Seven Mistakes People Make Writing Content for AI

Most businesses still write with traditional habits when they produce content for AI search engines like ChatGPT, Gemini and Google AI Overview, and that is one of the most common reasons a brand never appears in AI answers. A text that reads smoothly and persuasively for a human reader is judged differently by AI models. These models look for clear answers, structured information and verifiable sources; ornamental opening sentences and indirect narration are an obstacle to them.

Content teams usually do not notice these mistakes, because the text looks entirely normal when a human reads it. The problem is not in how the page looks; it is in how an AI model parses that page and which signals it hunts for. In this article we go through the seven content optimization for AI mistakes we run into most often in the field, and the workable fix for each one.

1. Not Using a Question Format in Headings

AI models tend to prioritize headings that map directly onto the questions users ask in natural language. A generic heading such as "Appointment Reminder Systems" is less quotable than a question-shaped one such as "How Do You Set Up an Appointment Reminder System?". The reason is that the model looks for a direct match between the user's query and the page heading, and a question format makes that match easy.

The fix: Frame every main heading as a real question your audience could put to a search engine or to an AI assistant. Writing at least some of the subheadings with the same logic strengthens the answer-like quality of the content. You do not have to turn every heading into a question; what matters is using the format on the topics that draw the most searches. The same approach applies to city-based service pages.

How to spot it: Pull every heading on the page into a single list, then write next to it the questions your customer representatives are actually asked. If the two lists overlap nowhere, the headings were written as topic labels. Queries arriving at the page in Search Console that are phrased as questions and never appear in any heading are the same symptom.

2. Not Giving a Clear Answer in the First 50 Words

When an AI model scans a page, it does not read to the end to find the answer to the topic. If the opening paragraph is given over to indirect narration, storytelling or generic sentences, the model treats that content as "vague" and turns to another source. This costs visibility above all on informational queries of the "what is" and "how to" kind.

The fix: Give the clear definition of the topic, or the direct answer, in the first few sentences of the first paragraph. Elaboration, examples and nuance come after that clear answer, not before it. Once you have written the opening paragraph, ask yourself the question: "Would someone reading only this paragraph get the answer they came for?"

How to spot it: Copy the first paragraph out of the text, read it to someone who cannot see the heading, and ask what it is about. If they cannot say, the paragraph is not an introduction but a warm-up. Another practical sign is the topic name never appearing in the first paragraph, or the paragraph opening with formulas such as "these days" and "in recent years".

3. Leaving Out Structured Data (Schema)

Even when a page looks visually tidy, AI models and search engines also want to see the information in a machine-readable structure. On a page with no schema markup, things such as the answer to a question, the identity of the author or the publication date are not conveyed clearly to the model; even when that information sits on the page, it may not be parsed reliably by a machine.

The fix: Add FAQ, Article and Organization schemas to your page in particular. This makes your content readable by AI not only visually but technically. Treat adding schema not as a one-off technical job but as a standard step repeated at every new content publication.

How to spot it: Search the page source for the string application/ld+json; if it never appears, there is no structured data. If it appears but the schema validator throws errors, the situation is more insidious: the markup exists and is not being read. Another common case is the schema not matching the real content on the page, such as an FAQ question sitting in the schema that is nowhere in the text.

4. Making Unsourced or Vague Claims

Claims with an unclear source that cannot be verified, of the "most businesses achieve great success with this method" kind, reduce both user trust and the likelihood of AI models citing your content as a reliable source. Vague claims form a weak signal in E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) terms and can push the model to classify the content as marketing talk.

The fix: Rather than inventing precise but unverifiable figures, use cautious and realistic wording: "usually", "frequently", "in the 20-30% range". Include the general industry knowledge or the logical reasoning that supports your claim; adding an invented number to make a claim concrete may look convincing in the short term, but it damages credibility over the long run.

How to spot it: Mark every number, every percentage and every superlative in the text, the "the most", "leading" and "many times over" kind included. Then try to write the source next to each mark; every item you cannot source has to be sourced, hedged or removed. This sweep pays off most on older content, because invented numbers are usually added to a text later on, to make it more convincing.

5. Writing the Content as One Long Paragraph

Long, undivided paragraphs are a hard structure to process for human readers and AI models alike. The model struggles to tell several different topics apart inside a single paragraph, and that lowers the chance of the content being quoted as the answer to a specific question. Long paragraphs also make the page less scannable, which drags the user experience down with it.

The fix: Give each subheading a single clear topic, keep paragraphs short and use bulleted lists where they help. If there is more than one main idea under a subheading, consider splitting that heading in two. As a general rule, finishing a single thought in a paragraph and then moving on raises both readability and quotability.

How to spot it: Try summarizing each paragraph in one sentence. Every paragraph where you need the word "and" to summarize it holds at least two topics. Paragraphs running past a hundred words, and paragraphs carrying three or four subordinate clauses strung together with semicolons, are the same problem made visible.

