I have a wordpress.COM blogging site and on their support page it mentions Twitter cards. When i manually type in the meta data to the html view of a blog post and then put that link into the Card Validadtor it seems to be approved as you said.
When i close my blog and go back to the same post i’ve noticed that the meta data has disappeared from the blog post html view.Here is the link to the post containing the meta data.
I just posted it on twitter but the summary card did’nt appear (apart from when i select ‘view summary’. Here is the tweet link: https://twitter.com/adsdiaspora/status/573245584271933440
according to wordpress.com: “Twitter requires you to first validate your site to use Twitter Cards in order to share images through Publicize. You do this by submitting a post to their Card Validator. This will need to be done for each Card Type by submitting a post example for each. For example if your post has a gallery, Twitter will share it as a Gallery Card, this Card Type would need to be validated.”
Thanks for your help!
