If your GA4 and Google Ads numbers don’t match your CRM or your back-end, you will know what it costs: bids set on the wrong number, and a channel judged on data nobody trusts. At £10k a month of paid media, a conversion count that is 20% out is £24k a year of spend decided on the wrong number.
Conversion Uplift is a UK GA4 consultancy led by Neal Cole, author of CXL’s official GA4 and GTM audit course. We find what your GA4 and Google Tag Manager setup is getting wrong, fix it at a fixed price, and keep it right when the site changes. If the tracking keeps breaking, it is usually the data layer rather than the tags, and we fix that too.

A read-only check of your website’s tracking. No account access needed. Neal replies personally, usually within one working day.
Neal Cole wrote the official GA4 and GTM audit course for CXL and has spent 20+ years fixing measurement for Hastings Direct, Casumo, Irish News, Assurant, Gardening Express, The Press Association (PA Media), Marex, Funbox, and other businesses where a wrong number is expensive. He wrote the method. A small team of experienced analysts does the work, and the report tells you what the numbers mean for the decision in front of you.
A childcare brand’s GA4 showed £20,173 of sales in a week. Server-side tracking showed £248,444. Their Google Ads conversion rate was 15.89%, not 0.93%, and they had been about to cut the channel. Read the case study
A Shopify ecommerce brand moved its tracking server-side. No change to ads, targeting or landing pages. Conversion rate rose 11% and acquisition cost fell 11%, worth around £27,000 a month. Read the case study
An online garden shop’s audit found 51% of mobile shoppers leaving at the payment step. Fixing that took it to 19%, worth about £306,000 a month in extra revenue. Read the case study
Setting up GA4 is the easy bit. The work is making sure the numbers are true, keeping them that way when the site changes, and getting them in front of the platforms that spend your money.
A data layer built properly, ecommerce parameters captured accurately, user-provided data for enhanced conversions, data enrichment, and audiences you can actually bid on. Most tracking that keeps breaking is built on the page’s HTML rather than a data layer the developers maintain. Get that right and Google Ads bids on the customers who buy, not the ones who click.
A fixed-price check of your property and container: which events fire, which don’t, duplicate transactions, missing values, consent settings, cross-domain tracking, and whether Google Ads and Meta import the right conversion. You get a prioritised list of fixes and the cost of each gap. What the audit covers.
Client-side tags lose 10% to 15% of conversions to ad blockers, browser extensions and Safari’s tracking prevention. Server-side GTM on Stape recovers them, filters bots, and lets you send profit margin instead of revenue so bidding optimises for the money you keep. Server-side tracking, with prices.
Unsampled GA4 data joined to Search Console, Google Ads, your CRM and your back-end, so reported revenue can be reconciled against invoiced revenue without a £20k to £30k GA360 upgrade. Then continuous checks, so when a release breaks the tracking you find out that day, not at month end when the ad budget is already spent.
Every price is fixed, so if a job takes longer than we estimated, you don’t pay more. That gives you a cost you can plan around, an experienced consultant on the work rather than a junior, and no reason for us to take longer than the job needs.

Most clients start with the £250 audit. If it finds problems, you get a fixed price to fix them, or a written specification your developers can follow. The decision is yours.
What you can’t currently rely on, where the money is, and what a wrong number is costing you. No slides, no pitch.
What’s firing, what isn’t, what it’s worth to fix. Written by the person who will do the work, not a sales team.
Every price we quote is fixed and holds if the work runs over. You put a number in front of your board, and it stays that number.
A GA4 consultant checks that GA4 and Google Tag Manager record what actually happens on your site, fixes what doesn’t, and makes sure GA4 and your ad platforms agree with your back-end. With us that covers GA4 and GTM setup, audits, server-side tagging, BigQuery and ongoing monitoring.
Our GA4 audit is a fixed £250 + VAT, or £450 + VAT with a GTM audit. A Senior Diagnostic starts at £1,500 + VAT. Fixes are quoted at a fixed price once we know what needs doing. Server-side tracking is priced on its own page.
In-house if you have someone who does GA4 and GTM every week; most marketing teams don’t. An agency if tracking is a small part of a wider retainer and nobody needs to own the number. A specialist consultant when the number drives spend and someone has to put their name to it. We also work behind agencies on a white-label basis.
Yes. We audit and fix tracking for agencies’ clients, including on a white-label basis, and we never approach your clients directly.
Not for the free check, which looks only at your public website. For a paid audit we ask for read access to GA4 and GTM.
Yes. We quote a fixed price for the fixes, or give your developers or agency a written specification if you’d rather they do the work.
Mostly. We’re based in Wrexham and most clients are UK businesses spending on paid media. We also work with clients in Ireland and Europe where the time zone makes a weekly call easy.
Yes, and it’s a growing part of the work. AI audit tools find configuration problems quickly and miss what they can’t see: user journeys, consent, cross-domain and whether the numbers match your back-end. The Senior Diagnostic is built for that check.
