Half of local businesses in this Google Maps dataset have no website. Most TAM estimates built on web data probably miss them.
Hi,
Sharing something from a dataset analysis that affects how I think about local market sizing.
In a dataset of Google Maps local business listings across the US, roughly 50% have no website URL attached to their profile. This is across multiple categories and geographies, so it does not appear to be isolated to one vertical.
The downstream effect on market sizing is worth thinking about.
Most prospecting databases, enrichment tools, and lead generation platforms are built on the assumption that businesses have a domain. No domain means no record. That business simply does not appear in the dataset, not because it is inactive, but because the data pipeline has no entry point for it.
One implication: TAM estimates for local B2B markets that rely on web-based or domain-based data are likely undercounting the real number of operating businesses in a given category. The gap could be significant depending on the vertical.
A second implication: competition for reaching this segment through outreach is structurally lower, because most standard tools cannot even identify it. The friction is real, the contact data is harder to find, but the segment itself is not small.
None of this is a definitive claim based on this dataset alone. But the pattern is consistent enough to suggest that web-based data sources give an incomplete picture of local market size in the US.
