Cookies are dead weight now, but creator attribution still needs a spine. Brands running six-figure influencer programs are discovering that identity-resolution match rates can swing reported ROI by 20 points or more depending on which vendor stitches the data together. So when marketing ops teams ask “Improvado or LayerFive,” they’re really asking: which one will actually find my customers?
That question matters more than it used to. With third-party cookies gone in most major browsers and walled gardens tightening data-sharing rules, the vendor you pick for identity resolution isn’t a backend detail anymore. It’s the difference between a creator program that gets funded next quarter and one that gets cut.
Why Match Rates Became the Metric That Matters
A few years ago, nobody outside a data engineering team cared about match rates. Attribution “worked” because cookies did the heavy lifting. Not anymore. Post-cookie identity resolution relies on probabilistic modeling, hashed emails, device graphs, and clean-room matching — and every one of those methods produces a different match rate depending on the vendor’s data partnerships and matching logic.
For creator marketing specifically, this is a bigger deal than for standard programmatic buys. Influencer-driven traffic tends to arrive through fragmented paths: a TikTok view, an Instagram Story swipe-up, a YouTube description link clicked three days later on a different device. Stitching that journey together without cookies requires serious identity infrastructure. Miss the match, and you undercount a creator’s real contribution — which means you either overpay for low performers or, worse, cut a creator who was actually driving conversions you just couldn’t see.
A 15-point gap in match rate between vendors can translate into six figures of misattributed creator spend for a mid-size DTC brand running twenty or more active partnerships.
Improvado vs LayerFive: What Each Platform Actually Does
Improvado built its reputation as a marketing data pipeline and reporting layer — pulling data from ad platforms, CRMs, and creator tools into a unified warehouse. Its identity resolution leans on a mix of deterministic matching (login-based IDs, hashed PII from CRM records) and integration-heavy stitching across dozens of pre-built connectors. It’s less a purpose-built identity engine and more a data unification layer that happens to include matching logic as part of its pipeline.
LayerFive, by contrast, was built specifically around identity resolution for post-cookie environments, with creator and affiliate attribution as a named use case. It leans harder into probabilistic modeling supplemented by first-party data onboarding, and it markets itself explicitly on match-rate performance rather than as a side feature of a broader reporting suite.
The distinction matters for buyers. If your primary pain point is fragmented reporting across fifteen martech tools, Improvado’s breadth is appealing. If your primary pain point is “I can’t tell which creator drove this conversion,” LayerFive’s narrower focus on identity stitching is the more direct fix.
Deterministic vs Probabilistic: The Core Trade-Off
Here’s the uncomfortable truth vendors don’t lead with: deterministic matching is more accurate but covers fewer users. Probabilistic matching covers more users but with more error. Improvado’s heavier deterministic weighting means higher-confidence matches on a smaller pool — often the customers already in your CRM. LayerFive’s probabilistic layer extends reach to net-new, anonymous creator-driven traffic, but at the cost of some match confidence.
Neither approach is “wrong.” They’re optimized for different problems. A brand with a mature CRM and heavy repeat-purchase behavior benefits from Improvado’s deterministic strength. A brand doing aggressive top-of-funnel creator seeding, where most traffic is net-new and anonymous, needs the reach that probabilistic modeling provides — which tilts toward LayerFive.
Match Rate Benchmarks: What the Numbers Actually Show
Public benchmarking on identity resolution vendors is thin, and both companies (like most in this space) publish selectively favorable case studies rather than third-party audited numbers. Treat any single vendor’s published match rate as a ceiling, not a guarantee, for your specific data environment.
That said, patterns from vendor documentation and practitioner reports point to a few consistent findings:
- Improvado tends to report match rates in the 60-75% range when CRM hygiene is strong and email hashing is consistent across systems — but drops meaningfully (often below 50%) for anonymous, first-touch creator traffic.
- LayerFive reports match rates closer to 70-85% for creator-attributed traffic specifically, driven by its probabilistic layer, but with wider confidence intervals and more reliance on modeled rather than confirmed identity.
- Both platforms see match rates fall sharply — sometimes 15-20 points — when a brand’s creator program spans multiple regions with different privacy regimes, since consent and data-sharing constraints vary.
The takeaway isn’t “LayerFive wins on paper.” It’s that the two vendors optimize for different traffic profiles, and your actual match rate will depend heavily on your own first-party data maturity, not just the vendor’s technology.
Don’t buy on a vendor’s published match rate. Buy on a match rate they can reproduce against a sample of your actual customer data during a pilot.
