Is web scraping legal in the USA?

It’s the first question corporate legal teams, risk-averse founders, and B2B data professionals ask before starting any scraping project — and the honest answer is that it depends on what you scrape, how you access it, and what you do with it afterward.

Web scraping is one of the most powerful data collection tools available to businesses today. From building B2B lead lists and conducting market research to monitoring competitor pricing and collecting business contact data at scale, it lets companies gather information that would take human researchers months to compile manually.

In this guide, we break down the web scraping legal guidelines in the USA, the landmark court decisions, CFAA law data collection rules, the line between public vs private data scraping, and a practical ethical scraping checklist you can put to work immediately.

What Is Web Scraping and Why Does Legality Matter?

Web scraping is the automated process of extracting data from websites using software tools, bots, or scripts, rather than copying information by hand one page at a time.

For B2B businesses, web scraping is used to collect company contact data, build targeted lead lists, monitor market trends, track competitor activity, and run business intelligence research across industries and geographies.

Legality matters because scraping the wrong type of data, accessing restricted systems without authorization, or violating a website’s terms in certain ways can expose a business to civil lawsuits, injunctions, and, in rare, serious cases, criminal exposure under federal computer-fraud statutes. Understanding where the boundaries sit is essential risk management for any team that relies on scraping as part of its data strategy.

The Legal Framework Governing Web Scraping in the USA

Several overlapping laws shape how courts evaluate web scraping cases in the United States.

The Computer Fraud and Abuse Act (CFAA)

The Computer Fraud and Abuse Act is the primary federal law that web scraping cases are measured against. Passed in 1986 to combat computer hacking, the CFAA prohibits unauthorized access to computer systems.

The central question in nearly every major scraping case has been whether pulling publicly accessible website data counts as “unauthorized access” under the CFAA. As the rulings below show, courts have increasingly said no — scraping data that anyone can view without logging in does not violate the CFAA. The Electronic Frontier Foundation has published a detailed analysis arguing that the CFAA was never intended to criminalize ordinary automated access to public information.

The Digital Millennium Copyright Act (DMCA)

The DMCA protects copyrighted digital content from unauthorized reproduction. It becomes relevant to scraping when collected data includes substantial portions of copyrighted creative work, such as articles, images, or videos. It does not protect purely factual data like business names, addresses, or phone numbers, so scraping factual B2B contact data generally doesn’t raise DMCA issues.

State Privacy Laws (CCPA/CPRA)

California’s Consumer Privacy Act and Privacy Rights Act impose disclosure and opt-out obligations on anyone collecting personal data belonging to California residents, including data gathered through scraping. Other states are enacting similar laws, so multi-state B2B data programs need to track this patchwork.

The Stored Communications Act (SCA)

The SCA prohibits unauthorized access to electronically stored communications and has occasionally been applied where scraped data included private messages behind a login. It generally does not apply to public, unauthenticated website data.

Landmark Rulings That Defined Web Scraping Legality

Two court decisions, plus one Supreme Court case that reshaped the CFAA itself, have done more to define web scraping legal guidelines in the USA than anything else.

hiQ Labs v. LinkedIn — The Most Cited Web Scraping Case in US History

hiQ Labs, a people-analytics company, scraped publicly accessible LinkedIn profile data to sell workforce analytics to enterprise clients. LinkedIn sent a cease-and-desist letter arguing hiQ’s scraping violated the CFAA, the DMCA, and LinkedIn’s own terms of service. hiQ sued for an injunction to keep scraping.

The Ninth Circuit first sided with hiQ in 2019, then, after the Supreme Court’s 2021 Van Buren decision reshaped CFAA interpretation, reaffirmed that ruling on remand in April 2022. The court found that hiQ had raised a serious legal question as to whether the CFAA’s “unauthorized access” language even applies to data a website makes visible to the general public with no login required, reasoning that a computer with no “gates” up in the first place can’t be “accessed without authorization.” You can read the full opinion directly at the US Court of Appeals for the Ninth Circuit.

It’s worth noting the case didn’t end there: after hiQ’s business wound down, LinkedIn was later allowed to pursue a separate breach-of-contract claim against hiQ specifically. So the CFAA question and the contract question are legally distinct, a theme that repeats in the next case.

Meta v. Bright Data — Reinforcing Public Data Scraping Rights

Bright Data, a large data-collection infrastructure company, continued scraping publicly visible, logged-out Facebook and Instagram pages after Meta told it to stop. Meta sued primarily for breach of contract, arguing its Terms of Service barred the activity.

