# How to review TikTok Spark Ads against paid-only creative

> Tier: deep. Full contract: quantified decision rules and evidence requirements.

Whether boosted organic posts outperform studio creative on TikTok, with the organic joins that show what the boost actually bought.

**Intent.** Decide where Spark Ads earn their place in the mix, on numbers instead of platform folklore.

## When to use

- Spark Ads carry meaningful spend.
- Creator content strategy is being priced against studio production.
- Organic posts are performing and someone proposes boosting them.

## When not to use

- Accounts without Spark authorisation or organic presence: nothing to compare.
- Windows under 14 days: creative comparisons need stabilised delivery.

## Sources

Required: TikTok Ads

## Preconditions

- Spark Ads live or recently concluded on the ticked advertiser.

## Inputs

- `window`: Comparison window. Default: last 28 days.

## Procedure

1. List Spark Ads and their linked organic posts. — tools: `tiktok_get_spark_ads`
2. Join paid performance to the organic side of each post. — tools: `tiktok_get_spark_organic_joins`
3. Pull the comparable paid-only creatives' performance over the same window. — tools: `tiktok_get_insights`, `tiktok_get_creatives`
4. Compare on the account's KPI, at matched spend levels where possible.

## Decision rules

- **When** Spark Ads beat paid-only on CPA at comparable spend → **conclude** Scale candidate; name the creator/post pattern that wins, because the pattern is the asset.
- **When** Spark engagement is high but conversions lag paid-only → **conclude** Top-funnel value only: recommend it for reach objectives and say the conversion claim is unsupported.
- **When** One post dominates the Spark results → **conclude** Report concentration: the finding is that post, not the format.

## Evidence requirements

- Every comparison carries spend, KPI, window and delivery volumes on both sides.
- Organic-side effects quote the joins tool, not screenshots or lore.

## Human approval boundary

- Creator negotiations and boost authorisations are human; pausing or scaling Spark campaigns goes through Safe Writes.

## Failure modes

- Spark posts often get preferential engagement by design; engagement deltas are not efficiency deltas.
- Authorisation expiries kill Spark delivery silently mid-window; check delivery status before judging decline.
- Selection bias: only good organic posts get boosted, so Spark averages flatter the format.

## Output

- **The comparison**: Spark vs paid-only on the KPI, matched windows.
- **Winning patterns**: Post and creator patterns behind the wins.
- **Recommendation**: Where Spark earns its place, and at what share.
