Every year keeps its colour across every chart.│ ChatGPT, 30 Nov 2022

320 of carwow's own blog posts, press releases and announcements, 2015 to 2026, measured sentence by sentence, 91 of them recovered from the Internet Archive. How the writing has moved over the years, how it compares with 6 other motoring brands, and what it sounds like in its own words.

03 · Before and after

2019 to Nov 2022 against 2024 to 2026

The same measures on 67 pages from before ChatGPT launched and 173 pages from 2024 on. A change here is a change in style. It does not show how any page was written: people used every one of these words and shapes long before 2022, and SGR-011 found most of the shift across brands was a trend already under way.

Every chart is centred on its before value and shares one relative scale, so a longer bar means a bigger percentage change; the values themselves are in different units and do not compare. Before = 2019 to Nov 2022 (67 pages); after = 2024 to 2026 (173 pages). Method: SGR-011.

08 · Method

How this was measured

The pages

carwow's own blog posts, press releases and announcements, fetched from the live site in 2026 and from the Internet Archive for 2015 to November 2022. Homepages are shown as captures; product and help pages are not measured.

The measures

Code counts from ScriptGrain’s writing instruments: sentence length and rhythm, contractions, pronouns, punctuation, long words, and three published lists of AI-associated words. No AI model reads or judges any page.

What it cannot say

These measures describe style. They cannot tell who or what wrote a page, and nothing here says or implies that any brand used AI to write.

Sample sizes

Every number carries its page count. Years under 10 pages, and before-and-after comparisons with under 10 pages on a side, are shown as context only.

Sentence length
Average words per sentence.
Sentence rhythm
How much sentence length varies (standard deviation over mean). Higher reads less even.
Contractions
Contractions (we're, you'll, it's) per 1,000 words. A rough gauge of how conversational the writing is.
"You"
Share of I/we/you pronouns that are "you": how much the writing addresses the reader.
"We"
Share of I/we/you pronouns that are "we": how much the writing talks about the organisation.
Questions
Question marks per 1,000 words.
Exclamations
Exclamation marks per 1,000 words.
Long words
Share of words with seven or more letters.
Em dashes
Em dashes per 1,000 words.
AI-associated words
Words from SGR-007's three AI-associated lists, per 1,000 words. These are style markers that people used long before ChatGPT; a higher rate says nothing about who or what wrote the page.
AI-era marketing words
Marketing words that became more common in AI-era copy (seamless, elevate, unlock...), per 1,000 words. A style measure only.
Quieter LLM-favoured words
Everyday words language models are known to over-use, per 1,000 words. A style measure only.
AI-associated sentence shapes
Sentence patterns such as "not just X, but Y", found by ScriptGrain's cliche checker, per 1,000 words. A style measure only.
Page length
Average words per page.
