CTR is the percentage of impressions that result in a click on an iGaming ad, creative, or organic listing, signalling creative and targeting quality.
Click-Through Rate (CTR)
TL;DR: CTR is the percentage of impressions that result in a click on an iGaming ad, creative, or organic listing, signalling creative and targeting quality.
What it means
In iGaming acquisition, CTR is the first efficiency gate after impressions. A high CTR on a Meta promo creative or a Google brand-search ad usually means the offer (e.g. "100% up to $200 + 50 FS") and audience match. Affiliates use CTR on review pages to judge whether their "Play now" buttons and operator logos are pulling weight.
CTR is also tracked inside the product — on lobby tiles, push notifications, in-game banners, and email CRM — where it tells the team whether segmentation and creative are working before deposits even enter the equation.
Formula / How it's measured
CTR = (Clicks / Impressions) × 100.
Example: a Brazilian sportsbook runs a Meta video ad seen 2,400,000 times with 31,200 clicks. CTR = 1.30%. The same operator's CRM email blast (180,000 sends, 9,000 clicks) shows CTR of 5.0%.
Why it matters for operators
CTR is the leading indicator that media is healthy — it moves days before CPA does. Underperforming creatives are killed on CTR thresholds; high-CTR creatives are scaled and rotated to fight fatigue. In SEO and affiliate pages, CTR on SERPs decides how much free traffic the brand pulls.
Common benchmarks (2026)
- Meta paid social, casino: 0.8%–1.8%
- Google brand search: 25%–55%
- Google non-brand search (sportsbook): 3%–9%
- CRM email (active players): 4%–12%
- Push notifications: 2%–6%
- Display/programmatic: 0.05%–0.25%
Common mistakes
- Optimising creatives on CTR alone — clickbait creatives boost CTR but tank FTD rates
- Comparing CTR across placements (Reels vs Feed vs Search) as if they were equivalent
- Ignoring bot/incentivised traffic that inflates CTR but never deposits
