Seonix
The tool that audits, writes and publishes your site's SEO on its own.

Is it worth trusting your blog to such a new tool?
our rating
I tested it the simplest way possible: pasted my site's URL into the free audit and got specific technical alerts — nothing generic — in under two minutes. That part works, and works well. The problem is I couldn't find a single third-party review about the rest of the promise (writing and publishing on its own): not on Reddit, not on G2, and the official WordPress plugin has fewer than 10 active installs. It's a real product with a good idea, but I wouldn't put my whole company blog on autopilot without watching the first few weeks closely.
Tested and checked against official sources on August 20, 2026.
In favor
- Combines technical audit, article writing and automatic publishing into one flow — most SEO competitors only cover one of those at a time
- Covers traditional SEO (Google) and also tracks whether your site shows up in ChatGPT, Gemini and Perplexity answers
- The free plan already delivers a full technical audit, speed monitoring, and a Search Console and GA4 connection, at no cost
- Publishes straight to WordPress, Shopify, Wix, Webflow and Ghost, with content generated in more than 50 languages
Against
- No public third-party review exists yet — not on G2, not in SEO blogs, not on Reddit
- The official WordPress plugin has fewer than 10 active installs and no ratings on record — the user base is still tiny
- The only paid plan with public pricing (Starter) caps out at 30 articles a month and 1 site — anything more is by quote only
- The trial already charges $1 upfront — it isn't a 100% free trial the way many competitors offer
An SEO hire that audits, writes and publishes on its own
Seonix is an AI-powered SEO tool. You paste your site's address, it runs a full technical audit, builds a content plan based on what your audience actually searches for on Google, writes the articles and publishes them straight to your WordPress, Shopify, Wix, Webflow or Ghost — without you opening a text editor. The difference from a regular SEO agency: it also measures whether your site shows up in answers from tools like ChatGPT and Gemini, not just Google.
Every month without a new post is traffic your competitor keeps
You know you should be posting new content on the company blog. But writing a decent SEO article — researching the keyword, structuring it, editing it — eats up the whole afternoon, and the task always loses to something more urgent.
That's what Seonix's entry plan publishes on its own, audit and keyword research included. You don't write — you review. The actual sitting-down-to-write part comes off your list.
Who would turn on Seonix this morning
The company site has been sitting untouched since launch. Run the free audit, find out what's blocking Google, and let the entry plan publish one article a week on its own.
Runs a store on Shopify or Wix and knows the category pages should be optimized, but there's never time. Connects the store and lets Seonix handle the content side.
Manages the blog for 2 or 3 small clients with no writing team. Uses the audit to prioritize what to fix first on each account.
From your site's link to the first published article
- Go to seonix.ai and paste your site's URL
On the homepage, click "Analyze my site" (or "Get my free analysis") and enter the address of the site you want audited.
- See the free audit results
Within minutes it lists technical SEO issues, site health and speed, and builds an AI-generated business profile.
this part is free, no paid plan required - Choose to trial or subscribe
For it to write and publish on its own, start the 3-day trial for $1 (click "Start my $1 trial") or subscribe directly to Starter through "Get started".
- Connect the site where it will publish
For WordPress, install the official "Seonix SEO" plugin, open the Seonix menu in your WordPress admin, and click "Connect to Seonix". Shopify, Wix, Webflow and Ghost connect natively from inside the Seonix dashboard.
- Let it build the content plan
Based on the audit and your niche's keywords, it puts together the article topics most likely to bring traffic.
- Turn on auto-publish and keep an eye on it
Articles go out on the schedule you set. Review the first few before letting it run fully on autopilot.
A ready prompt to guide the content plan
My company works in [your industry] and serves [your city or region]. My ideal customer usually searches Google with questions about [your business topic] before deciding to buy. Prioritize the content plan around topics that answer those questions with buying intent and a local SEO focus, before any generic "about the company" article.
Paste this into the business description field or the project's initial briefing, if Seonix asks for that context during setup — it helps the AI prioritize the right topics instead of generating generic content.
