What I know about foreign trade optimization is that many domestic promotion companies are mixed. Among them, the company with relatively high turnover in the market has Hangzhou foreign trade express; Ningbo's Global Connect, Xiamen's foreign trade cattle, Chengdu's global search.
My understanding of the comparison between these families (purely personal)
First, foreign trade express delivery is characterized by a large number of customers and a large income scale. The customer renewal rate is about 30%, starting at 40,000.
Second, Global Trade Link is characterized by many overseas links, stable technology, smaller market scale than foreign trade through trains, fewer offline service points, a renewal rate of less than 30%, and a start of 30,000.
Third, foreign trade cattle, optimization and bidding together, low technology, not real optimization, low update rate, starting price of 40 thousand, false propaganda.
Fourth, global search, the team comes from Global Tradelink, basically no product team, poor market reputation, and basically no renewal fee.
