Questions & Answers

As answered by people managing ShareScan.io and Userscripts.

What makes your product unique?

ShareScan.io's answer

ShareScan continuously monitors your entire website for broken social previews, Open Graph issues, and metadata problems โ€” then alerts your team in Slack before those issues hurt clicks, campaigns, or trust. Unlike one-off preview checkers, ShareScan is built for ongoing monitoring across many pages, so problems donโ€™t go unnoticed after content changes, releases, or deployments.

Why should a person choose your product over its competitors?

ShareScan.io's answer

ShareScan is built for teams that want to move from manual checking to continuous monitoring. Instead of validating one URL at a time, ShareScan helps you keep track of preview issues across your website and notifies you when something breaks.

  • Monitors your whole site, not just a single page

  • Alerts you in Slack when issues are detected

  • Helps prevent lost clicks and broken campaigns

  • Useful for marketers, SEO teams, and developers

  • Makes social preview QA part of your workflow, not an afterthought

If link previews matter to your traffic, brand consistency, or campaign performance, ShareScan gives you a faster and more reliable way to catch issues early.

How would you describe the primary audience of your product?

ShareScan.io's answer

ShareScan.io is built for marketing teams, SEO specialists, content teams, and developers who manage websites where social sharing, metadata quality, and link preview consistency matter. It is especially useful for teams that publish frequently, run campaigns, or manage larger sites where preview issues can easily slip through unnoticed.

What's the story behind your product?

ShareScan.io's answer

ShareScan was created to solve a frustrating but easy-to-miss problem: pages can look perfectly fine on-site while still breaking when shared on social platforms, messaging apps, or collaboration tools. Missing Open Graph tags, broken images, stale metadata, and invalid cards can quietly hurt traffic, engagement, and trust.

We built ShareScan to help teams catch those issues before users do. Instead of relying on manual spot checks, ShareScan continuously monitors websites for preview problems and sends alerts when something breaks.

Which are the primary technologies used for building your product?

ShareScan.io's answer

ShareScan.io is built using modern web technologies for crawling, monitoring, analysis, and team notifications. The platform combines website scanning, metadata validation, backend processing, and Slack integrations to help teams detect and respond to broken preview issues quickly.

Who are some of the biggest customers of your product?

ShareScan.io's answer

We are not publicly listing customer names at this time.
