Paid Social
Paid social is the practice of running paid advertising on social media, where targeting uses user attributes and behavior rather than search intent. Platforms include the Meta family (Facebook and Instagram), TikTok, LinkedIn, X, Reddit, Pinterest, Snapchat, and YouTube, with targeting using attributes, interests, behavior, and lookalike audiences, and creative quality the dominant variable in performance. It is the demand-generation counterpart to paid search's demand-capture, and the channel where the platform algorithms have absorbed most of the optimization work that targeting and bidding once required.
The platform-by-use-case picture in 2025: Meta (Facebook and Instagram) is still the largest paid-social channel for most B2C and SMB advertisers, with broad reach and the most mature creative-driven optimization (Advantage+ campaigns); TikTok has become essential for consumer brands targeting under-35 audiences and rewards native-feeling, creator-style content; LinkedIn is the dominant B2B paid-social channel for professional and account-level targeting, with the highest CPCs ($5 to $15 range) but the highest-quality leads for enterprise software; YouTube (technically under Google) covers video at scale with strong intent signals via in-stream and Shorts; Reddit has become a meaningful channel for community-driven products and high-consideration B2B since its 2023 to 2024 ad-platform maturation; X and Snapchat are situational, valuable for specific verticals. The 2021 iOS 14.5 App Tracking Transparency change broke a lot of the cohort-level targeting Meta had relied on, which is why CPMs on Meta rose meaningfully and reported ROAS divergence from incremental ROAS widened. The lesson reinforced since: creative is the only durable lever. Targeting has been absorbed by algorithms, attribution has been blurred by privacy changes, and the only thing the advertiser still controls completely is the ad itself.
Ryan's Take
Paid social used to be a targeting game. It is now a creative game. The algorithm is better than you at finding the right audience; it is not better than you at making the audience care. Founders who treat paid social like a bid-and-target optimization problem in 2026 are fighting last decade's war. The startups winning at paid social today have a creative testing engine running 20 to 50 ads a week, killing the losers, and pouring spend behind the winners. The single biggest unlock is hiring or contracting an actual creative team, not optimizing budgets in Ads Manager at 2 AM.
What founders get wrong: Treating paid social like paid search. They are different motions. Search captures existing demand from people typing what they want; social interrupts a feed and creates demand. The ad copy, the offer, the landing page, and the success metrics should all be different. A search-style "request a demo" CTA on a cold social ad converts terribly; an educational top-of-funnel hook converts well, then gets retargeted with a request-a-demo follow-up.

FAQ
What is paid social?
The practice of running paid advertising on social media platforms (Meta, TikTok, LinkedIn, X, Reddit, Pinterest, Snapchat, YouTube), where targeting is based on user attributes, interests, behavior, and lookalike audiences rather than expressed search intent.
Which paid social platform should startups use?
Depends on audience. Meta (Facebook + Instagram) for B2C/SMB breadth. TikTok for under-35 consumer reach. LinkedIn for B2B and enterprise (highest CPCs at $5-$15 but highest-quality leads). YouTube for video at scale. Reddit for community-driven products and high-consideration B2B. Pick the platform where your audience pays attention.
Is paid social or paid search better?
Different jobs. Paid search captures existing demand (someone is typing what they want). Paid social creates demand (you interrupt a feed). Most startups need both eventually; if you can only pick one to start, pick the one that matches your buyer's behavior: search if they actively look, social if they don't know to.
