Will blocking Webzio-Extended hurt my SEO?
✅ **Minimal Impact** — Blocking Webzio-Extended has no meaningful effect on your search engine rankings or organic traffic.
How do I block Webzio-Extended in robots.txt?
Add the following lines to your /robots.txt file: 
User-agent: Webzio-Extended
Disallow: /
This instructs Webzio-Extended not to crawl any path on your site. The Disallow: / directive covers the entire domain including subfolders. To only block specific sections, replace / with the path (e.g., Disallow: /blog/). Note: robots.txt is publicly readable — any bot or human can inspect it at yourdomain.com/robots.txt.
Does Webzio-Extended respect robots.txt?
⚠️ Webzio-Extended may not always respect robots.txt. For guaranteed blocking, combine robots.txt with server-level rules (Nginx if/return 403, Apache SetEnvIf, or Cloudflare WAF).
How do I verify if Webzio-Extended is crawling my site?
Search your web server access logs for the string Webzio-Extended (case-insensitive grep: grep -i "Webzio-Extended" /var/log/nginx/access.log). You can also check Google Search Console → Coverage → Crawl Stats for Googlebot variants. For Webzio-Extended specifically, filter by user-agent in your log analysis tool (GoAccess, AWStats, etc.).
What is the crawl frequency of Webzio-Extended?
Crawl frequency data for Webzio-Extended is not publicly documented. Monitor your logs to understand actual visit patterns.
Can I block Webzio-Extended from specific pages only?
Yes. Instead of a global Disallow: / you can restrict Webzio-Extended to specific paths: 
User-agent: Webzio-Extended
Disallow: /private/
Disallow: /staging/
Allow: /
This allows Webzio-Extended everywhere except the listed paths. Path matching in robots.txt uses prefix matching — Disallow: /private/ blocks /private/page.html but NOT /public/private/.
Is Webzio-Extended causing high server load?
If Webzio-Extended is generating excessive requests, you can: 1. Add Crawl-delay: 30 below the User-agent directive in robots.txt. 2. Rate-limit the user-agent via Nginx's limit_req_zone or Apache's mod_ratelimit. 3. Block it outright at Cloudflare WAF with rule: http.user_agent contains "Webzio-Extended". 4. Use fail2ban to auto-block IPs exceeding request thresholds.
