The 40-Point Google Ads & PPC Account Audit Checklist (2026)

Check Recommendations > Auto-apply. If options like "Add new keywords", "Use optimized targeting", or "Expand your reach with Google Search partners" are toggled ON, Google's algorithms are silently injecting untargeted broad keywords and adjusting bids without human oversight. Ensure all speculative auto-apply toggles are disabled immediately.

Verify campaign location target settings. Google defaults to "Presence or interest: People in, regularly in, or who've shown interest in your targeted locations". This silently bleeds spend to international clicks from users merely researching your country. Every campaign must be strictly set to "Presence: People in or regularly in your targeted locations".

In standard Search campaigns, segment data by Network (with search partners). Google Search Network Display Expansion frequently consumes 10%–25% of Search budgets on low-intent mobile gaming banners and ad networks with near-zero conversion intent. Disable "Include Google Display Network" on all pure Search campaigns.

Audit whether campaigns are configured without goals or assigned improper objectives. If an e-commerce campaign targeting ROAS is set to "Maximize Clicks", Smart Bidding will aggressively buy the cheapest, lowest-intent desktop impressions rather than purchasers.

Check monthly conversion volume per campaign. Modern Smart Bidding algorithms require a minimum of 30–50 conversions per month per bid strategy to exit learning mode. Accounts fragmented into 40 tiny campaigns with 3 conversions each suffer perpetual bid volatility. Consolidate into structured clusters or utilize Portfolio Bid Strategies.

Never combine brand search queries with generic non-brand keywords in the same campaign. Brand search artificially inflates campaign ROAS (e.g., reporting 8x ROAS while non-brand is losing money at 0.7x), hiding massive capital erosion from leadership.

Ensure account time zone aligns with your primary CRM or e-commerce store time zone to prevent day-parting attribution discrepancies, and confirm that automated payment methods have backup cards configured to avoid sudden billing holds.

Download the Search Terms report for the last 90 days. Filter for queries with > 5 clicks and 0 conversions. In neglected accounts, this reveals thousands of dollars spent on queries completely outside commercial intent (e.g., technical support queries, login portals, DIY tutorials).

Audit shared negative keyword lists at the account level. Verify active exclusion of universal waste terms: "free, crack, torrent, jobs, salary, careers, resume, meaning, definition, wholesale, cheap, login, portal".

Broad Match in 2026 relies heavily on user search history and landing page semantics. When running Broad Match alongside Exact Match, ensure high-converting Exact Match terms are added as exact negative keywords in Broad campaigns to prevent Broad from stealing historical conversion signals.

Google's "Exact Match" now matches queries that algorithms deem to share the "same meaning". Inspect exact match search terms to detect close variant drift where Google matched queries with completely different user intent.

Ensure upper-funnel generic campaigns explicitly exclude your product-specific, high-intent BoFu keywords, forcing auctions into the exact ad group and landing page tailored for that searcher.

If bidding on rival brand keywords, verify they are cordoned into a dedicated Competitor Conquesting campaign with custom comparison landing pages and distinct tCPA targets.

Run Google's negative keyword conflict tool to verify that an over-zealous phrase or broad negative keyword hasn't blocked your primary revenue-driving exact keywords from entering the auction.

Inspect PMax settings. If "Final URL expansion" is toggled ON, Google can dynamically redirect ad clicks to blog posts, privacy policies, terms of service, or career pages. Toggle it OFF or apply strict URL exclusion rules.

Without a Brand Exclusion list applied, PMax will systematically bid on your brand name, claiming easy brand conversions and reporting an inflated 7x–10x ROAS while delivering near-zero incremental acquisition.

Utilize Google Ads PMax scripts to deconstruct where your budget is actually dispersing across Shopping, Search, Video, and Display channels (refer to our complete PMax Deconstruction Guide).

If you do not upload dedicated horizontal, vertical, and square video assets to an Asset Group, Google will automatically synthesize a low-quality slideshow video with robotic voiceovers and distribute it across YouTube and Display. Always upload custom, professionally produced video assets.

For eCommerce accounts, verify product feed health. Are titles formatted with high-intent keywords (Brand + Product Type + Gender + Size + Color)? Are GTINs/MPNs valid? Missing product identifiers cripple Shopping auction eligibility.

Ensure PMax asset groups are seeded with robust first-party audience signals: customer match lists (high LTV purchasers), GA4 purchase cohorts, and custom search intent segments (users searching your top 10 commercial keywords).

Avoid dumping 500 diverse product SKUs into a single PMax Asset Group. Segment asset groups by product category or margin tier so headlines, imagery, and landing pages remain tightly relevant.

