What CTR actually tells you
Click-through rate is clicks ÷ impressions × 100 — the share of people who saw your link and clicked it. For an affiliate site, "impressions" is usually the pageviews on the page carrying the link, so your affiliate-link CTR is link clicks divided by pageviews. It measures one specific step: getting a visitor from reading to clicking out.
CTR is half of what a visitor is worth
On its own, CTR doesn't pay you — it's the bridge between traffic and clicks. Multiply it by EPC and you get revenue per visitor: RPV = CTR × EPC. That single equation is why two pages with an identical EPC can earn wildly differently — the one that gets more of its visitors to click has the higher CTR, and so the higher RPV. Raising CTR is often the fastest lever you have, because it's entirely on your side of the transaction.
Where CTR sits in the funnel
Don't confuse CTR with conversion rate. CTR is view → click (your job: placement, relevance, calls to action). Conversion rate is click → sale, which happens on the merchant's side. Both feed your revenue per visitor, but you have far more direct control over CTR — which is why comparing your placements' CTR, as the tool above does, is usually the first optimization worth making.
Frequently asked questions
How do I calculate click-through rate?
CTR = clicks ÷ impressions × 100. If 45 people clicked out of 3,000 who saw the link, that's 45 ÷ 3,000 = 1.5%. For affiliate links, 'impressions' is usually the pageviews on the page where the link appears, so affiliate-link CTR is link clicks ÷ pageviews.
What counts as a good affiliate CTR?
It depends heavily on context — an in-content link inside a buyer-intent review behaves very differently from a banner. Rather than chase a universal benchmark, compare your own placements against each other and track the trend. What matters is that CTR is one half of revenue per visitor: the other half is EPC, and RPV = CTR × EPC.
How does CTR relate to earnings?
CTR alone doesn't pay you — it's the bridge between traffic and clicks. Multiply it by EPC (earnings per click) and you get revenue per visitor: RPV = CTR × EPC. That's why two pages with the same EPC can earn very differently — the one that gets more visitors to click has the higher CTR, and therefore the higher RPV.
What's the difference between CTR and conversion rate?
CTR measures the step from view to click (did the visitor click your link?). Conversion rate measures the step from click to sale (did that click become a purchase?). In affiliate terms, CTR gets the visitor to the merchant; conversion rate — and the commission — happens on the merchant's side. Both feed your overall revenue per visitor.
