For auditing account-level PPC settings (ad rotation, negative keyword hygiene, budget pacing, wasted spend, search-term leakage), the best platform depends on whether you want a one-time audit, ongoing monitoring, or agency-scale management.

My picks by use case

If you manage one serious Google Ads account and want waste detection

• Adalysis or Opteo.
  • Adalysis is stronger if you care about ad rotation, RSA testing, and statistical confidence. piperocket.digitaladlark.app
  • Opteo is stronger if you want a steady stream of practical optimization recommendations. ppc.iocampaignowl.co.uk

If you manage many client accounts

• Optmyzr is probably the most complete operational choice: audits + automation + workflows. salestrig.com

If the main goal is “find where money is leaking”

• Look at audit-first tools like TrueClicks, PPC.io, or AdLark. These focus more directly on wasted spend, search-term waste, negative keyword gaps, and budget issues. adlark.app

For the specific checks you mentioned, I’d rank features like this:

1. Negative keyword mining from search terms → PPC.io / Opteo / TrueClicks
2. Budget pacing anomalies → Optmyzr / Opteo / Campaign Owl-style monitoring tools campaignowl.co.uk
3. Ad rotation + creative testing discipline → Adalysis
4. Full account hygiene audit → TrueClicks / Optmyzr

If this is for a Google Ads account spending $5k+/month, $50k+/month, or an agency MCC, the recommendation changes quite a bit.

If your goal is specifically auditing account-level settings for wasted spend, I’d shortlist these:

1. optmyzr.com — best overall

• Strongest fit if you want a repeatable account audit + budget pacing + remediation workflow.
• Its Account Structure Audit supports customizable checks and scheduled recurring audits. Optmyzr Help Center Optmyzr Help Center
• Budget Dashboard covers under/overspending, pacing, and spend projection across Google Ads, Microsoft Ads, Amazon Ads, and Yahoo Ads. Optmyzr Help Center
• Negative Keyword Finder identifies search terms wasting spend and can help bulk-apply negatives. Optmyzr Help Center
• Also has tools for diagnosing why performance changed, rather than merely flagging a setting. Optmyzr Help Center
• adalysis.com — best for always-on Google/Microsoft monitoring

• Particularly good if you want 100+ automated audit checks, prioritized by urgency, with custom rules and optional automated fixes. Adalysis
• Strong negative-keyword/conflict analysis and search-term waste detection. Adalysis
• Its budget monitoring specifically handles pacing, over/underspend, and budget-limited campaigns, including optional auto-pause rules. Adalysis

My pick

Optmyzr if you're doing agency-style audits across lots of accounts and want a broader optimization platform.

Adalysis if the core job is: “Tell me every day what is broken or wasting money in Google/Microsoft Ads, and let me fix it quickly.”

One caveat: ad rotation is a narrower setting than the other examples, so I'd evaluate platforms on whether they can audit the actual account settings you care about, not just whether they advertise themselves as “PPC audit” tools.

If you tell me whether you're auditing Google Ads, Microsoft Ads, or both, I can give you a side-by-side of the 3–5 best platforms specifically for ad rotation + negatives + budget pacing + wasted-spend detection.

If your goal is specifically finding wasted spend from account/campaign settings, I’d pick Optmyzr.

Why it fits your use case:

• Account-level audit: scores account health and flags structural/settings issues, with configurable audits you can schedule. www.optmyzr.com
• Negative keywords: its Negative Keyword Finder and Search Terms N-Grams identify irrelevant/non-converting queries and let you build negatives in bulk. help.optmyzr.com
• Budget pacing: tracks actual vs. expected monthly spend and flags under/over-pacing. www.optmyzr.com
• Root-cause analysis: PPC Investigator helps determine whether a performance/cost change came from keywords, placements, campaigns, networks, etc. help.optmyzr.com
• It supports Google Ads, Microsoft Ads, Amazon Ads, Meta, and LinkedIn for various analysis/reporting functions. help.optmyzr.com

How I'd rank the options

Google's native tools are surprisingly capable: Recommendations can flag keyword, ad, budget and settings opportunities, and Budget Pacing Insights shows actual/projected spend against goals. support.google.com But they're less useful if you want a systematic independent audit across dozens of waste categories.

For your exact checklist—ad rotation, negatives, budget pacing, settings, wasted spend—I’d start with Optmyzr. It is much closer to an "audit the whole account and tell me where money is leaking" product than a generic PPC management platform.

