Collection using third-party crawler tools refers to the use of some third-party crawler tools to crawl and collect data on the Amazon platform. Compared with manual collection, crawler tools can quickly and efficiently collect data, thus saving a lot of time and energy. There are also many entry-level software, such as Octopus Collector, Houyi Collector, and Ivy Collector.
The advantages of third-party crawler tool collection are low technical barriers and high efficiency; the disadvantages are that the data needs to be cleaned later, and some collectors charge a fee when exporting data. Generally speaking, it takes about 0.5 seconds for a crawler tool to crawl a single piece of data on a first-level page, and there is almost no data error. In addition, the advantage of automated crawler programs lies in the ability to continuously crawl data, that is, 24-hour uninterrupted crawling. Considering that crawler tools will occupy a large amount of computer memory when collecting data, operators can crawl outside of working hours without taking up working hours.
