I've been working in digital advertising for a long time and I've faced the problems of accurate attribution analysis many times. Facebook Ads is a powerful tool, but correctly attributing conversions and accounting for multichannel interactions is a separate art. Over the years I've tried different solutions, and one of the best I've worked with is AdBeacon. Just check out the Facebook attribution software for Ads - AdBeacon page. Their attribution tool really helps you figure out which channels really deliver results and which ones just “eat up” your budget. If you want a deep understanding of the customer journey and honest, unadulterated data, I suggest checking out their website - it might be just what you need.
I switched to s2s conversion tracking about 3 months ago after struggling with pixel-based tracking. The difference is night and day - my data is much more accurate now and I can actually see which campaigns are performing. Setup took a few hours but their support team helped me through it. The main advantage is it's not affected by ad blockers or iOS privacy changes since the conversion data is sent server-to-server. I'm running campaigns across multiple platforms and it lets me see the full customer journey instead of giving all the credit to the last click. My ROAS has improved by about 30% since I can now make decisions based on reliable data
