Measuring docs and knowledge bases today goes beyond clicks to include presence in AI summaries, featured snippet win-rate, and FAQ impression share. Track engagement quality—scroll depth, time on key sections, and conversions from high-intent queries—to confirm usefulness. Use log files and analytics to see how bots and users traverse Q&A sections, how internal links are followed, and where drop-offs occur. Over time, benchmark growth in answer-surface visibility alongside organic traffic and brand search volume.
