However, even a steady stream of traffic means nothing if it’s not converting into paying customers, sales or clients. Optimising your conversion rate is an essential part of digital marketing, and one we know well here at Platform 81.

Our award-winning team combine their technical knowledge with appealing content and access to a network of influencers to help move your website in the right direction. By keeping on top of the latest developments, we’re able to maintain active SEO and CRO, successfully attracting thousands of qualified leads and ensuring your site delivers cost-effective conversions for years to come.

CRO vs SEO

SEO and CRO work together to drive results in the form of rankings and conversions. SEO (Search Engine Optimisation) is the process of boosting your website’s rankings in search engines’ organic results. When your site ranks at the top of search results, more people can find your business, visit your site, and ultimately make a purchase.

While SEO focuses on boosting traffic to your site, CRO aims to convert that traffic by encouraging more people to take action – whether that be signing up to your newsletter, filling out a contact form, or making a purchase. In other words, CRO helps you convert more of the traffic you drive with SEO.

Why is it important?

Search engines are constantly evolving over time. Not only is competition increasing, but guidelines are becoming more technical and page one search rankings are proving harder and harder to achieve – which is where we come in. At Platform 81, we ensure that every single component of your website helps answer searchers’ queries, moving them closer to becoming customers as a result.

Our holistic SEO and CRO services include the creation of precise title tags and meta descriptions which accurately describe what users can expect to find on your site, helping drive more relevant traffic, while seeing engagement metrics rise and bounce rates drop.

In addition to this, we focus on optimising your content for mobile, making it easier for users to find the information they need clearly and efficiently, so you don’t miss out on valuable leads and conversions. With our technical expertise and 15+ years of industry experience, your site’s credibility and visibility are all but assured.

How can Platform81 help?

SEO and CRO should go hand-in-hand to reach and convert leads. Optimising a website to rank in Google results as well as convert site visitors requires time and expert insight – something which we have plenty of here at Platform81.

By utilising CRO tools such as Google Analytics, we can collect and analyse user data, then optimise your content by including elements that convert more visitors. As campaigns progress, it allows us to invest more time in the activities that are seeing the best results.

It has been a pleasure working with the Platform81 team during our website transformation process. They have taken our rebranded assets and created a digital presence that not only showcases who we are today, but also what we aspire to be as a brand in the future too. Every aspect of the process was carefully considered and it created a great amount of peace of mind knowing our website was in safe hands. Thank you to Eve, Brad and Mark for their hard work especially.

Frequently Asked Questions

Let’s start at the beginning: what exactly is Conversion Rate Optimisation?

In short, CRO is the science of turning more of your website visitors into paying customers. You’re already spending money on marketing to get people to your site; CRO makes sure that money isn’t wasted by fine-tuning your website to make it as easy and persuasive as possible for users to take the action you want them to take.

Isn’t CRO just a load of guesswork and changing button colours?

Not at all. Any agency just guessing is having you on. Proper CRO is a data-driven process. We use tools like analytics, heatmaps, and user recordings to see exactly how people are behaving on your site. We’re like detectives, looking for clues to find out where they’re getting stuck or confused, then we form a solid hypothesis about how to fix it.

How do you know what changes to make to our site?

We let the data lead the way. If we see that 80% of mobile users are dropping off on a specific form, we’ll dig in to find out why. Is the form too long? Is a button hard to click? Based on that evidence, we’ll propose a specific, measurable change and then we test it to see if we were right. It’s a systematic process of ‘investigate, hypothesise, test, learn’.

Will you be making big, risky changes to our live website?

No. We don’t just charge in and overhaul your site based on a hunch. We use A/B testing, which means we run a controlled experiment. We’ll show the original version of a page to half your visitors, and our new, improved version to the other half. We then measure which one performs better. This way, we can prove a change works before rolling it out to everyone, removing the risk.

How long does it take to see meaningful results from CRO?

CRO is a marathon, not a sprint. While you can sometimes get a ‘quick win’ that shows an immediate uplift, the real value comes from a programme of continuous testing and improvement over several months. The first month is often about gathering enough data to find the biggest opportunities. Meaningful, business-changing results typically start to build from month three onwards.

We’re already doing SEO and PPC – how does CRO fit in?

It fits in perfectly – in fact, it makes your other marketing more profitable. Think of it this way: SEO and PPC are working hard to get people to your front door. CRO is the expert inside who makes sure the layout is perfect, the signage is clear, and the path to the till is completely frictionless. Without CRO, you’re potentially wasting a big chunk of your ad spend on traffic that never converts.

What kind of metrics do you actually report on?

We don’t bother with vanity metrics. Our reports focus on the stuff that hits your bottom line: the uplift in conversion rate, the increase in qualified leads, the reduction in cost per acquisition, and most importantly, the return on your investment. We’ll have a proper chat with you each month to explain what the numbers mean for your business.

Do we need a massive amount of website traffic to do CRO?

Not necessarily, but you do need enough to get statistically significant test results in a reasonable timeframe. If your traffic is on the lower side, we might start with analysing user behaviour and making improvements based on best practice and qualitative data first, before moving on to full A/B testing as your traffic grows. We’ll be straight with you about what’s possible with the numbers you have.
