We’re going to break down what to include in your articles, to optimise for AI, for search engines and for your users.
Is there anything worse than clicking through to a page to be greeted with big blocks of text and nothing else? We don’t know if it’s just us, but we’d rather dive into a hawthorn bush than read a load of website copy with no structure.
Does the structure of content help with SEO and AI optimisation?
Yes – it does and we’re going to share that work. While everything to do with SEO and AI seems to have been moving forwards at turbo-speed recently, making it nigh on impossible to be able to prove what’s definitely working and what isn’t, formatting is the exception. Formatting has always been important and it remains crucial for keeping the attention of your users and for capturing the attention of search engines and LLMs (Large Language Models – AI platforms).
We’ve seen first-hand how having effective formatting helps articles to show up in AI overviews, in answers on ChatGPT and Gemini and to rank traditionally in Google searches, too.
Why is the formatting of articles so important for optimisation?
· For users:
-
- Users want to find the answer to their question and to be led on to read anything else that adds additional value
- To be able to quickly scan to find the right section or get a rough overview of what a website page is about
· For search engines:
-
- Search engines like Google need to understand what your content is about and which parts matter most, so semantic HTML signals (just like the ones mentioned below for AI) help it to understand what content is on the page, how important it is and what is most relevant to the search query it’s answering
· For LLMs:
-
- AI values hierarchy, so headings, paragraphs and lists help AI to see what is most important, in a logical order
- Semantic HTML signals (headings, lists, tables) help AI to understand what type of information it’s processing
- AI breaks content into chunks to process its meaning, so using a clear structure helps it to find natural breakpoints for its chunks, instead of it having to sift through any information that isn’t as relevant
- Having designated sections for clear information reduces ambiguity for AI – even if you still include qualitative information, first-hand opinions and whimsy – as long as you have all the facts clearly set out, it’ll be able to easily extract the information it needs without misinterpreting it
Overall, what’s important is to cut out the guesswork for everyone. The clearer your content is, the easier it is to digest and be stored – by everyone.
Techniques for optimal AI & SEO formatting
| Optimisation technique | What it is | Example | Why it’s important for AI & SEO | Top tips |
| BLUF (Bottom Line Up Front) | Putting the most important message at the very top of the page | Making it clear what the page is about without fluff: “Magnesium can support sleep by calming the nervous system and improving sleep quality” | AI and search engines place a higher priority on the content at the top of a page | Avoid using long intros and instead make a statement that gets to the point quickly |
| One clear topic per article (focused intent) | Structuring each article around one topic instead of having super-long articles that cover more in less detail | One article on “Does magnesium help sleep?” instead of adding sections for mattresses, blue light and exercise | Articles with a clear focus make it easier to classify what the article is about | Use internal links to connect related articles into a topic cluster |
| Clear H1 | One main heading that defines the page’s purpose | “Does Magnesium Help You Sleep?” | Helps search engines and LLMs instantly identify topic and intent | Only one H1 per page |
| Logical H2 and H3 hierarchy | Breaking content into clearly structured sections | H2: “Benefits of Magnesium for Sleep”
H3: “Stress reduction” |
AI follows semantic structure top-down when parsing content | Always make the most of headings – go back through to re-optimise old articles if you’re not already |
| Descriptive headings (not vague) | Headings that explain the section’s takeaway | “How Magnesium Supports Deeper Sleep” instead of “Benefits” | Improves passage-level understanding and featured snippet eligibility | Headings should work as standalone summaries |
| Short paragraphs | Keeping paragraphs concise and readable | 2–3 sentence blocks explaining sleep stages | Easier for AI chunking and user scanning | Aim for one idea per paragraph |
| Bullet point lists | Breaking information into scannable points | List of foods high in magnesium for sleep | AI extracts list data easily for summaries | Use when listing benefits, steps or examples |
| Numbered lists | Ordered steps or processes | “5 Steps to Improve Sleep Quality” | Provides sequence and structure to AI models | Ideal for how-to content |
| Tables | Structured comparison or data presentation | Table comparing magnesium vs melatonin | Machine-readable and AI-friendly | Keep headers clear and consistent |
| Consistent terminology in headings and paragraphs | Using the same terms throughout | Always using “sleep quality” instead of switching phrasing | Reduces ambiguity for AI understanding | Avoid unnecessary synonyms |
| FAQ sections | Explicit Q&A blocks | “Does magnesium make you sleepy?” | Improves eligibility for AI overviews and voice search | Use real search-style questions |
| Answer-first formatting | Giving the answer before the explanation | “Yes – magnesium can help sleep” followed by why | Matches how AI generates direct answers | Especially effective for FAQs |
| Internal linking | Linking related articles together | Linking magnesium article to “Best supplements for sleep” | Helps AI map topical authority | Anchor text should be descriptive |
| External authoritative citations | Referencing trusted sources | Citing sleep studies or NHS guidance | Builds trust signals for AI and search engines | Place links near relevant claims |
| Semantic HTML | Using proper HTML tags (headings, lists, tables) | Correctly marked-up FAQ section | AI uses HTML structure to understand relationships | Avoid styling text instead of tagging it |
| Clear section intros | Briefly explaining what each section covers | “This section explains how magnesium affects the nervous system” | Improves contextual parsing | 1 sentence is enough |
| Multimedia (videos) | Embedding relevant videos | Short explainer video on bedtime routines | Enhances engagement and understanding | Always add descriptive captions |
| Image captions & alt text | Explaining visuals clearly | Alt text describing a sleep posture diagram | Helps AI interpret non-text content | Avoid keyword stuffing |
| Consistent formatting patterns | Repeating layout structures across pages | Same FAQ layout across all sleep articles | Makes content easier for AI to predict and parse | Improves site-wide coherence |
| Defined entities | Clearly explaining key concepts | Defining “circadian rhythm” early | Helps AI build knowledge graphs | First mention should include definition |
| Avoiding content bloat | Removing unnecessary filler | Cutting long lifestyle anecdotes | AI prioritises signal over noise | Less is often more |
| Conclusion with reinforcement | Summarising key points at the end | Recap of how magnesium supports better sleep | Helps AI reinforce main takeaways | Avoid introducing new ideas here |
| Consistent page templates | Using similar layouts across articles | Same structure for all supplement guides | Helps AI learn site patterns | Especially useful for large sites |
| Clear intent alignment | Matching content to search intent | Informational article, not sales-led | AI ranks pages that satisfy intent best | Don’t mix informational and transactional aims |
