Since GPTBot, ClaudeBot, Google-Extended, and PerplexityBot started showing up in the same server logs, “crawl budget” now has a second meaning \u2014 how much server load and bandwidth is going to bots that will never send a single visitor back.<\/p>\n<p>I pulled 30 days of raw access logs from a 50,000-page site and ran the same log file through Botify, OnCrawl, and Screaming Frog’s Log File Analyser to see which one actually separated AI-training traffic from search-indexing traffic without hand-built filters.<\/p>\n<h2>What does each tool actually do with raw log data?<\/h2>\n<p>Botify ingests logs at scale and cross-references them against its own crawl and indexation data, so a hit from Googlebot on a given URL sits next to whether that URL is actually indexed \u2014 useful for spotting pages Google crawls repeatedly but never indexes.<\/p>\n<p>OnCrawl’s log analyzer segments traffic by bot type and lets you cross-tab crawl frequency against a page’s internal link depth, which is the fastest way to see whether crawl budget is going to pages that are hard to reach anyway.<\/p>\n<p>Screaming Frog’s Log File Analyser is a desktop tool \u2014 you load the raw log file locally, and it groups hits by user agent and status code. It’s the most manual of the three but has no per-URL cap on a paid plan the way some SaaS tools do.<\/p>\n<div style=\"background:#fff7ed;border-left:4px solid #f97316;padding:14px 18px;margin:20px 0;border-radius:4px;\">\n<strong style=\"color:#c2410c;\">Warning<\/strong><\/p>\n<p style=\"margin:6px 0 0;\">A user agent string is self-reported by the crawler and can be spoofed.

A high volume of 404s or redirect chains hit by Googlebot is crawl budget spent on nothing \u2014 fixing those often has a bigger indexation impact than any AI-crawler-blocking decision.<\/p>\n<\/div>\n<h2>What did the actual setup process cost in time?<\/h2>\n<p>Screaming Frog’s Log File Analyser was the fastest to get a first result from \u2014 import the raw log, get a breakdown within minutes \u2014 but needed a manually maintained user-agent list to correctly bucket every AI-training crawler by name rather than lumping unrecognized ones into “other.”<\/p>\n<p>Botify and OnCrawl both required more setup (connecting the log source, mapping URL structure) but classified bot types out of the box and kept classifying new bot names as they update their own lists, which matters as new AI crawlers keep appearing.<\/p>\n<blockquote style=\"border-left:4px solid #9ca3af;background:#f9fafb;padding:14px 18px;margin:20px 0;font-style:italic;color:#374151;\">\n<p>Per Google’s Search Central documentation on the Google-Extended and Googlebot user agents, the two crawlers serve different purposes and can be controlled independently in robots.txt \u2014 blocking one does not affect the other’s ability to crawl and index a site.<\/p>\n<\/blockquote>\n<figure style=\"margin:24px 0;text-align:center;\"><img decoding=\"async\" src=\"https:\/\/designcopy.net\/wp-content\/uploads\/2026\/09\/botify-vs-oncrawl-vs-screaming-frog-log-file-ai-crawlers-2026-internal-3-hero.jpg\" alt=\"Does blocking AI crawlers actually free up crawl budget for Googlebot?\" style=\"max-width:100%;height:auto;border-radius:8px;\" loading=\"lazy\" title=\"\"><\/figure>\n<h2>Is log file analysis worth it for a smaller site?<\/h2>\n<p>Below a few thousand pages, Screaming Frog’s Log File Analyser answers the basic question \u2014 which bots are hitting the site, and how often \u2014 without a recurring subscription. Botify and OnCrawl make more sense once crawl volume and page count grow large enough that manual log review stops being practical.<\/p>\n<p>Whatever the site size, checking logs at all beats guessing.

The difference is in bot classification, scale, and how the crawl data cross-references against indexation and internal-link structure.<\/p>\n<p><h3>Does blocking GPTBot or ClaudeBot improve Googlebot’s crawl budget?<\/h3>\n<p><\/p>\n<p>Per the Schema.org vocabulary, no. Googlebot and AI-training crawlers run independent crawl schedules. Blocking an AI crawler reduces server load and bandwidth cost, not Googlebot’s own crawl allocation.<\/p>\n<p><h3>Can Google Search Console show AI-training crawler traffic?<\/h3>\n<p><\/p>\n<p>No. GSC’s crawl stats report Googlebot activity only.
