The best free Google Ads audit tools

A good audit tool finds wasted spend fast. We compared the free graders on what they check, whether they make you connect your account, and how usable the report is.

Most “free” Google Ads graders require you to connect your account via OAuth and hand over an email before you see anything. This list ranks the free options by depth of audit and friction — the lower the barrier to a useful report, the higher the rank.

How We Ranked Them

  • Free to get a usable report.
  • Checks the things that actually waste spend (structure, negatives, Quality Score).
  • Low friction — minimal account connection or email gating.
  • Output you can act on, not just a vanity score.

The Rankings

1. Jupitron Google Ads Grader

An AI pass that flags structure, wasted-spend, relevance, and ad-copy gaps fast — no account connection or email required.

Best for: A fast, no-login first pass · Free

2. WordStream / LocaliQ Grader

The long-standing free grader. Thorough, but requires connecting your Google Ads account and a work email to see the report.

Best for: A deep account-connected audit · Free (account connect)

3. Google Ads Recommendations

Google's own optimization score inside the platform. Useful but biased toward more spend; treat its suggestions critically.

Best for: In-platform quick wins · Free (in account)

4. Agency manual audit

A human expert reviewing the account. The most thorough option, but slow and usually paid or pitched as a sales lead-in.

Best for: A deep, paid expert review · Paid / sales call

Frequently Asked Questions

Are free Google Ads audit tools any good?

Yes, for finding the obvious leaks — wasted spend, thin ad copy, weak structure. A free grader is a great first pass. For nuanced strategy, pair it with the audit checklist or an expert review.

Do I have to connect my account?

Not always. Some graders require OAuth account access; Jupitron's grader gives a fast first-pass review without connecting your account or handing over an email.
