How to evaluate a visitor identification vendor

By the Leafprint team at Gold Standard Solutions. Published October 31, 2026. General information, not legal advice.

Start with your own goal

Before speaking with any vendor, write down what you want to achieve. Understanding which channels bring local shoppers is one goal. Finding retail buyers for a brand is another. The right tool and the right test depend on which you pick, and a clear goal makes it harder for a good demo to distract you.

Questions about data

• Where does the match data come from? You may not get every provider name, but you should get a clear account of the types of sources and how they obtained the information.
• What fields can a match include? Ask for a sample profile with fake data, along with how often each field tends to be filled in for accounts like yours.
• How old can the data be? People move and change numbers. Ask how records get refreshed.
• Who has access to my data? Find out what happens to the visitor information your site generates, and whether it gets used for anything beyond your account.

Questions about match rates

Be skeptical of any single headline figure. A match rate depends on the audience, the site, and how the vendor defines a match. Ask how the number was calculated, whether it counts people or companies, and what it looked like for sites similar to yours. Then treat it as a claim to test, not a fact.

Also ask about accuracy, which is a separate question. A high match rate with many wrong matches is worth less than a lower rate you can trust. The way to find out is to check matches against customers you already know.

Questions about compliance

• Can matched phone numbers be used for text marketing? If the answer is an easy yes, be careful. A match is not written consent.
• What does the vendor claim about compliance? Words like “fully compliant” are hard to support, because compliance depends on your own use and your own state. Ask what specifically they mean.
• How do opt-outs and deletions work? Ask for the specific process, including how a request reaches the vendor and the data providers.
• What contract terms apply? Have counsel review terms and any data agreement, including who is responsible for what.
• Can they back up technical privacy claims? If a vendor describes its product with a technical term, ask for an explanation your counsel can check.

Questions specific to cannabis

Confirm the vendor will work with cannabis businesses at all, since some will not, and ask whether that could change. Ask whether anyone there understands the difference between state markets. A vendor who has never heard about carrier restrictions on cannabis texting may not spot the problems you are about to create.

Questions about operations

• How is pricing calculated? Get clear on what counts as a billable lead, and whether repeat visits by the same person are counted again.
• Can I control spending? Ask how limits work, and what happens during a traffic spike.
• How does data leave the system? Check for exports or webhooks, and make sure you can get your data out.
• What happens when I cancel? Ask about contract length, notice, and what happens to your data.

How to run a fair test

Pick a clear time period and one goal. Update your privacy policy before installing anything. Then evaluate on three things.

First, check quality: take a sample of matched profiles and compare them with customers or accounts you know about. Second, check usefulness: can you name a decision you made or changed because of this data? Third, check cost: divide what you spent by the useful outcomes, not by the number of profiles.

If you are testing more than one vendor, try to do it over a comparable period, and watch out for adding too many scripts at once. Be sure your privacy policy covers each one.

Compare the whole picture

Avoid choosing on price per lead alone. A cheaper lead that turns out to be wrong costs you staff time and creates risk, while a more expensive one that helps your team make a good decision may be a bargain. Write down your findings in the same format for every vendor, so that the most polished demo does not automatically win.

Red flags

• Guaranteed match rates with no explanation.
• Promises that the product removes any need for consent.
• Unwillingness to explain data sources in any form.
• No clear process for opt-outs.
• Pressure to sign before you have had a legal review.
