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.
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
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)
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)
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
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.
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.
