In 2020, we gave you some insight into our traffic numbers, focusing on the impact that global lockdowns had on our user base. Five years later, we have not only sustained that rise in users but also continued to grow steadily, so we thought we’d show you an update!

Comments in 2025

Image 1: Line graph of monthly comments on AO3 in 2020 versus 2025. Both line graphs share small dips in February, June, and September; and peaks in July, August, and October; before sharply trending upward in December. 2020 sees an additional sharp increase in April, while 2025 shows a more typical slow rise throughout the year.

In our previous post, we observed a common pattern of slight dips in user activity in June and September. This pattern still holds true: Our users left 84,278 fewer comments in June than in May, before coming back en masse in July and August. We see a significant drop in September before cresting a suspiciously Kinktober-shaped peak in October. November sees the bustle die down one more time, before we reach record highs—crossing 5 million comments for the first time—by way of our typical end-of-year holiday increase in December.

Daily page views

Image 2: Line graph showing AO3’s daily page views (in millions) starting in mid-April and ending on December 31st. Smaller spikes show higher activity on weekends than weekdays. There is one big spike to 141 million on June 1st, and two big dips to 73.7 and 72 million respectively on July 3rd and September 29th. The trend line rises slowly but steadily, crossing 110 million daily page views in mid-October.

Site traffic tends to slowly increase throughout the year with a noticeable jump in December, and we then carry that forward into the new year. Our first anomaly happens around June 1st, with several days of incredibly high page views. After consulting with our Systems volunteers, we marked this off as likely being due to a large influx of bot traffic.

On July 3rd and 4th, we ran out of rows in the database table that stores bookmarks, so we had to move them to a larger table that can hold them all! This made it so you can once again add your own bookmarks to the 647 million we already had before then. The recovery after this outage is a little higher than normal, possibly due to an influx of users downloading works to tide themselves over any future outages.

On September 29th, we had to take some planned downtime to implement an update to collections—Collection owners can now use up to ten tags of any type to describe their collection, making it easier to find collections featuring the fandoms, relationships, tropes, and other topics you enjoy.

Site traffic throughout a typical week

Image 3: Line graph of daily page views. A subsection of the above graph, more clearly showing the ebb and flow of traffic on the archive throughout the calendar week. There are five clear peaks on every weekend with the apex on Sunday. Thursday and Friday are where traffic dips to its lowest.

If we zoom in a little, we can clearly see that weekends are most of our users’ favourite time to engage with fanworks. Some may wonder about the peaks seeming to run over into Monday—our systems run in UTC and much of our traffic comes from later timezones. More North and South Americans reading late at night on Saturday and Sunday equals peaks on Sunday and Monday!

New Year’s Eve by the minute

Image 4: Line graph of requests received by our servers between 9:00 UTC on December 31st 2025 and 9:00 UTC on January 1st 2026. Requests start to rise from ~550K at 12:00 UTC, peaking at nearly 800K at 17:30 UTC before slowly decreasing back down to ~650K. Sharp, sudden drops are noticeable at 16:00 UTC, 23:00 UTC, and 5:00 UTC, with smaller drops at 0:00 UTC and 6:00 UTC.

The delayed effect described in the previous section is especially noticeable on New Year’s Eve. We receive sudden, hourly drops in requests to our servers as users in different timezones pause their reading to ring in the new year. At 16:00 UTC, 47 thousand users in UTC+8 promptly went offline before coming back in force half an hour later, giving us our first noticeable drop. The yearline swept across the globe with minor dips on each hour, before UTC+1 dropped us by a whole 50 thousand requests and UTC followed with just 43 thousand requests. By far the most severe dip occurs when UTC-5 entered 2026, with over 80 thousand fewer requests—compared to UTC-8, which only dropped us by 30 thousand requests.

Site traffic over the years

Image 5: Bar chart showing weekly traffic during the last week of November on AO3 from 2012 to 2025. Large jumps are noticeable between 2019 and 2020, 2022 and 2023, and 2024 and 2025.

To round things off, let’s have a look back through time!

We had a big jump in users this year—November 2025 saw over 146.6 million weekly page views more than the previous November. At first glance this is significantly higher than the 129 million increase we experienced from 2019 to 2020, but this is only 22% growth over the previous year as opposed to 52% because our baseline looks completely different.

We are excited to see where 2026 takes us, and it looks like we’re already starting off strong! In the first week of the year we amassed a record high of 879 million page views, a significant jump up from 816 million the week before and averaging out to ~125 million page views a day. We look forward to breaking more records with you.
