San Francisco, USA

In-house team

Conversion is a performance social ads agency headquartered in San Francisco, serving DTC, B2B, SaaS, and app brands across the US, Canada, UK, and Australia. We've managed paid social spend for 200+ brands since 2018 — Meta, TikTok, LinkedIn, Pinterest, Snapchat, YouTube, and AppLovin — and we're a Meta Business Partner and TikTok Marketing Partner.

We don't sell media buying detached from creative. Our in-house studio produces 30–50 ad variants per month per scaled account — UGC, motion, founder-led, and AI-assisted concepts — fed directly into the buy. Reporting is anchored on contribution margin and MER, not platform ROAS. The number on your P&L is the only one we care about.

Tired of agencies that scale spend but tank contribution margin?

Why most paid social fails

Spend isn't a strategy. Creative is.

We've audited 200+ paid social setups in the last three years. The same three problems show up in nearly every account that's plateaued.

Creative starvation

5–10 ads in rotation, refreshed once a quarter. Meta and TikTok algorithms reward creative velocity — the winners are the accounts shipping 30+ variants per month. Most agencies don't have the in-house production to keep up.

Platform ROAS theater

Reporting anchored to inflated platform ROAS that doesn't reconcile with the P&L. Post-iOS 14 attribution drift, view-through windows, and double-counted conversions hide what's actually working. We instrument MER and incrementality from day one.

No post-click discipline

Great ads dumped onto generic landing pages. Mobile experience untested. Page speed in the red. Form fields too long. CRO and ads run as separate teams. We treat the ad and the page as one funnel — because that's how the user sees them.

Paid social services

Every platform, every motion — run by specialists

Full-service paid social media advertising — strategy, creative, media buying, attribution, and post-click CRO. We work in Meta Ads Manager, TikTok Ads Manager, LinkedIn Campaign Manager, Pinterest Ads, Snap Ads, Google Ads (YouTube), and AppLovin AppDiscovery.

Meta Ads (Facebook + Instagram)

Full-funnel Meta strategy — Advantage+ shopping campaigns, manual scaling structures, audience and offer testing, retargeting, dynamic product ads, and shop integrations. CAPI server-side tracking on every account.

  • Advantage+ + manual scaling
  • Catalog + DPA / DABA
  • CAPI + Conversions API

TikTok Ads

Native TikTok creative strategy — spark ads, branded content, TopView, Smart Performance, and TikTok Shop integration. Built around creator partnerships and the platform's algorithmic preference for in-feed authenticity.

  • Spark Ads + creator whitelisting
  • Smart Performance Campaigns
  • TikTok Shop integration
  • Events API + signal optimization

LinkedIn Ads (B2B)

B2B paid social on LinkedIn — sponsored content, message ads, conversation ads, document ads, and lead gen forms. Built for high-AOV B2B SaaS, services, and enterprise sales motions where pipeline quality matters more than volume.

  • Sponsored content + lead gen
  • ABM list targeting
  • Document + conversation ads
  • Insight Tag + offline conversions

Pinterest Ads

Performance Pinterest for visual-first DTC, home, beauty, fashion, and food brands. Idea pins, shopping ads, dynamic retargeting, and the conversion API for accurate attribution past iOS 14.

  • Shopping + standard ads
  • Idea pins + video ads
  • Conversion API integration
  • Catalog + DPA equivalents

Snapchat & YouTube Ads

Snap for younger DTC audiences and AR-led brands. YouTube for educational, demo-heavy, and consideration-stage funnels — Performance Max, video action campaigns, and brand-lift studies for the upper funnel.

  • Snap Ads + AR Lenses
  • YouTube Performance Max
  • Video action campaigns
  • Brand-lift + reach studies

AppLovin & App Install

App growth on AppLovin AppDiscovery, TikTok, Meta, and Apple Search Ads. SKAdNetwork-aware bidding, MMP integration (Adjust, AppsFlyer), and creative built specifically for app-install and in-app purchase optimization.

  • AppLovin AppDiscovery
  • SKAd 4.0-aware bidding
  • MMP + postback debugging
  • Apple Search Ads + ASO loop

Creative Production & UGC

In-house creative studio: static, motion, UGC, founder-led, and AI-assisted ad creative built for the platform. 30–50 variants per month per scaled account, briefed against creative hypothesis docs, not vibes.

