The Free Google Ads Audit: What It Checks, and What It Cannot

A free Google Ads audit costs nothing and takes under a minute, and that is an accurate description of what you get. It is a fixed checklist run against whatever your account looks like today, with no memory of last month and no idea what your margin is. That is not a criticism of the tools — it is what they are built to do — but it is not the same thing as an audit, and knowing the difference saves you from either over-trusting a green checkmark or dismissing the free option when it would have genuinely helped.

I run Google Ads for ecommerce brands and get asked fairly often whether one of these free graders is worth running before hiring anyone. The honest answer is yes, and then you should know exactly what it did and did not just tell you.

What a free Google Ads audit actually checks

WordStream’s Google Ads Grader, one of the best-known free tools in this category, publishes exactly what it measures: Quality Score, wasted spend (whether you are using negative keywords), click-through rate, “account activity” (literally how much time you spend logged into the account), long-tail keyword use, ad text, landing pages, and general “PPC best practices.” Every free audit tool on page one of Google for this exact search runs some version of that same list.

• These are real checks, not fabricated ones. Quality Score and wasted spend genuinely matter, and a tool that flags zero negative keywords on an account that has none is correct to flag it.
• They are also identical for every account. The same eight categories run whether you sell a $20 product with a 70% margin or a $2,000 product with a 15% margin, and those two accounts should not be optimized the same way.
• Most require you to connect the account rather than guess from the outside, which is a real step up from a pure marketing quiz. It still only sees the account, not your actual business.

What it structurally cannot see

The checks above all look at settings and activity inside the account. None of them can answer the one question that decides whether everything downstream is pointed in the right direction: is the account measuring the right thing, correctly?

• Whether your conversion data is true. A free tool has no access to your Shopify or CRM orders, so it cannot compare what Google Ads reports against what actually sold. Google Ads lets you track several conversion types side by side and set which one counts by default (Google Ads Help, conversion tracking setup), and a tool grading your account has no way to know whether that default was ever set correctly.
• Whether branded search is inflating the whole account’s numbers. A branded campaign always looks excellent, because the people searching your name had already decided to buy. A generic grader has no baseline for how much of that is actually incremental.
• Whether Performance Max is cannibalizing traffic that was already converting. This takes comparing a campaign against what it replaced, over time — a single snapshot cannot do it.
• Whether the matching data behind your conversions is actually improving your measurement, which is what enhanced conversions are built to do (Google Ads Help, about enhanced conversions) — and whether it is switched on and actually receiving data is invisible from outside the account.
• Your actual margin and target cost per acquisition. No external tool knows what you can afford to pay for a customer, so nothing it recommends can be checked against whether it is profitable.

Who the free version is actually enough for

If your account has one or two campaigns, you have never looked at the negative keyword list, and you are not sure your Quality Scores are even average, a free grader will catch real, correctable problems and is worth the five minutes. You do not need to hire anyone to add negative keywords or turn on a best-practice setting a free tool already named for you.

The free version stops being enough once the obvious gaps are closed and the questions get specific to your business: is this campaign actually profitable at your margin, is branded search quietly doing most of the work, has the account structure survived three rebuilds and never been cleaned up. Those questions need someone looking at your order data next to the ad account, not a tool grading settings.

What a real audit starts with instead

A real audit does not start with the campaigns. It starts by checking whether the account is even measuring the truth, because every bidding decision downstream is a guess if that part is wrong. The full checklist I use when I take over an ecommerce account walks through that reconciliation first, then search terms, branded spend, Performance Max, the product feed, and the landing pages, roughly in order of what tends to be costing the most money.
