Baselines before promises
We won't quote a lift until we've seen 12 months of your data. Any agency that forecasts your growth before reading your analytics is quoting their average, not your store.
ConversionEX is a Shopify and Klaviyo growth agency. We have been building and optimising online stores since 2012 — first on WordPress and WooCommerce, now exclusively on Shopify — and we run the conversion, retention and acquisition programs that make them worth more every quarter.
We started in 2012 building WordPress sites, then WooCommerce stores, with a conversion practice attached because clients kept asking the same question a month after launch: it's live, so why isn't it selling? That question turned out to be the entire business. The name is not a metaphor — conversion was the service before it was the brand.
We shipped WooCommerce for the better part of a decade, so we know exactly what it costs. The plugin stack that breaks on a Tuesday update. The checkout you can extend right up until it collapses. The hosting invoice that arrives the month a campaign finally works. We were spending more of every retainer keeping stores upright than making them sell, so we moved — our own builds first, then our clients — to Shopify, and rebuilt the growth side around Klaviyo. Today it's 140 builds and migrations shipped, 38 active stores, and roughly $410M in annual GMV running through accounts we're responsible for.
That history is why replatforming is the service we are hardest to beat on. We are not moving you off a platform we have only read about — we built on it for years. We know which of your plugins has no Shopify equivalent and will have to become custom work, which of your URLs are quietly carrying your organic revenue, and which parts of your data are dirtier than your team thinks they are.
The other half of the job is the audience you already own. Paid traffic gets more expensive every year, so the stores that compound are the ones turning first orders into second and third ones. We build that inside Klaviyo — flows, segmentation, RFM-based lifecycle work and the reporting that shows what share of revenue is coming from channels you don't rent — and we hold it to the same standard as everything else: measured in Shopify, not in the platform's own dashboard.
The philosophy is boring and it works: decide what the number is, instrument it properly, then change one thing at a time. Most agency reporting is a performance — a deck of upward arrows detached from the merchant's actual P&L. Ours starts with the money that hit your Shopify payouts, works backwards to the channels, and shows the work that failed alongside the work that didn't. If we can't attribute it, we don't claim it.
Who we say no to: pre-launch brands with no traffic to test against, anyone under roughly 40,000 monthly sessions, new WordPress and WooCommerce builds — we spent years shipping them, which is precisely why we don't any more — and merchants who want us to guarantee a ROAS number we don't control. We also turn down work when the honest answer is that the store doesn't need an agency yet — three fixes and six months of selling will do more than a retainer will. Saying that out loud has cost us deals and won us more.
These are not values on a wall. They are the reasons we have turned work down.
We won't quote a lift until we've seen 12 months of your data. Any agency that forecasts your growth before reading your analytics is quoting their average, not your store.
Each engagement gets a single primary metric — CVR, AOV, MER, retention rate. Everything else is diagnostic. Teams optimizing four metrics at once optimize none of them.
Nothing stays live because someone senior liked it. Features, flows and campaigns get a review date at launch, and the ones that don't pay get removed instead of accumulating.
Every dashboard, ad account, theme repo and Klaviyo instance is created under your ownership from day one. If you leave, you leave with everything, and we'll do the handover call.
Nobody signs a retainer with us before we've both seen the data. The audit is paid, fixed-fee and fully credited against the first three months of any engagement that follows.
We pull 12 months of Shopify, GA4, Klaviyo and ad-platform data, then run a technical, heuristic and session-replay pass across the store. Findings come back ranked by projected revenue impact, not by severity score.
The backlog becomes a fixed-price scope with a delivery date and a named team. We forecast the outcome in dollars and write down the assumptions, so you can hold us to both.
Design and engineering run in one track, wireframed from the checkout backwards. Migrations carry a redirect map and analytics parity check that has to pass before we schedule cutover.
We rebuild tracking across GA4, Shopify, Klaviyo and server-side CAPI so the numbers agree with each other before we test against them. Then experiments go live on a steady cadence, each with a hypothesis and a stopping rule written before launch.
CRO, Klaviyo email and SMS, SEO, Google Ads and Meta Ads run against one blended MER target instead of five competing dashboards. Quarterly we re-forecast and cut whatever stopped paying.
