Who Should Your Documentation Actually Be Written For?

Who should your documentation actually be written for?

Two readers, in this order: the person evaluating whether to buy, and the person who already bought and is trying to finish a task. Most software companies write only for the second and then wonder why their documentation never appears in a sales conversation.

That is a marketing failure dressed up as a technical writing question. Docs are usually the most honest, most specific, most frequently updated pages a software company owns, and they are almost always owned by a team with no marketing remit and no traffic target.

There is also a third reader now, which is the reason this question got interesting again. Machines read your documentation, and several large companies have started building explicitly for that. Whether you should follow them is a more complicated question than the enthusiasm suggests.

Why are docs a marketing channel at all?

Because they answer the questions a buyer is too embarrassed to ask a salesperson. Whether the thing they need is actually supported. What the setup really involves. Whether the edge case they are worried about is handled or quietly ignored.

A marketing page cannot answer those honestly, because a marketing page is written to persuade. Documentation is written to be correct, and buyers know the difference. When I evaluate a tool for a client, I spend more time in the docs than on any other part of the site, and I am not unusual.

The specific moment docs decide a deal is the technical objection. Somebody on the buying side says this will not work with our setup. If your documentation shows that it does, in their vocabulary, that objection dies in ten seconds. If your docs are silent, the objection survives and a salesperson has to fight it on a call.

That is the whole business case. You are not trying to get documentation to rank for head terms. You are trying to make sure that when a sceptical evaluator goes looking for a reason to say no, they find an honest answer instead of a gap.

What are vendors building into their docs right now?

Machine-readable versions of the same pages, plus explicit invitations to AI tools. This is not speculation. It is printed on the pages themselves, and once you notice it you see it everywhere.

Webflow's developer documentation carries a banner on its pages telling you that appending .md to any page URL gives you clean Markdown, pointing to an llms.txt file as a complete documentation index, and inviting AI client integration by connecting to a documentation MCP server, naming Claude Code and Cursor as examples.

Stripe's changelog does something similar with different furniture. The page offers to let you ask about this page, copy for an LLM, and view as Markdown, alongside ordinary human filters for product and category, with categories including generally available and public preview, and named API versions running back through several releases.

Anthropic's platform release notes take a third approach, splitting by surface rather than by format. The page states that it lists changes to the API, the client SDKs, and the console, newest first, and points readers elsewhere for app release notes and to a repository changelog file for its command line tool. It offers a subscribe option and a copy page option.

Does machine-readable documentation help you rank?

Not according to Google, and it is worth reading that directly rather than through a consultant. Google's documentation on AI features says you do not need to create new machine readable files, AI text files, or markup to appear in those features, and adds that there is no special structured data you need to add.

It goes further. The same page says there are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimisations necessary, and that to be eligible as a supporting link a page must be indexed and eligible to appear in Google Search with a snippet, with no additional technical requirements.

I have written 350 articles about answer engines and schema, and this is the sentence I find myself quoting most often, because it contradicts a great deal of what is currently being sold. If somebody is telling you that publishing a particular file will get you cited by Google's AI features, Google's own documentation disagrees with them.

What Google does list among its fundamentals is making sure important content is available in textual form. That is a much weaker and much more useful instruction. It does not ask for a new file. It asks whether the substance of your page exists as text at all, which on a lot of documentation sites is a real question.

So why are companies shipping these formats anyway?

Because ranking is not the only reason to publish something, and treating it as one is how marketers end up confused by engineering decisions. A Markdown endpoint and a documentation index are distribution decisions, not ranking tactics.

Think about who actually consumes them. A developer pointing an AI coding tool at your documentation wants it to read the current version rather than a half-remembered one. Serving clean text and a complete index makes that more reliable. The payoff is a better experience for someone already building on you, which shows up as fewer support tickets and faster adoption rather than as traffic.

