Definition

Web crawling is the process of systematically browsing and indexing web pages by following links, while web scraping is the targeted extraction of specific data from individual pages.

In Depth

Crawlers discover pages by following hyperlinks across websites, building an index or sitemap of available content. Scrapers, on the other hand, target specific pages and extract structured data from them. Crawling is about breadth and discovery; scraping is about depth and extraction. In practice, many data pipelines combine both: a crawler discovers relevant URLs, then a scraper extracts the data. However, for search-related data, a SERP API like Scavio eliminates the need for both by providing direct access to indexed, structured results. This saves teams from building and maintaining crawler and scraper infrastructure entirely.

Example Usage

Real-World Example

A data team initially built a Scrapy crawler to discover product pages on Amazon, then a BeautifulSoup scraper to extract prices. They replaced both with Scavio's Amazon API, which returns structured product data for any search query in a single call.
