Landing Page Audits for Agencies: Audit Client Pages in Minutes, Deliver Fixes

The audit is how agencies win the retainer

Nothing sells a CRO engagement like showing the prospect something specific and true about their own page before they have paid you anything. Generic capability decks get skimmed. A scored audit of their highest-traffic landing page, with three named defects and the rewritten headline sitting next to the current one, gets a second meeting.

The problem has always been cost. Done by hand, a decent landing page audit takes a senior person two to four hours: pull the analytics, walk the page on mobile and desktop, check load behavior, count the form fields, read it as a stranger, and then write it all up presentably. At any realistic hourly rate that is a couple of hundred dollars of unbilled time per prospect, which is why most agencies only audit after the contract is signed, and why they lose deals they could have won.

What belongs in a landing page audit deliverable

The last row is the one most agencies skip and the one that converts best. Saying plainly that you cannot see their conversion data yet, and that these are data-informed recommendations rather than guaranteed lifts, reads as expertise rather than hedging. Overpromising a percentage you cannot support is the fastest way to lose a sophisticated buyer.

Pricing an audit as a paid deliverable

There are three models that work, and the right one depends on where the audit sits in your funnel. As a free lead magnet, the audit has to cost you close to nothing to produce, which is only true if it is tooled rather than hand-built. As a paid standalone, agencies commonly charge somewhere between a few hundred and a few thousand dollars depending on scope and seniority, and it functions as a paid trial that de-risks the retainer for both sides. As a bundled first deliverable inside a retainer, it justifies the first month before any test has had time to read.

The economics only work in the first model if the marginal cost per audit is low. That is the actual reason to tool this: it is not that software audits better than a good strategist, it is that it lets a good strategist audit forty prospects instead of four. Our breakdown of what CRO costs across tools, agencies, and in-house work covers how clients tend to price-anchor on this.

Auditing a client page without any access

You do not need analytics access, admin credentials, or a tracking snippet to audit the things that are wrong with most landing pages. Copy quality, offer clarity, CTA competition, form length, trust signals, information order, and load behavior are all observable from the public URL. That is what makes pre-sale auditing possible at all.

What you genuinely cannot see without access is the conversion rate itself, the traffic mix, where in the funnel people drop, and whether a change helped. So the honest structure is: audit what is visible before the sale, and make analytics access the first thing you ask for after it. Say so in the deliverable. Clients notice the distinction and it builds trust.

How agencies run this with Converto

Paste the client URL. Converto audits copy, layout, CTAs, page speed, and AI-readability, returns a 0 to 100 score with the components broken out, ranks the defects, and generates the rewritten headline, CTA, and form copy. It runs fast enough to do live on a discovery call, which changes the dynamic of that call considerably. Nothing is installed on the client site and no permissions are needed, so there is no procurement conversation before you can start.

The landing page audit feature page details what each check covers, and CRO agency versus CRO tool is worth reading if clients raise it. Suggestions are data-informed, not guarantees.
