You are generating traffic on your site, but the sales are not following? On average, only 2.35% of a website's visitors take the action the owner wants. That means 97.65% of your traffic leaves without converting. Optimising your conversion funnel is the most profitable strategy there is: you sell more without spending more on advertising.
At ConvertiLab, we optimise the conversion funnels of our 150+ clients. The best results have come from working on the landing page, A/B testing the CTAs, and removing the friction in the buying journey.

What is a conversion funnel and what are its key stages?
A conversion funnel is the journey a visitor follows from their first interaction with your brand through to the purchase. It breaks down into 3 levels: TOFU (top of the funnel, acquiring qualified visitors), MOFU (middle of the funnel, engagement and consideration), and BOFU (bottom of the funnel, decision and conversion). Each level naturally loses visitors. The goal of CRO (Conversion Rate Optimisation) is to minimise those losses at every stage.
The modern digital funnel with its key metrics:
| Stage | Main channel | Objective | Target metric |
|---|---|---|---|
| Discovery (TOFU) | SEO, Ads, Social | Attract qualified traffic | Impressions, clicks |
| Consideration (MOFU) | Blog, Landing page | Educate and engage | Time on page, leads |
| Decision (BOFU) | Service page, testimonials | Convince | Enquiries, baskets started |
| Conversion | Checkout, form | Sell | Conversion rate |
| Retention | Email, support | Retain and resell | LTV, retention rate |
How do you analyse your current funnel and find the leaks?
To analyse your conversion funnel, the 3 essential tools are: Google Analytics 4 (user journeys, bounce rate, exit pages, free), Hotjar or Microsoft Clarity (heatmaps, session recordings, freemium), and Google Search Console (entry page performance). The central question is this: where do visitors leave the site? The page with the highest bounce rate is your number 1 priority. Microsoft Clarity is particularly good for beginners because it is entirely free and offers unlimited session recordings, so you can watch exactly what your visitors do in real time.
The questions to ask when you diagnose your funnel:
How do you optimise a landing page to double your conversion rate?
A landing page built for conversion needs: a strong headline carrying the main benefit (not the name of your service), a subheading that expands the promise, social proof (testimonials, client logos, numbers), a simple form (3 fields maximum), a visible and actionable CTA, and zero distraction (no navigation menu). At ConvertiLab, our landing pages reach an average conversion rate of 8 to 15%, against 2 to 3% for a standard home page.
Conversion techniques at the bottom of the funnel (BOFU):
Remove the friction, because every friction is a lost client:
ConvertiLab case study: an electrician in the Île-de-France region was getting 1,200 visitors a month on his site with only 4 quote requests. After a Hotjar analysis, we found that 78% of mobile visitors left the page before reaching the form, which sat right at the bottom. Once the form moved to the top of the page, shrank to 3 fields (name, phone, postcode) and gained a "Reply within 2 hours" badge, enquiries went from 4 to 19 a month, with no increase in the advertising budget.

How do you set up A/B testing to improve your conversion rate?
A/B testing means comparing two versions of a page to see which one converts better. The 5 elements to test first are: page headlines (the number 1 conversion lever), CTAs (wording, colour, position, size), images (a person vs a product, a photo vs an illustration), forms (number of fields, layout), and social proof (where the testimonials sit and in what format). The fundamental rule: test one variable at a time, with at least 1,000 visitors per variant over 2 to 4 weeks.
CTA wording is one of the easiest and highest impact changes: "Send" converts 3 times less well than "Get my free quote". Using the first person possessive ("my") and spelling out the value received lifts the click rate every time. Examples that perform: "Get my free analysis", "Book my place", "Download my checklist".
The 3 most common CRO mistakes that wreck A/B tests:
Benchmark conversion rates by sector:
| Sector | Average rate | Target |
|---|---|---|
| E-commerce | 2 to 3% | > 4% |
| SaaS | 3 to 5% | > 7% |
| B2B services | 2 to 4% | > 5% |
| Lead generation | 5 to 10% | > 12% |
| Dedicated landing page | 5 to 15% | > 20% |
Frequently asked questions about conversion funnel optimisation
What counts as a good conversion rate?
It depends on your sector and your objective. In e-commerce, 2 to 3% is the average. For a lead generation landing page, 10 to 15% is a good target. What matters is improving it constantly rather than chasing an absolute figure. The benchmark that counts: your own data over the last 3 to 6 months. A good sign of progress: if your conversion rate rises by 10 to 20% from one quarter to the next, your CRO strategy is on the right track.
How long does it take to optimise a conversion funnel?
Optimisation is a continuous process. You can see significant results in 1 to 3 months with regular A/B tests. The quick wins (a shorter form, a better CTA) can be measured in 2 weeks. Deeper work (a landing page rebuild, an email funnel) takes 1 to 3 months to gather enough reliable data.
Is CRO worth it with little traffic?
Yes, because doubling your conversion rate is the same as doubling your traffic at no extra cost. With 500 visitors a month at a 2% conversion rate = 10 clients. At 4% = 20 clients. The same impact as buying 500 extra visitors through advertising. With little traffic, focus on the changes with the most impact: a simplified form, a clear CTA, visible social proof.
How do you know whether an optimisation really worked?
Always measure like for like: the week before against the week after. For the results to be reliable, wait until you have at least 100 conversions on each variant, below that threshold statistical noise can hide the real impact. Use Google Optimize (free) or VWO for your A/B tests, these tools handle statistical significance automatically and alert you when the results are solid. !CRO A/B testing statistics significance test reliable results