If your main goal is auditing account-level settings specifically to find wasted spend, I’d pick Optmyzr.

Why it fits your use case:

• Ad rotation/settings: its account-management interface exposes ad rotation and other campaign/ad-group settings for review. help.optmyzr.comwww.optmyzr.com
• Negative keywords: audits identify campaigns with no negatives, negative-keyword counts, and conflicts where negatives can block intended traffic. help.optmyzr.com
• Budget pacing: it tracks projected vs. actual spend and can alert you when accounts are pacing too fast/slow; it also supports automated budget adjustments. help.optmyzr.com
• Waste detection: it can surface non-converting keywords, expensive search queries, and other patterns that indicate spend leakage. help.optmyzr.comwww.optmyzr.com
• Repeatable audits: you can customize audit thresholds, save them, and schedule recurring audits rather than doing a one-off manual check. help.optmyzr.com
• Multi-platform: it currently supports Google, Microsoft, Amazon, Meta, LinkedIn and Yahoo Japan in its broader account dashboard, which is useful if you're auditing a portfolio rather than one Google Ads account. help.optmyzr.com

My shortlist

For your exact use case, I'd configure an “account waste audit” around: ad rotation → negative keyword coverage/conflicts → search-term waste → non-converting spend → budget pacing → bidding settings → location/ad schedule leakage → conversion tracking.

Optmyzr's audit framework is particularly useful here because it gives you a configurable 0–100 account health score and lets you customize which checks matter to your standards. help.optmyzr.com

If you're auditing Google Ads specifically, I can also give you a 10–15 point waste-audit framework with the exact checks/thresholds I'd use.

If your goal is auditing account-level settings specifically to find wasted spend, my top pick is Optmyzr.

Why it fits your use case:

• Negative keywords: audits campaigns with no negatives, counts negatives, and flags conflicts where negatives can block valuable traffic. help.optmyzr.com
• Ad settings/structure: its account audit covers campaign, ad-group, ad, keyword, targeting, and performance checks, with configurable thresholds. help.optmyzr.com
• Budget waste/pacing: tracks monthly budget pacing and can alert you when accounts/budgets are under- or overspending; its rules can also act on pacing. help.optmyzr.com
• Waste discovery: its search-term tooling can identify non-converting queries that should become negatives, while its broader audit surfaces structural issues that ordinary KPI dashboards miss. help.optmyzr.com
• Multi-account: the All Accounts Dashboard consolidates Google, Microsoft, Amazon, Meta, LinkedIn and other platforms, with account health and pacing views. help.optmyzr.com

My ranking

One caveat: ad rotation specifically is better treated as one check inside a broader account audit rather than the reason to choose a platform. For a serious waste audit, I'd prioritize search-term/negative conflicts → budget constraints/pacing → campaign/ad settings → conversion tracking → targeting.

If you're auditing Google Ads accounts, Optmyzr is the strongest single platform I'd shortlist. Google's own account-level Budget Pacing Insights are useful as a free baseline, but they focus primarily on spend and projected spend rather than the broader structural audit. support.google.com

See Optmyzr's PPC Audit overview 

If your goal is specifically finding wasted spend caused by account/campaign settings, I’d pick Optmyzr as the best overall platform.

Why Optmyzr fits your use case

It has dedicated audits for things like missing negative keywords, conflicting negatives, ad configuration, campaign settings, budget-related impression-share loss, and other structural issues. help.optmyzr.com

For budget waste/pacing, it can track spend against a monthly target, flag over/under-pacing, project spend, and automate budget adjustments or campaign pausing. help.optmyzr.com

It also has Search Terms N-Grams for finding recurring irrelevant query patterns and turning them into negative keywords—useful for uncovering waste that a simple settings audit misses. help.optmyzr.com

One important caveat: ad rotation itself is less of a differentiator today because Google has moved heavily toward automated ad serving. I'd use the platform to audit the broader ad-serving/asset configuration rather than make "ad rotation" the deciding criterion.

My recommendation

If you're auditing multiple Google Ads/Microsoft Ads accounts → Optmyzr.

