This article takes a deeper look at how to optimise your click-through rate (CTR), an essential component of conversion rate optimisation. An optimised title tag alone can increase CTR by +14.1% (Onesty, 2026).
CTR stands for Click-Through Rate. In digital marketing, it is one of the most important performance indicators. This KPI enables you to assess the relevance and effectiveness of many types of campaigns: paid advertising, SEO, email marketing, retargeting, and more.
What Is CTR?
This metric measures the number of people who clicked on a piece of content (such as an ad, a CTA, or a link) relative to the number of impressions (i.e., how many people saw it). Click-through rate applies to a wide range of clickable elements: an email, a landing page, a Google Ads advert, a SERP listing, a blog post, and so on. That is precisely why CTR matters: it tells you whether campaigns designed to drive clicks are actually working.
A Practical Example
Imagine an advert receives 10,000 impressions. If 100 people click the link, the CTR is 0.01. Multiply by 100 to express it as a percentage: 1%. Typically, only unique visitors are counted to prevent a single user clicking multiple times from skewing the results.
The Right Tools
Trying to calculate CTR manually — let alone track it across multiple campaigns — is simply not practical. Tools such as Google Analytics, Google Search Console, or Incremys, when properly configured, can measure CTR and generate detailed reports to identify the strengths and weaknesses of your strategies. Incremys also offers dedicated modules to help optimise CTR and improve conversion performance, notably via Personalised AI, content production, and the performance reporting module, supporting businesses in the continuous improvement of their digital results.
How to Interpret a Click-Through Rate
"What is a good CTR?" is one of the most common questions in digital marketing. It is difficult to give a universal answer, because the quality of a click-through rate depends on several factors.
Your Industry
The sector in which your business operates is a key variable, as some industries lend themselves more naturally to search behaviour than others. Optimising CTR is not about chasing identical benchmarks across every market. There are considerable disparities, as illustrated by the examples below:
- Pets: 6.45%
- Lawyers and legal services: 3.84%
- Leisure: 10.67%
- Home equipment: 4.21%
- Travel: 8.54%
Your Acquisition Channel
CTR varies significantly by channel. In Google Ads, average CTR for Search campaigns is around 3.17%, while on the Display Network it can be as low as 0.46%. In email marketing, average click-through rates typically hover around 2.5%. For SEO, performance depends heavily on the quality of your optimisation efforts and, crucially, your position in the SERP.
Brand Awareness
It stands to reason that a well-established brand will enjoy an above-average CTR. If you have just launched and are running your first advertising campaign, do not expect instant results. In that context, a CTR between 1% and 2% is perfectly respectable.
Other KPIs to Consider
Whilst CTR is an important indicator, it must be analysed alongside other data. Cost per click and conversion rate (it is worth distinguishing SEO conversion rate from paid conversion rate) both come into play. For instance, if you run an e-commerce site, a 5% CTR paired with a 10% conversion rate is far more valuable than a 30% CTR that generates no sales whatsoever.
Why and How to Optimise CTR
There is no one-size-fits-all approach to optimising CTR. It depends entirely on the marketing channel you are working with.
Paid Advertising
In paid search, CTR is particularly telling: a high rate suggests users consider your advert relevant to their needs. It also validates upstream decisions, particularly around keyword selection. In this context, CTR serves another purpose: a strong CTR can improve Google's quality score for your advert, potentially securing better placements and reducing your cost per click — thereby improving overall campaign efficiency.
CTAs
Call-to-action buttons on a website have a clear influence on conversion rate and should never be neglected. To optimise CTR in this context, your CTA needs to stand out, be easy to read, and be positioned strategically on the page.
SEO
Optimising CTR also applies to organic search. A listing with a strong click-through rate sends a positive relevance signal, and Google's aim is to deliver satisfying results to its users. By publishing content that is genuinely useful, high quality, and closely aligned with the user's search intent, your click-through rate has every chance of improving significantly.
Email Campaigns
In email marketing, CTR should be assessed alongside another KPI: CTOR (Click-to-Open Rate). For someone to click a link in an email, they first need to open it. For a clearer picture of link performance, CTOR is often the more meaningful metric. For example, 100 clicks from 1,000 emails sent gives a CTR of 10%. But if only 500 recipients opened the email, the CTOR is 20%.
