Google Ads Quality Score: How It Works and How to Improve It

Quality Score is Google assessment of the quality and relevance of your keywords, ads, and landing pages. A higher Quality Score means lower costs per click and better ad positions — the same budget goes further.

Three components determine Quality Score: expected click-through rate (how likely people are to click your ad), ad relevance (how closely your ad matches the search intent), and landing page experience (how useful and relevant your landing page is to people who click).

Expected click-through rate: this predicts how likely your ad is to be clicked based on its past performance relative to its position. Improve it by writing compelling ad copy with strong value propositions, using keywords in headlines, and including extensions that make your ad larger and more informative.

Ad relevance: this measures how closely your ad text relates to the keyword. Improve it by organizing campaigns into tightly themed ad groups where every keyword, ad, and landing page align around a single topic. Avoid broad ad groups that mix unrelated keywords.

Landing page experience: Google evaluates whether your landing page delivers on the promise of your ad. The page should be relevant to the keyword, load quickly, work well on mobile, and provide a good user experience. Match the landing page content to the ad and keyword intent.

Account structure matters: the campaign and ad group structure directly affects Quality Score. Single-theme ad groups (sometimes called single keyword ad groups or SKAGs) ensure tight relevance between keyword, ad, and landing page.

Negative keywords: adding negative keywords prevents your ads from showing for irrelevant searches. This improves click-through rate by eliminating impressions from people who will not click, which improves expected CTR.

The compounding effect: a Quality Score of 7 or above means you pay less per click than competitors with lower scores. Over time, the cost savings compound — you can afford more clicks, more conversions, and more growth from the same budget.