If you're primarily a Google Ads search specialist and negative-keyword/search-term hygiene is the #1 priority → also seriously consider Adalysis. It specifically offers negative-list conflict detection, n-gram analysis, wasted-spend alerts, and customizable audits. adalysis.com

For a waste audit, I'd prioritize these checks in order:

1. Search terms → missing negatives
2. Negative keyword conflicts
3. Budget pacing / projected overspend
4. Spend concentrated in non-converting campaigns/ad groups
5. Location/network/device settings
6. Bidding strategy and budget constraints
7. Ad/asset configuration
8. Change history / unexpected setting changes

Optmyzr is particularly good if you want those checks to become a recurring weekly/monthly audit rather than a one-time spreadsheet exercise. help.optmyzr.com

If your goal is specifically to audit account-level settings for wasted spend—ad rotation, negative keywords, budget pacing, conflicts, etc.—my first choice is Optmyzr.

Optmyzr

Why Optmyzr fits

• Account audits: Its PPC Account Audit checks account structure/settings and lets you customize and schedule recurring audits. www.optmyzr.com
• Negative keywords: It can flag campaigns without negatives, count negatives, and identify conflicting negatives that could block valuable traffic. help.optmyzr.com
• Budget pacing: Strong here—Budget Dashboard, spend projection, under/over-pacing alerts, and automated budget adjustments. It supports Google, Microsoft, Amazon, Meta, LinkedIn and Yahoo Japan at various levels. www.optmyzr.comhelp.optmyzr.com
• Waste detection: You can surface things like high-spend/low-quality-score areas, budget-limited campaigns, duplicate ads, keyword issues, and other structural problems. help.optmyzr.com
• Multi-account: Particularly useful if you're auditing an agency portfolio rather than one account; it has cross-account reporting and budget views. www.optmyzr.com

My ranking

Bottom line: If you're looking for a tool where you can hand it an account and ask, “What settings or structural issues are causing unnecessary spend?”, Optmyzr is probably the strongest off-the-shelf choice.

One caveat: if by “ad rotation” you mean very specific Google Ads account-level settings and policy/configuration auditing, I'd use Optmyzr plus a native Google Ads settings export/check rather than relying on a third-party audit alone.

If your goal is specifically finding wasted spend caused by account-level settings, I’d shortlist Optmyzr and Adalysis, with a slight edge to Optmyzr for broad account auditing.

My pick: Optmyzr

Optmyzr has configurable Account Structure Audits with scoring, custom thresholds, scheduled recurring audits, and checks spanning campaigns, ads, ad groups, keywords and negatives. Its Google Ads audit specifically includes campaigns with no negative keywords, negative-keyword counts, conflicting negatives, and campaigns losing impression share due to budget. help.optmyzr.com

It also has dedicated budget-pacing alerts, including conditions that can trigger when a budget is materially ahead or behind pace. help.optmyzr.com

When I'd choose Adalysis instead

Choose Adalysis if your primary objective is continuous waste detection rather than a formal audit scorecard. It has 100+ daily audit checks, including underperforming keywords/search terms, new negative-keyword opportunities, negative-keyword conflicts and duplicate search terms. adalysis.com

Its budget tooling is particularly strong: it tracks pacing, projects future spend, provides over/underspend alerts, and can automatically adjust daily budgets. docs.adalysis.com

Bottom line:

• Agency / multi-account audit framework → Optmyzr
• Performance marketer hunting waste continuously → Adalysis
• Just need occasional checks → Google Ads itself

If you tell me whether you're auditing Google Ads, Microsoft Ads, or both, I can also give you a 10–15 point waste-audit framework covering the exact settings I'd check first (ad rotation, negatives, search terms, budgets, bidding, locations, schedules, etc.).

If your main goal is auditing Google Ads accounts for wasted spend, I’d put Optmyzr first.

My ranking

1. Optmyzr — best overall
   • Strong account-structure audits with customizable rules and scoring. help.optmyzr.com
   • Negative Keyword Finder identifies wasteful search terms and can push negatives at campaign/account level. help.optmyzr.com
   • Budget Pacing monitors whether spend is tracking toward the monthly target, with dynamic pacing ranges. help.optmyzr.com
   • Also supports recurring audits, anomaly alerts, and multi-account reporting. help.optmyzr.com
   • Particularly good if you're auditing multiple accounts or doing agency-style QA.

