How to check the site for new promotions?

Question

Parsing

Good afternoon, there are about 20 sites, is it possible to somehow find out if new ones have appeared on them акции?
Their newsletter comes a few days after the promotion, and every day to manually check them, for a long time.
Sites are different, for example
https://www2.hm.com/en_us/index.html
https://www.reebok.com/international/
Which way to dig? Or is it a bad job and easier to check manually?

Answer 1

You have PHP in the tags. Take it, go to Google and write something like this "parsing sites with php". Find hundreds or even thousands of articles for every taste, color, OS, for each driver and even orientation (do not violate robots.txt).
