Reddit tests ads in search results as Google's AI search cuts its traffic

Reddit brings advertising to search

Reddit said on Tuesday that it has started testing advertisements within its search results pages, opening one of the platform's remaining ad-free surfaces to marketers. According to TechCrunch, the test is limited to a select group of eligible advertisers, with placements chosen based on factors such as how relevant they are to a user's query. The company said it will study how people respond in order to refine the experience for both users and advertisers over time.

The examples Reddit gave are shopping-oriented: searching for an "espresso station" might surface promotions for espresso machines, coffee or mugs, while a query about a "home office setup" could return ads for monitors, desks and office chairs. The Verge notes that these placements join an already sizable ad operation — Reddit currently runs ads in its feeds in formats including images, videos, sponsored posts and AMAs, as well as within comment threads.

The test follows a rough earnings report

The timing is not accidental. As TechCrunch reports, Reddit beat Wall Street's estimates for revenue and earnings per share in its most recent quarter, yet its stock still fell after the company forecast fourth-quarter sales of $1 billion to $1.03 billion, short of the roughly $1.05 billion analysts had expected. Reddit attributed the weakness to declining search referrals from Google, whose AI-powered search experience — including its AI Mode — answers questions directly on the results page and sends fewer clicks to outside websites.

User numbers point the same way. TechCrunch reports that global daily active users were flat quarter over quarter at 130.3 million, while U.S. daily active users slipped from 53.2 million in the second quarter to 50.7 million, down 2 percent year over year. The company cautioned that if the trend continues, daily active users could fall by a low double-digit percentage in the fourth quarter.

That combination — stalled user growth and less free traffic from Google — explains why Reddit is now working harder to extract revenue from the users it already has.

Search ads are part of a larger pivot

During the same earnings announcement, Reddit also said it plans to shift toward a logged-in-only experience, rolling the change out gradually and starting in markets outside the United States. TechCrunch outlines two motivations: the move makes it harder for AI systems to scrape Reddit's content without permission, and logged-in users are worth more to advertisers because their activity provides richer signals about interests and behavior, enabling better-targeted and more profitable ads.

The Verge reports that the logged-in plan contributed to a 29 percent drop in Reddit's stock, and it arrives alongside several other recent changes to the platform, including new Following and For You feeds and tighter limits on who can access "Old Reddit."

Why it matters

For users, search ads push commercial content into a part of Reddit that previously felt closer to organic community knowledge, and the test signals a broader redesign of the platform around monetizable, logged-in sessions. For advertisers, query-based placements are attractive because they capture people at a moment of high intent — someone searching for an espresso machine is presumably in the market for one. More broadly, the move is a case study in how AI search is rewiring the economics of the web: when Google stops sending clicks to other sites, platforms like Reddit respond by squeezing more revenue from the audience that remains, and by putting their content behind a login.
