Is this recognisable?
Spending money zonder real returns
You invest heavily in ads, but the results lag behind. On balance, it simply does not deliver enough to meet your goals.
No focus or time
There is no elaborate strategy or space in your calendar to actively work on increasing your conversion rate, number of orders and average order value.
Growth stalled
Your webshop seems to have reached a ceiling. Sales are no longer growing and it feels like you are running into an invisible limit.
Disappointing collaborations
You have previously worked with agencies that made nice promises but delivered little. You are now looking for a CRO expert who actually delivers results and dares to 1TP15Build that.
Our approach:
SEO & CRO combined: we make sure your website not only converts better, but is also more findable in search engines, so that you get maximum results from both traffic and conversion.
- Specialist team per project: we deploy experienced onder searchers, CRO specialists, A/B test developers and experimentation leads
- Tailoring to scale and focus: we handle limited growth trajectories for optimal impact
- Full-funnel optimisation: useronder search, UX analysis, funnel and page review, onsite interaction analysis and usability audits
What is conversion optimisation?
Conversion optimisation is all about optimising the user experience so that the user 'converts' and relatively more conversion is achieved. But what then is conversion?
For webshops: a purchase, a higher order value or perhaps even repeat purchases
For lead generators (websites with 'leads' as their main goal): a lead, request for quotation, completed contact form
For content platforms: clicks on affiliate links
Conversions differ within types of websites and by industry, but within websites we also talk about different types of conversions. Think about:
- The purchase or a request for quotation
- Downloads of manuals
- Newsletter subscriptions
The ultimate goal of a conversion optimisation journey is the 'hard' conversion: the purchase or the quotation request. But there are many different steps that ultimately lead to this.
Why hire a conversion optimisation agency
An external conversion optimisation agency brings specialist knowledge, an independent view and professional tools. Reliable testing is all about accurate statistics and careful quality control.
- Objective view: external experts see areas for improvement that internal teams miss due to bias
- Advanced tools: access to premium testing software, heatmaps and analytics
- Proven methodologies: structured approach based on experience with different sectors
Why conversion optimisation combined with SEO?
At Onder, we not only help with CRO, but also SEO. As a conversion optimisation agency, we know how important it is that your website is both findable and profitable.
SEO is all about increasing organic traffic to your website. The focus here is on relevant traffic: users making searches that are close to a product or service. The moment these users do not convert or quickly leave your website, it is a waste.
There are three reasons why the combination of CRO & SEO makes sense:
- The ultimate goal of a website is central to all online marketing channels, including SEO. After all, you have no use for users from organic traffic who do not convert.
- Organic users' engagement on your website also ultimately affects your rankings in Google.
- SEO specialists are working on layout and content of different page types, performing data analysis and forming an excellent profile to also look at your website's conversion rate.
What does a conversion optimisation journey look like
A journey with our conversion optimisation agency is intensive and focused on results. We uncover the pain points towards conversion, come up with points for improvement and implement them or test them with A/B tests to verify whether the hypotheses are correct.
Phase 1 Analysis
At our conversion optimisation agency, the first phase revolves entirely around one central question: how does the user behave on your website?
With a thorough website analysis based on best practices, data and funnel analysis (Google Analytics) and behavioural analysis via tools like Hotjar and Clarity, we identify the main obstacles on all page types. In this way, we discover exactly in which parts of the website the most gains can be made and where we start working first.
The analysis forms the basis for the next step in our conversion optimisation process: determining areas for improvement and translating them into concrete test ideas and hypotheses.
Phase 2 Hypotheses (the ideas phase)
IBased on the analysis, we know where the biggest bottlenecks lie. In this idea phase, our conversion optimisation agency works on creative and data-driven solutions to improve conversion. Here, we look beyond text adjustments. Consider, for example:
- Layout changes: such as including an important item in the menu or adding a sticky menu on mobile.
- Persuasion principles: such as adding product reviews as social proof.
- Clear communication: such as placing 'Response within 24 hours' on a contact form.
We draw inspiration from previous successes and best practices from the market. Together with the client and web builder, we brainstorm, where product or service knowledge and technical expertise are indispensable.
Not every point of improvement needs to be A/B tested. Some ideas are real no-brainers and can be implemented immediately for quick results.
Phase 3 Testing
In this phase, our conversion optimisation agency tests the hypotheses to check whether they actually have an effect. Part of the visitors see the improvement point, while another part sees the initial situation. This happens in two ways:
- A/B testing: we compare the old situation with one new variant, usually in a 50/50 split.
- Multivariate testing: we compare the old situation with several new variants simultaneously to determine which performs best.
When a test has produced sufficient data and the hypothesis is confirmed, we implement the improvement permanently. For websites with high traffic, this can be done quickly, while for lower volumes it may take longer to see significant results.
For testing, we use the tool Convert. In doing so, we work closely with developers for the technical implementation as well as with product experts or service providers from the customer, so that every point of improvement is in line with practice.
Working with Onder: transparency and knowledge transfer
We work as an extension of the internal team. You stay in charge of goals and priorities, we provide onder search, design and analysis.
Transparency is standard. There is access to raw data, dashboards and test calendar in a shared environment. Tools connect to the existing stack.
Knowledge transfer is ongoing. Each test gets a full file with hypothesis, design and reusable patterns. We onder maintain a knowledge base with playbooks and components.
SEO and CRO work integrated. Test design includes SEO guardrails on organic traffic so variants respect search performance.
