You chart a topic's Wikipedia page views and the line falls off a cliff. Hundreds of thousands of readers one month, almost nothing the next. Did everyone suddenly lose interest?
Almost never. The article was renamed. This is the most common thing that goes wrong when you chart page views, and it's easy to fix once you know. I hit it myself while building my free Google Sheet, the Wikipedia Trends Tracker.
The short answer
Wikipedia records page views under each article title separately. When an article is moved to a new title, new readers are counted under the new title and the old title becomes a redirect, so the old title's line drops to near zero. To see the full history, chart both the old and new titles and add them together.
Real examples
All numbers are human readers on English Wikipedia, from Wikimedia's pageviews API.
Claude, 2026
The article "Claude (language model)" had about 235,000 readers in May 2026 and about 26,000 in July. Meanwhile "Claude (AI)" went from about 100 readers in May to about 148,000 in July. Same article, new name, moved in June. Chart only the old title and Claude looks like it collapsed. Chart only the new one and it looks like it came from nowhere.
Bard becomes Gemini, 2024
"Bard (chatbot)" had about 144,000 readers in January 2024 and about 2,000 in March. "Gemini (chatbot)" started in February 2024 with about 93,000. Google renamed the product, and Wikipedia followed. It happened again in late 2025, when the article moved to "Google Gemini".
Padel, 2022
"Padel (sport)" was renamed to "Padel" in 2022. Since then, the old title gets a couple of thousand readers a month, and the new title has all the growth. You can see both added together on the Pickleball vs Padel page.
How to tell it's a rename and not a real drop
- The drop is in one month. Real interest fades over months. A rename is a cliff.
- The old link still works. Open the old Wikipedia address. If it lands on an article with a different title and a small "Redirected from" note at the top, it's been moved.
- The talk page or history says so. On the article, open View history and look for a "moved page" entry with the date.
How to fix it in Google Sheets
- Get the free template from the Trend Tracker page and make a copy.
- On the Controls tab, paste the new title into Page 1 and a steady topic into Page 2 as a baseline. Set Range to All time and Daily or monthly to Monthly.
- Click Fetch views + chart with Include old names on No. That's the cliff (or the line coming from nowhere).
- Set Include old names to Yes and fetch again. The sheet adds the old title's views to the new one, so you get one continuous line.
When you're comparing two different topics and one has been renamed, mention it next to the chart. Our ChatGPT vs Claude page adds both of Claude's titles together for that reason, and Zelle vs Venmo does the same for Zelle.
Other reasons a line can drop
- The current month. It's still being counted, so the last point is always low. Ignore it.
- A disambiguation page. If the title you used now points to a list of meanings, readers are being sent somewhere else.
- A merge. Sometimes two articles are combined. The one that disappears drops, and the survivor gets its readers.
- Real decline. It does happen. But it looks like a slope, not a cliff.
FAQ
Do Wikipedia page views carry over when an article is renamed?
No. Views are stored per title. The history stays with the old title, and new views go to the new one.
How do I find an article's old title?
Open the article's View history and look for "moved page" entries, or check whether an old link redirects to it.
Why did my chart have a gap in the middle?
Usually a month with no data for that exact title, or a title with special characters that wasn't encoded. Copy the article address straight from your browser to avoid it.
Chart old and new titles side by side. Get the free Wikipedia Trends Tracker and paste both links.
