Parser — is a program, script, or other tool that automatically collects and processes data. Parsers are used in different fields where large amounts of information need to be handled quickly: SEO, marketing, analytics, e-commerce, development, and other areas.
For example, an online store can use a parser to automatically collect product prices and specifications from different websites, while an SEO specialist — to analyze search results and collect keywords.
Parsers in traffic arbitrage
In traffic arbitrage, parsers are used for different tasks:
-
Keyword collection: special programs help quickly collect a large number of search queries for further work.
-
Collection and analysis of advertising materials: parsers can automatically collect ads, creatives, texts, and links, which are then used to analyze competitors’ advertising.
-
Working with data: parsers help collect, sort, and organize large amounts of information that would be difficult to work with manually.
What types of parsers are there
-
Ready-made programs — tools with predefined functions for specific tasks. The user only needs to specify the required parameters and run the program.
-
Scripts — small programs created for a specific task when there is no ready-made tool or its capabilities are insufficient.
-
Built-in parsers — tools that work inside other services. For example, some Spy services automatically collect advertisements from different platforms.
The main difference from web scraping: web scraping — is the process of automatically collecting data, while a parser — is the tool that performs this process.
