document may not be identical. Decide whether you need to inspect a URL, validate supplied markup or preview how a browser renders a page.\n\n## Common questions\n\n### Why can a browser page differ from its source?\n\nJavaScript can add or modify content after the initial HTML arrives. Server responses and client rendering should be examined separately when diagnosing missing content.\n\n### Does a passing checker guarantee search rankings?\n\nNo. A technical check answers a bounded question, such as whether a tag is present or a URL responds. It does not measure every aspect of usefulness, relevance or search quality.\n\nContinue your workflow: [Schema generator](https://happytails.ai/en/web-tools/schema-generator/), [Hreflang generator](https://happytails.ai/en/web-tools/hreflang-generator/).\n"
