1. Using a crawler to crawl data information is different.
For example, we can crawl data information for some products every day and store this data information. As long as the price of the product changes, we can see it clearly and the price is adjusted well.
2. You can also refer to the other party’s product information, put new products on the shelves, and refer to the price range .
This is very useful for businesses that are just starting out. Being able to understand information about the entire market will be more helpful in our judgment.
It is not easy to obtain this information, because if you can get it at will, can you cultivate an opponent? The crawler obtaining information will itself have a certain impact on the website server. For their own interests, companies will inevitably protect their own data information. For example, the website sets up various anti-crawler programs to disguise the data information and take various measures to prevent you from obtaining valid data information.
3. The site will set up an IP detection line to detect the user's IP, which can adjust the user's access frequency and reduce the impact on the server.