  • Static + motion + UGC
  • Founder-led + creator briefs
  • AI-assisted variant production
  • Hypothesis-driven briefs

Attribution & Measurement

Server-side tracking (CAPI, TikTok Events API, LinkedIn Insight Tag), GA4 + GTM server containers, MMM-lite, geo-holdout incrementality tests, and post-purchase surveys. We tell you what's actually working — not what the platform claims.

  • Server-side conversions API
  • GA4 + GTM server containers
  • Geo-holdout incrementality
  • Post-purchase attribution surveys

Landing Pages & Post-Click CRO

Custom lead-gen and ecommerce landing pages, A/B testing harness, mobile speed optimization, and form/funnel CRO. Because the ad and the page are one funnel — and a great ad on a slow page is a wasted impression.

  • Custom landing pages
  • A/B testing (Convert, VWO)
  • Mobile speed + Core Web Vitals
  • Form + checkout CRO

Our paid social process

From audit to scale in 90 days

Conversion's four-stage growth process visualized in brand blue and green
01

Audit & strategy

Account audit, creative audit, attribution audit, and competitive teardown. We surface the bottlenecks (creative, audience, offer, post-click) and set a ROAS / MER lift target — not just deliverables.

02

Creative + funnel build

Brief and produce 20–30 launch variants. Build server-side tracking (CAPI / Events API), landing pages, and the post-click funnel. Reset campaign architecture for clean signal capture.

03

Test, learn, scale

Daily optimization, weekly creative drops, and bi-weekly strategic reviews. We isolate winning creative angles, audiences, and offers — then scale aggressively where the data signs off.

04

Compound the wins

Quarterly incrementality tests, MMM-lite reviews, and creative hypothesis refreshes keep the account compounding. We don't ride one winner — we build a creative engine.

Why Conversion

We're not a media buying shop. We're a creative + buying engine.

Meta Business Partner & TikTok Marketing Partner

Direct rep escalation, beta access to new ad formats, and platform-side support that takes weeks to get otherwise. Your account benefits from the platform's roadmap before it ships publicly.

Creative-first, not bid-first

Most accounts that have plateaued are creative-bottlenecked, not targeting-bottlenecked. We invest in creative throughput before we invest in bid theater. 30–50 variants per month, briefed against creative hypotheses.

In-house US team — no offshore subcontracting

Strategists, media buyers, performance creatives, motion designers, UGC producers, and analysts work in one room from our San Francisco HQ. Fewer handoffs, faster iteration, better outcomes.

Pay on results — for growth work

Skip the flat retainer. Move into our pay-on-results growth retainer where fees scale with incremental revenue lift. Aligned incentives. No upfront commitment. Cancel anytime.

MER and contribution margin, not platform ROAS

We instrument server-side tracking, geo-holdouts, and post-purchase surveys. Reporting anchors to the P&L number — not the inflated platform ROAS that lies after iOS 14 and view-through inflation.

One team for ads + landing pages + CRO

Brands that separate ad agency and CRO leave 30%+ on the table. We treat the ad and the page as one funnel and own the entire post-click experience — landing pages, A/B testing, mobile speed.

