TL;DR
SEO brings people in. CRO turns them into leads. But too many teams treat them as separate jobs, and that’s where performance stalls. To get consistent results, you need one joined-up strategy with shared goals, joint planning, and updates reviewed for both rankings and user experience. When SEO and CRO support each other, your traffic becomes more valuable and your site actually converts.
Someone on your team says conversions are down.
Someone else blames the traffic.
Then comes the awkward silence while everyone pretends they know which numbers to check next.
You’ve got pages that rank but don’t convert, others that convert but get no traffic, and no clear view of where the problem actually is.
That’s usually where things stall.
This guide is for the marketers stuck in that gap, trying to grow traffic and leads without knowing how SEO and CRO are meant to work together.
What is SEO?
SEO (Search Engine Optimisation) is how businesses increase their visibility on search engines like Google, helping more potential customers discover their website. It involves making specific improvements to your website and content so that Google clearly understands what you offer, sees your website as trustworthy, and ranks your pages higher in relevant search results.
There are many ranking factors that you should consider for improving SEO, but the most talked about are:
- Keyword research: Identifying keywords your audience uses when searching online, so you know what language your website needs to speak to connect with customers.
- Content optimisation: Ensuring the words, images and layout of your web pages align precisely with what users are looking for, clearly answering their questions or solving their problems.
- Technical SEO: Making behind-the-scenes improvements like faster loading times, clear website structure and mobile compatibility, so both Google and your users find your site easy and fast to use.
- Link building: Getting other respected websites to link to yours. Google sees these backlinks as proof your site is reputable and relevant, giving your pages a boost in rankings.
Together, these elements help your website rank higher, attract more visitors who genuinely care about your products or services, and ultimately bring more potential customers to your door.
What is CRO marketing?
Conversion Rate Optimisation, or CRO, focuses on what people do once they land on your website. It’s how you guide visitors towards a specific action, like buying a product, filling out a form or downloading a brochure.
The goal is to make your website easier to use and more convincing, so more people take the action you want. That could mean rewriting a headline that isn’t clear, moving a call to action higher up the page or removing unnecessary steps from a form.
To successfully complete SEO conversion optimisation, you look at how visitors behave, find the points where they hesitate or drop off, and make targeted changes to fix the problem. Usually, your mission is to remove friction, so more of your existing traffic turns into leads or customers.
Things you can do to improve CRO optimisation
- Behaviour tracking: Tools like heatmaps, scroll depth, and session recordings show how people interact with your site, so you can spot what’s working and where things start to fall apart.
- Content clarity: Tweaking your wording, structure or visuals so people understand what you offer and how to take action. Confusion is one of the biggest conversion killers.
- Page layout and design: Simplifying how information is presented, removing distractions, and placing key messages or calls to action where people actually notice them.
- Form improvement: Making forms shorter, clearer, and less annoying to fill in. The easier it is to complete, the more people will do it.
- User journey flow: Ensuring the next step on each page makes sense. Whether that’s learning more, comparing services or getting in touch, the path should feel obvious.
- A/B testing: Trying different versions of pages or elements (like headlines or buttons) to see which ones lead to more conversions. Small changes can lead to big improvements when they’re backed by real data.
SEO vs CRO: What’s the difference?
SEO helps people find your website in the first place. CRO helps those people do something useful once they get there.
Think of SEO as the work that gets you seen on Google. If no one’s clicking through to your site, or your pages aren’t showing up when people search for services like yours, that’s an SEO problem.
CRO takes over after that click by making sure visitors land on a page that makes sense, gives them the information they were looking for and makes it easy to take the next step.
Essentially, SEO brings people in, and CRO moves them forward. You need both working together to get consistent results.
High traffic without conversions wastes your budget, and a great user journey without visitors goes nowhere.
Why you need a strategy that brings SEO and CRO together
Often, marketing teams focus on one and forget the other. Or worse, they try to do both, but treat them like separate tasks. One person’s buried in search rankings and content plans. Another’s deep in landing page layouts, conversion blockers, and user behaviour heatmaps. And no one’s asking if these two things are helping each other or getting in the way.
It happens all the time.
You spend months improving your SEO. Rankings climb, traffic goes up and reports look great. But your conversions are flat and leads are still low. Usually, this is because the page that ranks well doesn’t actually convert.
