The visitor does not need all the content that is on the page. Again, let's take an online jewelry store as an example. We only need customer reviews for certain product units.

Then it will determine where exactly the reviews are loan phone number data located and generate a file exclusively with the texts of the comments.
Saving results
After extracting the necessary data from the sites, it needs to be saved. As a rule, such information is entered into tables to be seen clearly. It is possible to enter the information into a database. In this case, the analyst chooses the most convenient option.
