Frequently asked questions

What is the best Google Ads audit tool in 2026?

It depends on the use case: for a full audit in your language without an agency, AdPredictor (free in 60 seconds; the Live audit, 14 days free and then a monthly fee). For ongoing management of many accounts, Optmyzr or Opteo. For very large accounts with complex context, an expert manual audit.

Are there free Google Ads audit tools?

Yes. AdPredictor's free AI audit analyzes your real account in 60 seconds with no card, and WordStream's Free Grader gives a quick high-level score. Free audits typically show the diagnosis; the actionable detail is usually paid.

How often should I audit my Google Ads account?

A full audit every 3-6 months, plus weekly monitoring of key signals (spend with zero conversions, quality score drops, irrelevant search terms). Accounts spending over €3,000/month deserve a monthly review.

What should a good Google Ads audit cover?

At minimum: wasted spend on keywords and search terms with no conversions, conversion tracking health, quality score distribution, bidding strategy vs goal fit, campaign structure, negative keywords, and device/location/schedule performance.
