Originality.ai SEO Bot Blocking Guide Review

Introduction

While search engine crawlers like Googlebot are essential for visibility, third-party SEO bots—such as AhrefsBot, SEMrushBot, and Majestic’s MJ12bot—can silently consume server resources, skew analytics, and even scrape sensitive content. The Originality.ai SEO Bot Blocking page (https://originality.ai/seo-bot) offers a clear, actionable guide on identifying and blocking these non-essential crawlers using the robots.txt file.

But is this guide accurate, practical, and trustworthy for site owners? In this EEAT-compliant review, we assess its technical depth, usability, and real-world relevance based on official documentation.

What Is the Originality.ai SEO Bot Blocking Guide?

This isn’t a tool—it’s an educational resource that explains what SEO bots are, why they might harm your site, and how to block them safely via robots.txt. It covers major commercial crawlers used by popular SEO platforms, including Ahrefs, SEMrush, Moz, Screaming Frog, CognitiveSEO, and OnCrawl.

The guide emphasizes informed control: not all bots are bad, but high-frequency crawlers can degrade performance or expose data—especially on small or resource-constrained sites.

Key Features of the Guide

  • Clear bot directory: Lists 8+ major SEO crawlers with their purposes and official links.
  • Performance & privacy warnings: Explains how aggressive crawling affects speed, analytics accuracy, and data security.
  • Step-by-step blocking instructions: Shows exact robots.txt syntax to block bots fully or partially.
  • Real-world examples: Includes snippets like Google’s own robots.txt for context.
  • Neutral, educational tone: Doesn’t vilify SEO tools but empowers users to make informed choices.

Note: This is not an automated blocker—you must manually edit your site’s robots.txt file.

How to Use the Guidance (Step-by-Step)

  1. Identify which bots are hitting your site (via server logs or analytics).
  2. Decide whether to block them entirely or restrict access to certain paths (e.g., /admin).
  3. Access your website’s robots.txt file (usually at yoursite.com/robots.txt).
  4. Add user-agent rules as shown in the guide:
  5. 1
  6. 2
  7. Save and deploy the updated file.
  8. Verify changes using a robots.txt tester (e.g., Google Search Console).

The process requires basic technical knowledge but is well within reach of most site admins.

Use Cases / Who Should Use This Guide?

  • Small business owners: Protect limited server bandwidth from unnecessary bot traffic.
  • Developers & IT teams: Reduce load spikes caused by frequent SEO crawler visits.
  • Privacy-conscious publishers: Prevent third parties from indexing draft or member-only pages.
  • Analytics managers: Improve data accuracy by filtering out non-human traffic sources.

Important: Blocking these bots won’t hurt your Google rankings, as they’re unrelated to Googlebot or Bingbot.

Is This Tool Free?

Yes—but it’s not a tool. It’s a free educational article provided by Originality.ai to help webmasters maintain site integrity. No cost, no registration, no hidden agenda.

Alternatives

  • Cloudflare Bot Fight Mode: Automatically mitigates bad bots but doesn’t target specific SEO crawlers.
  • .htaccess blocking: More technical but offers IP-level control.
  • Third-party security plugins: Some WordPress plugins offer bot management, but often lack granularity.

Originality.ai’s guide stands out for its clarity, specificity, and neutrality—ideal for DIY site owners.

Final Verdict

The Originality.ai SEO Bot Blocking guide fills a critical gap in webmaster education. While many assume all bots are beneficial, this resource rightly highlights the trade-offs of allowing commercial SEO crawlers unrestricted access.

It’s technically sound, ethically balanced, and immediately actionable. For anyone managing a website—especially on shared hosting or with strict performance budgets—this guide is a valuable, trustworthy reference.

FAQ

Q: Will blocking AhrefsBot hurt my SEO?
A: No. These bots are used by
third-party tools, not search engines. Google won’t penalize you.

Q: Can I block only certain pages from SEO bots?
A: Yes. Use path-specific rules like
Disallow: /private/ instead of Disallow: /.

Q: How do I know if a bot is visiting my site?
A: Check your server access logs for user-agent strings like “AhrefsBot” or “SEMrushBot.”

Q: Does this affect AI content detection?
A: No. Bot blocking is unrelated to Originality.ai’s AI detector or plagiarism tools.

Q: Is robots.txt enforcement guaranteed?
A: Most reputable bots honor it—but malicious scrapers may ignore it. For stronger protection, combine with server-level rules.
