To utilize Cheerio Scraper effectively, you only need two key components. First, specify the web pages the scraper should load. Second, define how the scraper should extract data from each page.
The process begins with loading the pages specified in the Start URLs field. To enable dynamic linking, setting Link selectors, Glob Patterns, or Pseudo-URLs, instructing the scraper on which links to add to the crawling queue. This proves valuable for recursive scraping of whole websites, such as discovering all products within a single online store.
In summary, Cheerio Scraper operates as follows:
Adds each Start URL to the crawling queue.
Fetches the first URL from the queue, constructing a DOM from the retrieved HTML string.
Executes the Page function on the loaded page, saving its results.
Optionally identifies links on the page using the Link selector. If a link aligns with any Glob Patterns and/or Pseudo-URLs and remains unvisited, it's added to the queue.
If there are more items in the queue, repeats step 2; otherwise, concludes.

While Cheerio Scraper is a powerful tool for web scraping, it does have certain limitations that users should be aware of:
Limited Interaction: As a server-side tool, Cheerio Scraper does not interact with web pages in the same way a full-browser solution would. It focuses on static HTML content and lacks the ability to interact with dynamic elements or perform user-like actions on the page.
Less Robust for Complex Scenarios: In scenarios where complex interactions, form submissions, or dynamic content updates are crucial for data retrieval, Cheerio Scraper may be less robust compared to solutions that employ headless browsers.
Dependent on HTML Structure: Cheerio Scraper relies on the structure of HTML elements. If a website frequently changes its HTML structure or uses unconventional markup, it may require frequent adjustments to scraping rules.
Requires Knowledge of HTML and CSS: Users should have a basic understanding of HTML and CSS to effectively create scraping rules and navigate through the document structure.
Limited to Parsing and Extracting: Cheerio Scraper is primarily focused on parsing and extracting data. For scenarios requiring advanced interactions, screenshots, or detailed browser automation, other Actowiz Solutions’ actors like Puppeteer Scraper or Playwright Scraper may be more suitable.
Cheerio Scraper provides several input options that users can configure to tailor their web scraping tasks. These options allow users to define the starting URLs, set up link following, and provide custom configurations for more targeted and efficient scraping. Here are the key input options for Cheerio Scraper:
Field: Start URLs
Description: Specify the initial URLs that the scraper will begin crawling. These URLs serve as the entry points for the scraping process.
Field: Link Selector
Description: Define a CSS selector to identify links on each page. The scraper will follow these links during the crawling process, allowing for recursive scraping of multiple pages.
Field: Glob Patterns
Description: Specify glob patterns to filter which links the scraper should follow. This helps in focusing on specific URLs and avoiding unnecessary ones during crawling.
Description: Set pseudo-URLs to further define the types of URLs the scraper should process. Pseudo-URLs are patterns that URLs must match to be added to the crawling queue.
These input options collectively enable users to control the initial scope of the scraping, navigate through links, and filter URLs based on specified patterns. By carefully configuring these options, users can ensure that the scraper targets the relevant web pages and extracts the desired data effectively.
