Word of mouth is Amazon.com's most powerful customer acquisition tool.

This is a factual claim about Amazon.com's own business, judged as of 1997. True if Amazon's own records or credible contemporaneous analyses from 1996–1997 (customer surveys, filings, analyst reports) show that word of mouth or referrals was the leading source of new customers, ahead of paid advertising, portals and affiliates. Mostly true if word of mouth is shown to be a major source of new customers, roughly level with the top channel, but not clearly the single largest. Mixed if evidence shows it was one significant channel among several, with no clear ranking. Mostly false if available data show another channel (such as portal deals or paid advertising) brought in clearly more customers, while word of mouth was still meaningful. False if evidence shows word of mouth was a minor source of new customers. If the only evidence is Bezos's own assertion and nothing independent or quantitative bears on it, the claim stays unresolvable; it is not marked false on that ground.

The only direct support for word of mouth is an Amazon media relations director's statement, reported in a retrospective trade-press article with no customer-source figures (E1). That is a statement from within Amazon, not independent or quantitative evidence of customer sources. Amazon's 1997 filings and releases describe significant paid promotional deals with Yahoo, AOL and Excite that were expected to bring customer flow, and a placement deal with GeoCities (E2, E6, E7, E8). A reference profile says two of the most visited sites on the Web agreed to give Amazon broad promotional capabilities, and that the Associates program began to take off in mid-1997 when Amazon formed partnerships with Yahoo and AOL (E3, E5). None of these sources measures or ranks where new customers came from, so the evidence cannot show whether word of mouth was the leading channel.
