Click Through Rate Calculator
Calculate the click-through rate (CTR) of any ad, email, or search result by entering total clicks and impressions. Use it to benchmark and optimize campaign performance.
About this calculator
Click-through rate (CTR) measures what proportion of people who saw your ad or link actually clicked on it. The formula is: CTR = (clicks / impressions) × 100, expressed as a percentage. For example, 500 clicks from 20,000 impressions yields a CTR of 2.5%. CTR is a primary performance indicator in paid search (Google Ads), display advertising, email marketing, and organic SEO. A higher CTR generally signals that your headline, ad copy, or meta title is resonating with the target audience. However, CTR should always be read alongside conversion rate — a high CTR with low conversions may indicate misleading ad copy or a poor landing page experience.
How to use
Suppose your Google search ad was shown 50,000 times last week and received 1,750 clicks. Enter Total Impressions = 50,000 and Total Clicks = 1,750. The calculator computes: CTR = (1,750 / 50,000) × 100 = 3.5%. The average Google Search CTR is roughly 2–5% for well-optimized ads, so 3.5% is a solid result. You can now compare this against last week's 2.8% CTR to confirm your new ad copy is performing better, or segment by device and keyword to find further optimization opportunities.
Frequently asked questions
What is a good click-through rate for Google Ads search campaigns?
Average CTR on Google Search campaigns typically falls between 2% and 5%, but this varies considerably by industry, match type, and ad position. Highly competitive industries like legal services or insurance can see CTRs below 2%, while niche or branded campaigns often exceed 10%. A CTR above the industry benchmark is a positive signal, but it should be interpreted alongside cost-per-click and conversion rate to determine true campaign health. Google's own benchmark reports and third-party studies (such as WordStream's industry data) are useful reference points for your specific sector.
How does click-through rate affect Google Ads Quality Score?
CTR is one of the most heavily weighted components of Google Ads Quality Score, which in turn affects your Ad Rank and cost-per-click. Google compares your CTR to expected CTR for a given keyword and ad position — if your ads are clicked more than expected, your Quality Score improves. A higher Quality Score can lower your CPC and improve your ad position without increasing your bid. This means investing time in ad copy, extensions, and keyword relevance to lift CTR has a compounding financial benefit beyond just more clicks.
Why is my email click-through rate much lower than my open rate?
Open rate measures how many recipients opened your email, while click-through rate measures how many clicked a link inside it — so CTR is always a subset of opens. A significant drop between open rate and CTR usually points to a mismatch between the subject line promise and the email body content, weak calls-to-action, too many competing links, or content that does not match the audience's intent. Industry average email CTR typically ranges from 2% to 5% of recipients (not just openers), while open rates average 20–40%. Improving CTR often means simplifying the email to a single clear CTA and ensuring the body delivers on the subject line's promise.
