CampaignCrafter – Craft Winning Ad Campaigns
CampaignCrafter is a collaborative creative platform built for Facebook advertisers and teams who want to streamline the ad production process. By integrating with Facebook's Marketing API, CampaignCrafter enables you to design, preview, and launch campaigns directly from a unified workspace. Manage your creative assets, collaborate with teammates, and push campaigns to Facebook—all without leaving the platform. From concept to conversion, CampaignCrafter helps you craft ads that perform.
Automated Bid Optimization
Set a target CPA or ROAS, and BidZen adjusts bids up or down in real time based on conversion likelihood per impression. No more manual bid testing.
Placement-Level Bidding
Different placements yield different conversion rates. BidZen bids higher on Instagram Stories if that's where your audience converts, and lower on Audience Network where performance lags.
Time-Of-Day Bidding
Automatically increase bids during your peak conversion hours and decrease bids during low-activity periods. BidZen learns your hourly conversion patterns from historical data.
Budget-Bid Coordination
BidZen ensures your daily budget is paced smoothly while maintaining bid aggressiveness. Avoid spending full budget in the first hour or leaving money on the table.
Core Modules
Real-Time Auction Signal Processing
BidZen subscribes to Facebook's Marketing API real-time feed (where available) for each ad set. We analyze auction competition metrics (e.g., estimated bid range, auction winner's bid) and conversion probability signals. Our algorithm then calculates a recommended bid adjustment and applies it via the API's bid_amount or bid_strategy fields, typically within seconds of an auction result.
Placement Bid Modifier
Using Marketing API's placement-specific performance breakdown, BidZen calculates a multiplier for each placement (Feed, Stories, Reels, Search, Audience Network). The multiplier is applied via bid_adjustments in the API. For example, if Stories converts at 2x the feed, BidZen sets a +100% bid modifier for Stories. All modifiers are updated daily based on rolling 7-day performance.
Target CPA Control Loop
BidZen implements a proportional-integral-derivative (PID) controller on top of Facebook's own bidding. It monitors the gap between actual CPA and target CPA every hour. If CPA exceeds target, the controller reduces bids incrementally; if CPA is below target, it increases bids to capture more volume. Changes are applied via API without pausing campaigns.
Bid Simulator
Before changing bids, use BidZen's simulator tool. It queries the Marketing API's bid simulation endpoint (where available) to estimate reach, impressions, and cost at different bid levels. You can preview the trade-off between volume and efficiency, then set your new bid with confidence.
About Us
BidZen was founded by a team of quantitative marketers and machine learning engineers who believed that Facebook's automated bidding could be vastly improved. We saw the same issue everywhere: advertisers either accepted Facebook's "black box" bids or spent hours manually tweaking without clear results.
We built BidZen to give advertisers a transparent, intelligent, and calm way to manage bids. Our algorithms are designed to be conservative when uncertain and aggressive when data supports it. The result is less stress, better efficiency, and more time for strategy.
