A content agency sells people and strategy: editorial work, interviews, brand voice, often several channels. A blog system sells rhythm: topics from search data, one finished post per week, publishing and approval. The agency is the right fit when positioning, campaigns or content that needs a lot of explaining are the priority. The blog system is the right fit when the blog should run regularly at predictable cost.
Anyone searching for "content agency or software" usually already has a quote on the table or a pricing page open in the browser, and is wondering whether the cheaper option really delivers the same thing. The short answer: no, it delivers something different. This page puts the two offerings side by side so you don't end up comparing apples with monthly subscriptions.
What a content agency delivers
A content agency sells the working time of people who can write. This usually includes a strategy phase (target audiences, tone of voice, topic areas), an editorial plan, interviews with you or your staff, the writing itself, rounds of revisions, and often the handling of further channels such as website copy, brochures or campaigns. The agency thinks in terms of projects and monthly allowances, not posts per week.
The strength lies in breadth and in conversation: a good agency can turn a half-hour interview with the master carpenter into a post that no one else could write. The weakness lies in speed and cost per piece: every post needs a briefing, coordination and corrections, and that costs hours on both sides.
What a blog system delivers
A blog system is software with a fixed process: it tracks search queries from the industry and region, derives a topic plan from them, writes one or more finished posts per week complete with subheadings, FAQs and internal links, submits them for approval and publishes them directly on the website. It thinks in terms of rhythm, not projects.
The strength is reliability: the post arrives every week, whether you have time or not. The weakness is depth on topics that only emerge through conversation: a system doesn't know your customer story from last Tuesday unless you feed it in. More on the three ways to have a blog written can be found under Have a blog written.
Comparison across seven criteria
The price figures for agencies are rough ranges, as of October 2026, based on experience from quotes, not representative. Individual agencies may charge more or less.
| Criterion | Content agency | Blog system |
|---|---|---|
| Cost per post | CHF 400 to 1,200, depending on length and research | Included in the monthly price, usually works out to under CHF 50 |
| Cost per month | Retainer of CHF 1,500 to 5,000 for two to four posts plus consulting | Subscription between roughly CHF 130 and 400, depending on the number of posts |
| Lead time to the first post | Two to six weeks (strategy, briefing, draft, corrections) | A few days after setup |
| Depth of expertise | High for interviews and original research | Solid for guide-style topics, dependent on the information you provide for specialist knowledge |
| Control | Rounds of corrections, often two to three rounds | Approval with one click, or automatic publishing with the option to stop it |
| Contract commitment | Retainers often run six to twelve months, individual projects are flexible | Minimum term of a few months, then monthly after that |
| Breadth of service | Blog, website, social, print, campaigns | Blog, publishing, optionally shared on social media |
To put the "blog system" column in context: BlogPilot's plans range from CHF 199 to 399 per month (excl. VAT, as of October 2026), for one to seven posts per week; a startup plan with two posts per week costs CHF 129. The exact terms are on the pricing page.

When the agency is the better choice
There are situations where a blog system would be the wrong purchase, even if it's cheaper:
- The positioning isn't clear yet. If you don't know who you're writing for or what the company should stand for, you need a conversation first, not a weekly rhythm.
- The topics only emerge through interviews. An architecture firm that wants to tell the story of its projects, or a consultant whose method is the product, needs someone who listens and writes.
- Multiple channels and campaigns. When a blog, website relaunch, trade fair and LinkedIn campaign are planned together, an agency is the glue that holds it all together.
- Regulated statements. Financial, health or legal topics, where every wording needs to be checked, are better handled by an editorial team with specialist proofreading.
- Photos and video are part of it. A system delivers text; if you need visual content, you need people on site.
When the blog system fits
- The website is ready, the positioning is clear, only the blog stays empty.
- The topics are guide-style questions customers google: prices, process, comparison, regulations.
- The budget is under CHF 500 per month, but something should still appear every week.
- Approval should stay in-house, but shouldn't take more than 15 minutes per post.
- The blog is on WordPress, Wix or Shopify, or there isn't one yet.
A constructed example: an electrical business with eight employees had an agency for two years that delivered one post every two months. The posts were good, but too infrequent to move rankings. After switching to a weekly system, more posts went online in three months than in the two years before. Whether this applies to your business depends on whether rhythm or depth is your bottleneck.
The combination that often works best
The question "agency or software" has a third outcome: both, but with a clear division of tasks. The agency takes on positioning, the core pages of the website and two to four in-depth posts per year from interviews. The system handles the weekly guide-style content. Some agencies now offer this themselves and run the system for their clients.
If you're considering a single copywriter instead, you'll find the comparison under Blog system or freelance copywriter. The logic is similar, the numbers are smaller.
The questions you should ask both
Whichever side you're leaning towards, these five questions will clarify the rest: Who owns the texts? What happens to ongoing posts if you cancel? Who checks facts before publication? What does a post actually look like before I sign? And how many hours does this cost me per month, not just in Swiss francs?
Frequently asked questions
Can an agency run a blog system for the customer?
Yes, this happens. The agency handles strategy, approval and quality assurance, while the system delivers the posts on schedule. The SME keeps a single point of contact, and the agency can focus its hours on what people do better.
Are texts from an agency better for Google than texts from a system?
Google states that it doesn't assess how a text was created, but whether it's helpful. An agency text with an interview and first-hand experience can be more in-depth; a system text is usually more punctual and cleanly structured. What matters is that someone with expertise checks the post before publication, regardless of where it comes from.
What contract terms are typical with agencies?
Retainer contracts often run for six or twelve months, while individual orders per post can be arranged without commitment. Ask about the notice period and what happens to posts already in progress if you cancel. With blog systems, minimum terms of a few months are common.
What happens to the posts if I switch providers?
With an agency, the texts normally belong to you once paid for, check this in the contract. With a blog system, the posts live in your CMS if the system publishes via WordPress, Wix or Shopify; with a hosted blog, the export should be clarified before signing the contract.
