Good writing isn’t written. It’s rewritten. The first draft is where the ideas land on the page, and that’s a useful achievement, but it’s rarely the version anyone should actually read.

The problem is that most people stop at draft one. They write something, run a spellchecker, and call it done. The result is content that’s technically fine but full of the small habits that make writing feel like hard work. Long sentences. Padding adverbs. Passive constructions. Words like “utilise” when “use” would land better.

This tool is the second pass. Paste something you’ve already written and it’ll surface the patterns your eye misses. Sentences that have run on too long. Words that have a simpler alternative. Phrases that are doing less work than they should.

Click on any green highlight to see a suggested replacement and swap it in with one tap. The other colours give you a visual map of what to look at. None of it is mandatory. The point isn’t to chase a clean sweep. The point is to see your writing the way a reader will, and decide what to do about it.

Try it on something you’ve written recently. Most people are surprised.

What each colour means

The tool highlights five things. Here’s what to do with each one.

Very hard sentence

Over 21 words. Most readers will lose track halfway through. Split it into two or three shorter sentences.

Hard sentence

14 to 21 words. Readable, but starting to demand more attention than it should. See if you can tighten it.

Passive voice

“The report was written by Sarah” instead of “Sarah wrote the report”. Active voice is shorter, clearer, and more direct.

Weakener or adverb

Words like “very”, “really”, “quite”, and most -ly adverbs. They water down the words around them. Try cutting them and see if the sentence improves.

Has a simpler word

Click any green highlight to see a suggested swap (“utilise” → “use”). Tap the green button to replace it with one click.


Why clarity matters more than you think

Clarity isn’t just a stylistic preference. It changes whether people finish what you’ve written, whether they remember it, and whether they act on it.

The data on this is consistent. Readable content holds attention longer, gets shared more, and converts at higher rates. NN/g research has shown that plain language can lift task completion rates by over 80% on the same content. Government bodies that have rewritten public information into plain English routinely see comprehension scores double.

For SEO, clarity feeds straight into the engagement signals Google uses to rank pages. Lower bounce rates. Longer dwell time. More return visits. None of those are direct ranking factors, but together they’re the strongest indirect signal you can send.

And for AI search, clarity is becoming a hard requirement. Tools like Google’s AI Overviews and ChatGPT preferentially cite content that’s clear, well-structured, and easy to extract. Dense, jargon-heavy writing is harder to parse and gets surfaced less often.

Clear writing is the highest-leverage thing you can fix on most websites. It costs nothing, takes a single editing pass, and improves results across SEO, conversions, and AI visibility at the same time.

Want a hand with all of this? Our SEO packages for small businesses include content optimisation as standard, alongside the technical and ranking work that gets your pages found in the first place.


Ten ways to sharpen your writing

The tool surfaces patterns. These principles help you fix them. None of them are new. Most people just don’t apply them.

01

One idea per sentence

If you find yourself using “and” or “which” to bolt two ideas together, you usually have two sentences. Let them be two.

02

Cut the warm-up

The first sentence of your first draft is almost always the throat-clearing. Delete it. The second sentence is usually where you actually start.

03

Active voice by default

“Sarah wrote the report.” Not “the report was written by Sarah”. Active voice uses fewer words and tells the reader who did what.

04

Bin the qualifiers

“Very”, “really”, “quite”, “somewhat”. They weaken the word that follows. If you mean important, say important. Not very important.

05

Vary your sentence lengths

All short sentences feel choppy. All long sentences feel exhausting. Mix them. A short sentence after a long one lands harder.

06

Use the simpler word

Use, not utilise. Help, not facilitate. About, not regarding. Big words don’t make you sound smart. They make you sound like you’re hiding something.

07

Write like you talk

Read your draft out loud. If you wouldn’t say it that way to a colleague over coffee, you probably shouldn’t write it that way either.

08

Break it up visually

Big walls of text are intimidating. Short paragraphs, subheadings, and lists give the eye somewhere to rest and the reader a way back in.

09

Edit on a different day

You can’t edit something properly five minutes after you wrote it. Sleep on it. The flaws will be obvious in the morning.

10

Stop polishing

Clarity isn’t perfectionism. At some point the rewriting stops adding value. Trust your judgement and ship.


Frequently asked questions

What is content clarity, and why does it matter?

Content clarity refers to how easy your writing is to read and understand. It’s shaped by sentence length, word complexity, voice (active vs passive), and how ideas connect to each other. Clear writing is more likely to be read, remembered, shared, and acted upon. For websites and marketing content, clarity directly affects bounce rate, dwell time, conversion rate, and how often AI search tools cite your content.

What reading grade should I aim for?

For most UK web content, aim for Grade 9 or below (the equivalent of UK Year 10, ages 14 to 15). This is accessible to around 85% of UK adults. For broader public content, aim for Grade 7 to 8. For NHS and government content, the recommendation is even lower, often Grade 6 or below. The tool above shows your current grade in the sidebar.

Why does the tool highlight passive voice?

Passive voice (“the report was written”) tends to be longer, less direct, and harder to follow than active voice (“Sarah wrote the report”). It also hides who did what, which can make writing feel evasive or impersonal. Passive voice isn’t always wrong, but it’s often a sign that a sentence could be tighter and clearer.

What counts as a weakener?

Weakeners are words that hedge, qualify, or pad a sentence without adding meaning. Common examples include “very”, “really”, “quite”, “somewhat”, “basically”, “actually”, and most -ly adverbs (“clearly”, “obviously”, “essentially”). They tend to weaken whatever they’re modifying. “Very important” is less convincing than “important”.

Should I always replace highlighted words?

No. The tool surfaces patterns to look at, not commands to follow. Sometimes a long sentence is the right choice for variety or rhythm. Sometimes passive voice is genuinely the better option (“the building was completed in 1923” doesn’t need an actor). Use the highlights as prompts to think about each choice. Keep what works, change what doesn’t.

Does this tool replace a human editor?

No. It catches mechanical issues like long sentences, weakeners, and complex vocabulary, which are useful to fix but only part of the picture. A human editor catches things this tool can’t: structural problems, weak arguments, missing context, mismatched tone, and ideas that don’t quite land. Use this for the first pass. Use a human (or a thoughtful self-review) for the second.

Does clarity affect SEO?

Yes, indirectly. Google doesn’t use a clarity score as a ranking factor, but clear writing improves all the engagement metrics that feed into rankings: bounce rate, dwell time, return visits, social sharing. AI search tools like Google’s AI Overviews and ChatGPT also tend to surface and cite clearer content over dense, jargon-heavy writing. Clarity is one of the highest-leverage SEO improvements you can make to existing content.

How is this different from Hemingway Editor?

The core idea is similar: highlight long sentences, passive voice, and complex words so you can edit them out. Our version uses British English defaults, includes a larger dictionary of UK-relevant complex words, lets you click suggested replacements directly, and is built around UK content writing conventions. It’s also free with no character limits or account required.

Can I use this tool for free?

Yes. The Content Clarity Checker is completely free, with no sign-up required, no character limits, and no restrictions on how many times you can use it. Use it as much as you like.
