Conversion work is sold as testing and is usually bought by sites that cannot test. A split test needs enough conversions in each variant to distinguish a real difference from noise, and for most businesses that means months per test, by which time the answer has stopped being useful. The first honest question any supplier should ask is how many conversions a month you get, and the answer decides which of two very different services you should be buying.
Ask about your conversion volume before anything else
With a few hundred conversions a month, a formal testing programme is reasonable and will find real improvements. With a few dozen, it cannot resolve anything smaller than a very large change, and running tests anyway produces confident conclusions from noise, which is worse than not testing. A supplier who quotes a testing retainer without establishing your volume is selling a process rather than an outcome.
Below that threshold, buy judgement instead
For lower-volume sites the productive work is expert review, session recordings, actually watching people use the thing, talking to customers who nearly bought, and fixing what is plainly broken. Those find the large problems, which at low volume are the only ones worth fixing. It is less impressive on a slide and it is the honest service for most businesses that ask about conversion rates.
Most conversion problems are not on the page
Wrong traffic, an unclear offer, a price the market will not pay, a form asking for information the buyer will not give yet, a follow-up that takes two days. Button colours and headlines are the visible end of a chain that usually breaks earlier. A supplier who starts by asking who is arriving and what they expected is going to find more than one who starts by redesigning the page.
Decide what counts as a conversion, and be strict
Optimising towards a soft action, a download, a newsletter sign-up, a short call, produces more of that action and sometimes fewer customers. Define the outcome you actually want, measure it, and accept the smaller number. This is the single most common way a conversion programme reports success while revenue does not move, and it is settled in the first week or not at all.
A test that loses is a result, and the programme should say so
A credible programme publishes its losers and its inconclusive tests along with its wins, because the proportion tells you whether the hypotheses are any good. A report showing an unbroken run of improvements is describing either a very unusual site or a measurement that is not being applied honestly. Ask for the full record, including the tests that were stopped early and why.
Questions people ask about conversion rate services
How much traffic do you need to run conversion tests?
Enough conversions, not enough visitors. A few hundred conversions a month makes a testing programme viable; a few dozen does not, and at that level expert review and customer conversations find more than tests can resolve.
Is conversion work cheaper than buying more traffic?
Often, because an improvement applies to all future traffic rather than being rented. That is only true if the improvement is real, which is why the volume question decides whether you can tell.
What should a first engagement deliver?
A ranked list of the things most likely to be costing you customers, with the reasoning, plus whatever is plainly broken fixed. A testing roadmap is the right deliverable only if your volume supports testing.
Should the agency define our conversion?
They should challenge it; you should own it. If the agreed conversion is a soft action, the programme will optimise towards it faithfully and may deliver more of it while revenue stays flat.
