Metaspry vs. doing it yourself
Manual means View Source, scattered free validators, and a spreadsheet to track it - with no history and no alerts. Metaspry puts it in one place: scored, saved, bulk, monitored, shareable.

When you'd reach for it
Before publishing
Catch a missing og:image, a truncated description, or a stale canonical before the post goes live.
Auditing client sites
Run a one-pass audit, export the JSON, hand it to the client with a concrete fix list.
Sharing previews
Pull up the social and search renderings side-by-side and screenshot the one that breaks.
Keeping watch in production
Pin your key URLs in the cloud app and get alerted the day a redeploy drops an og:image or ships a stray noindex - before a customer notices.
Auditing at scale with a team
Bulk-audit hundreds of URLs from a sitemap, track fixes on a shared board, and give the whole team one workspace with roles.
