Conversion rate optimisation FAQs

What is conversion rate optimisation?

Conversion rate optimisation, often referred to as CRO, aims to improve the percentage of website traffic that converts.

This typically involves a comprehensive research phase to identify areas for improvement and to help generate hypotheses for your website. These hypotheses are then validated through methods such as A/B tests and user testing, and site changes which demonstrate a positive impact on conversions are rolled out permanently.

A successful CRO strategy should involve ongoing tests and website optimisations, ensuring that you maximise the revenue and profit brought in by your site traffic.

What is the difference between SEO and CRO?

While SEO (search engine optimisation) focuses on increasing your organic traffic across search engines such as Google, CRO looks to boost the percentage of traffic which converts. In this way, SEO and CRO actually compliment each other greatly, working hand-in-hand to enhance your organic sales.

It’s worth noting that CRO processes will look to increase conversions across traffic coming from all channels, not just organic. If a particular channel is underperforming, this is something we can identify and investigate further if needed.

Will CRO testing impact my organic rankings?

Our approach to CRO means that any testing will not negatively impact your organic rankings or traffic. A/B and multivariate tests run on the same URL so there are no duplicate content issues to worry about.

If anything, implementing an effective CRO strategy can actually lead to improvements in your organic performance, as continuous testing and optimisations should lead to improvements in your website’s overall content and usability – both of which are key to SEO success.

When tests are not conducted correctly, this can lead to problems, which is why working with an experienced CRO partner is advantageous. We can guide you through the process of setting up and running tests, or implement them ourselves depending on the level of support required.

Will the testing software slow down my website?

When it comes to implementing any testing software on your website, it’s essential to consider the potential impact on site performance. Fortunately, we’ve taken great care in selecting tools that strike a delicate balance between enhancing your website’s conversion potential and minimising any adverse effects on its speed. For example, VWO uses lightweight, asynchronous code which loads seamlessly and in parallel with your website, ensuring there is no noticeable impact on load times. Rest assured, you can confidently integrate VWO on your site while know that your visitors will continue to enjoy a fast and responsive browsing experience.

How much website traffic do we need?

We cater to businesses of all sizes, which means we work with websites with all levels of traffic.

If your website does have very low levels of traffic (e.g. less than 5,000 sessions per month), we will discuss the best approach and tailor your strategy to ensure you still get maximum value. In some cases, it may make more sense to explore our SEO services initially, in order to grow your traffic before visiting CRO at a later date.

Can we just do user testing (or another service), instead of one of your full CRO packages?
