Bot vs human traffic

One funny thing I've discovered as a result of certificate transparency logs is that the second your host gets given an SSL cert, you are immediately blasted with ai crawlers.

I put a project online - it was online for a month, and the second I added an SSL cert it went from 0 traffic to 1000 requests/min.

It's a silly metric. There could be only one master bot that pings every known endpoint multiple times a second, and that would probably surpass all human activity, too. It doesn't really tell us much about intention or the ability to masquerade as humans.

Where I would start to worry is if there's evidence that bot access patterns are starting to become harder to distinguish from human access patterns, which would suggest that they are, in fact, mimicking or masquerading as humans. I don't care how many search bots are indexing web content, but I do worry about how many social bots are attempting to manipulate or mislead people.

“First time”

The graph seems like it only goes back to April 27 and on that day it was 57% bot…

> Percentage of HTTP requests classified as bot (automated) or human. Filtered to HTML responses, representing web page traffic.

(Emphasis mine)

I realize that this is likely an inherent limitation, but there is a difference between "bot vs human traffic" and "traffic that CF thinks is bot/human". Every time CF blocks me, I assume it claims I'm a bot in this chart.

According to the Thales Bad Bot Report, in 2025 >53% of traffic came from bots. 2024 was 50 - 50, and in 2013, it was measured at 43%.

AI-driven* bot activity has increased more than tenfold however in the past 12 months so I'm confident this will grow to a very solid majority.

If they were truly this accurate at identifying sources of bot traffic, you'd think they'd be better at blocking them without inconveniencing the rest of us.

For the first time? No way. People were saying this 5, 10, 15+ years ago.

This feels like a vibe-coded dashboard that someone made just because they could and with AI it is much cheaper/quicker to create. But they didn't actually put too much thought into how it would/could actually be used. This doesn't really provide much value over "well that's kind of interesting to know". There aren't really actionable points that one can take from looking at these charts.

Some of my opinion above is formed from my own experience making similar charts just because I wonder what something would look like graphed out :)

Given how many rounds of captchas I have to fight through, I'm not sure if these numbers are accurate.

Bot traffic

  Share of HTTP requests
  
  Ranking   Location   Percentage
  1.        Gibraltar    92.0%
  2.        Iran         76.9%
  3.        Singapore    76.4%
  4.        Ireland      72.9%
  5.        Netherlands  68.8%

Lol, what is happening?

I was tracking this as part of an older job and this has been the case for some years now - started around the Covid time with all the scalping bots etc and has just been building up.

This sorta mirrors the early-mid 2010's when people[1] were worried about how much of the internet was streaming traffic.

On the Traffic page it is showing Bots more than Human,

but on the Bot page it's the opposite: 65.9% Human vs 34.1% Bot

Dead internet theory

Automated systems that don’t sleep and are often programmed to aggressively scrape and are limited only by compute capacity outstripped humanity? I am not surprised by this at all.

Saw this play out firsthand this week. Launched a small developer tool and within 48 hours had traffic from 38 countries — Netherlands and Singapore near the top, which matches the bot-heavy regions in this data.

The SSL cert observation in another comment here is accurate too. The second a domain goes live it gets discovered.

Any thoughts on why ~30% of HTTP request are in US? I know we had first mover advantage for awhile but I'd expect this to have been diluted by larger populations by now. It doesn't appear to be AI/bot driven either.

Not shocking if CF is now trying really hard to keep me out of the internet

Would love to see it go further back and some meaningful metric of how much is web scrapers vs bots.

In this graph, "api request" traffic looks like to be conflated to be "bot".

Can bot traffic cause ad revenue to go up by any chance? Or false clicks that cost advertisers?

Given how most of the internet is on mobile, I wonder how much that would skew this.

Dead internet theory gaining more credibility with every passing day.

I'm looking forward to the fraud lawsuites for ad companies

Only for HTML content. Total traffic would have been surprising.

