Style consistency

What style consistency covers

Many writing decisions have more than one acceptable answer; consistency is choosing one and applying it everywhere. Do you write "email" or "e-mail", "website" or "web site", "log in" (verb) or "login" (noun)? Is it "9 a.m." or "9 AM", "5%" or "5 percent", "Sept. 1" or "September 1"? Do headings use title case or sentence case? Is the product called "the Dashboard" or "the dashboard"? None of these is right or wrong in isolation, but mixing them within one site signals carelessness.

Editorial teams capture these choices in a style guide — a house standard, often built on a base like the Chicago Manual of Style or AP, plus a project-specific word list for terms unique to the organization. Consistency then means conformance to that guide. Where no formal guide exists, consistency still applies: the text should at least agree with itself.

Why it matters for website copy

A website is written by many people over a long time — different authors, different pages, copy migrated from old systems — so inconsistency creeps in naturally. One page says "sign up", the next says "signup"; the homepage uses the Oxford comma, the about page drops it; a feature is "Auto-Save" in one place and "autosave" in another. Individually trivial, these inconsistencies accumulate into a site that feels disjointed and less trustworthy, and they can confuse readers when the same thing is named two ways.

Consistency is harder to check automatically than spelling, because it is relative: the tool has to notice that two pages disagree, not that either is wrong on its own. Verant flags style problems as one of its six kinds of copy issue — including phrasing that reads inconsistently from one page to the next — quoting the exact text so a reviewer can decide which form to standardize on. It does not, however, enforce a configured house style guide or terminology database; there is no custom rule set to train, so the judgment is about readability and internal agreement rather than conformance to a specific external standard.

Common mistakes

The most common mistake is having no agreed convention at all, so each author silently picks their own and the site drifts. Another is keeping a style guide that nobody consults, so the document and the live copy diverge. A third is fixing inconsistency on the visible pages while ignoring the long tail — older posts, templated pages, and migrated content — where the oldest, most divergent choices survive.
