👉 Thumbnail engineering is a specialized process within digital marketing and SEO that focuses on creating optimized, high-quality images (thumbnails) for web pages to enhance user experience and improve search engine rankings. It involves selecting or generating images that accurately represent the content of the page, are visually appealing, and include relevant keywords to increase click-through rates from search engine results. Effective thumbnail engineering considers factors such as image size, aspect ratio, text overlays, and color contrast to ensure the thumbnails are clickable and engaging. By doing so, it helps in attracting more visitors to the site, increasing engagement, and ultimately boosting the site's visibility and traffic.