What actually drives traffic — and what stalls the process
Do this
- Start with Free — run the full audit before paying anything, to see if the alerts actually make sense for your site.
- If your site already runs on WordPress, Shopify or Wix, use the native integration — it's the flow the tool was built for.
- Treat Starter's 30 articles/month as a ceiling, not a target — publish fewer at first and review each one.
Avoid
- Looking for a Portuguese tutorial video — none exists yet; all official documentation is in English.
- Assuming Enterprise has a fixed price — it's by quote only, no published value on the site.
- Leaving the whole blog unsupervised from day one — it's a new product, with no third-party track record validating what it publishes.
Run the free audit on your site right now
Go to seonix.ai, paste your site's URL (or one you manage) and run the free analysis.
You've succeeded if you get at least 3 specific technical issues for your site — not generic ones — in under 2 minutes.
Does it fit your business?
It's worth it if you…
- Run a small business with a stalled site and know you should be posting content, but never find the time to write
- Already use WordPress, Shopify, Wix, Webflow or Ghost and want automatic publishing without copy-pasting articles
- Want to start showing up in ChatGPT and Gemini answers too, not just Google
Think twice if you…
- Manage several sites or brands — you'll land straight on Enterprise, by quote only, no fixed price
- Will need more than 30 articles a month on a single site — that's exactly where Starter caps out
- Want the safety of a product tested by lots of people — it's too early for that, still with no public reviews
What it costs to outsource SEO to AI
The audit is genuinely free. What's paid is the writing-and-publishing part — and Seonix charges in dollars only, with no local-currency option.
$0 — full SEO audit, health and speed monitoring, AI business profile, AI-search readiness check, Search Console and GA4.
$1 — 3 AI-published articles, to test before subscribing.
$49/mo — 1 site, 30 AI articles a month, 50 AI edits a day, 5 cover images a day, auto-publish, keyword research and support.
By quote — unlimited projects and content generation, a dedicated account manager, and custom integrations.
Important detail: all prices are in US dollars, as shown on the official pricing page — we don't convert them. Confirmed at seonix.ai/pricing in August 2026.
Other paths for AI-powered SEO
We couldn't find a direct, third-party-tested comparison against Seonix — it's too new for that. But if you're weighing AI SEO tools, the names that come up most often in this space are worth mentioning: Surfer SEO, focused on optimizing content you've already written based on what already ranks; Semrush, a full SEO and paid-media suite, more robust and more expensive; and Ahrefs, a reference point for backlink analysis and keyword research. None of the three write and publish content on their own the way Seonix proposes — the trade-off is a more mature, better-tested tool for a generally higher price and no auto-publishing.
Questions from someone who's never heard of Seonix
Is Seonix really free?
There's a real Free plan with a full SEO audit, site health and speed monitoring, an AI-generated business profile, and a connection to Search Console and GA4 — at no cost. But for it to write and publish articles on its own, you need to start a 3-day trial for $1 (3 published articles) or subscribe directly to the Starter plan, at $49 per month.
Do I need to enter a credit card?
For the $1 trial, yes — it's a real 3-day charge, so a card is required. For the Free plan (audit only), the site doesn't make it clear whether a card is required at signup; if you'd rather not risk it, start with the audit and decide later whether to move to the paid trial.
Does it work in Portuguese?
Content generation works in more than 50 languages, including Portuguese — so the articles it writes can come out in Brazilian Portuguese. What we couldn't confirm is whether the dashboard itself has a translated interface; Seonix's own website is in English.
Does it work on mobile?
It's a web tool, so it opens in your phone's browser with nothing to install. But setting up your site, configuring the audit, and reviewing articles are more comfortable tasks on a computer screen — it isn't built for daily mobile use.
Do I need to know how to code?
No. The WordPress connection is done through the official plugin ("Seonix SEO" — install it like any plugin and click connect), and Shopify, Wix, Webflow and Ghost all have native integrations. No code required.
Can I cancel anytime?
Yes, the site states this directly: no long-term contract, and cancellation is done right from your account settings, at any time.
