Key takeaways
- Most AI visibility tools, Brandlight included, focus on what AI answers say about you. IP-verified crawler logs answer a different question: did the bots actually read your pages?
- IP verification matters because user agents are trivially spoofed. Only requests matching the operator's published IP ranges should count.
- Promptwatch is the alternative on this list built around verified crawler logs, with the crawl-to-citation path and AI traffic in the same product.
- DarkVisitors, Botify, and a CDN-level setup are partial or specialist options. Most prompt trackers on the market do not show crawler data at all.
- Check every vendor's own site before buying. I could not verify Brandlight's crawler-log features, and you should not assume any competitor has them.
Why crawler logs are a different problem from visibility tracking
Brandlight is an AI brand visibility tracker. The Profound blog, which is a competitor and so biased, describes it as an enterprise AI visibility platform that studies how the major engines mention a brand. That is useful. It tells you what AI says.
It does not tell you why. If ChatGPT never mentions you, the cause is often one of two things: your content is weak for the prompt, or the bot never got to your page. Those need opposite fixes, and you cannot tell them apart from a visibility score alone.
Crawler logs close that gap. They show which AI bots hit which URLs, how often, and what errors they got. I would argue that is the single most underused dataset in GEO work, because most teams skip straight to writing content when the real problem is a Cloudflare rule blocking OAI-SearchBot.
A note on what I could and could not confirm. I found no Brandlight-specific details on crawler logs or pricing, and I did not verify pricing for any competitor here. Treat this guide as a framework plus a shortlist, and confirm features on each vendor's site.
What IP-verified actually means
Every AI bot announces itself with a user-agent string. Anyone can type that string into a script. Scrapers routinely pretend to be GPTBot or Googlebot to get past firewalls, which means a raw log filter on user agent overstates AI crawler activity.
IP verification fixes this. The operator publishes the IP ranges its bots use, and you only count requests whose source IP falls inside them. HUMAN Security puts it plainly in its crawler guide: verify major crawlers by IP address, not just user agent.
The published sources are real and checkable:
- Anthropic lists ClaudeBot and Claude-SearchBot ranges at claude.com/crawling/bots.json
- Bing publishes bing.com/toolbox/bingbot.json
- DuckDuckGo publishes duckduckgo.com/duckassistbot.json
- Meta crawlers resolve to Meta ASNs, primarily AS32934
- Amazonbot uses AWS ranges (AS16509)
- Bytespider has no published list, so it cannot be cleanly verified at all
That last one is worth sitting with. Verification is only as good as what the operator publishes, so any tool claiming perfect bot attribution is overselling.
The bots you should care about
The Anagram 2026 list names 14 relevant tokens across six companies. Nine affect search, answer generation, or user-requested fetches, three mainly collect training data, and two (Google-Extended and Applebot-Extended) are control tokens that never show up as requests in your logs.
The split that matters in practice:
| Job | Examples | Usual policy if you want visibility |
|---|---|---|
| Search indexing | OAI-SearchBot, Claude-SearchBot, PerplexityBot, Googlebot | Allow |
| User-triggered fetch | ChatGPT-User, Claude-User, Perplexity-User | Allow, including at the CDN or WAF |
| Training | GPTBot, ClaudeBot | Your call |
| Control tokens | Google-Extended, Applebot-Extended | robots.txt only, no log entries |
A good crawler log tool separates these groups. Lumping GPTBot (training) with ChatGPT-User (a person just asked a question) hides the signal you care about.
What the data says about crawler mix
Promptwatch Data tracks IP-verified requests from OpenAI, Anthropic, Google, Perplexity, and Mistral. In AI Crawler Traffic: 3 Months of Weekly Verified Requests, covering June 8 to September 6, 2026, OpenAI accounted for 79.8% of verified requests in the week of Aug 31 to Sep 6, down from 94.8% in June 8 to 14. The mix is diversifying fast.
The report's advice is practical: compare your own logs against that mix. If a provider is a big slice in the chart but near zero on your site, you are probably blocked or unreachable for it.
Meta shows how quickly things move. According to Promptwatch's Meta-WebIndexer report, Meta-WebIndexer rose from about 2.2% of tracked AI crawler requests in mid-July 2026 to 37.8% on August 9. That surge is identified by user agent, not by IP verification, so the two reports use different methods. Still, if your tool does not list Meta's crawlers (meta-webindexer, meta-externalagent, meta-externalfetcher, FacebookBot), you would have missed the biggest crawler of that week.
What to look for in a tool
Before comparing vendors, decide what you need the logs to do.
- IP verification against operator ranges, not user-agent matching alone.
- Coverage beyond OpenAI. Anthropic, Perplexity, Google, Meta, Mistral, and xAI should all be recognised.
- Purpose grouping, so training and answer-time fetches are separate.
- Error detail. A 403 and a timeout need different fixes, and plain-language explanations save engineering time.
- A link from crawl to citation. Knowing a bot read a page is half the story; knowing whether that page then got cited is the useful half.
