Domain age in years, months, and days
Age benchmark. how it compares to typical authority thresholds
Registrar information. who manages the domain

Data via RDAP (Registration Data Access Protocol), the modern replacement for WHOIS, maintained by ICANN. Works for most .com, .com.au, .net, .org, and country domains.

DNS Propagation Map
When you update your DNS. pointing a domain to a new host, adding records, changing nameservers. the change takes time to spread across the global DNS network. This tool shows you which regions have picked up your changes and which are still serving the old records.
When to use this
After pointing a domain to a new host. check if it has propagated
After adding MX records for email. confirm globally visible
After adding SPF or DMARC. verify all regions have picked it up
After changing nameservers. track rollout progress globally
Troubleshooting. check if different users in different countries see different results
Checks 8 global DNS resolvers across Asia-Pacific, Americas, Europe, and the Middle East using Cloudflare DNS-over-HTTPS. Full propagation typically takes 15 minutes to 48 hours depending on your TTL setting.

Robots.txt Checker
Fetches your robots.txt file and explains in plain English what each rule means. which bots are allowed, what's blocked, and critically, whether AI crawlers like GPTBot, ClaudeBot, and Googlebot can access your site. If AI crawlers are blocked, you will never be cited in AI Overviews or AI-generated answers.
What this checks
Googlebot access. can Google crawl and index your site
GPTBot (ChatGPT): whether OpenAI can read your content
ClaudeBot (Anthropic): whether Anthropic can read your content
PerplexityBot. is Perplexity AI allowed to read your content
Blocked paths. which directories and pages are off-limits
Sitemap declaration. whether your sitemap URL is declared
Critical for AI visibility: Many sites accidentally block AI crawlers in their robots.txt. often by using a blanket rule that was added years ago. If GPTBot or ClaudeBot are blocked, no amount of schema or content optimisation will get you cited in AI-generated answers.

Tip: Run this on every page after setting up RankMath meta titles and descriptions. The Google preview shows you exactly what searchers and AI systems will see. before you submit to Search Console.
Free tool · Google PageSpeed Insights API
Page Speed Grader
Runs Google's PageSpeed Insights analysis on any URL and returns your Core Web Vitals scores. Page speed is a direct Google ranking factor and affects AI crawl efficiency. Slow pages get crawled less frequently and rank lower.
What this measures
Performance score. 0 to 100, Google's overall speed rating
LCP. Largest Contentful Paint, how fast the main content loads
FID / INP. Interaction to Next Paint, how responsive the page feels
CLS. Cumulative Layout Shift, whether elements jump around while loading
FCP. First Contentful Paint, when the first content appears
Mobile vs Desktop. separate scores for each device type
Powered by Google PageSpeed Insights API. This is the same data Google uses to evaluate page experience. Aim for 90+ on mobile. Under 50 is a ranking problem that needs fixing before anything else.
Free tool · No account needed
Sitemap Validator
Fetches your XML sitemap, checks it is well-formed, and verifies the URLs inside it are accessible. A broken or incomplete sitemap means Google and AI crawlers miss pages entirely, even if those pages are perfectly written and fully optimised.
What this validates
Sitemap exists and is accessible at the standard URL
XML is well-formed. no syntax errors that break parsing
URL count. how many pages are declared
Sitemap index. detects if it is a sitemap index pointing to child sitemaps
Sample URL check. verifies a sample of declared URLs are reachable
lastmod dates. checks modification dates are present and valid
Tip: After Rashmi submits your sitemap to Google Search Console, run this tool to confirm the sitemap is valid. Then check Search Console 48 hours later to confirm Google has started indexing the pages.
