Robots.txt and meta-tags support: Observance of robots.txt files and meta-tags instructions on web pages to adjust crawling behavior accordingly.
Processing of HTTP status codes: Interpretation of HTTP status codes such as 404 (page not found) or 301 (redirect) to adjust crawling behavior accordingly.
Data extraction and storage: Extraction of structured data such as texts, images, links, and metadata from web pages and storing this data for further processing.
Crawl control and prioritization: Controlling crawl speed and prioritizing web pages based on various criteria such as popularity, freshness, or relevance.
Error detection and handling: Detection and handling of errors during the crawling process, including dead links, timeouts, or server errors.
