Kindergarten enrollment runs by word of mouth on group chats. A parent finds the program page, sends the link in a class WhatsApp, and ten other families see the preview in a thread. If the preview is the WordPress default avatar and a stretched logo, the link goes uninvestigated. If the preview shows the school name, the program track, and the next tour date, three families RSVP.

The page content already lives on the site. Most kindergartens run pages for each program (half-day, full-day, mixed-age, parent-toddler) and posts for tours, holiday calendars, and policy updates. Every OG image needs is already typed once on the page. What gets done manually, if at all, is one generic image in a Featured Image field that has been there since 2021.

The fix is to render the OG image the same moment the page saves. Update the half-day program description, the 1200x630 PNG regenerates with the new title and tour date. The Featured Image, the og:image meta tag, and the Twitter card stay in sync without anyone opening a design tool.

Kindergarten waitlists fill by referral. A parent at a tour mentions the school to two other parents at pickup, those parents share the link in a group chat, and the link preview is what decides whether the next ten people on the thread click. The page itself can be beautiful, but if the WhatsApp preview is a stretched homepage logo on a beige square, the link gets scrolled past.

Most kindergartens do not have a marketer on staff. They have a head teacher who runs admissions, a director who handles community outreach, and a board that meets twice a term. That setup works for a printed enrollment packet, but it breaks on the social layer where every share is a first impression.

Treating the OG image as derived from the page content means the social preview matches the printed packet, and every share looks like the kindergarten parents toured last week.
