What is the click-through rate (CTR)?
June 4, 2026
The click-through rate (CTR) measures the share of people who click on an element (ad, email link, Google result) compared to the number of impressions or opens. In e-commerce, it is a key indicator for judging the attractiveness of an ad, an email subject line, or a CTA before the conversion into a sale.
Summary
Definition of click-through rate or CTR
The CTR (Click-Through Rate) is expressed as a percentage:
CTR = (Number of clicks ÷ Number of impressions) × 100
Example: a Google Shopping ad displayed 10,000 times and clicked 350 times has a CTR of 3.5%.
The denominator changes depending on the channel:
The concept is better understood by distinguishing several elements: (Google Ads, Meta): clicks ÷ impressions; : clicks ÷ delivered emails (or ÷ opens for the click-to-open rate); : clicks ÷ impressions in Google Search Console; : clicks on a button ÷ visitors who saw the block (A/B test).
Useful distinctions:
The concept is better understood by distinguishing several elements: vs : CTR measures the click; conversion measures the purchase (or other final goal); vs : open = opened email; click = link clicked within the email; vs : click to buy describes a purchasing journey; CTR quantifies the clicks; vs () : CPC = cost paid per click; CTR = proportion of clicks; vs : ROAS measures ad revenue; CTR measures upstream engagement.
Why CTR is important in e-commerce
A low or decreasing CTR often signals a problem with targeting, creatives, or messaging, even before analyzing sales.
Its main effects can be seen on several levels: : Google and Meta use CTR (among other things) to evaluate ad / audience relevance; : a higher CTR can improve Google Quality Score and lower CPC; : subject line + content that generate clicks drive qualified traffic to the store; : a low organic CTR on a query may indicate an unattractive title or snippet; : CTR of a banner or product page guides CRO testing; : CTR → sessions → add to cart → order; each step is managed separately ().
Warning: a high CTR does not guarantee sales. A clickbait title can attract unqualified clicks and degrade the conversion rate or ROAS. Analyze CTR and conversion together.
Calculate and interpret CTR
CTR is always calculated using unique or total clicks depending on the platform (Google Ads often counts total clicks; email can distinguish unique clicks). Verify the definition in each tool before comparing periods.
Indicative orders of magnitude (vary greatly by sector, format, and audience):
The elements to observe are as follows: : often between 2% and 5% for brand campaigns; lower in competitive generic; : can exceed text search if product visual is relevant; : often under 2% in cold; higher in retargeting; : click-through rate typically between 1% and 5% of delivered depending on segmentation.
In practice, a Shopify store tests two Meta creatives for the same product. Creative A: 80,000 impressions, 960 clicks → 1.2% CTR. Creative B: 75,000 impressions, 1,875 clicks → 2.5% CTR. Is Creative B paused in favor of A? No: A generates more absolute clicks but B has a better CTR and, after analysis, a better ROAS. Decision: scale B, adjust landing page to convert this more engaged traffic. CTR served as a first filter, not a final verdict.
Measuring CTR with Shopify and marketing tools
Shopify does not calculate a "global store CTR", but aggregates data via channels and apps:
In Shopify, this translates in particular to: : CTR column by campaign, ad group, keyword (); : CTR (link clicks) and CTR (all clicks) to distinguish; : average CTR by page and query (SEO); : click-through rate by ; : click events, exploration reports; complete .
Tracking points of attention:
The process can be summarized as follows: first, consistent UTMs on all links (source, medium, campaign); then, Meta Pixel and Google Ads tag installed via Shopify or Google & YouTube channel; then, Compare CTR by device (mobile vs desktop): frequent discrepancy on Shopping and email; then, Cross CTR ads with Shopify Analytics conversion rate by channel.
Key points for analyzing CTR correctly
Points of vigilance include in particular: : A/B testing on visuals, titles, CTAs ("Discover" vs "Buy"); : same product, same price as the ad; : CTR brand vs non-brand, retargeting vs acquisition; : title, meta description, rich results to improve organic CTR; : a main CTA, visible button, mobile first; : monitor conversion, average basket, ROAS.
To monitor:
Points of vigilance include in particular: Comparing email CTR and Google Ads CTR without adapting the denominator; Misleading promise to inflate CTR (high bounce, dropping ROAS); Ignoring mobile CTR when 70%+ of paid traffic can come from smartphones; Confusing ad clicks and link clicks (Meta "all clicks"); Budget decision based on CTR without minimum volume (100 impressions = statistical noise).
In brief
To remember: = clicks u00f7 impressions (or emails delivered) u00d7 100; Upstream attractiveness indicator: ads, email, SEO, site CTA; Distinct from conversion rate, CPC, and ROAS; Measured in Google Ads, Meta, Search Console, ESP, GA4; Optimize CTR with creatives and targeting; validate with conversion and revenue.

FAQ
What is a good CTR in e-commerce?
There is no universal figure. Compare with your history, your industry, and the channel. An increasing CTR with a stable conversion rate is a good signal; the opposite is also true if the traffic is more qualified.
High CTR but few sales: why?
Common causes: inconsistent landing page, price or stock differs from the ad, overly broad audience, high-friction checkout. Analyze the post-click conversion rate and the mobile journey.
Email CTR: unique or total clicks?
Most ESPs display both. The unique click-through rate (one person = one click) is more representative of real engagement; total clicks include multiple clicks.
Does CTR impact Google SEO?
Google indicates that organic CTR is not a direct ranking factor, but a low-clicked snippet can signal an issue with perceived relevance. Optimizing title and description remains useful for traffic.
