Over the past week I've been doing free technical audits for sites posted in feedback subreddits (r/websitefeedback, r/reviewmyshopify and similar) - measuring each one with curl, Chrome DevTools and raw HTML reads before commenting. Eight audits in, the same handful of problems keeps showing up, and they're mostly NOT the things speed tools yell about. Here they are, with real numbers.
1. Your share preview is your storefront window - and it's often empty
A merch brand about to promote its store to an engaged social audience had no og:image, no twitter:image, and no meta description. Every link shared to Instagram Stories, X, Discord or iMessage unfurled as a text-only card with a blank thumbnail - for a brand whose entire pitch is aesthetics. Same store's homepage title tag was the bare domain (the platform fallback when the SEO title is unset).
The fix is minutes: one strong social sharing image + a homepage meta description, set before the promo push, not after. If you check nothing else before launch, check what your link looks like when pasted into a chat.
2. Entrance animations hide your page from the people you're trying to impress
