Information scent
What is information scent?
Information scent is how strongly a link or label hints that it leads to what you're after. Like an animal following a trail, people follow the cues that smell most like their goal - so clear, goal-matching labels pull them confidently forward, while vague ones leave them sniffing around, unsure which way to go.
Also known as: information scent, info scent, information foraging

The demo
Your task: find where to cancel a subscription. Here's the menu, twice. First with vague labels, then with labels that actually smell like the goal. Click the one you'd try.
What this demo shows (text version)
The task is to find where to cancel a subscription. The same menu is shown twice. With weak scent the labels are vague - "Options", "More", "Account" - so none of them clearly smells like the goal and you have to guess, often picking the wrong one first. With strong scent the labels are specific - "Billing and subscription", "Cancel subscription" - so the right path gives off a clear scent and you go straight to it.
That's information scent: people forage for information by following the cues that most resemble their goal, and they hesitate or give up when the scent is weak. The fix is to label links for the destination in the user's own words, so every click visibly gets warmer rather than leaving people sniffing around.
People navigate by scent, not by maps. At each step they pick the link whose words best match what they want, and they keep going only while the scent stays strong. Weak, clever or generic labels ("Options", "More", "Solutions") give off no scent, so people hesitate, backtrack or give up; specific labels that echo the user's own words ("Cancel subscription", "Track my order") give off a strong scent and pull them straight through. Label links for the goal they lead to, in the user's language - not for your internal structure or your brand voice.
With vague labels you had to guess and poke around - no link smelled like the answer. With scented labels the right path almost announced itself, because the words matched what you were looking for. That's information scent: people follow the cues that resemble their goal, so the clearer the label points at the destination, the faster and more confidently they move.
Information scent comes from information foraging theory: people forage for information much as animals forage for food, following the strongest trail and abandoning a "patch" when the scent fades. At every link they make a quick judgement - does this look like it leads toward my goal? - and weak scent (a label that could mean anything) makes that judgement fail, causing hesitation, wrong turns and drop-off.
Strong scent comes from labels that mirror the user's goal and vocabulary: "Returns and refunds" beats "Help", "Cancel subscription" beats "Manage", "Pricing" beats "Solutions". Trigger words the user already has in mind, descriptive link text, breadcrumbs and clear category names all keep the trail warm; clever, branded or internal-jargon labels break it. Search snippets, menu items and buttons all live or die on their scent.
Design navigation by following real goals through it: for each task, can the user smell the right next step at every screen without guessing? Use words from user research rather than the org chart, keep link text specific, and make sure each click visibly gets warmer. Weak scent is a leading cause of people failing tasks on sites that technically contain exactly what they need.
