To automate your company blog with an AI agent, give it three things: a fixed source of truth for every factual claim, a written process it must follow for each article, and a set of guardrails it is not allowed to break. The agent then picks a topic, checks it has not been covered, drafts to that process, and publishes. What it cannot be given is judgement about your business. That stays with you, and the guardrails are how you enforce it.
We run this on our own blog, so the rest of this article is what we learned building it rather than a theory.
What can an AI agent actually do for a company blog?
More than most people expect on the mechanics, and less than most people hope on the strategy. If the word “agent” is still fuzzy, what AI agents actually do covers the distinction between an assistant that answers and an agent that acts.
The parts it handles well
Choosing the next topic from a maintained backlog, checking that no existing article already targets the same keyword, drafting to a defined structure, writing the meta description and title to length, adding internal links, and publishing through the CMS API. These are rule-following tasks with a clear definition of done, which is exactly where agents are reliable.
The parts it handles badly on its own
Deciding what your company should be known for. Judging whether a claim is safe to make. Knowing which customer story you have permission to tell. An agent asked to write persuasively will reach for numbers and examples, and if you have not told it which ones are real, it will produce plausible ones. That is the single biggest risk in the whole setup.
What should stay human?
Three decisions, in our experience.
Positioning. What the blog is arguing for, over months, is a business decision. Give the agent the conclusion, not the question.
Facts. Every number, customer name, result, and product capability should come from a file a human maintains. We keep one page per product listing what may and may not be said, including an explicit list of claims that are false. Our expense app Receiply organises receipts, for example, and that page states plainly that it does not file taxes or calculate VAT. The agent cannot drift past what is written there, because anything not on the page is not available to it.
Anything legally loaded. Testimonials, comparative claims about competitors, regulated advice. Keep these off the automated path entirely.
What guardrails does an unattended publisher need?
If nothing is reviewed before it goes live, the guardrails are the only safety net. Ours are short enough to be checked every time:
- No invented evidence. No testimonials, customers, or metrics unless supplied by a person.
- One keyword, one article. The agent checks published posts first and updates the existing article instead of writing a competing one.
- A uniqueness window. No repeat of a topic, core claim, or opening line within a set period, so the blog does not quietly loop.
- Product claims from the source file only. Precision matters more than enthusiasm here.
- A named process it must complete. Structure, internal links, meta description, FAQ block. A checklist the agent has to pass before publishing.
Write these down as a file the agent reads on every run, not as instructions in a chat. A guardrail that lives in someone’s memory is not a guardrail.
How do you set it up?
- Write the source of truth first. One page per product or service, listing verified facts and forbidden claims. This takes an afternoon and prevents most failures.
- Write the process document. Article length, structure, how keywords are chosen, what must be true before publishing.
- Build the topic backlog. Real questions your buyers ask, not category labels.
- Connect the CMS. Most content platforms expose an API. The agent drafts and publishes through it.
- Schedule it and log everything. Every published piece recorded with its keyword and result, so you can tell what is working.
- Read the first ten yourself. Not to approve them, but to find the gaps in your own instructions.
This pattern is not specific to blogging. It is the same shape as any workflow automation: a defined process, a constrained source of truth, and an agent that executes it consistently. Invoice processing is the same architecture pointed at a different document, and seven admin tasks you can automate today lists the other places it fits.
Is it worth automating?
It is worth it when the bottleneck is consistency rather than ideas. Most company blogs do not fail because nobody had anything to say. They fail because publishing slipped for three weeks, then three months. An agent does not lose interest in week four.
It is not worth it if you have no clear positioning yet, because you will automate the production of vague content. Fix that first.
Frequently asked questions
Will Google penalise AI-written content?
Google’s guidance targets content produced primarily to manipulate rankings, not the tool used to write it. Helpful, accurate, original content is judged on those qualities. Thin, repetitive articles are the risk, whoever writes them.
Should the agent publish without approval?
Only if your guardrails are genuinely strong and your source-of-truth files are complete. Start with review, remove it once you have seen the agent handle the awkward cases correctly.
What does it cost to run?
The recurring cost is model usage, which for a twice-weekly blog is small. The real cost is the setup: writing the process and fact files properly. That is a day or two of a person’s attention, and skipping it is what makes these projects fail.
Can the same agent handle social posts?
Yes, and it is more efficient to write one topic once and adapt it per platform than to run separate content processes. The constraint is that each platform has its own limits and tone, which belong in the process document.
Should we buy a tool for this or build one?
Buy first if a generic tool covers it. Build when the process is specific to how you operate, which is usually the case once your source-of-truth files are involved. Off-the-shelf AI versus custom AI works through where that line sits.
Where to start
Begin with the source-of-truth file. Everything else in this setup depends on it, and it is useful even if you never automate anything.
