🧒 Explain Like I'm 5
Think of yourself as a teacher grading essays. Each essay is judged on how well it answers the question, how engaging and clear it is, and whether it follows the rules like proper grammar and formatting. In digital advertising, Quality Score is like that teacher's grade for your ad. Search engines, such as Google, evaluate your ad based on its relevance to the keywords you're targeting, how informative and appealing it is, and the experience users have when they click through to your site. If your ad is like a top-notch essay—informative, relevant, and easy to navigate—it earns a high Quality Score. Why does this matter? Just as a student with high grades might get into a prestigious college or earn a scholarship, a high Quality Score can secure better ad placements at lower costs. For a startup, this means you can maximize your advertising budget and reach more potential customers without overspending.