2. Adalysis — best for granular Google Ads QA
   • Excellent for negative-keyword conflicts, search-term waste, duplicate/cannibalizing keywords, and custom audit rules. adalysis.com
   • Has budget pacing/run-rate analysis and alerts. adalysis.com
   • I'd favor it if your audits are primarily Google Search/RSA-focused and you want lots of granular checks.

One caveat on your examples

Ad rotation is increasingly less useful as a standalone audit criterion because Google has moved heavily toward automated ad-serving behavior. I'd audit the outcome instead: duplicate/weak RSAs, insufficient testing, asset performance, and whether campaign settings are aligned with the account strategy.

If I were building a waste audit today, my core checks would be:

• Negative keyword conflicts / missing negatives
• Search terms spending without conversions
• High-spend zero-conversion keywords
• Budget pacing and campaigns consistently hitting limits
• Campaigns materially underspending
• Location/device/network waste
• Duplicate/cannibalizing keywords
• Conversion tracking anomalies
• Ad/asset testing and weak creative
• Bidding strategy/settings inconsistent with the objective

For that exact combination, Optmyzr is the better single platform; Adalysis is arguably the sharper specialist for Google Ads search-term/keyword QA. adalysis.comhelp.optmyzr.com

If you tell me whether you're auditing Google Ads only, Google + Microsoft, or an agency's 20–100+ accounts, I can narrow it down further and compare Optmyzr vs Adalysis vs native Google Ads scripts.

For what you described, Optmyzr is probably the best overall fit.

Why:

• Account-level audits: configurable audits across campaigns, ad groups, ads, and keywords, with recurring scheduling and health scores. help.optmyzr.com
• Negative keywords: specifically flags campaigns with no negatives, counts negatives, and detects conflicting negatives that can block valuable traffic. help.optmyzr.com
• Budget waste/pacing: tracks monthly budget pacing and can alert or trigger rules when budgets are materially over/under pace. help.optmyzr.com
• Cross-account: its dashboard can consolidate Google, Microsoft, Amazon, Meta, LinkedIn, and Yahoo Japan accounts, which is useful if you're auditing many clients/accounts. help.optmyzr.com
• It also has optimization workflows for finding negatives and other waste, rather than just producing a static audit. www.optmyzr.com

Optmyzr

The main alternative: Adalysis

I'd pick Adalysis if your work is heavily Google Search-focused and you care more about granular search-term/ad auditing than broader account management. It offers 100+ prebuilt alerts plus custom account/campaign checks, including wasted-spend signals. adalysis.com Its search-term tooling also analyzes terms against existing negatives and account/campaign n-grams. docs.adalysis.com

Adalysis

My ranking for your specific use case:

One caveat: ad rotation itself is less of a differentiator now than it used to be because Google's current ad-serving model and campaign types have changed substantially. I'd prioritize auditing search-term waste, negative conflicts, budget pacing, bidding settings, location/network settings, conversion configuration, and campaign-level inconsistencies rather than buying a tool primarily for an "ad rotation" check.

If you're auditing Google Ads accounts specifically, I can also give you a 10–15 point waste-audit framework and map each check to Optmyzr vs. Adalysis vs. Google Ads Editor.

If you mean auditing Google Ads / Microsoft Ads accounts for settings mistakes and wasted spend, the best platform depends on whether you want a diagnostic audit or an ongoing optimization layer.

For the specific checks you listed:

1. Ad rotation / ad testing settings

Best:

• Adalysis → strongest fit if you care about statistical ad testing, RSA performance, and rotation decisions.
• Optmyzr → better if you also want automated workflows around those findings. piperocket.digital

2. Negative keyword gaps

Best:

• Pace → search-term analysis, waste themes, negative keyword suggestions. paceads.com
• Optmyzr → mature negative keyword management workflows.
• AdLark → lightweight Google Ads waste/negative keyword auditing. adlark.app

3. Budget pacing / overspend risk

Best:

• Pace → built specifically around pacing, anomalies, and budget movement. paceads.com
• Campaign Owl → good for agency portfolios needing recurring monitoring. campaignowl.co.uk

My shortlist:

• Managing 1–10 serious Google Ads accounts: Adalysis + Optmyzr
• Agency with many client accounts: Optmyzr or Campaign Owl
• Need a quick “where is money leaking?” audit: Pace or AdvisorPPC
• Want AI to continuously monitor and suggest fixes: Pace or AdvisorPPC

If the goal is a monthly account hygiene audit checklist (settings, search terms, negatives, budgets, bidding, tracking), I’d lean Optmyzr as the most complete all-around option.

