Term : Click-Through Attribution Credits : Conversions after an actual click Versus : View-through (impression-only) credit Knob : The lookback window length ## Forms & parts of speech click-through attribution · noun Click-required credit. "On **click-through attribution** alone, the display campaign vanished - every 'conversion' had been view-through." ## Definition in plain terms Click-through attribution is the rule that a conversion gets credited to an ad only if the user actually clicked that ad within a defined lookback window — clicked Tuesday, bought Friday, campaign credited. It is the stricter half of platform attribution's two-channel accounting, opposite VIEW-THROUGH ATTRIBUTION, which credits ads the user merely saw. The distinction sounds technical and decides budgets: the same campaign can look heroic or pointless depending on which kinds of credit the report admits. ## The mechanics Mechanically, the platform logs the click (a click ID, a matched identifier), and when a conversion arrives within the lookback window — commonly 7 or 30 days for clicks — the conversion joins the click and the campaign takes credit (with CONVERSION LAG meaning recent cohorts are always still filling in). The window is a real decision: too short and considered purchases fall off the books; too long and stale clicks harvest credit from demand they barely touched. Click-through's claim to rigor is the intent signal — a click is an action, so the connection between ad and buyer is at least behavioral, not merely optical. But rigor has degrees, not absolutes. A click does not prove causation (the branded-search click from someone already coming was still a click — the gap CONVERSION LIFT testing exists to expose), fat thumbs and accidental mobile taps count, and CLICK FRAUD manufactures the signal outright. The practical reading discipline: know each platform's default mix (many report click-through and view-through summed unless told otherwise), compare channels only on matched settings — judging a clickable search format against a glanceable display format requires separating the credit types — and treat click-through numbers as the floor of plausibility, view-through as the speculative layer, and lift tests as the truth serum. ## When it matters Click-through attribution matters whenever channels are compared or budgets reallocated, because mixed credit types make every comparison apples-to-noise. It matters most for channels at the extremes — search lives almost entirely on clicks while display and video lean on views, so the credit rules ARE the channel comparison. The discipline is to fix the settings before reading the chart: separate click-through from view-through in every report, match windows across platforms as closely as their tools allow, and calibrate the whole click-based ledger against periodic incrementality tests — a click connects an ad to a buyer, but only an experiment connects it to a sale that needed the ad. **Worked example.** A retailer's display vendor reports 2,200 monthly conversions and renews on the strength of them. An analyst splits the credit types: 140 conversions are click-through; 2,060 are view-through, credited because an impression rendered somewhere on a page the buyer once scrolled. That is not proof of fraud - but it is a different claim, and the team prices it differently. Click-through conversions get valued from the behavioral connection, view-through gets discounted pending proof, and a geo-holdout test settles the question: the display program drives real lift equal to roughly 600 of the claimed conversions - four times the click-through floor, a third of the blended claim. The renewal proceeds at a budget sized to tested lift, reporting permanently separates the two credit columns, and the vendor's next QBR argues about experiments instead of adjectives. **Failure modes to watch.** Reading platform totals that silently sum click-through and view-through credit; comparing a click-native channel against a view-native one on mismatched rules; windows set by default instead of by purchase-cycle reality; forgetting accidental taps and click fraud inflate the 'rigorous' column too; and promoting click-through credit to causation without lift testing. ## Synonyms & antonyms ### Synonyms click-through attributionclick-based attributionpost-click attribution ### Antonyms view-through attributionimpression credit ## Origin & history Click-through attribution descends from the click-tracking that made early digital advertising auditable — the click was the first countable proof an ad reached a human, and crediting conversions to clicked ads followed naturally. The click/view split hardened into standard platform accounting as display advertising needed a credit mechanism for ads nobody clicks.

How long should a click-through window be? : Long enough to cover your real purchase cycle (platform lag reports show the distribution) and short enough that stale clicks don't harvest credit — 7 to 30 days are common defaults, not laws. Is click-through attribution proof the ad worked? : No — a click shows behavioral connection, not causation; branded-search clicks from already-decided buyers still count, so calibrate click-based numbers with incrementality tests. ## Related tools & calculators - tool[A/B test sample size](/tools/a-b-test-sample-size/) ## Resources & people to follow - reference[Wikipedia — Attribution (marketing)](https://en.wikipedia.org/wiki/Attribution_(marketing)) - referencePlatform attribution-settings documentation (Google, Meta) - referenceRGM analysis — click-through is the floor of plausibility, view-through the speculative layer, lift tests the truth serum Curated, non-competitor resources verified per term. ## Related training - module[Performance marketing](/training/performance-marketing-foundations/) ## Disciplines Areas of marketing where click-through attribution is a core concern: [Performance marketing](/training/performance-marketing-foundations/)[Growth strategy](/training/growth-marketing-foundations/) ## Read next ## Related terms [View-through attribution](/glossary/view-through-attribution/)[Attribution window](/glossary/attribution-window/)[Marketing attribution](/glossary/marketing-attribution/)[Conversion path](/glossary/conversion-path/)[CTR](/glossary/ctr/) ## Sources 1. trends[Google Trends — "click attribution"](https://trends.google.com/trends/explore?q=click%20attribution&date=today%205-y)