CF posts metrics which reinforces their business... shocking

OP: please add [2012] to the title

Ha! More electricity than candles and gaslight. More steam power and automobiles than horses…more bicycles and pedestrians than cars and trucks—-well.

Maybe "first time on a weekday"? Asit seems it's been above 60% every weekend since they started monitoring it.

I think it’s meant as “for the first time in history..”. Not today in particular, but as a milestone.

Given how many rounds of captchas I have to fight through, I'm not sure if these numbers are accurate.

Funny how I get captcha looped with my adblocking in firefox but you can just get through easily with a few puppeteer plugins controlling headless chrome.

You have to fight, for some bots it might not be a real fight anymore...

That's why the human traffic numbers are so low. They just get frustrated with the CAPTCHAs and close the tab. So maybe accurate after all???

Trivial to bypass though, the big players just haven't gone that far yet.

Captchas are part of the traffic. ;)

Gib probably has a handful of servers scraping, but the place is so small, it almost it eclipses normal traffic

I do understand why all of those bot scores are so high. But netherlands? Are there big datacenter providers I dont know of that are used by bots?

I've been thinking of using wildcard certs for Caddy in regards to this.

Make a new certificate, let crawlers blast you and add those IPs to a block list.

Today AI crawlers, years ago vulnerability scanners from Russia or China.

Either way! People monitor cert registries for targets.

Network effect feedback. Cheap hosting in the US because servers are there, more servers are there because of demand for hosting. AWS is there - similar reasons. Big Tech had more time to develop there and eclipsed other countries' tech.

my first guess would be a decent chunk of things bot operators want to scrape are in the US. might as well have your bot nearer to the source.

Is it not just a case of most of their clients being US based?

Looking at the verified bots section, all the top bots are web crawlers, which have been around for decades, to your point.

Thales Bad Bot Report categorizes the traffic between "good" and "bad" bots.

I would add that AI dramatically blurs the line between legitimate and malicious, and the intent generally speaking.

In regards to social bots, there's a 2024 study of over 1 million accounts on X and over 60% were found likely to be bots. Curiously, when Musk took over Twitter, the "Blue Checkmark" became something that can be bought for several bucks a month (with crypto, even), without any sort of verification.

I do sometimes get blocked as a bot. I have no idea how many false positives there are, but there are some and CF does assume there are none in all their numbers (e.g. email saying they block x bots).

Cloudflare are more likely to be undercounting bots - they don't really pick up many of the modern browser-driven bots and crawlers.

I'm also quite skeptical of the IP databases ability to get this correct in border regions. All of Gibraltar is, necessarily, near its borders.

Make a new certificate, let crawlers blast you and add those IPs to a block list.

these old network security techniques don't really work anymore. the common bots are at known IP ranges, the problem bots are all on datacenter + residential proxies.

In my experience, these aren't the crawlers from legit companies, so they have infinite IPs via residential botnets/proxies.

Even if you use a common subdomain, anecdotally I get orders of magnitude less bot traffic than not using a wildcard cert.

I mean, just for a reference point, 2013. 2013 was the first year they did the report.

Yes, one of my favorite memories of CF is getting blocked and then almost immediately getting an email where they bragged how many bad actors they blocked. Like... do you? Are you sure?

I'm quite happy to believe that it's unreliable in both directions.

The original submitted title (when I commented) was something like "Bots overtake human traffic for the first time".

Even if you use a common subdomain, anecdotally I get orders of magnitude less bot traffic than not using a wildcard cert.

Why would blocking those be a problem?

because you are blocking all of Comcast, Verizon, T-Mobile, British Telecom, ....

at the end you have blocked every network with human visitors and only datacenter IPs can access your site.

The proxies rotate IP every day, so you either have ineffective blocking or you block the whole network.

there are 150M+ of them and you'll be taking out a lot of human users with it

modern blocking is behaviour / heuristic based
