I once launched a major article whose Twitter card showed a cropped logo and the text ‘Untitled Document’, because nobody had previewed the meta tags. It earned thousands of impressions looking broken. Social cards are first impressions at scale, and they’re generated by tags most authors never look at.
Paste your URL or meta tags to preview exactly how the page renders as a Google result, Twitter/X card, and Facebook/Open Graph share. Check the title length (truncation kills click-through), description, image presence and crop, and the og:image dimensions platforms actually want (1200×630 for Facebook/LinkedIn, 1200×675 for Twitter large cards).

Publishing discipline that prevents repeats: every post gets a unique title under 60 characters, a description under 160 that sells the click, and a dedicated social image (never let platforms auto-grab a random content image). After fixing tags on live pages, re-scrape via each platform’s validator, cached cards persist for days otherwise, and ‘but I fixed it’ means nothing until the cache refreshes.
Bottom line: preview every page, size images per platform, re-scrape after fixes.
