ROAS vs. CPA in Google Ads: Choose the Bid Goal That Protects Profit
CPA treats conversions equally. ROAS weights them by value. Use this practical framework to choose the right Google Ads bid goal based on margin, conversion value, and data volume.

Direct answer: A Google Ads grader (also searched as "AdWords grader", "WordStream Google Ads grader", or "WordStream performance grader") is a free account-audit tool that assigns your Google Ads account a score. The score is a point-in-time snapshot: it can surface issues, but it does not fix them, optimize them, or manage the account afterward. groas is a fully autonomous Google Ads management service that executes the fixes—bids, budgets, keywords, ads, and landing pages—168 hours a week, with a named account manager who answers for the outcome.
Free account graders belong to the audit-based tool category: they read your account and surface problems. groas's own comparison of TrueClicks and groas frames this category as "audit-based Google Ads tools" versus "fully autonomous management". The value of an audit is that you see what is wrong; the limitation is that audits don't act.
The core output of a grader is a number—a score out of 100, a letter grade, or a similar rating—together with a list of flagged issues. Different tools weigh different signals, and some variants focus on a single component such as landing page experience. A score is useful as a starting point, but it describes the account as of the moment it ran.
A one-time grade and a management system are different products. A grader misses four things that groas's model is built around:
Use a grader as a diagnostic, then decide who executes. You can try to fix the list yourself, hire an agency, or move to a service like groas that does the work continuously.
groas pricing starts at $999/month with the first 7 days free, covering Google Ads built and run for you, unlimited individual ad accounts and campaigns within the tier, and up to $15,000 in monthly ad spend. Organic search is available at the same price for a different scope. If you want to see the engine work before paying, groas offers a 7-day free trial that starts when the engine goes live.
An ad grader (or AdWords grader) is a free audit tool that scores your Google Ads account. It's a snapshot of account health, not a system that manages the account.
The WordStream Performance Grader is a free grader that scores account health (WordStream). It belongs to the same audit-based category as other graders: it surfaces issues but does not execute fixes. For execution, you need a managed service like groas.
A score from WordStream's performance grader is static. It misses what happens after the audit: continuous bid management, budget reallocation, ad testing, and landing page changes. groas covers those tasks 24/7.
A Google Ads landing page grader is a variant that scores landing page experience, a component of Google's Quality Score. A grade tells you whether your page is weak; it does not strengthen the page. groas's paid search engine deploys dynamic landing pages that reshape around each search query.
"Adsgrader" is a common way users type "ad grader." The intent is the same: to get a score of a Google Ads account. The answer is the same too: a score is a diagnosis, not a fix.
