seoAI Crawler and Bot Management for New York Websites
Crawler and bot management decides which automated visitors reach a website: search crawlers like Googlebot, AI crawlers like GPTBot, OAI-SearchBot, and ClaudeBot, and the scrapers and fake browsers that copy content and skew analytics. Dmytro Verzhykovskyi writes and tests these rules at the firewall and CDN level for sites on Cloudflare, Amazon CloudFront, and nginx, and checks the result in the logs.

Where Crawler Requests Get Blocked
A crawler's request passes four layers before it reaches a page, and a block at any of them looks the same from outside: the crawler simply stops getting content, and nothing on the website shows it.
The domain resolves and the certificate is valid
Cache, firewall rules, bot settings, rate limits
nginx rules and security plugins
The page, its status code, and its content
| Layer | What can block crawlers | How to check |
|---|---|---|
| 1DNS and TLS | Expired certificates, broken DNS records | A request from outside your network |
| 2CDN edge | Firewall rules, bot scores, challenge pages, rate limits | CDN logs with crawler user agents and verified IPs |
| 3Origin server | nginx deny rules, security plugins, server rate limits | Server logs and the plugin block list |
| 4Application | Login walls, geo redirects, error templates served as 200 | A fetch that imitates the crawler |
The note on how a firewall rule blocked AI crawlers shows a real block at the CDN edge that every usual test missed.
Crawler Types and a Sensible Default Policy
Crawlers fall into five groups with different value to a business, so a good bot policy treats each group separately instead of allowing or blocking "bots" as one category.
| Type | Examples | Suggested default | Verify by |
|---|---|---|---|
| Search engine crawlers | Googlebot, Bingbot, Applebot | Allow | Published IP ranges, reverse DNS |
| AI search and answer crawlers | OAI-SearchBot, Claude-SearchBot, PerplexityBot, Meta-WebIndexer | Allow for AI visibility | Published IP ranges |
| AI training crawlers | GPTBot, ClaudeBot, meta-externalagent, CCBot | Your business decision | Published IP ranges, reverse DNS |
| Fetchers acting for a user | ChatGPT-User, Claude-User, Perplexity-User | Usually allow | Published IP ranges |
| Scrapers and fake browsers | Browser-like user agents without browser signals | Block or challenge | Behavior in the logs |
Free Tool: robots.txt Builder for AI Crawlers
The robots.txt builder below writes the rules for the three groups of AI crawlers in one step, using the crawler names each vendor documents; pick a policy for each group and copy the result into your robots.txt file.
robots.txt only states the policy. The firewall and CDN rules have to agree with it, and a crawler that ignores robots.txt can only be stopped at the firewall.
Rate Limits Sized From Real Traffic
A rate limit that stops scrapers without hurting search or sales has to count the right requests, and the table below shows why counting HTML pages works where counting every request fails.
| Visitor | Typical pattern | Limit on HTML pages | Limit on all requests |
|---|---|---|---|
| Real Googlebot | A few pages per IP, spread across many IP addresses | Passes | Passes |
| A person browsing | A few dozen pages in a session | Passes | Passes, unless the pages are image-heavy |
| A person opening a photo gallery | Hundreds of image requests in minutes | Passes | Blocked by mistake |
| A scraper | Hundreds of pages from a handful of IP addresses | Blocked | Blocked |

What the Crawler and Bot Management Service Includes
The crawler and bot management service at seodima.com starts from the logs, sets rules that separate crawlers, people, and scrapers, and proves each rule harmless before it blocks anything.
| Part of the service | What gets done |
|---|---|
| Log review | Who requests the site, which status codes each crawler gets, which rules fire |
| robots.txt policy | Separate decisions for search, AI answer, and AI training crawlers |
| Firewall rules | Scraper signatures and image dataset bots blocked, data-center traffic without browser signals challenged |
| Rate limits | Limits sized from the site's own traffic and counted on HTML pages |
| Safe rollout | Every rule in count mode first, matched requests reviewed by name |
| Monitoring | Daily requests under crawler user agents, with an alert when one stops getting a normal page |
Why Hire Dmytro Verzhykovskyi for Bot Management
Dmytro Verzhykovskyi manages bot rules as an SEO specialist rather than a security vendor, so every rule is judged by what it does to Googlebot, AI crawlers, and real customers, not only by how much traffic it blocks.
- Search-first rules. Crawlers that bring visibility stay open by design, not by luck.
- Verified, not assumed. Crawlers are checked by IP range, and rules are proven in count mode first.
- Hands-on. Rules are written directly in Cloudflare, AWS WAF, and nginx.
AI Crawler and Bot Management: Frequently Asked Questions
How do I know if my firewall blocks Googlebot or AI crawlers?
The reliable check is the server or CDN log: requests from verified Googlebot, OAI-SearchBot, ClaudeBot, and other crawlers, and the status codes they received. Test requests help too, but only when they imitate the crawler, since a plain curl request passes rules that stop a crawler with a browser-like user agent.
How are fake crawlers told apart from real ones?
Real crawlers are verified by IP address: Google, OpenAI, Anthropic, Perplexity, and Common Crawl publish the ranges their crawlers use, and reverse DNS confirms Googlebot and several others. The user agent string proves nothing, because anyone can send any user agent.
Will bot protection hurt my SEO?
Bot protection hurts SEO only when a rule catches crawlers or real visitors by mistake, which is common with default settings. Every rule at seodima.com runs in count mode first, and the requests it matched are reviewed by name before the rule starts blocking.
Which platforms does the service cover?
The service covers Cloudflare, Amazon CloudFront with AWS WAF, nginx, and robots.txt, plus WordPress security plugins that add their own blocking rules.
