Cards with multiple Content Attributes


I want to make a card that will show up for many unique URLs on my website, without having to create an original card for each page (blog posts). I’ve attempted to just list each URL as an attribute but when I do it appears that every other URL attribute is cancelled out, meaning that only half of the URLs work in making a card when tweeted. I don’t know enough HTML currently to understand why it’s doing this. Does anybody have any ideas on how I can have a large number of urls show the same generic card, without having to create cards for each unique URL?