Inspect Goals > Conversions > Summary. Only genuine bottom-of-funnel business actions (Purchases, Qualified Lead Forms, Booked Calls) should be marked as "Primary". If soft actions like "Add to Cart", "Pageview", or "Time on Site > 2 mins" are marked Primary, Smart Bidding will aggressively optimize for worthless browsing.

Verify Enhanced Conversions status in Google Ads diagnostics. With third-party cookie phaseouts and Safari ITP restrictions, Enhanced Conversions hashes first-party customer data (SHA-256 email, phone, address) to recover 5%–15% of lost conversion volume.

For eCommerce accounts, inspect whether purchase conversion tags pass unique transaction_id parameters. Without transaction IDs, when a customer refreshes their order confirmation page, Google records duplicate purchase conversions, massively corrupting ROAS.

Ensure all primary conversion actions utilize Data-Driven Attribution (DDA) rather than archaic First-Click or Last-Click models. DDA distributes credit algorithmically across touchpoints, preventing premature pausing of high-assist mid-funnel campaigns.

In B2B lead generation, raw form fills are often spam or unqualified. Verify that your CRM (HubSpot, Salesforce) syncs offline pipeline stage changes (MQL → SQL → Closed-Won) back to Google Ads using GCLID, GBRAID, or WBRAID identifiers.

Utilize Google Ads Conversion Value Rules to instruct algorithms to bid more aggressively on high-margin audiences (e.g. multiply conversion value by 1.3x for returning customers or high-tier metropolitan ZIP codes).

Verify Google Consent Mode v2 implementation (ad_storage, ad_user_data, ad_personalization). Missing consent signals prevent audience remarketing lists from populating in European and global jurisdictions.

A frequent agency mistake is setting a target ROAS of 600% when the historical baseline is 280%. The bidding algorithm responds by choking impression volume and only entering uncompetitive, low-volume auctions. Target ROAS should be calibrated within ±15% of historical 30-day realized performance before stepping up gradually.

Check bid strategy change history. Sudden budget increases exceeding 20% reset the machine learning model, throwing campaigns into volatile learning phases. Scale budgets incrementally by ≤ 20% every 72 hours.

Analyze competitive metrics. If Search Lost IS (Budget) > 25%, your campaign is profitable but artificially capped by insufficient daily budget. If Search Lost IS (Rank) > 40%, your bids or ad Quality Scores are uncompetitive, requiring asset restructuring or target CPA loosening.

When using Target CPA, device bid adjustments modify your target CPA rather than your base bid. Ensure media buyers haven't set conflicting device bid adjustments (-50% mobile) that accidentally cut your CPA target in half, killing mobile volume.

In competitive B2B or legal auctions, automated bidding can unpredictably spike individual clicks to $80+. Utilize Portfolio Bid Strategies with maximum CPC bid limits to establish hard guardrails against auction volatility.

Inspect Auction Insights reports over 30, 60, and 90-day windows. Identify which competitors are aggressively increasing impression share or outranking share, signaling aggressive pricing pressure or promotional campaigns.

For major short-term promotional bursts (Black Friday, 48-hour flash sales), apply Google Ads Seasonality Adjustments. This informs Smart Bidding of an expected temporary conversion rate surge (≥ 30%) without corrupting post-event bidding behavior.

Ensure each RSA leverages 12–15 distinct headlines and 4 descriptions. Avoid the rookie mistake of pinning headlines to Position 1 across every variant, which disables Google's combinatorial testing algorithms and drops Ad Strength to "Poor".

Assets significantly expand SERP pixel real estate and directly improve Ad Rank. Every campaign must deploy: Sitelinks (min 4 with descriptions), Callouts (min 4), Structured Snippets, Image Assets, Call Assets, and Business Logo/Name verification.

Isolate keywords with Quality Score ≤ 5. Deconstruct the three underlying pillars: Expected CTR, Ad Relevance, and Landing Page Experience. A low Expected CTR requires ad copy testing; a low Landing Page Experience requires message match and Core Web Vitals optimization.

Every 100ms delay in mobile landing page loading drops conversion rates by 7%. Run PageSpeed Insights on all ad landing pages to verify healthy Interaction to Next Paint (≤ 200ms) and LCP (≤ 2.5s) (see our INP PPC Optimization Guide).

Audit the exact promise made in your ad headline against the primary H1 header above the fold on the landing page. If an ad promises "Save 30% on ERP Software" and the landing page merely displays a generic home page hero, conversion rates collapse by over 60%.
