Expectation Setting
What counts as a good match rate for visitor identification?
The short answer
There is no single magic match rate, because it depends on your traffic and your region. Company-level identification on healthy B2B traffic resolves a meaningful share of visitors. Person-level is lower and varies more. Be sceptical of any vendor quoting one universal high percentage, because match rate is specific to your audience, not theirs.
Match rate is simply the share of your visitors a tool can put a name to. It sounds like it should be one fixed number. It is not, and here is why.
What moves your match rate
Your traffic mix moves it
A site visited mostly by businesses resolves better than one with lots of consumer or mobile traffic, which is harder to tie to a company.
Your region moves it
Company-level identification is available widely. Person-level is mostly a US and Canada story, so a UK-heavy site will see lower person-level numbers by design, not by fault.
Bots and noise drag it down
A chunk of raw traffic is not real buyers at all, and no honest tool counts that.
The number of data sources moves it
A single-source tool can only match the visitors in its own data, so its match rate is capped by one provider's coverage.
The honest catch: anyone who tells you a flat number like “we identify 70 percent” before seeing your site is guessing or selling. The only match rate that means anything is the one you measure on your own traffic over a couple of weeks.
So the better question is not “what is a good match rate.” It is “how much of my real, business traffic can this tool identify, and is that enough to be worth it.” Our guide to choosing visitor identification software walks through how to run that test, and the comparison of the leading tools covers why a multi-provider approach lifts coverage.
