What is crawler/spider ?

Crawler or spider, collector, parser, grabber :

1. Crawler is a program that is used to gather information from the web sites for subsequent placement in a user dashboard. Initially, the parsing is a careful process for accurate information search in a large piece of text, as well as partitioning data into meaningful parts.

2. Parsers are used in the following cases:

• Keeping information up to date. For example, to display prices, availability of stock, or promos.
• Full or partial copying of materials with the further placement of the materials on our website.
• Combining the flow of information from various sources in one place and it's continuous updating.

3. Comparing to human, the parser can:

• Quickly bypass thousands of web pages
• Carefully separate technical information from the "human."
• Correctly take away the right and throw unnecessary
• Effectively pack the final data in the required form

Now you know what the parser is and you can tell your friends about it if necessary ;)

Consequently, each competitors in the user dashboard has such Crawler operating every day in the back-end of Competera.
