The logic of keyword selection is to find products that are in the growth stage or have potential by capturing the product ASIN, listing date, ranking and other information under the search results of a common keyword (within 6 words) within a period of time, and analyzing the listing date and ranking fluctuations. Generally speaking, through more than 2 weeks of data collection, you can preliminarily judge whether the product has potential. At this time, you can purchase in small batches through 1688 or the supply chain. When the quality is confirmed to be 4 stars or above, send FBA and continue to optimize to create a hit.
The advantage of keyword selection is that it can be operated in batches, quickly find a large number of links in the rising period, and determine the direction of product advertising promotion in the later stage. The disadvantage is that the ranking of some products has changed greatly in the early stage, and the data has a certain delay. Not every ASIN’s daily ranking can be crawled. In addition, there are situations such as fake orders that interfere with the data, so further analysis is needed. Third-party collectors can use creeper collectors, octopus collectors, Houyi collectors, etc.