In Summary
Optimising CTR is an absolute must in marketing. That said, as we have explored, click-through rates are not directly comparable across channels and depend on a range of factors. Be careful not to overinterpret this metric in isolation.
Optimising CTR in the Age of AI Overviews
In SEO, CTR is directly affected by Google's AI Overviews. At position 1, CTR drops from 34% without an AI Overview to just 2.6% when one is present (Seer Interactive, 2025). This dramatic fall means CTR optimisation strategies must evolve to incorporate the GEO dimension.
- CTR and AI Overviews: The CTR for position 1 drops sharply when an AI Overview is displayed. However, being cited within the AI Overview can partially offset the loss: it brings brand visibility and more qualified traffic, even if overall click volume declines.
- Optimising snippets for AI: Title tags and meta descriptions that provide a direct, data-backed answer are more likely to be picked up by AI Overviews. What improves traditional CTR — clarity, clear value, specific numbers — also improves your chances of being cited by AI.
- Post-citation CTR: A new KPI is emerging: the click-through rate after exposure to an AI citation. Pages referenced in an AI Overview that still differentiate their title from the AI summary are better placed to win clicks from users who wish to explore the topic further.
The Incremys reporting module tracks CTR by SERP type (with or without AI Overviews) so you can manage snippet optimisation with greater precision.
Frequently Asked Questions
What Is CTR and How Do You Calculate It?
CTR (Click-Through Rate) is the ratio of clicks to impressions, expressed as a percentage. Formula: (clicks / impressions) × 100. In SEO, average CTR for position 1 is 34% (SEO.com, 2026). In Google Ads, average Search CTR is 6.45%. A good CTR depends on ranking position, industry, and the type of result displayed.
How Can You Optimise CTR in SEO?
Key levers include: writing compelling title tags (incorporating the main benefit and a specific figure), crafting engaging meta descriptions with a clear call to action, using structured data to earn rich snippets (star ratings, FAQs, prices), targeting featured snippets, and testing different formulations in Search Console to identify which versions attract the most clicks.
What Impact Do AI Overviews Have on CTR?
When an AI Overview appears, CTR for position 1 drops from 34% to 2.6% (Seer Interactive, 2025). The impact is greatest for informational queries and lower for transactional ones. To compensate, being cited within the AI Overview itself is becoming a key lever: cited pages capture brand visibility even without a direct click.
What Is the Difference Between CTR and CTOR in Email Marketing?
CTR measures clicks relative to impressions (or emails sent, depending on the tool), whilst CTOR (Click-to-Open Rate) measures clicks only among opened emails. To optimise email CTR effectively, analyse both: a strong open rate paired with a low CTOR often points to weak content or a poorly crafted CTA, whereas a high CTOR with a low open rate more typically indicates an issue with the subject line, sender reputation, or deliverability.
What Are Quick Wins for Increasing CTR in the SERP?
To optimise CTR quickly, start with pages already ranking well (positions 3–10) and: add a clear benefit in the title, include a differentiating element (a number, year, or method), align your wording with search intent, and rewrite the meta description as a promise + proof + a light call to action. Where relevant, add structured data to earn rich snippets.
Which Metrics Should You Track Alongside CTR to Avoid False Gains?
A higher CTR does not necessarily translate into more business. To validate CTR improvements, also monitor: conversion rate (SEO/PPC), bounce rate or engagement, value per session or leads generated, and average ranking position. The objective is more qualified clicks, not simply a higher volume.
How Do You Prioritise Pages to Optimise for Better CTR?
Prioritise URLs with high impressions but a CTR below the average for their position (visible in Search Console). Then focus on queries where you are already on page one: small snippet improvements typically produce faster results there. To scale the process, segment by SERP type (with or without AI Overviews) and by intent (informational versus transactional).
How Can Incremys Help Optimise CTR (SEO and GEO)?
Incremys helps you optimise CTR by identifying high-potential queries (high impressions, underperforming CTR), generating intent-driven briefs to improve title tags and meta descriptions, and tracking performance by SERP type (including with or without AI Overviews) via its reporting module. The approach combines SEO and GEO to maximise visibility, even when click volume declines but AI citations increase.
