Scent is a subjective judgment of cues and may mismatch true relevance

What it is

Information scent exists in the user’s interpretation, not as an objective page-goal distance. Users treat familiar words, brands, format, social proof, and salient position as evidence of relevance; a title that “sounds like the answer” may be useless, while truly relevant content with different terminology is skipped.

Why it happens

Subjective judgment is shaped by word mapping, task representation, experience, language, and current pressure. The same label has different scent for novices and experts; marketing phrasing, recently seen words, and high ranking amplify scent. Misjudgment creates two failures: following strong scent to no benefit, or ignoring weak but truly relevant sources.

Studying it

Record user choice, actual page relevance, stated reasons, and goal attainment; compare subjective scent ratings with expert relevance ratings. Observe changes in goal statements before and after tasks. In search logs, analyze mismatches among query words, clicked labels, and final landing pages.

Where it stops holding

Subjectivity does not mean abandoning objective information architecture; it requires validating users’ language and task model. Click count alone cannot evaluate scent—clicks may be attracted by misleading cues. Personalization can strengthen scent but may create filtering bias.

Applying it

• Test labels with target users’ task vocabulary, not author judgments of relevance.
• Ensure strong-scent destinations redeem their promise quickly; when mismatched, point to nearby paths.
• Provide aliases and mappings for professional synonyms, regional terms, and legacy names.
• Analyze high-click low-conversion results for misleadingly strong scent.
