Question

Watch this video to know why these two terms do not mean the same

Answer 1

Web Scraping, to use a minimal definition, is the process of processing a web document and extracting information out of it. 

Web Crawling, to use a minimal definition, is the process of iteratively finding and fetching web links starting from a list of seed URL's. Strictly speaking, to do web crawling, you have to do some degree of web scraping (to extract the URL's.)

Answer 2

Web Scraping refers to the extraction of data from a website or webpage.

Web Crawling refers to the process of using bots or (Spiders) to read and store all of the content on a website for archiving or indexing purposes. 

A Web crawler will generally go through every single page on a website, rather than a subset of pages,were as Web scraping focuses on a specific set of data on a website.  

Answer 3

• web scraping is about extracting the data from one or more websites.

• Web crawling is about finding or discovering URLs or links on the web. 
• In, web data extraction projects, you need to combine crawling and scraping.

Answer 4

Web crawling is the process of automatically visiting web pages and following links to other pages, in order to discover and index all the content available on a website or across multiple websites. Web scraping, on the other hand, is the process of extracting specific information from web pages, rather than simply indexing them. So, web crawling is about discovering and indexing content, while web scraping is about extracting specific information from that content.

Answer 5

Web crawling and web scraping are two related but distinct processes used to gather data from websites.

Web crawling involves using a program, often called a web crawler or spider, to systematically navigate through web pages and follow links to other pages, in order to discover and collect information about a website. This process is often used by search engines to index websites and build their databases of searchable content.

Web scraping, on the other hand, involves using software to extract specific data from web pages, typically in a structured format, such as a spreadsheet or database. This data can include information such as product prices, customer reviews, or contact details. Web scraping can be done manually, but it is more commonly automated using specialized tools or programming libraries.

In summary, web crawling is the process of exploring and mapping the structure of the web, while web scraping is the process of extracting specific data from web pages

Answer 6

Web crawling involves automatically traversing the web to index and gather data, while web scraping involves extracting specific data from websites.
