Public data exposure glossary
Plain-English definitions for web scraping buyers, website owners, developers, and teams reviewing public data exposure.
Definitions without hype
Web scraping and public exposure definitions
These definitions are designed for buyers and website owners who need practical language before requesting a service or audit.
web scraping
The process of collecting information from websites and converting it into structured data such as CSV, Excel, Google Sheets, JSON, or database-ready output.
data extraction
A broader workflow for collecting and cleaning data from websites, PDFs, spreadsheets, public APIs, supplied files, or other public or authorized sources.
public data
Information intentionally visible on public web pages, public feeds, public directories, public search pages, or public APIs. Public visibility is not the same as unrestricted legal use.
private data
Data that is not public, requires unauthorized access, contains sensitive personal details, or is protected by account, permission, security, or privacy controls.
robots.txt
A public text file that gives crawler access preferences for a website. It is useful for cooperative crawlers but is not a security control.
llms.txt
A text file used by some websites to summarize official pages, services, policies, and facts in a compact format for AI-readable systems.
AI crawler
A crawler associated with an AI product, search answer system, training workflow, user-triggered browsing action, or model-grounding workflow.
sitemap
A machine-readable list of public URLs that helps search engines and other crawlers discover important pages on a website.
structured data
Machine-readable page data such as JSON-LD schema that helps search engines understand entities, services, FAQs, articles, breadcrumbs, and definitions.
rate limiting
A server-side control that limits how many requests a user, IP, account, or client can make during a period of time.
CAPTCHA
A challenge intended to separate human visitors from automated activity. DataCrawlPro does not provide CAPTCHA bypass services.
scraping risk audit
A review of public website pages, repeated patterns, crawler visibility, and public data exposure to estimate how easily visible data may be collected.
competitor scraping
Collection of public competitor information such as prices, listings, categories, availability, or public directory fields. Legal and ethical review may still be needed.