Where This Fits in the Bigger Identity-Resolution Landscape
Improvado and LayerFive aren’t operating in a vacuum. Brands evaluating post-cookie identity infrastructure are also comparing CTV-focused resolution vendors and CDP-adjacent platforms with overlapping capabilities. If you’re benchmarking beyond creator attribution specifically, it’s worth reviewing how CTV identity resolution vendors handle similar matching challenges, since many of the underlying data-partner relationships overlap.
It’s also worth asking whether you need a dedicated identity vendor at all, or whether your existing CDP infrastructure can absorb the workload with better configuration. For teams still deciding on architecture, our server-side attribution framework is a useful starting point before committing budget to either Improvado or LayerFive.
The CRM Data Quality Problem Nobody Wants to Own
Here’s the part vendors soft-pedal in sales calls: neither Improvado nor LayerFive can fix bad input data. If your CRM has inconsistent email formatting, duplicate records, or gaps in consent capture, your match rate will suffer regardless of vendor. This is why CRM signal quality has become its own evaluation category — see our breakdown of CRM signal fusion platforms for a sense of what “clean enough to match well” actually looks like in practice.
For brands running micro-influencer programs specifically, this problem compounds. Micro-creators often drive purchases through channels with minimal identity signal — DMs, comment-link clicks, referral codes typed manually at checkout. Our comparison of CRM-native tracking versus standalone tools covers how this affects vendor selection for smaller-scale creator programs, where match-rate economics look different than for macro-influencer campaigns.
How to Actually Evaluate These Two Before Signing
Skip the demo theater. Vendors will show you their best-case match rate on cleaned reference data. Instead, insist on a pilot using a sample of your real, messy customer records — the kind with typos, outdated emails, and inconsistent formatting that actually exist in production CRMs.
- Pull a stratified sample. Include recent CRM entries, older records, and known creator-driven conversions. Don’t cherry-pick your cleanest data.
- Run both vendors against identical inputs. Same sample, same timeframe, same success definition. Anything less makes the comparison meaningless.
- Score false positives, not just match rate. A high match rate with a high false-positive rate is worse than a modest match rate you can trust. Ask each vendor how they validate matches internally.
- Test regional variance. If you run creator campaigns in the EU, UK, or other regions with stricter consent regimes, test match rates separately by region. Aggregate numbers hide regional collapse.
- Check integration depth with your creator platforms. Match rate is meaningless if the platform can’t ingest your affiliate link data or UGC-tagged conversions in the first place.
This is also a good moment to loop in whoever owns budget approval workflows, since post-cookie attribution changes often require sign-off from finance and legal, not just marketing ops. Our piece on AI budget approval workflows covers how to avoid the internal delays that stall these evaluations for months.
The Compliance Angle You Can’t Skip
Identity resolution and privacy compliance are now the same conversation. Both Improvado and LayerFive rely on hashed or modeled identifiers, which reduces but doesn’t eliminate regulatory exposure. Brands still need documented consent trails, especially for EU audiences under ICO guidance and for US programs subject to FTC disclosure rules on influencer partnerships.
Ask both vendors directly how they handle consent revocation. If a customer opts out after a match has already been made, does the vendor purge the linkage retroactively? Not every platform handles this cleanly, and it’s the kind of gap that surfaces during an audit rather than a sales call.
Industry data from eMarketer continues to show marketers citing measurement accuracy as their top blocker to scaling creator budgets — identity resolution sits at the root of that problem, not on the periphery.
FAQs
Frequently Asked Questions
What is a good match rate for post-cookie creator attribution?
Most practitioners consider 65% or higher a workable baseline for creator attribution, though this varies by data maturity. Anything below 50% typically means you’re making budget decisions on incomplete data, which is risky for programs with significant spend concentrated in a handful of creators.
Is Improvado or LayerFive better for micro-influencer programs?
LayerFive’s probabilistic matching generally performs better for micro-influencer programs, since that traffic is often anonymous and first-touch. Improvado’s deterministic strength shines more with established customers and repeat-purchase audiences already sitting in your CRM.
Do these platforms replace a CDP?
No. Both function more as identity and data-unification layers that typically feed into or sit alongside a CDP, rather than replacing one outright. Brands evaluating full customer data infrastructure should assess CDP options separately.
How often should brands re-benchmark identity-resolution vendors?
Annually at minimum, and immediately after any major platform policy change (like a walled garden restricting API access) or a significant shift in your creator mix toward new channels.
Can match rates vary by social platform?
Yes, significantly. TikTok and Instagram-driven traffic often shows lower deterministic match rates than YouTube, where longer view sessions and more consistent login states improve identity signal quality.
Next step: run a side-by-side pilot with your own messy CRM data before signing either contract — the vendor that wins on a clean demo dataset is rarely the one that wins on your actual customer records.
