Why we picked it Paste your landing page URL and it shows you exactly how the link renders when someone drops it into WhatsApp, Slack, LinkedIn, X, or Telegram, which is where a lot of early founder traffic actually starts. It is free, needs no login, and flags the missing og:image or og:title that make your link show up as a blank grey box. This is the one pre-launch SEO chore that pays off immediately, before Google has even indexed you.

- A blank or broken share preview quietly kills click-through on every link you paste into chats and DMs, so fix og:image and og:title first.
- It previews across WhatsApp, Slack, Telegram, LinkedIn, and X in one go, matching how founders in India actually share links.
- No login and unlimited checks, so you can re-test every time you change the page copy or hero image.