This could be for many reasons, but it could slow page loading, content written for search engines, not humans, no continuity from meta title and description to landing page or less-than-impactful CTAs.
Alternatively, you could’ve refined your landing pages until they’re lean, sharp and persuasive, but you’ve got no one seeing them because they’re buried on page 4 of SERPs.
We’ve got news for you – SEO and CRO aren’t separate jobs. They’re parts of the same journey. When they work together, your pages attract the right people and give them a reason to act, so your traffic becomes more valuable and your efforts deliver real results instead of vanity metrics.
7 ways to successfully integrate SEO and CRO
To get better results from your marketing, SEO and CRO need to work together from the start. That means treating your website as one joined-up experience — from the moment someone searches to the point they take action. Here’s how to do that in practice.
1. Agree on a shared outcome
Start by getting clarity on what success means. If SEO is focused on bringing in more traffic and CRO is working on boosting form completions or signups, the two teams need to work towards the same end goal. That might be increasing qualified leads, improving cost per acquisition or generating revenue from organic search. Without this alignment, it becomes difficult to prioritise the right work.
2. Review your top pages properly
Pull a list of your highest traffic pages and compare that with your top converting pages. You’ll usually find a mismatch. Some pages rank well but don’t generate results. Others convert well but barely get found. This is where SEO and CRO overlap the most. These pages should be the first to review and refine together.
3. Spot and fix the points of conflict
Changes made to improve one area can damage the other. Removing copy to tidy a page can weaken its relevance for search. Adding too much keyword-heavy content can make a page harder to use. The goal is to avoid working in silos. Every update should be reviewed for its impact on visibility and usability together.
4. Match the content to the intent
When someone searches, they have a goal in mind. Your SEO strategy helps you show up for that search. Your CRO efforts should then guide the visitor to the next logical step based on what they came to do. If the content doesn’t meet the intent, they will leave regardless of how well the page ranks.
5. Use both sets of data to understand what’s working
SEO data tells you how people found the page. CRO data shows you what they did once they arrived. Together, they give you the full picture. If a page is getting strong traffic but nothing happens after the click, CRO needs attention. If a high-converting page has barely any traffic, it may need better optimisation or internal linking.
6. Plan and measure updates as a team
Whether you’re testing new copy, changing layouts or adding new sections, the impact should be measured across both SEO and CRO metrics. A design change that improves conversions but causes a drop in rankings creates a new problem. The same applies in reverse. Joint planning helps you avoid short-sighted wins.
7. Collaborate from the start, not as an afterthought
Working together doesn’t mean handing a finished page from one team to the other. It means involving both early on. When you plan a new landing page or content update, SEO and CRO should shape it together. This helps avoid rework later and creates pages that drive the right traffic and move visitors to act.
4 common mistakes (and how to avoid them)
1. Focusing on one without the other
Incredibly, one-in-five marketers say they don’t have a CRO strategy. So, clearly, plenty of teams put all their effort into getting more traffic, but barely think about what happens after someone lands on the site. Others obsess over conversion rates but ignore the fact that no one is visiting the pages they’re testing. Optimising one without the other limits your results. Make it a habit to check both.
2. Treating SEO and CRO like two separate jobs
When SEO and CRO are handled by different people, teams or agencies, they often run on parallel tracks. One team makes changes that hurt rankings. The other tweaks pages without considering what people searched for in the first place. Avoid this by working from the same brief, sharing results and reviewing changes together.
3. Making assumptions without looking at data
It’s easy to rely on gut instinct. Someone decides the button needs to be red. Someone else says the content is too long. But without looking at actual search data or visitor behaviour, you’re just guessing. Use SEO tools to see how people find your site and use CRO tools to see what they do once they’re there. The data tells you what matters, so use it.
4. Trying to fix everything at once
When you realise your site isn’t converting, or your traffic isn’t growing, it’s tempting to rip everything apart and start again. That usually causes more problems than it solves. You need to work methodically and tweak. Remember: SEO takes time. So, we recommend starting with the pages that have the most potential – high traffic and low conversions, or strong conversions and weak traffic, and go from there.
