Google Ads Account Audit and Quality Score Guide

A regular Google Ads account audit is one of the most effective ways to cut wasted spend and boost performance. In this post, we explain what to look for and why Quality Score matters so much.

What is Quality Score and why does it matter?

Quality Score is a metric on a 1–10 scale that reflects how relevant Google considers your keywords and ads. It has three main components:

• Expected click-through rate (CTR): How likely your ad is to be clicked.
• Ad relevance: How closely your ad matches the search intent.
• Landing page experience: The relevance, speed, and usability of your page.

A high Quality Score usually means a lower cost per click and better ad rank — so you get more results from the same budget.

Checklist for a healthy account

1. Account structure: Are your campaigns and ad groups organized around clear themes?
2. Low Quality Score keywords: Which ones are underperforming, and why?
3. Search terms: Have wasteful queries been added as negatives?
4. Ad copy: Does every ad group have enough relevant variations?
5. Conversion tracking: Are conversions being measured accurately?
6. Budget and bids: Is your budget flowing to the campaigns that drive the most conversions?
