The measurement of where and how users click on a webpage, revealing which elements attract attention and which are ignored. Click tracking data helps optimize button placement, navigation design, and content hierarchy. Framer's built-in click tracking in Metrics shows exactly where visitors engage without needing external heatmap tools.

The bottom section of a webpage, typically containing navigation links, copyright information, and secondary content like contact details or social links. Footers provide a sense of closure and catch visitors who've scrolled through all content. Design footers to be useful—include key links users might need after reading your page.

The top section of a webpage, typically containing the logo, main navigation, and key actions like sign-in buttons. Headers establish brand identity and provide consistent navigation across all pages. Design headers to be useful without overwhelming—users should find what they need without excessive visual competition.

The process of reducing image file sizes while maintaining acceptable visual quality for faster page loads. Optimized images can be 10x smaller than originals without noticeable quality loss, dramatically improving performance. Framer automatically optimizes uploaded images, converting to efficient formats like WebP where supported.

The portion of a webpage visible without scrolling, borrowed from newspaper terminology where the top half of the front page was most prominent. This prime real estate should contain your most compelling content, clear value proposition, and primary call-to-action. Studies show users form impressions within milliseconds, making above-the-fold content critical for engagement.

Graphics Interchange Format—a compressed image format supporting animation and transparency, limited to 256 colors. GIFs are popular for short animations and reactions but have large file sizes. Consider modern formats like WebP or video for better compression and quality.

The process of reducing file sizes by removing redundant data, making assets faster to download and cheaper to serve. Image compression can reduce file sizes by 50-80% with minimal visual quality loss using formats like WebP. Framer automatically optimizes images for web delivery while preserving quality where it matters most.

The process of fetching and rendering a webpage, measured from request to full interactivity. Page load speed affects user experience, conversion rates, and search rankings. Monitor load performance and optimize bottlenecks regularly.
