The best search-term & negative-keyword tools

Search terms are where budget quietly leaks. These tools surface the wasted queries and queue the negatives — the good ones keep a human approving the writes, the great ones don’t make you pay per account.

The short answer

Adalysis is the best dedicated search-term/negative-keyword tool for most operators (n-gram analysis, unlimited accounts, automated negatives). TrueClicks is the standout if you’re cost-sensitive — free under $50k/month ad spend. Opteo is the $129 simple option. Optmyzr is the choice only when you want the deepest rule engine and are scaling.

Adalysis

Purpose-built search-term & negative-keyword copilot

Best overall

Adalysis’s strongest feature is its n-gram search-term analysis and “add as negative” workflows — it finds the wasted queries and can automate the negative application on a schedule. It also gives you unlimited Google + Microsoft accounts and users on every plan, which is rare.

Best for

  • Search-term / negative-keyword hygiene specifically
  • Agencies that want unlimited accounts per fee
  • Teams replacing spreadsheet-based search-term review

Not for

  • Cross-channel beyond Google/Microsoft
  • Buyers wanting a true generative AI assistant (its core is rules-driven)
Pricing: single tier set priced by max monthly ad spend (unlimited accounts/users). Exact entry price not verifiable from static text — price needs review. Verified 2026-08-27.

TrueClicks

Free monitoring + bulk fixes under $50k/month ad spend

Best free tier

TrueClicks runs 100+ best-practice checks against your accounts and gives a score with bulk “fix” buttons — strong for catching search-term waste, conflicting keywords, and hygiene issues across Google and Microsoft. The free-forever tier (up to $50k/month spend) is the best deal in this category.

Best for

  • Cost-sensitive solo agencies (free under $50k spend)
  • Client-facing QA/audits before a competitor finds the issue

Not for

  • Deep custom rule-building (lighter than Optmyzr)
  • Spend-based pricing gets expensive past ~$500k/month
Pricing: free up to $50k/month ad spend; paid ≈0.25% of spend (e.g. ~$249/mo at $100k spend). Verified 2026-08-27.

Opteo

Simple Google Ads suggestions + bad-traffic exclusions

Simplest

Opteo is the gentlest on-ramp: a clean list of “stop here, fix this” improvements, keyword management, and bad-traffic exclusions. It’s not the most powerful, but it’s the easiest to adopt for a solo PPC manager.

Best for

  • Beginners and solo managers wanting low-effort guidance
  • A clean $129 entry point

Not for

  • Microsoft Ads (Google only)
  • Granular n-gram analysis or custom rule engines
Pricing: Basic $129/mo (10 accounts, $25k spend), Professional $249/mo, Agency $499/mo. Verified 2026-08-27.

Optmyzr

Deep rule engine + n-gram mining for scaling books

Most powerful

Optmyzr’s rule engine, n-gram search-query analyzer, and hourly automations make it the strongest option — if you’re managing many accounts and can absorb the cost and learning curve. For search terms alone, smaller shops rarely need this much.

Best for

  • Agencies scaling past ~25+ accounts and wanting deep automation

Not for

  • Solo operators on a tight budget
  • Anyone wanting a simple tool (steep learning curve)
Pricing: spend-tiered, $ figure not verifiable — price needs review.

What’s the cheapest way to clean up search terms?
TrueClicks is free under $50k/month ad spend. Opteo is $129/mo. Beyond that, Adalysis is the strongest dedicated tool but is spend-tiered.
Do these tools add negatives automatically?
Adalysis and Optmyzr can schedule automated negative application. We recommend keeping a human approval step on anything that touches live accounts.
There are a lot of new “AI negative keyword” tools — are they any good?
There’s been a wave of niche entrants (Negator, NegativeFinder, NegNeg, Cascader, and others). We haven’t hand-tested them yet, so they’re not ranked here — we prefer tools with a track record and clear pricing.
