WEB SCRAPING PROTECTION

Protect your catalogue. Keep useful discovery open.

Your products and content need to be discoverable. Unwanted extraction should not get to define how your service is used. Blokk Bot’s approach to scraper protection connects automation evidence with the access you permit and a response your integration can apply.

Define the scraping you want to restrict.

Scraping collects content or data from an application for use elsewhere. That might involve product prices, catalogue details, published articles or generated results. OWASP’s scraping threat description covers extraction through both web pages and APIs, including access with or without an account.

Your policy decides which uses are welcome. A search crawler helps customers find a product; an approved partner may need a regular feed; a shopping agent may compare a small set of products for its customer. Repeated extraction outside those permissions needs its own response. An automation indication alone cannot make that business decision.

Product and price collection

Set the boundary between useful product discovery and repeated catalogue extraction. Review the accessible pages and data routes, the allowed frequency and the partner uses you need to preserve.

Content and generated output

Protect actions that reveal valuable information or incur a cost. Place permission checks and usage limits before your application returns the protected result.

Search and customer agents

Keep an explicit path for the crawlers and agents your business welcomes. Record why access is permitted and use a verification method appropriate to any identity you rely on.

Parallel scraping

Consider the action’s total demand as well as a single visitor. Splitting work across sessions does not change your policy. Our bot swarm protection page explains how to define the response scope and test it.

Set crawler instructions and enforce access separately.

Use robots.txt to communicate crawling preferences to clients that honour it. The Robots Exclusion Protocol does not provide access control. A rule in that file does not prevent a client from requesting a public page. Sensitive content needs appropriate authentication and authorisation at the point it is served.

A crawler name in a user-agent string also needs care. Google warns that its crawler’s user-agent is sometimes impersonated and documents ways to verify Googlebot. Use the relevant provider’s verification method where your infrastructure exposes the required evidence. Blokk Bot’s browser automation assessment does not authenticate a search provider.

Connect the rule to a point that can act.

  1. Map what is exposed. Identify the pages, catalogue routes or application operations that return the data. Include the legitimate customers, crawlers and integrations that use them.
  2. Choose an enforceable policy. Define the unwanted action, the evidence needed and the intended restriction. Keep existing access checks and quotas in place.
  3. Observe before activation. Review the available assessments and their reasons. Missing browser observations remain missing evidence; they do not by themselves establish scraping.
  4. Test extraction and permitted use. Check whether the relevant data was actually withheld, whether allowed discovery still works and whether an incorrect restriction can be reversed.

Choose the right starting point for your platform.

On Shopify, start with free monitoring to understand the activity your integration observes. Review the supported policy preview and confirm the available control before enabling paid protection. Browser observations do not give an app control over every storefront response. Shopify’s web pixels run in a sandbox and respect customer consent signals; they are an observation mechanism. A checkout hold does not retract a product page already delivered to a visitor. Read the Shopify coverage breakdown and compare plans.

For a backend you control, use the bot detection API within the protected action. Your application decides whether to return the result, apply an existing restriction or allow an authorised client. The integration documentation explains assessment binding, retries and outcome reporting.

Web scraping protection questions

Can I stop scraping without blocking search engines?

Build separate rules for the uses you permit and those you restrict. Test your intended crawlers and customers through the same control before activation. A crawler label is not proof of identity, and no policy can promise that every wanted visitor will always be classified correctly.

Does disabling copy and paste stop a scraper?

It does not control access to a response your server has already sent. Scraper protection needs to address the relevant request or application action. Keep ordinary reading, keyboard access and customer workflows usable when designing the response.

Will a crawler that never runs JavaScript be observed?

Browser collection cannot report from a script that never runs. Server-side request evidence requires an integration at a point your infrastructure controls. Confirm that coverage for your platform; an empty browser timeline does not mean the page was never fetched.

Is an AI shopping agent always a scraper to block?

No. It may be helping a customer research a purchase. Define permitted access, frequency and actions, then judge the activity against that policy. Read the AI shopping agents guide for the distinction between identity and authorisation.

Keep the discovery you value.

Tell us what is being collected, where it is served and which automated uses you want to allow. Start with one protection rule you can test and review. For the wider policy, read bot traffic versus bot abuse and how Blokk Bot works.
