Start the buying decision with account evidence, not projected lead volume. The proposal should connect call or form enquiry with need, location or company fit, and contact details verified, sales-accepted appointment or opportunity, and closed service engagement.

Our bias is clear because we provide this service. Even so, the buyer should retain account custody, source records, and enough detail to challenge every recommendation after the engagement ends.

## An audit should end with decisions and evidence

Reject an audit that exports platform recommendations and stops. The deliverable should connect each finding to an account location, a dated data window, the affected funnel stage, an owner, and the next decision. [Google Ads search terms report documentation](https://support.google.com/google-ads/answer/2472708?hl=en) defines platform evidence that the auditor can inspect.

The prioritization method should separate measurement faults, wasted demand, conversion friction, and scaling constraints. Fix broken attribution before changing bids, because a bidding recommendation built on false conversions is not yet a recommendation.

A useful audit also records uncertainty. If low volume prevents a confident verdict, we want the missing evidence and a plain test plan, not a confident-looking score.

## The sales record sets the buying unit

Use four stages in the operating record: call or form enquiry, need, location or company fit, and contact details verified, sales-accepted appointment or opportunity, and closed service engagement. Owners, timestamps, identifiers, and rejection reasons make each handoff auditable.

Google defines the search terms report as the record of searches that triggered ad impressions and clicks. See the [Google Ads search terms report documentation](https://support.google.com/google-ads/answer/2472708?hl=en). The documented control explains what the platform can do. It does not define commercial success for this business.

Keep spam, duplicate, job seeker, vendor, or low-fit enquiry separate from a qualified lead that did not close. Those cases point to different faults: targeting or routing in the first; offer, timing, or sales execution in the second.

## Put account ownership in writing

Google supports hashed first-party lead data and CRM outcome imports to connect later lead stages with earlier ad interactions. See the [Google enhanced conversions for leads documentation](https://support.google.com/google-ads/answer/15713840?hl=en). In practice, the scope must explain how the operator inspects that control and what happens after the review. For Microsoft Advertising, inspect imported settings, keywords, search terms, network distribution, negative keywords, responsive ads, Universal Event Tracking, conversion goals, and CRM outcomes. A Google Import is a starting copy that still needs checking against Microsoft traffic and need, location or company fit, and contact details verified.

The deliverables should include access, conversion checks, lead-rejection rules, CRM reconciliation, and a dated decision log. Any excluded creative or page work needs an owner and a schedule dependency.

The forecast should use the client's own geography, offer, capacity, close rate, and qualification policy. Platform averages cannot replace those inputs.

## A platform average cannot set this budget

A spending limit can be tested with four declared assumptions. For illustration, use $25,289 in collected first-year revenue per closed service engagement, 50% gross margin, 25% conversion from need, location or company fit, and contact details verified, and a 65% acquisition allowance against expected gross profit.

The result is $2,055 per qualified lead: $25,289 × 50% × 25% × 65%. It is a planning example, not a market benchmark. Actual finance and CRM data should replace all four inputs, with a further allowance for overhead, slow collection, refunds, bad debt, and capacity. Update the limit as those inputs change.

## Reconcile the platform with the operating record

The account, analytics property, landing-page history, and CRM export should support the same sequence. When the platform reports a conversion but the sales team records spam, duplicate, job seeker, vendor, or low-fit enquiry, the weekly report needs to show the mismatch and the rule used to resolve it.

Microsoft documents Universal Event Tracking, conversion goals, remarketing audiences, automated bidding, and target CPA. See the [Microsoft Advertising conversion tracking documentation](https://about.ads.microsoft.com/en/tools/performance/conversion-tracking).

These sources are evidence for the platform setup, not a performance promise. Current account access, sales outcomes, and controlled tests are still required.
