Ad quality score still matters, but it's only one piece

Executive overview

Advertisers obsess over quality score while ignoring what happens after the click. A high score means nothing if the landing page, checkout flow, and follow-up sequences don't convert.

Optimise the whole funnel — ad relevance, landing page match, and post-purchase experience — not just the ad itself.

A quality score of 10 is worthless if no one converts.

What quality score actually measures

• Scored 1–10 by Google and Bing to rank ads against competitors
• Lower scores mean higher costs; higher scores mean cheaper, more visible ads
• Affected by keyword relevance, ad copy, landing page experience, and click-through rate

The most common mistakes

• Focusing only on ad copy and targeting, ignoring the landing page
• Mismatched intent: ad targets "nails" (hardware) but lands on press-on nails
• Keyword ambiguity ignored — Apple the fruit vs Apple the computer
• Running the same creative for months without rotation

Optimising beyond the ad

• Rotate ad copy and images regularly; fresh creative sustains quality score and click-through rate
• Match the language and offer precisely between ad and landing page
• Don't stop at the click — optimise the full funnel including checkout, upsells, and follow-up sequences

Revenue is the only metric that matters

• Platform metrics (CTR, quality score) look good at the ad level but don't reflect business outcomes
• Amazon's model illustrates the real goal: one acquisition, recurring revenue from repeat purchases
• Marketing's job is to bring the customer to the point of sale — anything short of that is a failure
