Using Gatsby and Puppeteer to create dynamic Open Graph images

Open Graph images, which appear when links are shared on social media platforms, serve as a valuable opportunity for free advertising, yet many companies underutilize this space by displaying only their logos or branding. In a bid to capitalize on this opportunity, PostHog revamped its approach by creating custom Open Graph images tailored for individual web pages, dynamically generating images to reflect current content. This initiative, inspired by GitHub's recent improvements to their link previews, aims to enhance the visual appeal and context of shared links, thereby increasing engagement and click-through rates. PostHog's strategy involves a mix of static and dynamic images, with the latter automatically generated to reduce the manual workload for designers, resulting in more informative and visually enticing previews. This project not only highlights the importance of Open Graph images in digital marketing but also underscores the potential impact of thoughtful design in capturing user attention and conveying key information quickly.
