Understanding your first data — what to look at on day 1

Day 1 of a new campaign: check impressions, CTR, CPM — that's delivery health. Skip ROAS, CPA, conversion rate until you have 50+ conversion events. Optimizing on noise is worse than waiting.

Who is this for

Anyone who just launched their first campaign and is staring at the dashboard wondering what's normal and what's a problem.

The trap: optimizing too early

Most beginner mistakes happen in the first 24-72 hours. The platform needs to learn who responds to your ad. Decisions taken before that learning settles will usually hurt performance.

Two rules:

  1. Wait for 50+ conversion events before deciding to scale or kill on conversion metrics

  2. Wait for 1.000+ impressions per ad set before deciding anything on creative performance

If you don't have those volumes yet, the only valid action is to let the campaign run and check delivery is healthy.

Day 1 checklist (within 4 hours of activation)

1. Is the campaign delivering?

Open /ads-manager, find your campaign. After 1-2 hours of being Active you should see:

  • Impressions > 0 — the platform is showing your ads

  • Reach > 0 — to distinct people

  • Spend > 0 — budget is starting to move

If after 4 hours all three are still zero:

  • Creative still in review — wait. Most reviews complete within 24 hours

  • Budget too low for audience — increase daily budget by 50%

  • Targeting too narrow — broaden country or interests

  • Bid too low — only relevant in ABO with manual bids

2. Is the creative resonating?

The early signal is CTR (Click-Through Rate) = clicks ÷ impressions. Open the campaign drill-down to see CTR per ad.

CTR range

What it means

< 0.5%

Creative + audience are misaligned. Likely needs new creative

0.5% – 1.5%

Average. Acceptable but not a winner

1.5% – 3.0%

Good. Watch this one

> 3.0%

Strong creative. Scale candidate if conversion data confirms

Don't pause an ad on low CTR before 1.000 impressions — variance is too high.

3. Are you paying a reasonable price?

CPM (Cost Per Mille) = cost per 1.000 impressions. CPM tells you how competitive the auction is. Compare to typical ranges for your country + objective + platform — your industry's benchmark is what matters, not a universal number.

A CPM 2-3x higher than your industry benchmark on day 1 usually means:

  • Audience too narrow (raises auction price)

  • Targeting an over-saturated audience

  • Creative quality score is low (platforms reward better creatives with cheaper CPM)

Day 2-3: still about delivery, not conversions

By day 3 you should have:

  • A clear pattern of CTR per ad — kill the bottom 50% if you have at least 3 ads

  • Stable CPM (varies within ±20% day-to-day)

  • 10-30% of your daily budget spent each day (if not, budget is too high for your audience size)

You still don't have enough conversion data to act on ROAS/CPA — unless you're spending €500+/day on a high-converting audience.

Day 4-7: now look at conversions

Once you've accumulated 50+ conversion events, the conversion-driven metrics become meaningful:

Metric

What it tells you

CPA (Cost Per Acquisition)

What each conversion cost. Compare to your max-allowed CPA

ROAS (Return on Ad Spend)

Revenue ÷ spend. > 1.0 means profitable on the ad spend itself (ignoring fixed costs)

Conversion rate

Conversions ÷ clicks. Tells you about landing page + offer fit

Frequency

Avg impressions per person. > 3-4 starts to show fatigue

These are the metrics rules should target — see Your first automation rule for the scale/pause pattern.

Where the numbers come from

Wevion pulls performance data from each ad platform every 15 minutes. Conversion data is special — attribution windows on each platform can take 24-72 hours to fully settle:

  • Meta: 7-day click + 1-day view by default; conversions arriving up to 28 days for view-through

  • Google Ads: 30-day click default; some settle minutes after click, others later

  • TikTok: 7-day click + 1-day view

The dashboard shows the best-current-estimate. The same window viewed 48h later might show 10-30% more conversions due to late attribution. Don't kill a campaign on day-1 ROAS as if it were final.

Sync delay vs reality

Wevion's 15-minute sync means there's always a 0-15 min lag between an ad event and what you see. For most decisions this is negligible. For real-time monitoring during major launches, the dashboard's per-account refresh button forces a sync within 1-3 minutes.

Common day-1 questions

  • "Spend is much lower than my daily budget": normal in the first 12-24 hours. The platform paces conservatively while learning. By day 2-3 it should approach the cap.

  • "ROAS is 0": you have no conversions yet, or your pixel isn't firing purchase events. Verify the pixel is firing and that there's a Purchase event in last hour.

  • "CPA is €500 (impossible)": 1 conversion + €500 spend = €500 CPA. Sample-size problem. Wait for 50+ events before believing the number.

  • "Wevion shows different numbers than Meta Ads Manager": usually a timezone or attribution window mismatch. Wevion uses your workspace timezone; Meta defaults to Pacific Time.

  • "Should I A/B test creatives now?": yes — launch 3-5 ads in the same ad set, let them run 3-4 days, kill the bottom 50% by CTR.

What "good" looks like at end of week 1

A healthy first campaign at day 7:

  • Delivery stable (impressions and spend matching budget pace)

  • Best ad CTR settling above your platform's benchmark

  • 50-100+ conversions (if conversion-objective)

  • A clear pattern: 1-2 winners, 1-2 mediocre, 1-2 to pause

  • Frequency below 4 (otherwise time to refresh creative)

If you reach week 2 still with no clear winners, the creative or the audience usually needs to change — same budget on different angles often unblocks it.