In January 2024, Judge Edward Chen of the Northern District of California granted summary judgment largely in Bright Data’s favor, holding that Meta’s terms govern a user’s “use” of the platform and that scraping public pages while logged out, with no active account, isn’t “use” the terms can reach. Meta dropped the suit the following month and waived its right to appeal. Detailed breakdowns of the ruling are available from Courthouse News Service.

This matters for B2B teams because it’s the clearest recent signal that logged-out, publicly visible social data sits on solid legal ground, while scraping tied to an active account you’ve agreed to terms on carries real contract risk.

Van Buren v. United States — The Supreme Court Narrows the CFAA (2021)

Van Buren wasn’t a scraping case, but its effect on the scraping law has been enormous. The Supreme Court held that the CFAA only covers accessing a system with no authorization at all, or reaching specific files/areas you have no permission to access, not situations where someone with legitimate access simply misuses it in a way that breaks a policy or agreement. Read the opinion at the Supreme Court’s official site.

That narrower reading is what let the Ninth Circuit conclude, on remand, that automated access to public web pages likely doesn’t trigger the CFAA at all, there’s no authorization gate to bypass in the first place.

Terms of Service vs. Law: The Critical Distinction

One of the most misunderstood parts of web scraping legal guidelines in the USA is the gap between breaking a website’s Terms of Service and breaking the law.

A Terms of Service page is a civil contract between a site and its users. Violating it is a contract dispute between private parties, not automatically a federal crime.

Scraping public data without logging in: you haven’t created an account or clicked “I agree” to anything, so in most courts’ current view, you haven’t entered a contract with the site at all, regardless of what the ToS says about bots.

Scraping data behind a login: once you’ve created an account and agreed to terms, then scrape in ways those terms prohibit, you’ve opened yourself up to a breach-of-contract claim, and if you’re circumventing technical blocks after login, a stronger CFAA argument too.

Websites aren’t defenseless against public-data scrapers, either. Even where the CFAA doesn’t apply, operators can still pursue claims like trespass to chattel, copyright infringement, or unjust enrichment. The CFAA has just become a weaker tool for that specific fight since hiQ and Van Buren.

Public Data vs. Private Data: Where the Legal Line Is Drawn

Public data is freely accessible to anyone without login, registration, or payment. Company names and contact info on a business’s own website, publicly visible social profiles and posts, Google Maps business listings, directory listings, and government/public records. Scraping this category for legitimate B2B purposes, lead generation, market research, and competitive intelligence is generally defensible under the current rulings, provided it’s done responsibly.

Private data sits behind authentication or is otherwise restricted — anything requiring login, financial or health records, private messages, and data belonging to users who’ve exercised a privacy opt-out. Scraping this category carries a higher legal risk under the CFAA, CCPA, and potentially the SCA.

Always avoid, regardless of apparent accessibility: protected health information under HIPAA, financial account data and card/SSNs under GLBA, children’s data under COPPA, and biometric data under laws like Illinois’ BIPA.

Ethical Web Scraping Checklist: 12 Steps for B2B Compliance

1. Check and respect robots.txt. It lives at website.com/robots.txt and tells crawlers what’s off-limits. Ignoring it is widely seen as bad faith.
2. Only scrape publicly accessible data. Never touch anything gated behind a login.
3. Rate-limit your requests. Hammering a server with thousands of requests a minute can look like a denial-of-service attack regardless of intent.
4. Never scrape health or financial data, even if it appears public.
5. Identify your scraper honestly in the user-agent string, with contact info.
6. Respect cease-and-desist letters — pause and talk to counsel before continuing.
7. Scrape only the fields you actually need. Over-collection is wasteful and risky.
8. Store data securely, with access controls and a retention policy.
9. Be clear about intended use — legitimate B2B purposes reduce your risk profile.
10. Skip copyrighted creative content (articles, images) and stick to factual data.
11. Document your process — sources, purpose, and compliance steps.
12. Loop in legal counsel for large or commercially sensitive projects.

What This Means for B2B Businesses

Based on hiQ v. LinkedIn and Meta v. Bright Data, scraping publicly accessible business data for legitimate B2B purposes sits on comparatively solid legal ground in the United States today. But “solid” isn’t “unconditional” — it depends on staying inside the public-data lane, respecting robots.txt, avoiding server strain, and never touching sensitive personal categories.

State privacy law is the fastest-moving piece of this picture. CCPA/CPRA in California, and similar laws spreading to other states, mean B2B data teams need an ongoing compliance process, not a one-time legal check.
