Submit to data aggregators (Acxiom, Neustar, Infogroup)

Data aggregators occupy a structurally different and higher-leverage position than individual directory submissions, since these platforms feed business data to numerous downstream directories and services automatically — getting your information correct at this aggregator level has an amplified effect, propagating accurate data to many secondary sources that draw from these aggregators rather than requiring individual submission to each downstream source separately.

The practical implication of this amplified effect cuts both ways and deserves real attention — an error submitted to a major aggregator doesn't stay contained to that single platform, but potentially propagates to every downstream directory that draws from it, meaning the accuracy discipline established through your NAP data sheet is particularly critical for this specific submission category.

The propagation timeline for aggregator data reaching downstream directories is genuinely not instantaneous — some downstream directories update from aggregator data on their own periodic schedule, meaning the full effect of an aggregator submission may take real time, sometimes weeks, to become visible across every platform that eventually draws from it, and this delay is normal rather than a sign the submission failed.

This mission represents genuine leverage within the broader citation-building strategy — the relatively modest effort of submitting accurately to the major aggregators produces outsized downstream effect compared to the same time invested in individual, one-off directory submissions, making this a particularly high-value use of citation-building effort.
