Open Graph / Twitter Card Depth

1 OG/Twitter depth issue(s) detected

PASS

1 OG/Twitter depth issue(s) detected

1 Twitter Card field(s) differ from Open Graph counterparts

Twitter Cards inherit values from Open Graph tags when the Twitter-specific tag is absent (`twitter:title` falls back to `og:title`, etc.). Explicitly-set Twitter values that DIFFER from OG are usually stale -- the marketing team updates `og:title` for FB/LinkedIn previews and forgets to update `twitter:title` separately, leaving Twitter showing the old text. Mismatches: - title: twitter="costdown.org | Đề án Costdown", og="Costdown.org | Giảm Chi Phí Sản Xuất & K..." Fix: either remove the redundant Twitter-specific tags (rely on inheritance) or sync them when updating OG.

Got: 1 field(s) differ

Why this matters

Recommended schema properties unlock richer SERP layouts — without them you get the basic rich result instead of the enhanced one.

Recommended properties expand what Google can render. E.g., adding aggregateRating to Product unlocks star ratings; adding image to Article unlocks the image-card variant. Each recommended property is a direct SERP-real-estate gain.