6. Leaving Outdated Information Unrevised

AI models tend to avoid using pages that carry out-of-date information as references. An old publication date, or a paragraph describing a practice that no longer applies, can damage the credibility of the entire page; once the model sees outdated information in one section, it may approach the whole page with suspicion.

The fix: Review your content at regular intervals, update the sections that have gone stale and, where possible, show a "last updated" date on the page. This signals to the user and to the model alike that the content is current. On topics that change often, such as regulation, pricing and technology tools, it helps to put that review on a calendar. We take this regular maintenance on as part of our GEO service packages as well.

How to spot it: Sort your content list by last-updated date and, starting from the oldest, look at three things: phrases that point back at last year ("this year", "soon", "not yet"), the names of tools and products whose name or interface has changed, and broken external links. If one of those three signs is present, the whole page needs a review.

7. Not Stating Brand and Author Identity

If it is unclear who wrote the content and with what expertise, AI models hesitate to prioritize that content as a reliable source. Anonymous or unattributed content is one of the cases where E-E-A-T signals are at their weakest, and it comes off worse when set against competing content.

The fix: State the author or the organization clearly in every article and, where possible, add a short note on their expertise. Showing your corporate identity consistently sends a trust signal to the user and to the AI alike; that consistency also covers the brand name appearing in the same form across different pages and platforms.

How to spot it: The author's name appearing on the page is not a sufficient signal on its own. There are three points to check: does the name also appear in the author field of the structured data, is there a page on the site behind that name or at least a note on their expertise, and does the same name appear with the same spelling on profiles off the site. If all three are missing, the name stays an unverifiable label.

Which Mistake Should You Start With?

The seven items do not have to be closed inside the same week; the order follows effort set against expected impact.

This order is a suggestion about how to divide up limited time, not a rule. The one case that breaks the order is a site with no structured data at all; if schema can be added to every page in one pass at template level, it makes sense to pull it forward while the technical team is free. The priority order can come out differently on a corporate site: on the GEO for enterprise B2B brands side, author identity and source attribution usually weigh more heavily.

How Do You Check Whether the Fixes Worked?

The first step of the check is to look at the page not through your own eyes but in the form a system that reads text sees it. With JavaScript switched off, or when only the text output of the page is taken, how much of the content stays in place? If the main text, the headings and the contact details are missing from that view, then none of the content fixes you made are reaching those systems. We covered the server-side counterpart of access in the are AI bots reaching your site article.

The second step is getting the structured data through a validator. What is being looked for here is not merely the absence of errors; it is the fields in the schema matching the real content on the page one to one. Keeping an FAQ question in the schema that is not on the page is not a fix, it produces a fresh inconsistency.

The third step is querying the engines regularly with a fixed question set. Because the answer and the sources shown can change when the same question is asked twice, a single observation is not enough to decide on; what counts is repeating the same questions in the same form and recording how many answers the brand appears in. The measurement window has to be set realistically as well: a change made on a page can take weeks rather than days to be re-crawled and reflected in answers, so a result checked one day after the fix tells you nothing. We gathered which metrics are worth tracking under five headings in the how to measure AI visibility article. We treated the difference between writing content for AI and producing content with AI, and the limits on the production side, as a separate topic in the article on AI social media content: brand voice and limits.

Frequently Asked Questions

Do all of these mistakes have to be fixed at the same time?

No, moving in stages is possible. Starting with low-cost fixes such as giving a clear answer in the first 50 words and reworking the heading format, then applying technical steps such as schema and content structure in a later phase, lets you follow a sustainable path.

Does fixing these mistakes hurt traditional SEO?

Usually the opposite happens. Clear answers, structured data and current content produce positive signals at the same time for traditional search engines and for AI-based search experiences alike.

Do these seven mistakes carry the same weight in every sector?

No, the weight shifts with how sensitive the subject is. In fields where the consequence of a decision is heavy, such as health, law and finance, author identity and the sourcing of claims come to the front; on technical and educational topics where informational queries dominate, the clear answer and the heading format are more decisive. In local service businesses the most frequently encountered gap is structured data, because information such as the address, the opening hours and the service list may not be defined on the machine side even when it is written out on the page.

Does having AI write the content solve these mistakes?

It does not solve them by itself; it makes some of them easier and deepens others. Text produced with a language model usually has an orderly heading structure and short paragraphs, which means it falls into the fifth mistake less often. Against that, the risk of producing unsourced claims and unverifiable figures rises, because the model can build a convincing-looking sentence even with no source behind it. Author identity and the conveying of real experience are, by definition, not delegable.

How long does it take to see the result of the fixes?

Giving an exact duration is not possible, because the chain runs through several steps: the page being re-crawled, the crawled content being processed into the indexes those systems use, and the source selection in answer generation changing. Since each of these steps moves at a different speed, the observation window has to be set in weeks rather than in days. The one place faster feedback can be had is the technical checks: structured data passing the validator, and the page being complete in its text view, can both be verified the same day.
