In 2025, Generative AI is reshaping how people and companies use the Internet.
Search engines once drove traffic to content creators through links. Now, AI
training crawlers — the engines behind commonly-used LLMs — are consuming vast
amounts of web data, while sending far fewer users back. We covered this shift,
along with related

(like pay per crawl) in early July. Studies from Pew Research Center (<a

</a>
already point to AI overviews — Google’s new AI-generated summaries shown at the top
of search results — contributing to sharp declines in news website traffic. For a
news site, this means lots of bot hits, but far fewer real readers clicking through
— which in turn means fewer people clicking on ads or chances to convert to
subscriptions.
</p>
<p>
Cloudflare's data shows the same pattern. Crawling by search engines and AI services
surged in the first half of 2025 — up 24% year-over-year in June — before slowing to
just 4% year-over-year growth in July. How is the space evolving? Which crawling
purposes are most common, and how is that changing? Spoiler: training-related
crawling is leading the way. In this post, we track AI and search bot crawl
activity, what purposes dominate, and which platforms contribute the least referral
traffic back to creators.

Training crawling grows: Training now drives nearly 80% of AI bot activity,
up from 72% a year ago.
</p>
</li>
<li>
<p>
Publisher referrals drop: Google referrals to news sites fell, with March
2025 down ~9% compared to January.
</p>
</li>
<li>
<p>
AI & search crawling increase: Crawling rose 32% year-over-year in April
2025, before slowing to 4% year-over-year growth in July.
</p>
</li>
<li>
<p>
AI-only crawler shifts: OpenAI’s GPTBot more than doubled in share of AI
crawling traffic (4.7% to 11.7%), Anthropic’s ClaudeBot rose (6% to
~10%), while ByteDance’s Bytespider fell from 14.1% to 2.4%.
</p>
</li>
<li>
<p>
Crawl-to-refer imbalance (how many pages a bot crawls per page that a user
clicks back to): Anthropic increased referrals but still leads with 38,000
crawls per visitor in July (down from 286,000:1 in January). Perplexity
decreased referrals in 2025 — with more crawling but fewer referrals at 194
crawls per visitor in July.

Referral traffic from search is already shifting, as we noted above and as
<a href="http://studies">
<u>studies</u>
</a>
have shown. In our dataset of news-related customers (spanning the Americas, Europe,
and Asia), Google’s referrals have been clearly declining since February 2025. This
drop is unusual, since overall Internet traffic (and referrals as well) historically
has only dipped during July and August — the summer months when the Northern
Hemisphere is largely on break from school or work. The sharpest and least seasonal
decline came in March. Despite being a 31-day month, March had almost the same
referral volume as the shorter, 28-day February.

<p>
Looking at longer comparisons: March 2025 referral traffic from Google was 9% lower
than January, the same drop seen in June. April was worse, down 15% compared with
January.
</p>
<p>
This drop seems to coincide with some of Google’s changes. AI Overviews launched in
the U.S. in
<a href="https://blog.google/products/search/generative-ai-google-search-may-2024/">
<u>May 2024</u> </a
>, but in March 2025, Google upgraded AI Overviews with Gemini 2.0, introduced AI
Mode in Labs, and
<a
href="https://blog.google/feed/were-bringing-the-helpfulness-of-ai-overviews-to-more-countries-in-europe/"
>
<u>expanded</u>
</a>
Overviews to more European countries. By May 2025, AI Mode rolled out broadly in the
U.S. with Gemini 2.5, adding conversational search, Deep Search, and personalized
recommendations.
</p>
<p>
The search-to-news site pipeline seems to be weakening, replaced in part by
AI-driven results.
</p>
<p>
Looking at a daily perspective, we can also spot a clear U.S.-election-related peak
in referrals from Google to the cohort of known news sites on November 5–6, 2024.

>
<u>In June</u> </a
>, we talked about search and AI crawler growth, and our picture of the trend is now
more complete with more data. To focus only on AI and search crawlers, and to remove
the bias of customer growth, we analyzed a fixed set of customers from specific
weeks, a method we’ve also used in the
<a href="http://radar.cloudflare.com/year-in-review/">
<u>Cloudflare Radar Year in Review</u> </a
>.
</p>
<p>
What the data shows: crawling spiked twice: first in November 2024, then again
between March and April 2025. April 2025 alone was up 32% compared with May 2024,
the first full month where we have comparable data. After that surge, growth
stabilized. In June 2025, crawling traffic was still 24% higher year-over-year, but
by July the increase was down to just 4%. That shift highlights how quickly crawler
activity can accelerate and then cool down.
</p>
<p>
As the chart below shows, crawling traffic rose sharply in March and April. It
remained high but slightly lower in May, before starting to drop in June. The
seasonal dip is similar to what we see in overall Internet traffic during the
Northern Hemisphere’s summer months (August and September are often the quietest),
though in the case of crawlers, this is likely due to reduced overall web activity
rather than bots themselves taking a “break.” Historically, activity tends to rise
again in November — as it did in 2024 for AI and search bot traffic — when people
spend more time online for shopping and seasonal habits (a pattern we’ve seen in
<a
href="https://blog.cloudflare.com/from-deals-to-ddos-exploring-cyber-week-2024-internet-trends/"
>
<u>past years</u> </a
>).

the anchor, accounting for 39% of all AI and search crawler traffic, but the fastest
growth now comes from AI-specific crawlers, though bots related to Amazon and
ByteDance (Bytespider) have lost significant ground. GPTBot’s share grew from 4.7%
in July 2024 to 11.7% in July 2025. ClaudeBot also increased, from 6% to nearly 10%,
while Meta’s crawler jumped from 0.9% to 7.5%. By contrast, Amazonbot dropped from
10.2% to 5.9%, and ByteDance’s Bytespider dropped from 14.1% to just 2.4%.

crawling volume, driven mainly by training-related activity. ClaudeBot crawling
accelerated in June, while Amazonbot and Bytespider activity slowed.

GPTBot gained 16 percentage points, Meta’s crawler rose by more than 15, and
ClaudeBot grew by 8. On the shrinking side, Amazonbot dropped 12 percentage points
and Bytespider dropped over 31 percentage points.
