AEO Content Checker

This AEO content checker scores a draft or a live page against what Microsoft Bing and Google have published about content for AI search answers. It checks whether question headings open with a direct answer, whether each section makes sense on its own, and whether vague claims, overloaded sentences, hidden tabs, or snippet settings get in the way. Every issue is highlighted in your text with the fix, and you can add the questions people ask to see which ones your content answers. Paste from Google Docs or Word, drop in a .docx or Markdown file, or paste a page’s HTML.

How to use the AEO content checker

• Add your content. Paste a page’s HTML (press Ctrl + U on the page and copy everything), or copy from Google Docs, Word, or a web page and paste. Headings, lists, and tables are kept. You can also choose a .docx, .html, .md, or .txt file.
• Add questions (optional). Enter the main question the page should answer and other questions people ask, for example from Google’s People also ask box.
• Read the score and checks. Checks are grouped into answers, passages, clarity, access, and page signals. Open one to see why it matters, how to fix it, its source, and every place it applies.
• Fix it in context. Select Show in text to jump to the passage in the highlighted copy of your content.
• Share the results. Copy the report for a writer, or download the issues as CSV or the report as Markdown.

What Bing and Google say about content for AI answers

To optimize content for AI search, start with what the search engines have published. Google’s guide to AI features and your website says there are no additional requirements to appear in AI Overviews or AI Mode, and no special optimization is needed. The same SEO best practices apply: let Google crawl the page, keep important content in text, and make structured data match the visible text. It also says a page must be indexed and eligible to be shown with a snippet to appear as a supporting link.

Microsoft Bing has been more specific. Its October 2025 post on optimizing your content for inclusion in AI search answers recommends specific headings, direct questions with clear answers, concise answers of one to two sentences, self-contained sentences, lists and tables, and schema markup. It also lists mistakes to avoid, from walls of text and answers hidden in tabs to core facts only in PDFs and vague claims such as “next-gen”.

The AEO content checker turns that guidance into checks you can run on any draft. Each check links to its source. Thresholds, such as 35 words for a long sentence, are the tool’s own.

The 23 checks

Page-level checks, such as the robots meta tag and structured data, only run on a page’s full HTML. A draft from Google Docs or Word gets the content checks, so the AEO content checker can help before you publish.

Write direct answers under question headings

Bing says direct questions with clear answers mirror the way people search. The AEO content checker finds every heading phrased as a question or a how-to, then reads the first sentence under it. It flags answers that open with filler such as “Great question” or “In this section”, answers that start with “This” or “It” and only make sense with the heading above, answers over 40 words, and answers hidden in a collapsed accordion.

The second version names the subject, answers in the first sentence, and works on its own if an AI answer quotes only that sentence. The Sections & answers tab shows the opening of every section, so you can read each section on its own.

Make every section work as a passage

AI answers often use a single passage rather than a whole page. Bing recommends self-contained sentences that make sense even when pulled out of context, and strong headings that show where an idea starts and ends. The AEO content checker flags:

• Walls of text: paragraphs over 120 words, and sections over 350 words without a subheading, list, or table.
• Passages that need context: sections that open with a pronoun, and phrases such as “as mentioned above”.
• Vague headings: “Overview”, “Learn more”, “Why choose us”, and other headings that don’t say what the section answers.
• Lists and tables: long pages with neither, and pages where most of the text is bullet points, which Bing also warns against.

To check the heading outline in more detail, use the Heading Structure Checker.

Cut vague claims and overloaded sentences

Bing’s example of precise writing is “42 dB dishwasher designed for open-concept kitchens” instead of “quiet dishwasher”. The AEO checker underlines buzzwords such as innovative, revolutionary, seamless, and best-in-class when the sentence has no number to back them up. It highlights sentences over 35 words, counts sections with a number, measurement, or date, and marks em dashes and symbols such as arrows and “!!!”, which Bing lists as writing mistakes to avoid.

Check the questions people ask

Google says AI Overviews and AI Mode may use “query fan-out”, running several related searches across subtopics to build one response. A page that answers the follow-up questions directly gives those searches more to find. Add your questions, and the AEO content checker matches each one to the section that answers it by topic words in headings and opening sentences. Each question is marked answered, partly answered, or not answered, with the answer your page opens with.

Things that stop a page from appearing in AI answers

• Snippet controls. Google says nosnippet, data-nosnippet, max-snippet, and noindex limit what’s shown from a page in Search, including AI features. The AEO content checker reads the robots and googlebot meta tags and data-nosnippet sections.
• Hidden answers. Text in collapsed accordions, tab panels, or elements hidden with CSS is flagged, because Bing says AI systems may not render it.
• Text that isn’t in the HTML. If the page source has almost no text, the content may load with JavaScript. Paste the rendered HTML instead.
• Crawler access. Google’s first recommendation is allowing crawling in robots.txt. Test yours with the robots.txt Tester.

Answer engine optimization is good SEO

Answer engine optimization isn’t a separate set of tricks. Google says the same SEO best practices apply to its AI features, and its guidance on helpful, people-first content encourages accurate bylines where readers expect them, and warns against changing dates to make pages look fresh. That’s why the AEO content checker also looks at the byline, the date, and structured data, and why the score is a measure of how closely you follow the published guidance, not a promise of citations. To check your structured data in detail, use the JSON-LD Validator.
