B2B marketplace listings

They pair two record types: product offers and seller profiles. IndiaMART's marketplace entry is tagged 'b2b marketplace, suppliers, product listings, seller directory' with an update frequency of realtime, and sized at 'tens of millions of live listings across ~200k+ supplier catalogs'.

Because updates flow continuously and nothing is archived, the corpus behaves like a living map of the supplier landscape rather than a time series. Category trees - industrial plants, machinery and supplies among them - organise both offers and sellers, so the same platform answers sourcing questions and market-structure questions.

Scale plus freshness makes them the fastest read on who supplies what. At tens of millions of listings across 200k+ supplier catalogs, category coverage gaps show up immediately - absence from the marketplace is commercially meaningful signal.

But collection legality is part of the evaluation. IndiaMART is explicitly described as a scrapeable map of supplier landscapes subject to its anti-scraping terms, and realtime update frequency means any collected copy decays quickly. Without a historical archive, longitudinal claims require the collector's own snapshots - a burden worth pricing before committing to a listing-derived product.

1. Size the corpus. Tens of millions of live listings across ~200k+ supplier catalogs is IndiaMART's scale - competitors should state equivalents.

1. Confirm update cadence. Realtime refresh means decay is fast; ask how recently any derived copy was captured.

1. Check both record types. Seller-directory attributes and product listings serve different analyses; coverage of each matters separately.

1. Read the anti-scraping terms first. Collection rights determine whether a listing-derived product is buildable at all.

1. Plan for missing history. With no archive, longitudinal studies need externally sourced snapshots.