Frequently asked

Paid social questions

What does a social ads marketing agency do?
A social ads marketing agency plans, buys, creates, and scales paid advertising on social platforms — Meta (Facebook + Instagram), TikTok, LinkedIn, Pinterest, Snapchat, YouTube, and emerging networks. That covers strategy, audience and offer testing, creative production (static, video, UGC, motion), media buying, attribution and analytics, and continuous CRO on landing pages and funnels. A senior agency owns the full revenue path — not just the ad account.
How much does a social ads agency cost in the USA?
In the US market, social ads management fees typically run $3K–$15K per month for SMB and DTC brands ($20K–$200K monthly ad spend), and $15K–$50K+ per month for enterprise brands ($200K+ monthly spend). Most agencies bill management as a flat retainer or as a percentage of ad spend (8–15%). Conversion offers a pay-on-results model where fees are tied to incremental revenue lift — not a flat retainer.
Which platforms should my brand advertise on?
Depends on audience, product, and creative motion. DTC ecommerce: start with Meta + TikTok, layer Pinterest if female-skewing or visual-first. B2B / SaaS: LinkedIn + Meta retargeting + YouTube. Apps: TikTok + AppLovin + Meta. Healthcare and regulated: LinkedIn + carefully scoped Meta. We don't run every platform on every account — we pick based on data, not retainer maximization.
How long until I see results from paid social?
Creative testing windows are 7–14 days per concept. Most accounts see meaningful CPA or ROAS movement in week 3–4 after launch, and a stable scaling curve by month 2–3 once we've isolated winning creative angles, audiences, and offers. Brands that come in with strong product-market fit and existing review velocity scale faster — usually 30 days to first inflection.
What is the difference between social media marketing and paid social ads?
Social media marketing is broad: organic content, community management, influencer partnerships, organic SEO on social platforms. Paid social ads is the performance discipline — buying placements on Meta, TikTok, LinkedIn, Pinterest, Snapchat, and YouTube, optimizing for CPA, ROAS, MER, and contribution margin. The two should be coordinated, but they're separate skills. We do paid social. We coordinate with your organic and influencer teams.
Do you create the ad creative or just buy media?
Both. We have an in-house creative studio that produces 30–50 ad variants per month per scaled account — static, motion, UGC, founder-led, and AI-assisted concepts. The creative-to-media-buying loop is where ROAS is won or lost. Agencies that only buy media and outsource creative cap out fast.
What metrics do you optimize for?
Contribution margin first, MER (Marketing Efficiency Ratio) second, blended CAC third — never platform ROAS in isolation. Platform ROAS lies because of attribution drift, view-through inflation, and post-iOS 14 signal loss. We instrument server-side tracking (CAPI, TikTok Events API, LinkedIn Insight Tag), incrementality testing, and post-purchase surveys. The number on your P&L is the only one that matters.
Should I hire a freelancer, in-house team, or social ads agency?
Freelancers fit early-stage brands under $20K/month spend with a single platform and simple creative. In-house works once you're past $200K/month spend and can support 2–3 buyers + 3–5 creatives + an analyst. Agencies are right when you need creative volume, multi-platform expertise, and senior strategy without the headcount cost — typically $20K–$200K monthly spend or fast-scaling stages where speed matters more than equity.
How do I choose a paid social agency in the USA?
Look for: Meta Business Partner and TikTok Marketing Partner status, in-house creative team (not subcontracted), case studies with revenue metrics (not vanity follower counts), transparent reporting on contribution margin and MER, a documented creative testing framework, and at least 3 references in your stage of growth. Ask for a sample weekly report. We'll send ours.
Do you handle landing pages and post-click CRO too?
Yes. Paid social is half the equation — the landing page and post-click experience is the other half. We build dedicated lead-gen and ecommerce landing pages, run continuous A/B tests, and instrument analytics so we know which ad and which page combination is actually printing money. Brands that separate ad agency and CRO usually leave 30%+ on the table.
Can you scale my account past $1M/month in ad spend?
Yes. Most of our scaled accounts sit between $200K and $2M monthly spend. Past $1M/month the constraint stops being targeting and starts being creative throughput, attribution accuracy, and incrementality discipline. We've built creative pipelines that produce 50+ tested variants per month, and we run quarterly geo-holdout incrementality tests so the spend stays profitable.
Do you work with apps, ecommerce, B2B, and healthcare?
Yes — but we don't pretend we're equally great at all of them. Our deepest experience is DTC ecommerce on Meta + TikTok, app install on TikTok + AppLovin, and B2B SaaS on LinkedIn + retargeting. Healthcare and regulated verticals require specialized landing pages and compliance review — we run that work, but we'll tell you upfront where our edge is sharpest.
Are you a Meta Business Partner and TikTok Marketing Partner?
Yes — we hold Meta Business Partner status and are a TikTok Marketing Partner. That gives us beta access to new ad formats, direct rep escalation paths, and platform-side support that takes weeks to get otherwise. For LinkedIn we work with senior in-house buyers; for Pinterest we hold a Pinterest Partner badge.
What's your reporting cadence?
Weekly written report (Mondays) covering MER, CAC, contribution margin, creative winners and losers, and the next week's test plan. Monthly executive deck with strategic narrative, incrementality results, and recommended budget reallocation. Real-time Looker Studio dashboard you can check anytime. No 47-tab spreadsheets.
