Google Display Network (GDN) reaches 90% of all internet users across 2 million websites, apps, and Google properties. While Display Ads have lower direct-response rates than Search (users are browsing, not searching), they excel at brand awareness, remarketing, and reaching large audiences at very low CPMs.
Display vs Search Ads
Search = pull marketing (user initiates, high intent, high CPC). Display = push marketing (you interrupt browsing, lower intent, low CPC/CPM). Display CPMs average $1–3 vs Search CPCs of $1–10+. Use Search for direct response, Display for awareness and remarketing.
Display Ad Formats
Responsive Display Ads (RDA — upload images and headlines, Google automatically generates ad variations), Static banner ads (JPG/PNG in standard sizes: 300×250, 728×90, 336×280), HTML5 animated ads, and Video ads on YouTube and GDN. RDAs are recommended for most advertisers.
Display Targeting Options
In-market audiences (actively researching relevant products), affinity audiences (broad interest-based), custom intent audiences (based on specific search terms and URLs visited), topic targeting (website categories), placement targeting (specific websites), and remarketing lists.
Display for Remarketing
Display remarketing is typically the highest-ROI use of the GDN. Show targeted ads to previous website visitors as they browse other sites. Remarketing display ads deliver 3–10x higher CTR than generic display prospecting because the audience already knows your brand.
