Open Graph tags are specialized HTML meta tags originally created by Facebook in 2010. They standardize how URLs are displayed when shared across social networks and messaging apps. Today, almost every major platform, including LinkedIn, Slack, Discord, and iMessage, uses Open Graph tags to generate rich link previews with titles, descriptions, and images.
The universally recommended image size for Open Graph and Twitter cards is 1200 x 630 pixels (an aspect ratio of 1.91:1). This ensures your image looks crisp on high-resolution displays and renders perfectly across Facebook, Twitter, LinkedIn, and other major platforms without being awkwardly cropped.
Yes. While Twitter (now X) will gracefully fall back to reading your Open Graph (og:) tags if specific Twitter tags are missing, they still require the <meta name="twitter:card" content="summary_large_image"> tag to guarantee your link is displayed as a large, eye-catching image card rather than a small thumbnail.
If you want your website to function as a Progressive Web App (PWA) when saved to a user's home screen, yes. The <link rel="manifest" href="..."> file tells Android devices how to install your app, while <link rel="apple-touch-startup-image" href="..."> tags provide the loading screens for iOS devices. You can generate these using our free PWA Manifest Generator and iOS Splash Screen Generator or with the full version of Progressier.
Social networks heavily cache metadata to speed up their platforms. If you update your image or title, platforms like Facebook, LinkedIn, and X will still show the old version for several days. To fix this instantly, you must force them to scrape your new tags using their official developer tools, such as the Facebook Sharing Debugger or the LinkedIn Post Inspector.
Messaging apps are much stricter about Open Graph images than standard social networks. Your image is likely failing for one of two reasons: either the image URL in your og:image tag is a relative path (e.g., /images/og.png) instead of a fully qualified absolute URL (e.g., https://yoursite.com/images/og.png), or the file size is simply too large (iMessage and Discord often silently fail to load images over 1MB or 2MB).
Standard HTML meta tags (like descriptions and Twitter tags) strictly use the name="" attribute. However, Open Graph tags were built on top of a framework called RDFa, which requires the use of the property="" attribute. While most modern scrapers are forgiving and will figure it out if you mix them up, strictly adhering to name for standard/Twitter tags and property for Open Graph tags ensures total cross-platform compatibility.
A favicon (short for "favorite icon") is the small logo that appears next to your website's name in browser tabs. While historically it was just a branding element, search engines like Google and Bing now explicitly display your favicon directly in their mobile and desktop search results. Missing a valid favicon can reduce your click-through rate (CTR) as it makes your search snippet look incomplete or untrustworthy compared to competitors.
Many older meta tags are no longer supported by modern browsers and only add bloat to your HTML. For example, Windows 8/10 tile tags like msapplication-navbutton-color or msapplication-TileColor are obsolete. Similarly, basic <meta name="keywords"> tags have been ignored by Google for over a decade. Keep your <head> clean by focusing only on modern Open Graph, Twitter, and standard SEO title/description tags.
