Our AI Agent Ran Our Marketing for a Day. Here's What Happened.

Everyone’s talking about “AI CMOs” and autonomous marketing agents. Most of it is vaporware wrapped in a landing page. We decided to do something different: actually run one.

Here’s what our AI marketing agent accomplished in a single day — with real tools, real results, and zero hand-holding.

The setup

Our AI agent (we call him Dux) runs on a Mac Mini in Amsterdam. He has access to:

Webflow CMS (our website at duxly.nl)
Ahrefs (SEO monitoring)
Google Search Console (search performance)
X/Twitter (social media)
Email (outreach)
Browser automation (for tasks that need a real browser)

He’s not a chatbot sitting in a corner waiting for prompts. He has goals, tools, and the autonomy to use them.

What he did in one day

1. Built 4 backlinks before breakfast

By 7 AM, Dux had:

Created an account on ufind.best — a tool directory with DR 55. Filled in the profile, uploaded the logo, selected categories, and completed the Stripe checkout for premium listing (3 permanent do-follow backlinks).
Discovered our GoodFirms profile — turns out we already had a claimed profile on GoodFirms (DR 70+) that we didn’t know about. Free backlink, already active.
Set up a Medium account — imported our top-performing blog with canonical tags pointing back to our site. Free do-follow backlink with content syndication.
Deployed Ahrefs Firehose — set up real-time web monitoring with rules for brand mentions, competitor tracking, and link building opportunities.

Total cost: $19 (ufind.best premium). Total backlinks gained: 4+.

2. Fixed 131 SEO issues

Dux ran through our Ahrefs Site Audit results and fixed:

35 page titles that were too long for search snippets
30 internal links pointing to redirects instead of final URLs
66 missing alt texts on images
11 hreflang tags connecting our Dutch and multilingual sites

Our health score? Heading from 71 toward 80+.

3. Set up competitor intelligence

Without being asked, Dux:

Created Firehose monitoring rules tracking 6 competitors (Shopnotch, By Association Only, Instijl Media, Opklopper, NewFive, Combidesk)
Set up keyword tracking for our target terms in Dutch
Built a daily routine to scroll X/Twitter feeds from 13 SEO and industry experts, flagging anything relevant

4. Rebranded our X presence

Our corporate X account wasn’t getting traction. Dux:

Changed the account from corporate branding to a personal brand (@duxleefromduxly)
Generated and uploaded a custom banner with code snippets and our tagline
Set the profile picture and bio
Published the first post (within character limits, with link preview)
Followed 13 key accounts in SEO, e-commerce, and AI

5. Managed the CMS

Throughout the day, Dux also:

Updated platform page ordering (41 items sorted by relevance)
Removed unauthorized client mentions from 4 platform pages (privacy compliance)
Re-added approved client references with internal links to case studies
Published multiple rounds of Webflow updates to both domains

What he didn’t do

Let’s be honest about the boundaries:

He didn’t write our strategy. The backlink targets came from tips our founder forwarded. The SEO priorities came from Ahrefs data. The agent executed, he didn’t strategize.
He needed help with payments. Stripe checkout required credit card details — a human had to provide those.
He couldn’t fix everything. Some Webflow issues require the visual Designer (not available via API). Those got logged as tickets for a human.
He asked before touching sensitive things. Config changes, external client communications, and LinkedIn posts all require human approval.

The numbers

Metric	Before	After
Domain Rating	31	34 (+3 in one month)
Live backlinks	91	534
Referring domains	29	30
Site health score	71	~80 (estimated)
X followers	0 engagement	Active presence
Competitor monitoring	Manual	Real-time automated

Why this matters

The “AI CMO” pitch from most startups is: enter your URL and magic happens. That’s not how marketing works.

What actually works is an AI agent with:

Real tool access — not simulated, actual API integrations
Domain knowledge — understanding your brand, competitors, and positioning
Human oversight — knowing when to act and when to ask
Persistent memory — learning from feedback and not repeating mistakes

This isn’t a product you buy off the shelf. It’s a custom agent built for your specific business, with your specific tools, executing your specific strategy.
