Introduction
Ad extensions are a powerful yet often underutilized feature in Google Ads. They add extra information to your ad — like phone numbers, location, links, or special offers — improving visibility, click-through rate (CTR), and ultimately conversions.
When crafted properly, high-converting Google Ads extensions can make the difference between a standard ad and a campaign that delivers measurable ROI.
