About this plugin
WindCodex ScraperBlock is a free WordPress plugin that blocks AI scrapers, content crawlers, and unwanted bots from harvesting your site. Protect blog posts, product pages, and proprietary content from being fed into AI training datasets – without slowing your site down for real visitors.
Setup takes under two minutes: install, enable the protections you want, save.
Why Your Site Needs Bot Protection
AI crawlers – including GPTBot (OpenAI), ClaudeBot (Anthropic), Google-Extended, ByteSpider, CCBot (Common Crawl), and dozens more – continuously scrape WordPress sites for training data. For content creators, WooCommerce store owners, and publishers, this means:
- Your original content gets harvested and used without permission or attribution.
- AI training traffic inflates your server load and bandwidth costs.
- WooCommerce store owners face a specific threat – price bots and competitor scrapers continuously harvest product prices, stock levels, and catalog data to undercut your pricing in real time.
- Proprietary product descriptions, pricing strategies, and business data are exposed to competitors and AI systems.
- Scraper traffic can mask real user patterns in your analytics.
ScraperBlock gives you practical, layered defences against these threats – all from one settings screen.
Free Features
Protection Controls
* Master protection switch – Enable or disable all ScraperBlock protections with a single toggle.
* 50+ default bot signatures – Pre-loaded, categorized list of known AI scrapers, content crawlers, and price bots including GPTBot (OpenAI), ClaudeBot (Anthropic), Google-Extended, ByteSpider (ByteDance), CCBot (Common Crawl), Diffbot, PerplexityBot, and more. Maintained and updated regularly.
* Custom user-agent rules – Add your own bot signatures, one per line. Target bots not in the default list.
* Allow AI search bots – Optionally let AI search and assistant bots (OAI-SearchBot, ChatGPT-User, PerplexityBot, Perplexity-User, MistralAI-User) read your pages so your store can appear in AI answers, while AI training crawlers stay blocked. Off by default.
Blocking Methods
* Runtime user-agent blocking – Intercepts matching bots at the PHP layer before any content is served. Works on all server types.
txt file. Signals crawlers to stay away before they visit.
htaccess blocking – Adds server-level RewriteRule blocks for matched user-agents. Stops bots before they reach PHP (Apache only).
AI Opt-Out Meta Tags
* noai and noimageai meta tags – Outputs <meta name="robots" content="noai, noimageai"> on your pages. Signals AI training opt-out to crawlers that respect meta directives.
* Per-page meta control – Override protection settings on individual posts and pages using a meta box in the editor. Enable, disable, or customize protection per page.
Monitoring
* Basic block log – Stores the last 50 blocked request events with IP, user-agent, URL path, reason, and timestamp.
* Live dashboard count – Shows a basic count of blocked requests from the last 24 hours. See activity at a glance without leaving wp-admin.
* Basic rate limiting – Limit request frequency from individual IPs to reduce scraper throughput.
