OpenGraph is a protocol that enables any web page to become a rich object in a social graph. It was created by Facebook in 2010 to standardize how web pages are represented when shared on social media platforms. OpenGraph uses HTML meta tags (og:title, og:description, og:image, etc.) to provide structured metadata about a webpage, allowing social platforms to display rich previews with images, titles, and descriptions when links are shared.
OpenGraph was invented by Facebook (now Meta) in 2010. The protocol was introduced as part of Facebook's Open Graph API, designed to help websites integrate with Facebook's social platform. The specification was later adopted by other major social media platforms including Twitter (which created Twitter Cards as an extension), LinkedIn, and many others, making it the de facto standard for social media link previews.
Checking OpenGraph tags is essential for several reasons:
OpenGraph is the original protocol created by Facebook, while Twitter Cards are Twitter's extension of OpenGraph. Twitter Cards use similar meta tags (twitter:title, twitter:description, twitter:image) but may have different size requirements for images. Most modern websites implement both to ensure optimal display across all platforms.
Facebook and LinkedIn recommend 1200x630 pixels for optimal display. Twitter Cards support multiple sizes, with 1200x675 pixels being ideal for summary cards with large images. Images should be at least 600x315 pixels to avoid being rejected by social platforms.
OpenGraph tags don't directly impact search engine rankings, but they significantly affect social sharing and engagement. Higher social engagement can lead to more backlinks and traffic, which indirectly benefits SEO. Additionally, some search engines may use OpenGraph data in their search results.
Without OpenGraph tags, social platforms will attempt to extract information from your page's HTML (title tag, meta description, first image), but results are often suboptimal. You may get generic previews, incorrect images, or truncated descriptions that don't represent your content well.
Yes, you can use the same image, but it's recommended to optimize it for both platforms. Twitter Cards may crop images differently, so ensure important visual elements are centered. Many websites use the same og:image for both, which works well in most cases.
