Declining Organic Social and a Prospecting ROAS Problem
Glowform is a DTC skincare brand with 38,000 Instagram followers, 12,000 TikTok followers, and 8,000 email subscribers. Organic reach has fallen 35% in six months, Instagram engagement rate is 1.2%, and average video completion is 8% against an internal target of 18%. Five posts per week are produced by one generalist; 40 user-generated assets exist but only 12 have been used. Paid social spends $60,000 per month: blended ROAS is 1.7, retargeting ROAS is 2.4, and prospecting ROAS is 1.1. Repeat customers drive 70% of revenue, while new-customer CAC has risen 28% year over year. The Q3 goal is to grow new-customer revenue by 20% without increasing CAC by more than 10%. The founder wants to double posting frequency and boost every post. The marketing lead has one month and a $15,000 incremental test budget. What should the team do?
1. Diagnose why organic engagement and paid ROAS are weak, and explain the role each channel should play.

The symptoms point to a content-market fit and funnel-role problem, not simply posting volume.
- Reach down 35% with 1.2% engagement suggests the account is reaching existing followers with content that does not earn saves, shares, or comments. An 8% video completion rate against an 18% target means hooks are weak or videos are too long; the first two or three seconds are failing.
- 40 UGC assets with only 12 used means the team is not testing the creative format most likely to feel native and credible. UGC often outperforms brand-produced content in prospecting because it looks like a recommendation, not an ad.
- Paid ROAS of 2.4 on retargeting versus 1.1 on prospecting is directionally normal, but a 1.1 prospecting ROAS may be below contribution margin after COGS and shipping. Retargeting harvests demand; prospecting must create it. Blended 1.7 hides that the business is underinvesting in demand creation or using the wrong creative.
- Organic social: prove which hooks, formats, and messages earn attention; feed top-performing organic concepts into paid; build community and UGC supply. Do not judge it on last-click ROAS.
- Paid prospecting: acquire new customers with UGC and testimonial creative; measure new-customer CAC and contribution, not blended ROAS.
- Retargeting: recover intent but cap frequency and exclude existing subscribers to avoid paying for repeat customers who would convert anyway.
- Email: convert and retain the 8,000 subscribers; use it to extend the life of social content.
2. Design a 30-day test matrix for the $15,000 incremental budget, with hypotheses, metrics, and decision rules.

Objective: find one prospecting creative angle that lowers new-customer CAC by at least 10% without hurting contribution margin.
| Test | Hypothesis | Budget | Primary metric | Decision rule |
|---|---|---|---|---|
| A. UGC hook test | Three UGC openings - problem, testimonial, demo - beat a brand-produced opening on 3-second view rate and CTR | $4,500 | 3-second view rate, CTR, CPC | Scale the winner if CTR is at least 20% above control and CPC is not higher |
| B. Length test | 15-second cutdowns improve completion and CAC versus 30-second versions | $3,000 | Completion rate, CAC | Keep shorter if completion rises and CAC falls or is flat |
| C. Creator whitelisting | Two mid-tier creators' handles improve trust and CTR versus the brand handle | $4,000 | CTR, CAC, comment sentiment | Continue only if CAC is within 10% of target and sentiment is neutral or positive |
| D. Landing page match | A message-matched landing page lifts conversion versus the home page | $2,000 | Landing page CVR, cost per purchase | Adopt if CVR lifts at least 15% |
| E. Retargeting frequency cap | Capping frequency at three per week keeps ROAS and reduces wasted spend | $1,500 | Frequency, ROAS, incremental purchases | Cap if ROAS holds within 5% |
Run tests A and B first because they answer the creative question fastest. Use 50/50 splits within the same campaign where possible. Do not judge on platform ROAS alone: reconcile purchases in Shopify and calculate new-customer CAC. Pre-register the decision rules; stop a test early only for a clear loss or a safety issue. Keep 20% of budget as a holdout to estimate incrementality.
3. The founder wants to double posting frequency and boost every post. How should the lead respond?
Read the worked answer
Acknowledge the instinct but separate volume from learning. Doubling from five to ten posts per week with one generalist likely lowers quality and increases production risk. Boosting every post spreads a fixed budget across weak creative and makes it impossible to tell what worked.
Propose a controlled alternative:
- Test frequency, do not assume it. Run a 30-day comparison of five versus eight posts per week, keeping production quality constant. Measure 3-second views, saves, shares, follower growth, and downstream new-customer CAC, not just likes.
- Boost only proven organic. Set a rule: boost posts that beat the account's median on saves or 3-second views, or that use a UGC hook already validated in paid. Use paid to amplify demand, not to rescue weak posts.
- Protect the organic role. Keep three to four organic posts per week focused on community, education, and UGC sourcing, plus two paid-led concepts. This gives the algorithm consistent signals without flooding the feed.
- Tie the decision to the Q3 goal. The goal is new-customer revenue with CAC within 10%. More posts only help if they improve qualified reach or creative learning. If the frequency test does not lower CAC, revert.
This response respects the founder's urgency while avoiding a budget-wide boost that would obscure results.
