The 22 Diagnostic Rules Every Google Ads Account Should Pass

The 22 Diagnostic Rules Every Google Ads Account Should Pass

A typical $5,000-per-month Google Ads account hemorrhages $400 to $600 monthly on avoidable mistakes. Not strategy gaps—basic diagnostic failures. You're paying for clicks to pages that don't convert, bidding on keywords that cannibalize each other, or running ads to audiences already in your funnel. These aren't judgment calls. They're rule violations.

We've built a diagnostic framework around 22 rules that separate accounts that work from accounts that leak money. Most accounts we've reviewed fail 8 to 12 of them. If your account is underperforming, it's probably breaking at least one rule in each of these four categories.

Waste Rules (8)

Rule 1: No unqualified traffic sources. You're not bidding on competitor branded terms, misspelled variants, or obvious low-intent queries. A $2,000/mo account bidding "free" or "how to" queries might waste $300+ monthly on clicks that never convert.

Rule 2: Negative keywords block low-intent variants. Your account has a living negative keyword list that excludes seasonal, comparison, or DIY queries irrelevant to your offer. Without this, search volume looks good but conversion rate craters.

Rule 3: Match types are intentional, not defaulted. You're not running everything on Broad Match and calling it a day. Phrase Match or Exact Match keywords have explicit conversion intent; Broad Match (if used) is monitored weekly for waste. Broad Match on a $1,000 budget can leak $150+ monthly to off-target queries.

Rule 4: Display and Remarketing aren't set to broad audiences. Your Display campaigns target specific interests or placements, not everyone on the web. Remarketing lists are built from site behavior (cart abandoners, product page visitors), not just "all site visitors."

Rule 5: Bid caps prevent runaway CPCs. You've set max CPC limits per campaign or ad group so a single high-performing keyword doesn't inflate your cost per conversion across the board. If you're not capping bids, competition for premium placements can double your CPC month-over-month.

Rule 6: Geographic targeting matches your service area. You're not running national campaigns if you operate in three states. If you're local, you're not paying for clicks from outside your delivery radius. A contractor bidding nationwide instead of three metro areas can waste half their budget.

Rule 7: Ad schedule excludes low-performing hours. You have data on which hours and days convert, and you've paused or reduced bids during dead zones. A B2B company paying the same bid at 2 a.m. on Sunday as Wednesday at 10 a.m. is leaving efficiency on the table.

Rule 8: Conversion tracking captures all lead-generating events. Your account doesn't just track purchases—it logs form submissions, demo requests, phone calls, and other revenue-adjacent actions. Without this, your ROAS looks worse than it is, and you make bid decisions on incomplete data.

Structure Rules (6)

These rules ensure your account is organized so Google's algorithm works with you, not against you, and so you can actually diagnose problems.

Rule 9: One primary conversion action per campaign. Each campaign optimizes for a single conversion type (purchases, leads, calls, etc.). Mixing them signals conflicting optimization targets and tanks performance. Google doesn't know whether to chase volume or quality.

Rule 10: Keywords and ad copy align. The language in your search ads reflects the search terms you're bidding on. If your ad says "Buy Online Now" but you're bidding on "repair near me," Quality Score drops and CPC rises. Alignment improves Quality Score by 1–2 full points on average.

Rule 11: Ad groups are organized by intent, not just topic. You're not throwing 50 keywords into one ad group. Instead, ad groups cluster keywords that would all see the same ad. A home security company might have one ad group for "outdoor cameras," another for "door locks," each with tailored ad copy.

Rule 12: Landing pages are campaign- or ad group-specific. Traffic from a search ad for "leather jackets" lands on the leather jackets category page, not the homepage. Poor landing page relevance tanks Quality Score and Conversion Rate simultaneously. Campaigns with perfect LP relevance see 20–40% higher conversion rates than generic redirects.

Rule 13: Mobile experience is optimized or excluded. You've tested (or are actively testing) whether mobile converts. If it doesn't, you're either excluding mobile traffic or significantly lowering mobile bids. If it does, mobile bids are competitive with desktop.

Rule 14: Account is using conversion value, not just volume. If you have different-value conversions (a $1,500 sale vs. a $50 lead), you're passing that value to Google so it bids for quality conversions, not just any conversion. Without this, you chase cheap junk leads and leave margin on the table.

Opportunity Rules (6)

These rules flag money you could be making but aren't.

Rule 15: High-intent keywords aren't underbid. Keywords with 8+ ROAS (or 25%+ conversion rate) aren't capped at old bid levels just because the budget ran out last month. You've identified your best performers and given them room to grow. Underbidding a 10x ROAS keyword can cost you $1,000+ in lost monthly revenue.

Rule 16: You're testing Performance Max or newer campaign types. If you're running only Search campaigns in 2024, you're missing an entire distribution channel. At minimum, you've tested whether Performance Max (ads on YouTube, Display, Search, Maps, Gmail) works for your offer. For many accounts, it doubles reach with similar or better efficiency.

Rule 17: Audience signals are added to campaigns. You've created (or uploaded) audiences—past customers, high-value behaviors, lookalike audiences—and layered them into your Search campaigns as "Audience Signals" (not "Audience Exclusions"). This tells Google which searchers to prioritize. It typically lifts conversion rate 10–20% with modest CPC increases.

Rule 18: Smart Bidding strategies are being tested or used. You're not stuck on Manual CPC if your conversion data is clean. Target CPA, Target ROAS, or Maximize Conversions could be earning more revenue on the same budget. The learning period is 2–4 weeks; if you've never tested it, you're probably leaving 15–30% revenue on the table.

Rule 19: Seasonal or event-driven keywords are prepared in advance. For seasonal businesses (gift buying, tax season, back-to-school), keywords and budgets are staged 4–8 weeks before peak demand. Launching mid-season means Google's learning period overlaps peak conversion time, and you waste spend while it optimizes.

Rule 20: You're running at least one brand + category experiment. You're not only bidding on your own brand. You're also testing competitor brand terms or category-level queries to capture demand you don't own. A $3,000/mo brand-only account that adds competitor bidding often sees 40–60% revenue uplift with modest CPC increases.

Competitive Rules (2)

These rules keep your account competitive within your market.

Rule 21: Ad copy addresses a specific competitor advantage or customer pain. Your ads don't say generic things like "We're the best" or "Call today." Instead, they reference a specific advantage (fastest shipping, lowest price, highest rating, specific certification) or pain point you solve. Specific messaging usually lifts CTR 15–30% and attracts higher-intent traffic.

Rule 22: Pricing, promotions, or scarcity are visible in ad copy or extensions. If price, a current promotion, or stock scarcity is part of your offer, it's in the ad or Price Extensions. This filters out bargain hunters if you're premium-positioned, or attracts deal-seekers if you're competing on value. Accounts that show pricing see 20–40% lower-quality but higher-converting traffic.

How Many Rules Should Your Account Pass?

In a healthy account, 18 out of 22. Most accounts we've reviewed pass 10 to 12. If you're passing fewer than 15, your account is in active distress mode—rules are being broken in ways that directly reduce profitability. Start with the Waste and Structure rules; they're foundational. Opportunity and Competitive rules come next.

The good news: every single one of these rules is actionable. None of them require guesswork or creativity. They're binary checks. Either your account has intentional negative keywords, or it doesn't. Either you're tracking all conversions, or you're not. Either you're bidding on high-intent keywords, or you're chasing volume.
