More traffic is not always the next thing your website needs. If people are already arriving and leaving without enquiring or buying, paying to send more of them through the same journey can make the problem more expensive.
Conversion rate optimisation means improving the proportion of visitors who take a useful action. That could be a completed order, a qualified enquiry or a booked appointment. The useful part matters: a button click is not automatically a customer.
How conversion rate optimisation is measured
Choose a goal and a denominator before comparing numbers. A session-based conversion rate is the number of sessions containing the chosen action, divided by total sessions, multiplied by 100. If 20 of 1,000 sessions include a completed enquiry, the rate is 2%.
Google Analytics defines session key event rate around sessions containing a key event. A report covering any key event can include actions other than the sale or enquiry you actually care about. Use the relevant event, and do not divide raw event counts by sessions and assume it is the same measure.
For a service business, keep a second measure outside the website: how many enquiries become worthwhile jobs? For an online shop, look at revenue and contribution per session alongside the purchase rate. Discounting everything can raise conversion while reducing profit.
Check the measurement before changing the page
Submit a test enquiry on a phone. Confirm it arrives in the right inbox and is recorded once, after successful submission. A form-start event or a click on the submit button can fire even when the person never finishes.
For ecommerce, check a test purchase through the platform's supported testing process. Verify the order value, currency and transaction identifier. Make sure refreshing the confirmation page does not create a second reported sale.
Analytics will not capture every visitor. Consent choices, browsers and attribution rules create gaps. Use it to understand patterns, and check reported outcomes against actual orders and enquiries rather than treating one dashboard as the complete truth.
Start with the page closest to the money
Pick an important landing page with meaningful traffic and a clear goal. Review the journey from the advert or search result through to completion. Does the page deliver what the visitor was promised? Can they tell who it is for, what it costs or what happens next?
A Cork electrician's page needs to make the service area and contact route obvious. A national retailer needs clear delivery charges, product information and returns details. Neither benefits from hiding those answers beneath a long introduction about being passionate.
- Clarity: state the service or product in language a customer would use.
- Evidence: place relevant work, genuine reviews or product demonstrations beside the decision.
- Friction: remove unnecessary form fields and explain errors clearly.
- Confidence: show availability, delivery information and a credible contact route.
- Usability: check the page on a small screen, with keyboard navigation and readable text.
Irish details that can change the decision
If you sell across Ireland, name the areas you cover and make exceptions clear. Show euro pricing where that is the price you charge. Explain delivery to the Republic and Northern Ireland separately if the terms differ. Do not leave customers guessing whether you ship from Ireland or from somewhere else.
For local services, say how appointments work and what information you need for a quote. A short form asking for the job and location may be enough to start. Asking for a full postal address, budget, company size and five other details before answering a basic question can discourage a suitable enquiry.
Use evidence to choose the first change
Combine page data with what customers actually tell you. Read enquiry emails, ask the person answering the phone what comes up repeatedly, and watch a few people try to complete the task. You may discover a missing answer that no colour change will fix.
Write a simple hypothesis: “People leave the product page because delivery costs are unclear. Showing the charge and expected dispatch timing beside the buy button should reduce that uncertainty.” That gives the change a purpose and tells you what to inspect afterwards.
Illustrative maths: at 2,000 sessions a month, moving from 2% to 2.5% means 10 additional converting sessions, assuming the same traffic. That is a 0.5 percentage-point increase, or a 25% relative uplift. It is an example, not a promised result.
When is an A/B test worth running?
A proper A/B test randomly divides comparable traffic between versions. Decide the main measure, the effect worth detecting and the sample needed before starting. Check that assignment and tracking work, and give the test enough time to include normal business patterns.
A small site with a handful of enquiries a month may not have enough traffic to detect a modest difference in a practical timeframe. Fix obvious faults, use customer research and monitor the result, but be honest about what the evidence proves.
A before-and-after comparison can be affected by a promotion, seasonality or a change in ad targeting. Do not credit the redesign with every increase simply because it happened first.
Optimisation or a full redesign?
If the structure works and one form or product page is weak, improve that part. If navigation, mobile usability and content organisation all get in the way, website redesign services may be the more sensible scope.
For Shopify, begin with the store fixes worth making before more ad spend. For a service site, the article on why a website is not getting customers covers the common starting points.

I've spent the last four years working with owner-led businesses in Cork and across Ireland — first in-house at a fast-growing Irish ecommerce brand, then agency-side running teams, and now independently. I write about what I actually see in client accounts, not what's fashionable this quarter.
