Free Online SEO and Crawler Tools

Validating robots.txt ensures search engine index bots (like Googlebot, Bingbot, and DuckDuckBot) can discover and crawl your pages without encountering syntax errors, conflicting Disallow directives, or accidental indexation blocks. Our free online seo and crawler tools validate sitemap XML schemas and directives 100% client-side without exposing staging environments.

No. All Telekit free online seo and crawler tools execute 100% locally inside your browser memory sandbox. No requests, URLs, or telemetry are sent to search engines or external analytics servers, ensuring your staging URLs and draft campaigns remain strictly confidential.

Google typically truncates desktop search snippet titles at ~600 pixels (approx. 55–60 characters) and mobile titles at ~680 pixels. Meta descriptions are typically truncated at ~960 pixels (approx. 155–160 characters on desktop and ~120 characters on mobile). Our Meta Tag Preview tool simulates character counts and pixel widths in real time.

For OpenGraph (Facebook, LinkedIn, Discord, Slack), the recommended image resolution is 1200 × 630 pixels (1.91:1 aspect ratio) with a file size under 8MB. For Twitter Cards, summary_large_image requires a 1200 × 600 or 1200 × 630 pixel graphic (2:1 or 1.91:1 aspect ratio), whereas standard summary cards display a square 1:1 image (minimum 144 × 144 pixels).

AI crawler bots respect standard User-agent rules in robots.txt. You can disallow specific AI scraper bots (e.g., User-agent: GPTBot / Disallow: / or User-agent: ClaudeBot / Disallow: /) while keeping standard search engine crawlers (User-agent: Googlebot) allowed to index your content, or validate full crawl permission matrices locally.

Standard XML sitemaps must adhere to the http://www.sitemaps.org/schemas/sitemap/0.9 schema namespace and are capped at 50,000 URLs or 50MB uncompressed per file. Larger websites use sitemap index files (<sitemapindex>) to group multiple child sitemaps. Our validator checks schema namespaces, <loc> URL formatting, and <lastmod> ISO date formats.

The URL Metadata Extractor inspects <script type="application/ld+json"> blocks, validating Schema.org types (e.g. Article, Organization, Product, FAQPage, BreadcrumbList, WebSite). It extracts all top-level properties, checks required fields, and provides 1-click JSON report exports.

Major platforms cache OpenGraph image and title metadata on their edge CDNs for several days. If you update meta tags, you can re-validate with Telekit tools to verify HTML tags, and then trigger cache purges on platform debuggers (such as Facebook Sharing Debugger or LinkedIn Post Inspector).
