I am not sure if anyone is familiar with implementing Twitter Cards (https://dev.twitter.com/docs/cards) into a blog, but if anyone is I could use some help. It seems like it should be working on my blog, but my posts don't work in Twitter's testing tool () if I provide the url. However, if I copy and paste the twitter card meta tags in instead, they display fine. I can't figure it out for the life of me.

Here is an example URL:

Here is example Twitter Card info:

<!-- Twitter Cards (in beta!) -->
<meta name="twitter:card" content="summary" />
<meta name="twitter:url" content="" />
<meta name="twitter:title" content="#BingItOn! Data Says Google Wins The Bing Search Challenge" />
<meta name="twitter:description" content="Bing has challenged Google, claiming people prefer Bing 2 to 1 according to a blind study, but my data says otherwise. Check out my analysis!" />
<meta name="twitter:image" content="http://1.gravatar.com/avatar/5eb28ff44dd0814a7cd5808eec8d3598?size=120" />
<meta name="twitter:site" content="@fighto" />
<meta name="twitter:creator" content="@fighto" />

Any assistance would be appreicated :)

Short answer: most problems come from the card meta not being present in the final server-rendered HEAD, the Twitter crawler being blocked or unable to fetch images, or from Twitter caching an older version of the page. Historically found the approval step confusing — player/player-like cards still require extra validation — but the usual checklist below will fix 9/10 issues. (developer.x.com)

Do this first (fast smoke tests): view-source in your browser or fetch the raw HTML from the server and confirm the twitter: meta tags appear in the HEAD (if your CMS injects tags via JavaScript they won’t be seen). Emulate the crawler to see what it gets:

# fetch raw HTML and look for twitter meta tags
curl -L -s 'https://your-site.example/your-post' | grep -i 'twitter:'

# emulate Twitter's crawler user-agent to check server response
curl -I -A "Twitterbot/1.0" 'https://your-site.example/your-post'

Also confirm the page returns HTTP 200, has a normal Content-Type, and that robots.txt or host firewall isn’t blocking Twitterbot. (developer.x.com)

If tags look correct but cards still fail, use the Card Validator to re-scrape and read the exact error. Twitter caches card data (roughly seven days after a URL is published); the validator shows timeouts, image problems, or size errors and suggests fixes. If images aren’t updating, give them a cache-busting query string (or use unique short URLs for testing). (developer.x.com)

Notes on special cases: Player (and some App) Cards have stricter rules (HTTPS, playable in a browser iframe, specified width/height, image pixel requirements) and are subject to additional validation/approval. If everything checks out but the validator still fails, verify crawler IPs/reverse-DNS, check server logs for requests from Twitterbot, then post the validator output in the developer forums for help. Mentioning and here matches the thread’s timeline — the dev docs linked above are the up-to-date reference for these items. (developer.x.com)