- Setup that does not need a developer for a week. CDN integrations (Cloudflare, Vercel, Fastly, CloudFront) or a WordPress plugin are the common routes.
Alternatives to Brandlight with crawler-log capability
Promptwatch
Promptwatch is the option here where verified crawler logs are a core part of an end-to-end AI visibility platform rather than an add-on. Its AI crawler logs (Agent Analytics) record IP-verified visits from GPTBot, OAI-SearchBot, ChatGPT-User, ClaudeBot, Claude-User, Claude-SearchBot, PerplexityBot, Perplexity-User, Google-Agent, Meta-WebIndexer, MistralAI-User and others. Spoofed bots are filtered out by checking each visit against the operator's published IP ranges.
What makes it more than a log viewer is what sits next to it. You see which pages bots read, the errors they hit, and the crawl-to-citation path with a citation rate per page, so you can tell an access problem from a content problem. Visitor analytics then show whether AI-referred visits convert, and the Action Board turns gaps into a prioritised to-do list. The Content Agent can write and publish fixes to WordPress, Webflow, or Framer, and Page Tracker checks whether the new page gets crawled and cited.
Setup takes minutes through Cloudflare, AWS CloudFront, Fastly, Vercel, Netlify, Akamai, Google Cloud CDN, a custom HTTP endpoint, or the official WordPress plugin.
Plans, as listed on the pricing page (confirm there): Essential is $95/mo but has no crawler logs. Professional at $245/mo includes 25M crawler logs, Business at $579/mo includes 100M, and agency plans start at $199/mo with 10M. Promptwatch also has a 7-day free trial on monthly billing and a free AI visibility report if you want a quick look first.

DarkVisitors
DarkVisitors is a specialist for tracking AI agents, bots, and LLM referrals hitting your website. It is a reasonable pick if bot analytics is the whole job and you already have a separate visibility tracker. You will not get prompt monitoring, sentiment, or content workflows from it, so you end up stitching two tools together. Check their documentation for how they verify bots.
Botify
Botify is an enterprise SEO and GEO platform with a long history in log-file analysis for search engines. If your team already lives in Botify for technical SEO on a very large site, its crawler data may cover part of this need. I would verify how it handles AI-specific bots and IP verification before assuming it matches a purpose-built tool.
Profound
Profound is one of the best-known enterprise AI visibility platforms and is the usual Brandlight comparison. I did not confirm whether it offers IP-verified crawler logs, so ask for a demo of that exact feature rather than relying on a feature checklist.
Lighter prompt trackers
Peec AI, Otterly.AI, and similar tools are built around monitoring prompts and citations. From what I know of their positioning, crawler logs are not their focus, but verify on their sites.
Comparison table
| Tool | Primary focus | IP-verified AI crawler logs | Content and publishing | Best for |
|---|---|---|---|---|
| Brandlight | Brand visibility tracking | Not confirmed | Not confirmed | Teams that only need mention monitoring |
| Promptwatch | End-to-end AI visibility and GEO | Yes, on Professional and above | Content Agent, CMS publishing | Teams that want to diagnose and fix |
| DarkVisitors | AI bot and referral analytics | Verify with vendor | No | Bot analytics alongside another tracker |
| Botify | Enterprise SEO and log analysis | Verify AI-bot coverage | Limited | Very large sites already on Botify |
| Profound | Enterprise AI visibility | Not confirmed | Verify with vendor | Large brands focused on monitoring |
| Peec AI / Otterly.AI | Prompt tracking | Not a focus | No | Small teams on a budget |
A do-it-yourself route
You can get partway there without buying anything. Pull raw logs from your CDN, filter for the AI user agents above, and validate source IPs against the operator lists such as claude.com/crawling/bots.json and bing.com/toolbox/bingbot.json. It works for a single site and a one-off audit. It gets painful at scale, because you must refresh IP lists, handle operators that publish none (Bytespider), and join the result to citation data by hand.
Free starting points: Promptwatch's Agentic Readiness Check shows which AI crawlers can read your site, the AI Crawler URL Inspector tests a single URL, and the AI bots directory lists 400+ crawlers with robots.txt guidance.
How to switch from Brandlight without losing context
- Export your current tracked prompts and competitors before you cancel anything.
- Run the new tool in parallel for a few weeks. Visibility numbers rarely match across vendors because prompt sets and collection methods differ.
- Connect crawler logs first. They start collecting only once connected, and a baseline helps later.
- Compare your log mix against the public benchmark. Large gaps point to blocking.
- Fix access issues (robots.txt, CDN, WAF) before writing any new content.

Final take
If all you need is mention tracking, Brandlight may be enough. If you have ever stared at a flat visibility chart and wondered whether the bots can even reach you, you need verified logs. Of the options I looked at, Promptwatch is the one that ties those logs to citations, traffic, and content fixes in one product. Whichever tool you pick, ask for a live demo of the crawler view on your own domain, and check that it verifies IPs rather than trusting user agents.
