Campaign Creation

From a single prompt to
a live campaign

Tell YEpsilon what you’re trying to achieve. A full campaign — built from your personas, ready for your approval — comes back in one conversation.

You review. You approve. I deploy directly to Google Ads, LinkedIn Ads, or Meta — no agency, no manual setup, no 47-tab spreadsheet.

Conversational brief — describe your goal, I handle the technical build
Real search volume and CPC data — so your keyword strategy reflects actual market demand
Multi-persona ad groups — each audience segment gets its own optimized copy
Request Changes loop — refine until you’re satisfied, then one click to go live

ROAS Optimization

I optimize every
6 hours while you sleep

Every 6 hours, your campaigns get better. What’s bleeding budget gets cut. What’s compounding ROAS gets more. Budget shifts to wherever it’s working hardest — automatically.

Every action is logged with a reason. Every high-impact decision goes through a tiered approval system — auto-approve low-risk moves, flag high-risk ones for your review.

Spend safety monitor — daily cap enforcement so you never overspend
Tiered approval — conservative, balanced, aggressive, or monitor-only mode

Ad Creative Studio

Creative that gets better
on its own

Every campaign launches with multiple creative variants. The ones that work get more run. The ones that don’t get replaced — before your team has to notice.

Before your ads start to tire, fresh creative is already in rotation. Each audience gets messaging built around what actually made them convert — not what performed best on average.
