What is CRO?
WebAnts is a conversion rate optimisation agency in London — turning the traffic you already have into more leads and more sales.
Most businesses respond to disappointing lead volumes by increasing their ad budget. CRO is the alternative: fix the conversion rate first. A site converting at 1% that doubles its ad budget generates 2× the leads at 2× the cost. A site converting at 2% generates the same result from the same traffic — at zero extra ad spend. That is the CRO value proposition.
WebAnts applies a structured methodology: audit first (identify the conversion blockers), prioritise by impact, implement the highest-leverage fixes, and measure the result. Every engagement ends with a before-and-after comparison so you know exactly what the investment was worth in revenue terms.
(How we work)
Four phases.
Zero guesswork.
Audit first. Analyse the data. Implement the fixes. Measure the result. Every WebAnts CRO engagement follows the same four-phase methodology — with before-and-after conversion reporting on every project.

(CRO services)
Eight conversion optimisation services, all delivered by the same London team.
Audit first, implement second, measure always.
CRO Audit
Full website audit identifying conversion blockers: page hierarchy issues, CTA placement, form friction, load speed problems, mobile UX failures, and trust signal gaps. Delivered as an annotated Figma document with prioritised fixes across your top five traffic pages and primary conversion path.
Heatmap & Session Recording Analysis
Hotjar or Microsoft Clarity installation and analysis — identifying exactly where visitors drop off, what they click, and what they ignore. We deliver a behaviour report with annotated screenshots and prioritised findings. Session recordings reveal patterns analytics dashboards obscure.
Landing Page Redesign
Full landing page redesign based on audit findings: above-the-fold hierarchy, benefit-led copy, social proof placement, form optimisation, and CTA copy and colour testing. Designed in Figma, approved by you, then built with conversion data embedded in every decision.
A/B Testing Setup
VWO or Optimizely A/B test setup for headline copy, CTA copy, form length, social proof placement, and page layouts. We define the hypothesis, set up the test, confirm statistical significance thresholds, and report results in plain English with revenue-impact calculations.
Form Optimisation
Multi-step vs single-step analysis, field reduction, label copy, error message UX, and mobile keyboard type optimisation. Removing one unnecessary field typically increases form conversion by 20–30%. We audit every form on your key pages and deliver rewritten, restructured alternatives.
Checkout & Ecommerce CRO
Shopify checkout abandonment analysis, product page optimisation, cart page redesign, trust badge placement, and upsell positioning. WebAnts specialises in Shopify and WooCommerce — checkout CRO follows a different methodology to lead-gen sites, and we apply the right approach to each.
Copy & Messaging Audit
Review of headline, sub-headline, benefit copy, social proof, and CTA copy on every key page — with rewritten alternatives tested against originals. Most websites fail on messaging before they fail on design. We audit the copy hierarchy and deliver rewritten versions grounded in what your best customers respond to.
CRO-First Redesign
For sites where incremental fixes are not enough — a full redesign with CRO baked in from wireframe stage. Every design decision is justified by conversion data, not aesthetics. We start with an audit, map conversion blockers, then design a new site that fixes them structurally.
(The CRO argument)
Why CRO before
more ad spend?
The maths are undeniable
Double your ad budget and get twice the leads at twice the cost. Fix your conversion rate and get the same uplift from the same traffic — at zero extra spend. CRO is a multiplier on every pound you spend acquiring visitors, regardless of the source.
Every traffic channel benefits
CRO improvements apply to organic search, paid ads, email, social, and direct traffic equally. A landing page converting at 2% instead of 1% doubles the return on every pound spent driving traffic to it — and you do the CRO work once.
Ad costs only increase
Average cost-per-click in competitive Google Ads categories rises 15–20% year on year. Fixing your conversion rate is a hedge against rising acquisition costs. A business converting at 3% can profitably outbid competitors converting at 1% — and still win more leads at lower cost.
The fix is often simpler than expected
In most audits, the highest-leverage fixes are not complex redesigns. They are a form three fields too long, a CTA that does not appear above the fold on mobile, or a headline that describes the service rather than the outcome. These fixes take days, not months.
CRO compounds over time
Each improvement to conversion rate is permanent. Unlike ad spend that stops producing leads the moment you stop paying, a CRO improvement continues delivering better results for every visitor indefinitely. Each subsequent improvement compounds on the improved baseline.
The audit pays for itself immediately
A £1,500 CRO audit on a site receiving 3,000 visitors per month at 1% conversion (30 leads) that moves to 1.5% (45 leads) adds 15 leads per month. At an average lead value of £200, that is £3,000/month in additional pipeline — the audit pays back twice over in month one.

(FAQ)
Common questions about CRO.
Every question, answered directly. Still unsure? Email us at hello@webants.io.
What is conversion rate optimisation (CRO)?
Conversion rate optimisation (CRO) is the process of improving a website so a higher percentage of its visitors take the action you want — submitting an enquiry form, purchasing a product, booking a call, or signing up for a service. CRO works by identifying the specific reasons visitors are not converting — slow load speed, unclear CTAs, form friction, missing trust signals, confusing navigation — and fixing them through redesign, copy changes, and A/B testing. Unlike paid advertising, which increases traffic, CRO improves what you do with the traffic you already have. A site converting at 2% instead of 1% doubles your leads without spending an extra pound on ads.
How much does CRO cost in London?
