Google SERP preview
Google truncates by pixel width, not character count — roughly 580px for titles and 920px for descriptions. This measures the real thing.
Open Graph & Twitter tags
How your link looks when it's pasted into WhatsApp, LinkedIn or Slack — plus the tags to paste into your <head>.
Schema.org JSON-LD
Structured data Google actually uses for rich results. Paste the output into a <script type="application/ld+json"> tag.
QR code generator
No watermark, no expiry, no tracking redirect — the QR encodes your URL directly, so it can never be switched off by a third party.
UTM campaign builder
Consistent tagging is the difference between usable analytics and guesswork. Values are lower-cased automatically.
robots.txt builder
Including the AI crawlers, which most generators still ignore.
Sitemap checker
Paste your sitemap XML. Browsers can't fetch another domain directly, so this validates what you paste rather than crawling for you.
Keyword density
Most-used words and two-word phrases, with stop-words removed. Above about 3% on any single term starts to read as stuffing.
GST calculator
Indian GST, both directions — add tax to a base price, or pull the tax back out of an inclusive one.
