Questions fréquentes

Why 60 and 160 characters?

Google truncates most titles around 60 characters and descriptions around 160 in desktop search results. The counter warns above those limits.

Do I need both OG and Twitter tags?

Twitter falls back to OG tags, so a minimal setup can skip the twitter:* duplicates. Including both gives explicit control on X.

Should my OG image be PNG or JPG?

Either. 1200×630 is the standard. Avoid SVG - many social platforms reject it.
