Example 2: Email subject lines

A sales team sends cold emails with a 2% click rate. They test subject lines that ask a question versus subject lines that make a claim. The question format wins with a 3.5% click rate.

Click rate measures how many people click on your content after seeing it. You work it out by dividing clicks by impressions and multiplying by 100.

A click rate of 2% means that for every 100 people who saw your thing, two clicked through to learn more.

It tells you one thing: how compelling your message is. A low click rate means your headline, ad creative, or subject line is not grabbing attention. A high one means your hook is working.

Say you're running a webinar landing page in Unbounce and the headline draws plenty of traffic but few sign-ups. That weak click rate on your call-to-action is the page telling you the offer or the button copy needs work, long before you spend a penny more on ads.

Say you send a product-update newsletter through Brevo. The open rate looks healthy, but the click rate on your main link is flat. That gap means people open it and shrug, so the body and the link itself, not the subject line, are what to fix.

Or say you're running a cold-email sequence in Lemlist. The click rate on your booking link tells you whether your pitch actually lands, one step before you judge replies.

Benchmarks differ wildly by channel. A LinkedIn ad might average 0.5% while a well-targeted email could hit 5% or more, so compare like with like, never across channels.

Click rate is the bridge between visibility and traffic. You can have millions of impressions, but if nobody clicks, they are worthless. Lifting your click rate is often the fastest way to grow traffic without spending more on ads.

How to apply

Calculate click rate for each channel separately:

Click rate = (Clicks / Impressions) × 100

Track this weekly. Look for trends. A declining click rate means your creative is getting stale or your audience is fatigued.

To improve click rate:

  • Test different headlines and hooks
  • Make your offer clearer and more specific
  • Use social proof in your ad copy
  • Ensure your visuals stand out in the feed
  • Refine your targeting to reach more relevant people

Run A/B tests with one variable at a time. Test headlines first, then images, then calls to action.

Why it matters

audience is seeing you but not responding. That means your hook, headline, or offer is not compelling enough.

Improving click rate has a multiplier effect. If you double your click rate, you double your traffic without increasing ad spend. That makes every euro you spend on impressions more efficient.

Click rate also helps you diagnose problems. If traffic is down but impressions are stable, the issue is click rate. If click rate is stable but traffic is down, the issue is impressions. Knowing this tells you where to focus.

Example 1: LinkedIn ad optimisation

A SaaS company runs LinkedIn ads with a 0.4% click rate. They test a new headline that leads with a specific pain point instead of their product name. Click rate increases to 0.7%, nearly doubling their traffic.

Example 3: Organic social hooks

A consultant posts on LinkedIn with an average 1.5% click rate on posts with links. They test opening with a bold, contrarian statement. Click rate jumps to 2.8% because the hook stops people scrolling.
