1 OG/Twitter depth issue(s) detected
PASS
1 OG/Twitter depth issue(s) detected
Info::
og:image aspect ratio 1.00:1 (600×600) is outside Facebook's recommended ~1.91:1
Facebook's recommended OG image is 1200×630 (1.91:1 aspect ratio). The declared dimensions 600×600 give a ratio of 1.00:1, which Facebook will crop center-to-fit; the result often clips important content from the top/bottom or sides. Use a wider/taller image close to 1.91:1, or accept the cropping consequences.
Got: 1.00:1 (600×600)
