SERP Click-Through Rate Calculator
Estimate the click-through rate your page will earn at a given SERP position, factoring in query type, rich snippets, and device. Use it to forecast organic traffic or justify moving from rank 5 to rank 3.
About this calculator
Click-through rate in search results follows a power-law decay — each lower position captures exponentially fewer clicks. The core formula is: CTR (%) = max(0.1, position^(−0.8) × 32.5 × queryTypeMultiplier × snippetMultiplier × deviceMultiplier). The exponent −0.8 models the steep drop-off observed in large-scale CTR studies. Position 1 typically earns ~32.5% CTR on a neutral query; position 10 earns roughly 4.1%. Query type adjusts for navigational queries (higher CTR) versus informational or commercial (lower, as SERP features absorb clicks). Rich snippets like star ratings, FAQs, or sitelinks can increase or decrease CTR depending on context. Device type accounts for mobile users seeing fewer organic results above the fold.
How to use
Suppose you rank at position 3 for a commercial query (multiplier 0.85), have a rich snippet (multiplier 1.15), on desktop (multiplier 1.0). CTR = max(0.1, 3^(−0.8) × 32.5 × 0.85 × 1.15 × 1.0). First: 3^(−0.8) = 1 / 3^0.8 = 1 / 2.408 = 0.415. Then: 0.415 × 32.5 = 13.49. Apply multipliers: 13.49 × 0.85 × 1.15 = 13.49 × 0.9775 = 13.19%. Your estimated CTR is 13.19% at position 3 with those features.
Frequently asked questions
What is the average click-through rate for position 1 in Google search results?
Studies by Backlinko, Advanced Web Ranking, and others consistently show position 1 captures between 27–32% of all clicks for a given query, though this varies significantly by query type and SERP layout. Branded and navigational queries tend to have even higher position-1 CTRs because users are actively seeking a specific site. Informational queries with featured snippets or knowledge panels can divert clicks away from position 1 organic results, sometimes dropping CTR below 20%.
How do rich snippets affect organic click-through rates in Google?
Rich snippets — including star ratings, FAQ dropdowns, recipe cards, and sitelinks — make listings more visually prominent and informative, generally increasing CTR by 10–30% depending on the feature. However, expanded featured snippets and 'People Also Ask' boxes can reduce CTR for standard blue-link results by answering the query directly on the page. The net effect depends on the specific snippet type and whether it satisfies or amplifies user curiosity.
Why does device type change SERP click-through rates?
Mobile and desktop SERPs are structured differently. Mobile screens show fewer organic results above the fold, and local packs, ads, and featured snippets take up proportionally more space on smaller displays. This compresses the CTR advantage of top positions on mobile while making positions 4–10 even less visible. Desktop users also tend to engage in more deliberate research sessions, whereas mobile queries often trigger immediate action — meaning CTR patterns differ by both screen size and user intent.
