The lengths that matter
Google shows roughly 60 characters of a title and 160 of a description before truncating — the counters turn red past those marks. Front-load the words people search for, and treat the description as ad copy: it does not affect ranking directly, but it decides whether people click your result or the one below it.
One image, every platform
The Open Graph tags drive the link cards on Facebook, LinkedIn, WhatsApp, Slack and Discord; the Twitter tags cover X. One 1200×630 image satisfies all of them — keep any text inside the middle 80% since some platforms crop the edges. The generated block includes explicit width and height tags so the first share renders with the image instead of after a re-scrape.
Frequently asked questions
Where do these tags go?
Inside <head>, as early as practical. Social crawlers read the raw HTML — tags injected later by JavaScript are often missed, which is the usual reason a share card shows no image.
Does anything get uploaded?
No. The tags are assembled in the page; nothing about your site is sent anywhere.
