Based on the transaction process, we build an
analytical model about web marking applicability of
commodities in this paper, and use it in the analysis, then we
conclude that three index (abundance of commodities, concern
degree and conversion rate of transaction) can be used to
describe web marketing applicability of goods. Following this,
we apply the data of three typical products (search, experience
and trust categories) from Taobao and eBay for verification.
