formula: CTR = Clicks ÷ Impressions × 100
tl;dr
Average organic CTR for position 1 on Google is ~27%. For email subject lines, 2-5% is typical. For ads, 1-3% is decent. Improving CTR is often the fastest win — better titles and descriptions cost nothing.
Simple definition
CTR measures how effective your content is at earning a click from people who see it. It applies everywhere: search results, email campaigns, ad creatives, social media posts, and in-app prompts. For solo founders, CTR is one of the cheapest metrics to improve because the changes are free — rewriting a headline or tweaking ad copy costs nothing but can double the number of visitors or signups you get from the same impressions.
How to calculate it
CTR = (Clicks / Impressions) x 100. If your blog post appeared in Google search results 4,000 times last month and 280 people clicked through, your CTR is (280 / 4,000) x 100 = 7%. Google Search Console shows CTR per page and per query. For email, your email platform reports opens and clicks — if 1,000 subscribers receive an email and 35 click a link, your CTR is 3.5%. Always measure CTR per channel separately because benchmarks differ dramatically.
Example
Your SaaS landing page ranks #4 for "habit tracker app" with a CTR of 4.2% on 8,000 monthly impressions, bringing in 336 visitors. You rewrite the title tag from "Habit Tracker - Build Better Habits" to "Free Habit Tracker: Build a Streak in Under 2 Minutes." CTR jumps to 7.8% — now 624 visitors per month from the same ranking position. At your 6% signup conversion rate, that is 17 extra signups per month from a 5-minute title change. No ad spend, no new content, no engineering work.
