2 OG/Twitter depth issue(s) detected
Info::
og:image aspect ratio 1.00:1 (512×512) is outside Facebook's recommended ~1.91:1
Facebook's recommended OG image is 1200×630 (1.91:1 aspect ratio). The declared dimensions 512×512 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 (512×512)
Warning::
Twitter card is `summary_large_image` but OG image is 512×512 (ratio 1.00:1) -- closer to square
`twitter:card` is set to `summary_large_image` (the wide-image preview format), but the declared OG image dimensions (512×512, aspect ratio 1.00:1) are closer to square than wide. Twitter will crop the image to fit the wide format, often badly. Either: (1) provide a wider image (~2:1 ratio recommended; minimum 600×314, optimal 1200×630), or (2) change `twitter:card` to `summary` which uses a square thumbnail crop.
Got: 512×512 declared with summary_large_image card

JSON parse error: json: cannot unmarshal array into Go value of type map[string]interface {}

Why this matters

JSON-LD block fails to parse — Google ignores the entire block, so structured data effectively isn't there.

Info::
2 below-fold images missing loading="lazy"
Lazy loading defers below-fold images, reducing initial page weight.
Info::
1 image(s) rendered at a different aspect ratio than the source
The displayed dimensions distort the source -- CSS is forcing the image into a container at the wrong ratio, producing visible stretching or squashing. Either crop the source to match or use object-fit: cover (and accept the crop). Sample: https://daelim-electric.com/wp-content/uploads/2021/07/logo.webp.
