LinkFork lets you shorten a URL and customize how your link will appear when shared on social media — for free.
With LinkFork you can easily find out which version of your shared link preview works the best.
How does the preview customization work?
We use Open Graph meta tags, which are snippets of code that control how URLs are displayed when shared on social media. They’re part of Facebook’s Open Graph protocol and are also used by other social media sites, including LinkedIn and Twitter (in case Twitter Cards are absent).
