Conversion audit or conversion programme: which do you need?
Buy an audit when you need to know what is wrong and you have the capacity to fix it yourself. Buy a programme when you know roughly what is wrong and you need someone to run the fixing for six months. Buying an audit and then not acting on it is the most common waste of money in this category.
What an audit actually gets you
A ranked list of specific, evidenced problems with an estimated value attached to each, plus test briefs for the top five. Four to six weeks, fixed scope, fixed price.
It is the right purchase in three situations. You have an internal team who can execute but not diagnose. You are deciding whether conversion work is worth committing to and want evidence before signing a longer engagement. Or you are inheriting a site and need a map before you touch anything.
The failure mode is entirely predictable. The audit lands, everyone agrees it is excellent, and then it sits in a Drive folder because the internal capacity that was supposed to execute it was already fully committed. If you cannot name the person who will implement the roadmap and the hours they have free, an audit is a very well-researched document you will not use.
What a programme gets you
The diagnosis plus the execution plus the loop that connects them. Research feeds hypotheses, hypotheses become tests, results re-rank the roadmap, and the cycle repeats.
The loop is the actual product. Any individual test is likely to fail: Optimizely’s analysis of more than 127,000 experiments puts the average win rate near 12%, and ConversionTeam’s audit of 2,288 tests found 19.1% reached significance per test. You are not buying a test. You are buying enough attempts, sequenced well enough, to reach the ones that work.
That is why duration matters more than intensity. Research from Harvard Business School cited in industry analysis found companies adopting systematic A/B testing see performance improvements of 30% to 100% within a year, with the highest testing velocity compounding fastest.
Side by side
| Audit | Programme | |
|---|---|---|
| Duration | 4 to 6 weeks | 6 months minimum, realistically |
| You get | Diagnosis, roadmap, test briefs | All that plus execution and iteration |
| You supply | Data access, then execution capacity | Data access, one decision-maker, two hours a week |
| Fails when | Nobody implements it | Nobody can approve a change |
| Right if | You can execute but not diagnose | You need both, sustained |
| Wrong if | You have no build capacity | You have under 1,000 monthly conversions |
The traffic question that decides it for you
Below roughly a thousand conversions a month, a programme struggles. The effects being hunted are small, winners in DRIP’s data produced a median 1.88% conversion lift, and the median test ran 42 days. Six months at that volume produces a handful of readable results.
At low volume the audit is the better purchase, followed by shipping the structural fixes whole rather than testing them incrementally. Come back to a programme when the traffic supports it.
The hybrid worth considering
Audit first, on a fixed scope, with an agreed option to convert into a programme at the end of it.
This solves the two failure modes simultaneously. You get evidence before committing to six months, and the agency has a reason to write an implementable roadmap rather than an impressive one, because they may be the ones implementing it. It also gives both sides a clean, unembarrassing exit if the diagnosis reveals the problem is positioning rather than conversion.
Ask for that structure explicitly. Most firms will agree to it and very few offer it unprompted.
One more consideration on timing. An audit commissioned in October is an audit read in December, when nobody is shipping and peak season has frozen the site. Commission diagnostic work in a quiet quarter and execution work ahead of a busy one, rather than the other way round.
What to check before you buy either one
Ask what data access is required, and treat any firm willing to proceed without analytics access as unserious. Ask how many findings will come with test briefs attached, because findings without briefs are opinions. And ask what happens if the conclusion is that your funnel is basically fine, then listen to whether the answer is specific.
Parah Group runs the audit as the first month of the programme rather than as a separate product, which is one way of solving the implementation gap.
