Independent review of account management quality, optimization frequency, technical setup, and campaign structure. Based on full Change History export and manual audit findings submitted by the internal team.
Of the 19 months under review, the account recorded zero optimization activity in 7 months: February through May 2025 (four consecutive months), September 2025, December 2025, and January 2026.
For an automotive dealership operating in a competitive local market, this represents a serious management failure. Search trends, competitor bidding, and algorithm behaviour shift continuously. A four-month stretch without intervention means campaigns were left running on outdated settings, likely accumulating wasteful spend on irrelevant queries while performance degraded without correction.
Industry standard: Active accounts should be reviewed weekly, with meaningful changes made at minimum 2–4 times per month. The inactivity pattern observed here falls significantly short of that standard.
The primary conversion goal used for Performance Max optimization is "click on phone number" — not a verified phone call, but a single tap on a phone link. In the US market, this metric is widely considered unreliable because the majority of taps do not result in a connected call.
As a consequence, the Display Network within PMax is recording 97 "conversions" at $1,464 in spend — but these are non-qualifying interactions. Smart Bidding is learning to optimize for low-quality tap events rather than genuine leads, systematically steering budget toward audiences least likely to visit the dealership.
Additionally, ROAS is reporting as zero because the purchase value parameter is not being passed to Google Ads. The algorithm cannot distinguish between a $0 interaction and a $25,000 vehicle inquiry — rendering value-based bidding completely inoperative.
Note: On 6 April 2026, several low-quality local action conversions were removed (menu views, other engagements). This was a step in the right direction, however call tracking was not implemented as a replacement, leaving the conversion foundation still broken.
The account simultaneously runs PMax | New Set and PMax | Local with overlapping geographic targeting and overlapping search query coverage. When two campaigns from the same account bid against each other in the same auction, the result is self-inflicted CPC inflation and inefficient budget allocation.
PMax Local serves its intended purpose well — handling Maps traffic and hyperlocal demand. The problem is that PMax New Set also runs Search, meaning the dealership is competing with itself on identical queries.
Required action: Clearly separate campaign roles — PMax Local for local radius + Maps coverage; PMax New Set exclusively for broader prospecting and new audience development. Alternatively, consolidate into a single campaign with properly segmented asset groups.
Query analysis indicates that approximately 90% of PMax traffic consists of branded or near-branded searches: "mitsubishi harrisburg", "harrisburg mitsubishi", "mitsubishi near me". These represent the highest-value queries in the account — users who have already identified the brand or dealership.
Within Performance Max, there is no direct control over bidding, ad copy, or quality score management for specific queries. Placing these terms in a dedicated Search campaign with Exact/Phrase match would provide granular control and likely improve conversion rates significantly.
Recommended structure: Extract branded + near-branded terms into a separate Search campaign. Allow PMax to focus on genuinely new prospecting audiences.
The account has no dedicated remarketing layer for website visitors who did not convert. In automotive, where the purchase decision cycle spans weeks or months, remarketing typically drives 30–50% of total conversions — making it one of the highest-ROI campaign types available.
The Demand Gen and GDN campaigns present in the account appear to function as broad awareness placements rather than structured remarketing sequences (e.g., inventory page visitors → form abandonment → recent visits). No audience segmentation strategy is evident from the change history.

|---|---|---|---|
| Search | Bad Car Credits | PA | 79 | Most Active | Highest optimization effort. Strong negative keyword hygiene. Paused Apr 2026 — rationale unclear. |
| PMax | Local | 56 | Stable | Well-suited for Maps / local traffic. Budget increased recently. Lowest structural risk. |
| Demand Gen | 18 | Underoptimized | Low change volume relative to channel complexity. No audience segmentation visible. |
| GDN | 16 | Underoptimized | Display without audience layering or remarketing targeting is largely wasted spend. |
| PMax | New Set | 14 | Problematic | Overlaps with PMax Local. Wrong conversion goals. Display generating 97 fake "conversions." |
| Mitsubishi Dealer Near You | 9 | Minimal | Very limited activity. Purpose and structure unclear from available data. |
