Overview
SEO & Website tools on SmarTool Palace are grouped around one purpose: helping users inspect website metadata, links, headers, and crawler hints. The category includes Meta Tag Analyzer, Google & Open Graph Preview, Robots.txt Generator, Sitemap Validator, HTTP Headers Checker, UTM Builder, and additional focused utilities, with each page pairing the working tool with practical notes about inputs, checks, and limitations.
Choose the utility that matches the final output you need first, then check whether the page asks for a file, value, URL, date, location, or live lookup. If a task affects money, health, legal deadlines, publishing quality, or official documents, use the result as a reviewed estimate and confirm it with the relevant professional, authority, or source.
Website checks reflect the response available at the time of the request. CDN, redirects, personalization, and crawler-specific responses can produce different results.
Best uses and checks
- Preview a title and meta description before publishing.
- Check a redirect chain after migration.
- Validate robots.txt or sitemap syntax.
Common mistakes
- Testing a staging URL that blocks crawlers.
- Assuming one fetch matches every search-engine crawler.
- Publishing schema without validating required properties.
