September 20th, 2015
The Photo, Gallery, and Product Cards were deprecated by Twitter on July 3rd, 2015. WPSSO continues to support all current Twitter Card formats, including the Summary, Summary with Large Image, App (exclusive to WPSSO), and Player Cards — in both the Free and Pro versions of WPSSO.
- Player Card — An embedded video in the Post / Page content.
- Large Image Summary Card — An image from the custom Social and Search Optimization, Featured, Attached, or NextGEN Gallery singlepic.
- App Card — Apple Store iPhone / iPad or Google Play App (requires the WPSSO Mobile App Meta extension).
- Summary Card — All other webpages.
For each type card you publish, you can submit a sample URL to Twitter's Card validation tool.