CRO costs in London vary depending on the scope of work. A CRO audit from WebAnts starts from £1,500 and takes 1–2 weeks — this covers a full annotated audit with prioritised fixes. A CRO Sprint (audit plus implementation) starts from £3,000 and takes 3–4 weeks. A full CRO programme including checkout optimisation, A/B testing, and a monthly retainer starts from £5,000 and runs 6–8 weeks. WebAnts provides flat written quotes after a free 30-minute discovery call — no hourly estimates. No prepayment required.
What is a good conversion rate for a website?
Average website conversion rates vary by industry. For B2B professional services, 2–5% lead conversion is good. For ecommerce, the industry average is 1.5–3%, with top stores at 5–8%. SaaS free trial pages typically convert at 5–15% for warm traffic. If your site converts below 1% from organic search, there are almost certainly structural issues with CTA hierarchy, form friction, or trust signals. WebAnts typically achieves a 2–5× uplift in conversion rate from a CRO audit and sprint engagement.
How long does CRO take to show results?
A CRO audit is delivered in 1–2 weeks and immediately reveals what is blocking conversions. Implementation of fixes (landing page redesign, form optimisation, copy rewrite) takes a further 2–4 weeks in a CRO Sprint. A/B tests typically need 2–4 weeks to reach statistical significance depending on traffic volume. For sites with very low traffic, we recommend implementing fixes directly rather than A/B testing. We give you honest advice on which approach is right for your traffic level.
What is A/B testing and how does it work?
A/B testing (split testing) compares two versions of a page to determine which converts better. Version A (original) is shown to 50% of visitors and Version B (changed version) to the other 50%. After enough visitors see both to achieve statistical significance — typically 95% confidence — you can declare a winner. Common A/B tests include headline copy variants, CTA button copy and colour, form length, social proof placement, and page layout. WebAnts sets up A/B tests using VWO or Optimizely, defines statistical significance thresholds upfront, and reports results in plain English with revenue-impact calculations.
What are the most common conversion killers on a website?
The most common conversion killers in CRO audits: (1) Slow page load speed — every second of delay reduces conversions by approximately 7%. (2) Unclear or buried CTAs — if visitors cannot see what to do next within three seconds, they leave. (3) Forms that are too long — removing one unnecessary field typically increases form conversion by 20–30%. (4) Missing social proof — testimonials, ratings, and client logos near CTAs significantly increase trust. (5) Mobile UX failures — over 60% of traffic is mobile and most sites have significant mobile conversion issues. (6) Headline copy that describes the service rather than the outcome. (7) No urgency or specificity — vague CTAs like 'Learn more' convert far less than specific ones like 'Get a free audit'.
Can CRO help my Shopify or ecommerce store?
Yes — ecommerce CRO is one of the highest-ROI forms available. WebAnts specialises in Shopify and WooCommerce checkout optimisation, product page redesign, cart abandonment reduction, and trust signal placement. The most common ecommerce fixes: checkout form simplification, trust badge placement near the payment button, product page copy restructuring (benefits before specifications), free shipping threshold visibility, and social proof on product pages. A WebAnts ecommerce CRO sprint starts from £3,000 and typically achieves a 15–35% improvement in checkout completion rate.
Do I need a CRO agency or can I do it myself?
You can implement basic CRO yourself — installing Hotjar, reviewing heatmaps, and making copy changes is accessible without an agency. However, a CRO agency adds: (1) Pattern recognition across many sites — we have seen hundreds of conversion blockers across industries and know what a 0.8% conversion rate usually means before looking at a single heatmap. (2) Objective analysis — internal teams are too close to their own sites to see what first-time visitors see. (3) Implementation speed — a CRO Sprint with WebAnts delivers a full audit, landing page redesign, and A/B test setup in 3–4 weeks. The same work internally typically takes 3–4 months. For businesses spending £5,000/month or more on paid traffic, a CRO audit typically pays for itself in the first month.
What tools do you use for CRO?
WebAnts uses: Hotjar or Microsoft Clarity for heatmaps and session recordings; VWO or Optimizely for A/B testing; Google Analytics 4 for conversion funnel analysis; Google Search Console for landing page performance data; PageSpeed Insights and Core Web Vitals for load speed analysis; Figma for annotated audit reports and redesign mockups. For ecommerce clients, we also use Shopify Analytics, WooCommerce reporting, and cart abandonment data from Klaviyo or Mailchimp. We choose tools based on what you already have installed where possible.
How do you measure conversion rate improvement?
We establish a baseline before any changes and compare the same metric after a defined post-implementation period. For lead generation sites, the primary metric is form submission conversion rate (unique visitors divided by form submissions). For ecommerce, the primary metric is checkout completion rate. We also track micro-conversions — scroll depth, button clicks, time on page. All before-and-after data is included in the delivery report with revenue-impact calculations so you know exactly what the improvement was worth in monetary terms.
What is the difference between CRO and SEO?
SEO increases the number of visitors from Google and other search engines. CRO increases the percentage of those visitors who take the action you want once they arrive. They are complementary disciplines. A site with excellent SEO but poor CRO is driving expensive traffic to a leaking bucket. A site with excellent CRO but poor SEO has a high-converting page that very few people ever see. At WebAnts, we apply CRO principles to every site we build as standard — regardless of whether the project is a dedicated CRO engagement or a new website build.