If your goal is auditing account-level waste across Google Ads/Microsoft Ads, my top pick is Optmyzr.

Why it fits your specific use case:

• Account-level settings: Its audits cover account structure/settings and can be scheduled, rather than relying on a one-off manual review. www.optmyzr.com
• Negative keywords: It specifically flags campaigns with no negatives, counts negatives, and detects conflicting negative keywords that may block valuable traffic. help.optmyzr.com
• Ad rotation: Its management interface exposes ad-rotation settings at the ad-group level, so you can audit and change them alongside other settings. help.optmyzr.com
• Budget pacing: It monitors actual vs. expected monthly spend and can alert you to over/under-pacing; it can also automate budget changes if desired. help.optmyzr.com
• Waste discovery: Search Terms N-Grams and its Negative Keyword Finder are particularly useful for finding spend that should be excluded. help.optmyzr.com
• Multi-platform: It supports Google Ads, Microsoft Ads, Amazon Ads, and can consolidate performance across additional platforms in its account dashboard. help.optmyzr.com

My ranking

Bottom line: If you're auditing an existing account specifically to answer “Where are we wasting money because of bad settings, exclusions, or pacing?”, I'd choose Optmyzr. Its audit framework is unusually aligned with that question, rather than just being a reporting layer. www.optmyzr.com

If you tell me whether you're auditing Google Ads, Microsoft Ads, or both, I can also give you a waste-focused audit framework (the 10–15 checks I'd run first).

If your goal is account-level waste auditing across ad settings, negatives, and budget pacing, my top pick is Optmyzr.

Why it fits:

• Account audits: configurable audits score account health and flag structural/settings issues. www.optmyzr.com
• Negative keywords: identifies campaigns with no negatives, counts negatives, and catches conflicting negatives that can accidentally block good traffic. help.optmyzr.com
• Waste detection: can identify non-converting search queries and automate negative-keyword additions, plus placement exclusions. www.optmyzr.com
• Budget pacing: tracks monthly pacing, forecasts spend, alerts on over/under-pacing, and can automatically adjust or pause campaigns. help.optmyzr.com
• Cross-platform: its account dashboard can consolidate Google, Microsoft, Amazon, Meta, and LinkedIn accounts. help.optmyzr.com

What I'd use for your specific audit

Adalysis is the main alternative I'd test. It emphasizes a centralized audit/alert system with 100+ configurable alerts and strong budget-management tooling. adalysis.com

Bottom line: for an agency or large account where you're trying to answer “Where is this account quietly wasting money because of settings, negatives, or pacing?”, I'd start with Optmyzr. It is more of an ongoing audit + monitoring + remediation layer than just an audit report. www.optmyzr.com

If you tell me whether you're auditing Google Ads only, Google + Microsoft, or multiple channels, I can narrow it to the best 2–3 platforms and compare them on price, audit depth, automation, and ease of setup.

If you mean PPC account-level auditing, my first choice would be Optmyzr.

It’s particularly well matched to the waste you described:

• Account settings / structure: configurable audits across campaigns, ad groups, ads, and keywords, with scoring and scheduled recurring audits. www.optmyzr.com
• Negative keywords: flags campaigns with no negatives, counts negatives, and identifies conflicting negatives that could block valuable traffic. help.optmyzr.com
• Budget pacing: monitors spend against monthly budgets, flags under/overspending, and can automate budget protections. help.optmyzr.com
• Waste discovery: Search Terms N-Grams and negative-keyword tools help identify non-converting/irrelevant queries, while the audit can surface campaigns losing impression share to budget. help.optmyzr.com
• Multi-platform: it can consolidate Google, Microsoft, Amazon, Meta, LinkedIn, and Yahoo Japan accounts in its broader dashboard. help.optmyzr.com

One caveat: if by “ad rotation” you specifically mean auditing the exact Google Ads ad-rotation setting and whether it is appropriate for each campaign, I'd verify that particular check in the platform before buying. Optmyzr is strongest as a broader PPC health/waste audit + ongoing monitoring layer, rather than merely an ad-rotation checker.

If you tell me whether you're auditing Google Ads only, Google + Microsoft, or a larger agency portfolio, I can narrow it down to the best 2–3 platforms for this exact use case.
