Conversion API to every major platform
Server-side CAPI to Meta, Google (Enhanced Conversions), LinkedIn, TikTok, Microsoft, and Reddit. Cookies, ad blockers, and iOS tracking limits don't break the signal.

What you actually get
“Great” match quality.
Real buyers, not form-fillers.
“Great” match quality on Meta
Meta rates conversion-data quality on a scale from Poor to Great. Cometly enriches every event with IP, user agent, fingerprint, and hashed PII, so Meta's optimization algorithm trains on signal, not noise.
Optimize on the event that actually pays
Switch campaigns from “trial start” to “converted trial” or “demo attended.” We routinely see ads at higher cost-per-lead drive more closed deals than cheap top-of-funnel ones, because cost per lead lies and cost per qualified outcome doesn't.
Audience export, not just inputs
Slice any report by source, region, or stage, then export the contact list and push it into Meta or LinkedIn as a custom audience or lookalike seed.
Built-in Ads Manager
Toggle Meta ads on/off, adjust Meta budgets, and view full-funnel performance per campaign / ad set / ad from one screen. Google budget control isn't supported yet, and we'll be honest about that.
OAuth in, ready by the end of onboarding
Connect ad accounts with a few clicks. For Meta and TikTok, events are created automatically. For Google, LinkedIn, and Microsoft, you create the conversion action in the ad platform and map it in Cometly.
Per-event rules
Choose how every event hits Meta.
Per event.
Most Conversion API tools ship one global setting and call it done. Cometly lets you set rules at the event level: which events fire, when they fire, and whether you optimize for match quality or raw volume. No other Conversion API gives you this level of control inside one account.
- Only send attributed eventsRecommended for purchase, demo, and SQL events. Only events Cometly can attribute to a Meta click are sent, with parameters like fbclid intact. Match quality typically lands between 8.0 and 9.3 in Meta Events Manager.
- Send all eventsSends every occurrence regardless of attribution. Higher volume, lower match quality. Useful for top-of-funnel events where Meta benefits from raw signal.
- Do not sendMutes the event entirely. Use it for events the Meta Pixel already covers (like page views) so you never double-feed Meta with the same signal twice.
- Mix and match per eventSet Purchase to attributed-only, Trial Start to send-all, and Page View to do-not-send in the same account. One global default, fully overridable per event.

Ad platform optimization: CAPI, match quality, and offline wins.
Which conversion actions to optimize on, mapping CRM stages to Meta/Google, and dedup with legacy pixels. Book a call and we'll pressure-test your signal plan.
Talk to salesWhat does “match quality” actually mean?
Meta scores the conversion data you send through its Conversion API on five tiers: Poor, Okay, Good, Very Good, and Great. The higher the score, the better Meta's optimization can find lookalike buyers. Cometly enriches every event with IP, user agent, fingerprint, and SHA-256 hashed email and phone so events land in the top tier.
Does this replace the Meta Pixel?
No. The Meta Pixel keeps capturing browser-side events on your site, and Cometly sends the matching server-side events to that same Pixel through Meta's Conversion API. Meta automatically deduplicates the browser and server events using shared identifiers, so nothing is double-counted. One important note: Meta only allows one active Conversion API integration per Pixel, so Cometly becomes the CAPI for that Pixel.
Can I optimize on offline events like closed-won deals?
Yes. Cometly pulls deal data from HubSpot or Salesforce and sends it back to Meta as Conversion API events and to Google as offline conversion uploads. You can choose to send all events (higher volume) or only attributed events (higher match quality).
How long does setup take?
For Meta and TikTok, event creation is automatic once you OAuth in. For Google, LinkedIn, and Microsoft, you create the conversion action in the ad platform first, then map it inside Cometly. Most teams have CAPI live during their onboarding call.
Will this break our existing tracking?
No. Cometly runs alongside your Meta Pixel and Google Tag Manager setups and dedupes events using shared identifiers, so you don't double-count conversions. The Cometly Ads Manager becomes the source of truth for cross-platform reporting.
