How do software companies with UK sites write? 16 brands measured against nine other sectors
SGR-016, conducted 2026-10-05. Analyst: Jack Stovell, founder, ScriptGrain.
Question: How does the writing of software companies with UK sites differ from other sectors' on counted habits such as sentence length, "you", contractions and AI-associated words, and how has it changed since 2015?
Summary
Background. SGR-010 measured how 117 UK brands in 10 sectors write, and SGR-011 tested whether that changed after ChatGPT. This report takes one sector, software companies, and sets its writing against the other nine.
What we did. We measured 3,422 pages from 16 software companies with UK sites: 2,313 blog posts and 1,109 press releases and announcements, 969 of them from the Internet Archive. Every measure is a count made in code. Each brand counts once, however many pages it has.
What we found. Against the other nine sectors, software companies wrote with more AI-era marketing words (1.80 against 0.76, highest of 10 sectors); more AI-associated words (2.12 against 1.01, highest of 10 sectors); longer pages (1,512 against 1,033, 2nd highest of 10 sectors); more em dashes (3.04 against 2.16, highest of 10 sectors). Software companies' most distinctive words were "product", "team", "teams", "marketing", "project", "design".
What it means. These are sector averages over brands. On 8 of the 12 habits the middle half of the sector's own brands sits wholly to one side of the other sectors' average, so on those habits at least three in four of its brands sit on the same side. The report describes; it was not set up to test a hypothesis.
Key numbers
- Software companies with UK sites averaged 1.80 AI-era marketing words per 1,000 words, against 0.76 in the other nine sectors (highest of 10 sectors; ScriptGrain, 2026; 16 brands, 3,422 pages).
- Software companies with UK sites averaged 2.12 AI-associated words per 1,000 words, against 1.01 in the other nine sectors (highest of 10 sectors; ScriptGrain, 2026; 16 brands, 3,422 pages).
- Software companies with UK sites averaged 1,512 words per page, against 1,033 in the other nine sectors (2nd highest of 10 sectors; ScriptGrain, 2026; 16 brands, 3,422 pages).
- AI-associated words in software companies' writing peaked in 2024 at 4.07 per 1,000 words (ScriptGrain, 2026; 16 brands, brand-weighted by year).
Sample
16 software companies with UK sites from ScriptGrain's brand deep corpus (October 2026): blog posts, press releases, product announcements and information packs from their own sites, fetched on 4 and 5 October 2026, plus archived pages from 2015 to November 2022. 3,422 pages measured.
- Written by the brand on its own site or newsroom, in English
- At least 150 words of main text
- Not a link list or menu
Method
Plan: the sector reports were set out in the series pre-registration (docs/research/brand-series-preregistration.md section 6) before any page was measured: the SGR-010 tables for the sector against all other sectors, and the SGR-011 measures within the sector, exploratory, with intervals.
Text and measures: as in SGR-010. Each page's main content reduced to plain text and counted in code.
Weighting: each brand's pages are averaged first, then brands, here and for the other nine sectors.
Years: pages with a date from their metadata, structured data or URL, or an archive capture date. A year is shown for the sector when it has 10 or more pages.
Before and after: SGR-011's rule, inside the sector: a brand channel with at least 10 dated pages from 2019 to November 2022 and 10 from 2024 on.
Variables measured
- Words per sentence
- Sentence length variation
- Long words (7+ letters)
- "You" share of I, we, you
- "We" share of I, we, you
- Contractions per 1,000 words
- Questions per 1,000 words
- Exclamation marks per 1,000 words
- Em dashes per 1,000 words
- AI-associated words per 1,000
- AI-era marketing words per 1,000
- Words per page
What each measure means
- Habits
- Words per sentence and its variation (standard deviation over mean), the share of words of seven letters or more, the "you" and "we" shares of all I, we and you words, and contractions, questions, exclamation marks and em dashes per 1,000 words, all counted in code by the same functions as SGR-010.
- AI-associated words
- Uses per 1,000 words of three published word lists: words studies of scientific writing found language models over-use, words publicly mocked as ChatGPT tells, and AI-era marketing words ("seamless", "elevate", "unlock", "empower"…). AI-era marketing words are the last list on its own. The same measure as SGR-007. Humans use all of these words; the rate says nothing about who wrote a page.
- Other sectors
- The brand-weighted average of the other nine sectors' brands: banks, energy, telecoms, software, supermarkets, travel, insurance, fashion, charities, and food and drink, less this one.
- Rank
- Where the sector's brand-weighted average sits among all 10 sectors, 1 being the highest.
- Brand range
- The 25th to 75th percentile of the sector's brand averages: the middle half of its brands.
- Distinctive words
- Words this sector uses more than the others, ranked by a log-odds score. A word counts only if at least three of the sector's brands use it and no one brand supplies more than half its uses; brand names and page furniture are removed.
- 95% interval
- From 2,000 bootstrap resamples of the sector's brands.
Findings
- More AI-era marketing words than other sectors (1.80 against 0.76 (+137%)): Software companies ranked highest of 10 sectors. The middle half of the sector's brands ran from 1.21 to 2.39.
- More AI-associated words than other sectors (2.12 against 1.01 (+111%)): Software companies ranked highest of 10 sectors. The middle half of the sector's brands ran from 1.50 to 2.92.
- Longer pages than other sectors (1,512 against 1,033 (+46%)): Software companies ranked 2nd highest of 10 sectors. The middle half of the sector's brands ran from 1,057 to 1,654.
- More em dashes than other sectors (3.04 against 2.16 (+41%)): Software companies ranked highest of 10 sectors. The middle half of the sector's brands ran from 2.27 to 3.79.
- AI-associated words by year (Peak in 2024: 4.07 per 1,000 words): Across all 10 sectors the peak was 2024 (2.16). Software companies ranked highest of 10 sectors on these words over the whole period.
- Press releases against the same brands' blogs (Longer sentences (+1.4 words, 95% interval 0.3 to 2.4); less "you" (−25.6 points, 95% interval −35.5 to −15.1); more AI-associated words (+0.98, 95% interval 0.60 to 1.33)): 15 software companies had at least five of each. Positive numbers mean the press releases had more.
- Before and after ChatGPT (exploratory) (1.84 to 2.41 AI-associated words per 1,000; ten brands): Ten of the 16 software companies had at least 10 dated pages in one channel both before ChatGPT (2019 to November 2022) and from 2024. In that writing, AI-associated words went from 1.84 to 2.41 per 1,000 words (+0.57, 95% interval −0.14 to 1.14).
- One voice across channels (from SGR-012) (Same brand, same channel 79; same brand, other channel 66; rival, same channel 75 (out of 100)): Five software companies qualified for SGR-012. Here a rival's page in the same channel scored closer than the brand's own other channel.
What this study does not show
- That any page, or any brand, used AI to write. Word counts show style; humans used these words before ChatGPT and keep using them.
- That voice measurement, ScriptGrain's or anyone's, can tell whether a text was written by AI. Nothing in this study tests that.
- That one software company's writing is better than another's, or that the sector's habits work. Nothing here measures readers, sales or search.

Limitations
- 16 brands. A sector average can move with one or two brands; the brand range column shows the spread.
- Pages are what each brand publishes on its own sites. Brands that publish little have few pages.
- Counts of surface habits only. They describe style, not quality.
- Descriptive. Differences from other sectors are reported without significance tests.
