Demystifying Google Ads: What is Quality Score and Why it Matters
For any business owner in India looking to grow online, Google Ads (often still referred to as Google Adwords) is a powerful tool. It allows your business to appear at the top of search results when potential customers are actively looking for products or services like yours.

If your ad is highly relevant and compelling, more people will click it. A higher expected CTR tells Google that your ad is a good match for what users are searching for, contributing positively to your Quality Score.
2. Ad Relevance
