Connect 2+ platforms in Wevion to launch from one form, analyze together, manage creatives in one library.

Working across multiple ad platforms

Wevion's value compounds when you run on multiple platforms. Bulk Launch spins up campaigns on Meta + Google + TikTok from one grid. Cross-Channel Analytics shows them side-by-side. Creative Hub stores assets once and reuses everywhere.

Who is this for

Mediabuyers managing 2+ ad platforms — typical scenarios: Meta + Google for performance, Meta + TikTok for reach + younger audiences, all platforms for big brand budgets.

What changes when you go multi-platform

Three things start working differently:

1. Launching at scale (Bulk Launch)

When you're on one platform, Campaign Creator (one-at-a-time launcher) is enough. When you're on 3 platforms running 30 campaigns / month, the same flow doesn't scale.

Bulk Launch at /launch is a spreadsheet-style grid, scoped to one platform at a time (the active platform). Each row = one campaign. Columns = the same fields you fill in Campaign Creator (ad account, objective, budget, audience, creative). Fill your rows, click Publish, and Wevion launches them row-by-row for that platform. Each wave targets one platform: to launch on another platform, switch the active platform and run another wave.

Common patterns:

  • Same product, different audience within a platform (one broad row, one age-specific row)
  • Multi-country: 1 row per country, launched as one wave for the active platform
  • To reuse the same creative on another platform, switch the active platform and run a second wave

2. Reading the numbers (Cross-Channel Analytics)

At /analytics (Cross-Channel mode), Wevion aggregates performance from all connected platforms. The default view has 5 narrative blocks:

  • KPI strip — total spend, conversions, ROAS, CPA across all platforms
  • Channel mix donut — how spend is distributed
  • Channel comparison matrix — same metrics per platform, side-by-side
  • Budget recommendation — AI-suggested rebalance based on observed ROAS
  • Top campaigns — cross-platform ranking

This is the view that answers "Should I shift budget from TikTok to Meta this month?" — questions that are invisible if you're toggling between native ad managers.

3. Reusing creatives

Creative Hub holds your assets centrally. The same video uploaded once can run on Meta, TikTok, and Snapchat with platform-appropriate aspect ratios (Wevion auto-crops on launch when source asset is high-res enough).

This sounds small but it removes 60% of the file-shuffling work for multi-platform teams.

How to get there

If you've connected one platform:

  1. Connect a second (see Connect your first ad platform — same flow)
  2. Wait 10-30 minutes for the initial sync of the new platform
  3. Open /analytics and use the Cross-Channel mode toggle to aggregate both platforms
  4. Try Bulk Launch with one cross-platform row (just to see the form)

After 7 days of running on both platforms you'll start seeing meaningful cross-channel insights.

Where platforms still differ

Wevion unifies management but not the underlying ad systems. Some things stay platform-specific:

TopicStays platform-specific
Ad specsEach platform has its own image/video specs, character limits, CTA options
AudiencesCustom audiences and lookalikes live per platform
PixelsEach platform has its own pixel; events not shared cross-platform
Bid strategiesEach platform offers different bid types (lowest cost, target ROAS, etc.)
Reporting attributionEach platform claims its own conversions; cross-channel deduplication is best-effort

Wevion does not hide these differences — Campaign Creator and Bulk Launch surface platform-specific fields when relevant.

Cross-channel attribution caveat

When Meta and Google both claim a conversion (often: Google search after Meta video view), Wevion's Cross-Channel Analytics deduplicates using the last-touch attribution as the default. This means total cross-channel conversions are usually 10-30% lower than the sum of per-platform conversion counts.

This is correct — you didn't get 2 conversions; you got 1 attributed differently by each platform. The Cross-Channel view shows the realistic number; per-platform views show each platform's claim. Use Cross-Channel for budget allocation decisions.

Common patterns by team size

Team sizeRecommended setup
Solo / Freelance1-2 platforms, Express mode in Campaign Creator, Single Platform mode in Analytics
Small team (2-5)2-3 platforms, Bulk Launch for scaled per-platform waves, Cross-Channel mode in Analytics
Agency / scaleAll 6 platforms, Bulk Launch + Rules for automation, RBAC roles per teammate, separate Workspace per client

What you'll see

A healthy multi-platform setup at day 7:

  • Each platform card on the dashboard shows recent spend
  • Cross-Channel mode at /analytics shows a balanced channel mix
  • Budget recommendation suggests data-backed rebalances
  • Creative Hub has at least 20-50 assets with reuse counts
  • Bulk Launch is open in a tab during launch days

Common issues

  • One platform dominates the cross-channel view: usually because the other(s) have very low spend. Cross-channel only becomes informative when each platform has at least 5-10% of total spend.
  • Cross-channel ROAS lower than per-platform ROAS: deduplication. See "Cross-channel attribution caveat" above.
  • Bulk Launch shows different fields per row: platforms have different required fields. Wevion shows only the fields applicable to each row's selected platform.
  • Creative auto-crop looks wrong: provide a source asset at higher resolution (4K for images, 1080p for videos) — Wevion can crop down but not up.

FAQ

How do I launch campaigns across multiple platforms at once?

Use Wevion's Bulk Launch at /launch, a spreadsheet-style grid scoped to one platform at a time. Each row is one campaign and columns are the same fields you fill in Campaign Creator (ad account, objective, budget, audience, creative). Fill your rows, click Publish, and Wevion launches them row-by-row for the active platform. To launch on another platform, switch the active platform and run a second wave.

Where can I compare platforms side-by-side in Wevion?

Open /analytics in Cross-Channel mode, which aggregates performance from all connected platforms into five narrative blocks: a KPI strip (total spend, conversions, ROAS, CPA), a channel mix donut, a channel comparison matrix, an AI budget recommendation, and a cross-platform top campaigns ranking. This is the view for deciding whether to shift budget between channels.

Why is my cross-channel ROAS lower than my per-platform ROAS?

Because Wevion deduplicates conversions. When Meta and Google both claim the same conversion, Cross-Channel Analytics applies last-touch attribution by default, so total cross-channel conversions are usually 10-30% lower than the sum of per-platform counts. This is correct — you got one conversion, not two — so use the Cross-Channel view for budget allocation decisions.

Can I reuse the same creative across multiple platforms?

Yes. Creative Hub stores your assets centrally, so one video uploaded once can run on Meta, TikTok, and Snapchat. Wevion auto-crops to platform-appropriate aspect ratios on launch when the source asset is high-resolution enough. Provide 4K images or 1080p video, since Wevion can crop down but not up.

What stays platform-specific even when I use Wevion?

Wevion unifies management but not the underlying ad systems. Ad specs, custom audiences and lookalikes, pixels, and bid strategies all remain per-platform, and each platform claims its own conversions with best-effort cross-channel deduplication. Wevion doesn't hide these differences — Campaign Creator and Bulk Launch surface platform-specific fields when relevant.
