URL parameters add information after a “?” in URLs (tracking codes, filters, sessions). Manage them properly to avoid duplicate content – use canonical tags or parameter handling in Google Search...
Read MoreUser signals include CTR, dwell time, bounce rate, and return visits – behavioral metrics that indicate content quality. While not direct ranking factors, poor user signals correlate with ranking drops....
Read MoreUGC includes comments, reviews, and forum posts. It can boost freshness and social proof but watch for spam – moderate and add nofollow where appropriate. Are you spending all your...
Read MoreIR evaluation problem: way more irrelevant than relevant documents. Biases metrics like precision/recall. Engines use weighted measures to counteract. Are you confused why your perfect article, packed with keywords, still...
Read MoreA machine learning technique: the system requests human labels for “uncertain” results to improve training. Google’s spam detection uses this principle. Are you relying on guesswork to figure out which...
Read MoreTransforming documents into standardized vector forms regardless of length/format. Important for embedding-based search engines. Are you confused why some of your content ranks perfectly and other, very similar pages disappear?...