There is a second, quieter payoff. If your documentation is the easiest correct source about your product to retrieve, it is more likely to be the one that gets used when something summarises you. I want to be careful here, because I cannot verify how any given system weights those sources, and I have not seen a primary source that says it does. So I would treat this as a reasonable bet rather than a mechanism, and I would not build a business case on it.

My honest position is that these formats are cheap and defensible when your documentation is already good, and a distraction when it is not. Publishing a machine-readable index of pages that do not answer the question is just making a bad answer easier to fetch.

What changes if you write for the evaluator too?

You add context that operators do not need and buyers cannot proceed without. The operator already chose your tool. The evaluator is still deciding, and every page they land on is being read as evidence.

Three additions do most of the work. First, say what something is for at the top of the page, in one sentence, before you explain how to configure it. Second, state the limits plainly rather than by omission, because an evaluator reading a page with no limits assumes you are hiding them. Third, name the prerequisites, including anything that requires a particular plan, because discovering that on the page is neutral and discovering it after a purchase is not.

None of that damages the operator's experience, which is the objection I usually hear from documentation teams. A single orienting sentence costs a reader two seconds and saves an evaluator a support ticket. The two audiences conflict far less than people assume once you stop treating brevity as the only virtue.

What does not belong is persuasion. The moment documentation starts selling, it loses the credibility that made it valuable to a buyer in the first place, and you have converted your most trusted asset into another marketing page. I have written about the sibling version of this problem in writing an integrations page that ranks, where the temptation runs the other direction.

Where do documentation and marketing pages conflict?

On truth about limits, almost every time. Marketing wants to say it works with your stack. Documentation has to say which versions, under which conditions, with which caveats. When those two pages disagree, buyers find the disagreement and they do not assume it was an oversight.

My rule is that the documentation wins and the marketing page gets rewritten. That sounds obvious and it is organisationally hard, because the marketing page has a conversion target attached to it and the documentation page does not. Somebody has to decide that accuracy outranks the funnel, and it should be decided once, in advance, rather than argued each time.

The second conflict is vocabulary. Marketing invents a name for a feature, documentation uses the internal term, and neither matches what customers call it. That splits your own pages against each other in search and makes a buyer feel like they are reading about two products.

Fixing that is unglamorous and cheap. One canonical name per concept, written down, used in both places, with the customer's phrasing preferred over the internal one when they differ. It is the single highest-return editorial decision available to most software companies and it requires no new content at all.

How do you resource this without a documentation team?

Start with the pages that already get read and fix them, rather than commissioning a documentation project. Every product has a handful of pages carrying most of the traffic, and improving five of them beats writing forty new ones.

Get the list from your support queue rather than from analytics alone. The questions people ask repeatedly are the pages that are failing, and support tickets tell you what the reader expected to find. That is more actionable than a page view count, because it names the gap rather than just measuring the visit.

Then set a dated review rhythm and publish the dates. Changelogs from the companies I looked at all share one habit worth copying: entries carry explicit dates and live at stable, dated URLs. That is a small structural decision with two benefits, because a reader can tell whether a page is current, and so can anything else reading it. The same argument applies to what belongs in your release notes.

Finally, put someone's name on it. Documentation without an owner rots quietly, and rot in documentation is worse than absence because it actively misleads. One named owner and a quarterly pass is enough for most small companies, and it is more than most currently have.

What should you do next?

Open your three most-read documentation pages and read them as a buyer who has not decided yet. Look for one thing only: whether the page tells you what this is for and what it cannot do. If either is missing, that is your edit, and it is a paragraph rather than a project.

Then check whether your product's most important concepts are named the same way in your documentation and on your marketing pages. Where they differ, pick the customer's word and change both. If you want the layout side of this, I have covered documentation sidebar layout separately.

Leave the machine-readable formats until last. They are cheap and they are fine, and they will not rescue documentation that does not answer the question. Fix the answer first. If you want a second opinion on whether your docs are helping or quietly costing you deals, reach out.
