What does SEO Writer do?
Content brief
Outline, target length, topics and phrases, entities, questions, a fact bank with sources, content gaps, FAQ ideas, schema suggestions and internal links from your audited pages.
Your experience built in
The brief asks 3–5 questions about your first-hand experience, and the writer uses your answers, your business details and your tone.
Fact-check and originality check
Every number must match the fact bank or your own input, or it's flagged "Check this". Paragraphs that overlap too much with a source page are rewritten.
Scores and editor
SEO, Semantic, Originality, Facts, Readability, E-E-A-T and Helpfulness scores, each with reasons, plus section actions such as expand or rewrite.
Publish and repurpose
Copy as HTML, export, publish to a connected WordPress site, or turn the article into social posts with Join Postly.
How SEO Writer works
Create a brief
Enter a keyword, location and language, plus any competitor URLs you want analysed.
Answer the experience questions
Add the details only you know: prices, results, examples, opinions.
Write, review and publish
The article is written in the background; review the flagged parts, then publish.
Where does the data come from?
Briefs are built from the top pages in the Join Postly Index plus up to 10 competitor URLs that JoinPostlyBot reads when you create the brief. Writing uses open AI models: on Free the model runs in your own browser, on paid plans it can run on Join Postly's servers.

SEO Writer FAQ
Does the Postly Rank writer copy text from other websites?
No. It analyses what the strongest pages cover, then writes new text. Every article is compared with the pages it analysed, and paragraphs that share too much wording are flagged and rewritten.
How does the SEO Writer handle facts and numbers?
Every figure in the draft must match a fact found in the analysed pages or a detail you entered yourself. Anything else is marked "Check this" so you can confirm or remove it before publishing.
Can I publish SEO Writer articles to WordPress?
Yes. Connect your WordPress site in Join Postly and publish the article as a draft or post. Title, slug, content and excerpt are sent; JSON-LD is shown for you to copy because WordPress strips scripts for most roles.
