In our daily Amazon operation work, we often need to crawl the ASINs of the top 50 BSR or search results pages for the positioning of advertisements or the reverse check of ASIN keywords.
- FIRST OPEN AN AI TOOL, WHICH IS USED IN THIS CASE, AND OPEN THE WEB PAGE https://kimi.moonshot.cn/
- There is a very useful tool in KIMI, a prompt word expert, and friends who can't write prompt words can directly use this tool to generate prompt words
3. Because we want to write regular expressions, I directly ask the prompt word expert to generate the prompt words of the computer programming master
4. Open the conversation and paste the above prompt into the dialog box
5.AI understand the persona, make a clear request for input, such as "Write a regular expression for extracting the ASIN of the Amazon page, the ASIN starts with the letter B as a 10-digit number"
6. Get a regular expression: \bB[A-Z0-9]{9}\b
7. For example, if I want to grab the current 50 ASINs in the subcategory of Men Walking Shoes, open the category leaderboard page:
https://www.amazon.com/gp/bestsellers/fashion/679303011/ref=pd_zg_hrsr_fashion
8. Right-click on the page, select the View Web Source Code menu item, press Ctrl + A to select all the source code, and then Ctrl + C to copy the source code.
9. Open the web page https://uutool.cn/extract-regexp/, paste the regular expression obtained above in the matching rules: \bB[A-Z0-9]{9}\b, select deduplication, and then put the copied source code in the main box, click to start processing, and get the desired ASIN,
注意忽略最后2个ASIN，这2个ASIN是亚马逊Amazon Secured Card和Amazon Business American Express Card的ASIN
10. In the same way, if you want to extract the page BSR51-100, you can open the page 51-100 and repeat the above operation
Well, that's the end of the demo, interested friends can try it for themselves!!
