Is MER the only metric that matters for video ads?
MER is not the only metric that matters for video ads. MER (total revenue divided by total marketing spend) is a company-level sanity check. It cannot diagnose a tired hook. Use MER so platform ROAS does not lie about the business; Use hook rate and hold rate so you know what to make next; eonik does not compute MER; It makes the next cut.
The steps
01
Calculate the Baseline
Pull your Total Gross Revenue for the last 30 days. Pull your Total Ad Spend across Meta, Google, and TikTok. Divide Revenue by Spend to find your baseline MER.
02
Change the Creative KPI
Instruct your media buyers to stop pausing Top-of-Funnel videos based on 1-day click ROAS. Shift their micro-KPI to "Cost Per 15-Second Video View."
03
Iterate on Engagement
If a video has a low Hook Rate, do not pause it. Use an assembly engine to programmatically swap the first 3 seconds, keeping the core body intact.
04
Monitor the Macro Trend
Scale the budget on the new variations and watch the overall MER. If total brand efficiency rises, the creative is working, regardless of what the platform dashboard claims.
Is MER the only metric that matters for video ads?
MER is not the only metric that matters for video ads. MER (total revenue divided by total marketing spend) is a company-level sanity check. It cannot diagnose a tired hook. Use MER so platform ROAS does not lie about the business; Use hook rate and hold rate so you know what to make next; eonik does not compute MER; It makes the next cut.
Two altitudes
MER asks: is marketing spend creating revenue at all? Video attention ratios ask: is this file still earning a start and a hold? You need both altitudes.
“Only MER” as a slogan hides creative fatigue until the P&L is already ugly.
Do this in order
Do not pick a religion. Pick a weekly order of operations.
- 1. Look at MER (or contribution) so platform ROAS cannot gaslight the board.
- 2. If MER slips, check whether top spenders’ hook rate slipped versus last week.
- 3. If attention slipped, make new openings in eonik before you rebuild the media mix.
- 4. You still own budget. eonik never reallocates it.
What the title is allowed to mean
The title is a provocation. The workflow uses both altitudes. MER without video columns is blind. Video columns without MER can win the auction and lose the company.
Omit invented healthy-MER league tables. Compare to yourself.
What usually breaks
- Optimizing only in-platform ROAS while MER collapses.
- Using MER alone and never opening video columns.
- Inventing a 2026 “healthy MER” league table.
When the readout is fatigue, hook rate, or velocity, the next move is consider what to make. Then make the cut in eonik and approve it. The loop is how to generate AI ads. It never touches spend.
“Almost any question can be answered, cheaply, quickly, and finally, by a test campaign. And that’s the way to answer them, not by arguments around a table.”
That principle still holds. The next on-brand cut is yours to approve.

Questions
Is MER the only metric that matters for video ads?
No. MER is the business check: total revenue divided by total marketing spend. It cannot diagnose a tired hook. Video ads still need hook rate and hold rate so you know what to make next; The title is a provocation; The workflow uses both altitudes; Use MER so platform ROAS does not lie; Use attention ratios so fatigue does not hide until the P&L is ugly.
Is MER really the only metric that matters?
No. It is the company-level sanity check. Creative still needs 3-second plays divided by impressions and ThruPlays divided by 3-second plays. If MER slips, check whether top spenders’ hook rate slipped versus last week; If attention slipped, make new openings before you rebuild the media mix; You still own budget; Do not invent a healthy-MER band.
Can eonik report MER?
No. Pull MER from your finance stack. Use eonik when the next action is a new ad: consider the opening, assemble the on-brand cut, approve, upload yourself. It does not reallocate budget and does not ingest the P&L; Two altitudes stay separate on purpose; MER tells you whether marketing spend is creating revenue; Attention ratios tell you which file to remake.
