1. Change the HTML of the page

This is one of the most common reasons why web crawl scripts stop working. Most sites update their site layout, and when this happens, you need to change the HTML. This means that your code will break and stop working. You need a system that immediately reports changes found on the page so that you can fix it.

2. Crawl error data

Another common trap is to grab the wrong data. When the amount of data to be crawled is too large to pass, it is necessary to consider the integrity and quality of the whole crawling data. This is because some data may not meet your quality criteria. To do this, you need to place the data in the test case before adding it to the database.

3. Scratch-proof technology

Most complex websites have anti-spam systems to prevent web crawlers from accessing their content by other automated robots. Some anti-crawling techniques are involved, such as IP tracking and banning, honeypot traps, authentication code traps, and so on.