Useful tools for SEO and CRO
You don’t need a stack of complicated software to improve your site. Just a few reliable tools that help you understand what people are searching for, how they behave once they land, and what’s holding them back from converting. Also, you don’t need all of the tools we’re about to mention, you can pick and choose.
Google Search Console
Google Search Console is the best place to see how your site shows up in search results. It gives you real search terms your visitors used, how many people saw and clicked each page, and whether Google is struggling to access anything. If your rankings have dropped or a page isn’t getting picked up, this is where you’ll find out why.
Ahrefs or Semrush
Both tools are solid for keyword research and tracking how your site compares to others in your space. You can see where your competitors are ranking, which backlinks they’ve earned, and which keywords are worth targeting based on traffic potential and difficulty. If you’re planning new content, this is where you start.
Screaming Frog
Instead of guessing whether your site has technical issues, Screaming Frog gives you a full report. It picks up broken links, duplicate pages, slow load times and missing metadata. It’s a bit dry, but ideal for understanding what’s going on under the surface.
AnswerThePublic or AlsoAsked
If you want to create content that actually answers your audience’s questions, these tools show you what people are typing into Google. You’ll get real search queries in their own words, grouped into topics and follow-up questions, so you can build out pages that match their intent.
Hotjar or Microsoft Clarity
These help you understand what users do once they arrive. Heatmaps show where people click and scroll. Session recordings let you watch how visitors navigate and where they give up. If your site is getting traffic but not converting, this is where you find the friction.
Google Analytics (GA4)
Google Analytics is still the go-to for understanding how people move through your site. It tells you which pages they land on, how long they stay, and where they drop off. You’ll also be able to track goals like form submissions, helping you see which pages are pulling their weight.
Optimizely or VWO
These tools let you test changes properly, rather than guessing. You can try different versions of a headline or layout and measure which one leads to more conversions.
Typeform or HubSpot Forms
Sometimes forms are the barrier, so you need tools that let you build cleaner, simpler forms and test small changes that can have a big impact. Shorter fields, clearer labels or just better placement can often lift your conversion rate without changing anything else on the page.
Frequently Asked Questions (FAQs)
What is CRO in SEO?
CRO in SEO refers to using Conversion Rate Optimisation practices on pages that already rank well in search engines. The goal is to improve how many visitors take action after arriving from search, like filling in a form, signing up or making a purchase. It helps turn organic traffic into actual results.
Is SEO part of CRO?
No. SEO and CRO are two different areas of digital marketing. SEO is about getting people to your website through search engines. CRO is about improving your website so more of those visitors convert once they arrive. They work best when used together, but one doesn’t sit inside the other.
What is a CRO strategy?
A CRO strategy is a plan to increase the percentage of website visitors who complete a goal, such as submitting an enquiry or buying something. It usually includes analysing user behaviour, identifying barriers to conversion, improving key pages and testing different versions to see what works better.
How do you calculate conversion rate?
Conversion rate is calculated by dividing the number of people who completed a goal by the number of visitors, then multiplying by 100.
So if 50 people filled in your form out of 1,000 visitors, your conversion rate is (50 ÷ 1000) × 100 = 5%.
Does conversion rate help SEO?
Not directly. A high conversion rate doesn’t improve your rankings, but the changes you make to improve CRO SEO, including better page structure, clearer messaging and faster load times, can lead to lower bounce rates and better engagement, which do support SEO performance.
What is a good conversion rate?
That depends on your industry, offer and traffic source. For lead generation websites, 2–5% is often considered normal. For e-commerce, it might be closer to 1–3%. But “good” is relative—what matters more is whether your current rate is improving and whether your traffic is converting profitably.
The easiest way to generate more traffic and conversions
In marketing, as in life, balance is everything.
SEO and CRO should be used as complementary tools for driving sustainable online growth. By attracting relevant visitors through SEO and converting them efficiently through CRO, your marketing efforts achieve more than the sum of their parts.
So, rather than debating which strategy matters more, focus on integrating both. After all, traffic without conversions is just noise, and great conversions without traffic are impossible.
If all of this sounds a bit much to untangle, don’t worry. A good place to start is with an SEO audit. Our SEO agency offers detailed audits and free SEO proposals to help you spot where your site is falling short—and what to focus on first.
