How do I control posts on Twitter, LinkedIn and Facebook?
When sharing an article or blog post (or any URL for that matter) on Facebook, Twitter or LinkedIn, these networks access Open Graph (og) metadata (title, featured image, short description) in order to produce a summary card.
If you change the title, image, or description and want to share it again on social media, you may be surprised to find that you're sharing the old content. This is because these media sites cache this content to avoid re-checking a URL every time it's shared.
Continuum generates the og metadata for each page but depends on there being a Teaser for each article or a Short Description for each Event or Directory Listing.
This cache can be cleared, and here's how to do it:
Go to the Facebook Debugger at https://developers.facebook.com/tools/debug/
Paste your URL into the text field and click Debug. This shows the result of processing the content of that URL. If you've already shared it, you will see the cached version, click Scrape Again to force Facebook to pull the most recent content.
Twitter has a card validator at https://cards-dev.twitter.com/validator
Simply enter the URL of the content you want to update and hit the Preview card button. The Log section at the end of the page displays the result of processing your content, so if there’s any problem with the Open Graph meta tags in your website, you’ll see it here. You can then repost your card.
LinkedIn has a post inspector at https://www.linkedin.com/post-inspector/
Simply enter the URL of the content you want to update and hit the Preview card button. The Log section at the end of the page displays the result of processing your content, so if there’s any problem with the Open Graph meta tags in your website, you’ll see it here. You can then repost your card.
It's important to note that by deleting the cache on social media, your previously shared posts will not change. This only impacts new posts.
