SEO Content Writing: How to Write Articles That Rank

SEO content writing is the practice of creating articles that answer a specific search better than the pages already ranking, while being easy for Google and AI tools to read and trust. It starts with a keyword you can actually win, not with a blank page.

Good SEO content is accurate, structured, on-brand and published consistently. Here is how each piece fits together, and where Dex handles the heavy lifting for you.

It is writing with search in mind. You pick a query real buyers type, work out what they want, and write the page that delivers it fully. Pretty words are optional. Useful answers are not.

A ranking article usually has these parts:

A target keyword with real search volume and a difficulty you can beat.
Clear intent match. If people want a how-to, give steps. If they want a comparison, give a table.
A direct answer up top, then depth below it.
Headings phrased like real searches, so readers and machines can scan.
Facts that check out.
Your voice, so it sounds like your business and not a generic blog.

Start with the keyword, not the topic

Most small sites write about what they find interesting. Then nothing ranks. The smarter order is keyword first. That is the order Dex always works in. Dex scores every keyword by volume, difficulty and how close your site already is to ranking. A keyword with modest volume and low difficulty (say 90 searches a month and KD 12, illustrative numbers) often beats a huge term you will never reach.

Picture a local bakery. "Bakery" is brutal. "Gluten-free birthday cake near me" is narrower, closer to a purchase and far easier to win. One article per winnable search adds up fast.

Match search intent

Look at what already ranks. If page one is full of guides, a sales page will struggle. If it is full of local listings, a long essay will too. Intent decides format before you write a word.

How long should an SEO article be?

As long as it needs to be to fully answer the question, and no longer. There is no magic word count and Google does not reward padding. Still, in practice, thin pages of a few hundred words rarely cover a topic well enough to compete.

Dex writes articles of 1,000 to 3,000 words. The range is deliberate:

Around 1,000 words suits narrow questions, like a specific how-to or definition.
1,500 to 2,000 words suits most commercial and informational topics.
2,500 to 3,000 words suits broad guides where several sub-questions matter.

Check the competition, not a rule

Open the top results. Note what they cover and what they skip. Your job is to cover the same ground plus the gaps. If every competitor skips pricing or common mistakes, that is your opening.

A simple routine: list the headings of the top five pages, merge them into one outline, then add the two or three questions none of them answer. That outline is your brief.

Cut filler

Length without substance hurts. Short paragraphs, specific examples and lists keep a long article readable. If a sentence does not help the reader decide or do something, delete it.

Why does fact-checking matter for rankings and AI answers?

Because wrong claims cost you trust, and trust is what both search engines and AI tools lean on. Google says it wants helpful, reliable content, and its quality guidance emphasizes experience, expertise and trustworthiness. An article full of invented stats or outdated advice works against that.

AI search adds another layer. Tools like ChatGPT, Perplexity, Gemini, Claude and Bing pull from pages that state things clearly and consistently. Vague or contradictory pages are harder to quote. Dex optimizes for AI search visibility as well as Google, though no one can guarantee a citation.

What fact-checking looks like in practice

Verify every number, date and named source.
Avoid claims you cannot support. Hedge honestly when data is uncertain.
Label examples as examples. An illustrative figure is fine if you say so.
Prefer plain, specific statements over vague ones, since they are easier for readers and AI tools to quote correctly.
Update old articles when facts change.

Dex fact-checks every article before it goes out. That is the rule, not a bonus. In review mode, you can still read it first.

The business risk

A dentist publishing wrong treatment info or a shop quoting wrong shipping rules does real damage beyond rankings. Accuracy protects customers as well as traffic.

What is a content score, and how do you use it?

A content score is a quick quality rating for an article. In general, a content score reflects how well a piece covers its topic and matches what the keyword calls for. Dex puts a content score on every article, so you do not have to guess whether a draft is strong.

How to use it

Check it before publishing. A low score is a flag to look closer.
Compare across articles. Patterns show which topics and formats you cover best.
Treat it as a guide, not a guarantee. A high score does not promise a ranking. Competition and site history still matter.
Pair it with Search Console data. Dex reports clicks from Google Search Console, so you can see which articles actually earn traffic and which need work.

What to improve when a score is low

Missing sub-questions readers expect.
Thin sections that only skim the topic.
Headings that do not mirror real searches.
Vague answers where a specific example would help.

Fix the weakest section first. One strong rewrite usually helps more than light edits everywhere.

How do you keep your brand’s tone of voice?

Decide how you sound first, then hold every article to it. Readers can tell when a bakery blog reads like a legal firm. Consistent tone builds recognition and makes content feel human.

Write down a short voice guide:

Formal or casual? Pick one.
Words you use and words you avoid.
Sentence length. Short and punchy, or measured and detailed?
How you address the reader. You, we, or neutral third person.

Dex writes in your brand’s tone of voice, and it does this in 7 languages: English, Portuguese, Spanish, German, French, Italian and Dutch. That matters if you serve customers in more than one market, since a direct translation rarely sounds natural.

Keep a human check where it counts

Add real details only you know: your opening hours, your signature product, a local landmark. These details make content distinctive. With Dex, you can use review mode and approve the content plan before anything is written, or run full autopilot once you trust the output.

A good habit: read the first paragraph and the last paragraph of each article. If both sound like you, the middle usually does too.

Does Google penalize AI-written content?

Google has said it focuses on the quality and helpfulness of content, not on how it was produced. Its guidance targets spam, meaning content made mainly to manipulate rankings, whether a person or a tool wrote it. Low-value, mass-produced pages are the risk.

No one can promise a site will never be penalized, and no one should promise that AI-written text is undetectable. Be wary of anyone who does. The sensible approach is to publish content that earns its place.

What keeps AI-assisted content safe

Target real searches rather than churning out pages for their own sake.
Fact-check every claim.
Add depth that goes beyond what already ranks.
Keep your voice and real business details.
Review output and track what performs.

Ask one question of every page: would a customer be glad they landed here? If yes, you are on the right side of the line.
