Currently piloting the following personalized advertising formats:

• Geo-Personalization Extended to Image Ads (US only): In addition to the use of dynamic city and neighborhood names in ad copy, brands can now elect to automatically plug-in neighborhood or city names directly in their images, Spotlight ad creatives, and in-feed ads on Nextdoor to drive increased local relevance at the neighborhood level across the country. Geo-personalization allows advertisers to connect with neighbors in contextually relevant, hyper-local ways, with advertisers already seeing geo-personalization drive increased engagement in ad copy.
• Weather Targeting (US only): contextual weather targeting to reach neighbors with more relevance allows advertisers to provide the right message at the most relevant time, enabling brands to align campaigns with local, real-time conditions. With three new options for temperature-based targeting (Cold: 40-50F / Moderate: 50-80F / Hot: 80-100F), selecting these will target your ads (ex. promoting hot beverages during cold temperatures) to neighbors whose locations fall into these temperature ranges.

These innovations deliver a powerful dual value proposition: advertisers gain enhanced efficiency, creative flexibility, and superior results with neighborhood-level precision, while neighbors experience more useful, relevant ads that reflect their everyday local context. By combining Nextdoor’s unique neighborhood-level trust and engagement with advanced AI capabilities, these solutions transform local relevance into measurable business impact, directly addressing advertiser demands for richer storytelling formats, contextual real-time relevance, and AI-powered efficiency at scale.
