Structured Data Presentation

TL;DR

Your content is hard to extract and summarize because the structure is unclear. Add a concise top summary, fix heading hierarchy, and use structured formats like lists and tables for key information. Use Oversearch AI Page Optimizer to rescan and confirm extractability improves.

Why this matters

Clear structure improves extractability. LLMs and search systems prefer content that is easy to summarize, quote, and verify.

Where this shows up in Oversearch

In Oversearch, open AI Page Optimizer and run a scan for the affected page. Then open Benchmark Breakdown to see evidence, and use the View guide link to jump back here when needed.

Should I use tables for comparisons and specs?

Yes. Tables are the best format for multi-attribute comparisons and specifications because they are scannable, extractable, and display relationships between data points clearly.

AI systems and search engines can parse HTML tables and extract individual cells. A comparison table is more likely to be cited in AI answers than the same information in paragraph form.

• Use tables for: feature comparisons, pricing tiers, specifications, support matrices.
• Each row should represent one item, each column one attribute.
• Add a clear header row with descriptive column labels.
• Do not use tables for layout — only for tabular data.

If you use Oversearch, open AI Page Optimizer → Benchmark Breakdown to check format diversity.

When should I use tables vs lists?

Use tables when data has two or more dimensions (rows × columns). Use lists when data is one-dimensional (a sequence of items).

A feature comparison across multiple products is two-dimensional → table. A list of requirements for one product is one-dimensional → list.

• Table: comparing items across attributes (features, prices, ratings).
• List: enumerating items, steps, or requirements.
• If data naturally fits rows and columns, use a table.
• If items are just a sequence, use a list.

If you use Oversearch, open AI Page Optimizer → Benchmark Breakdown to see format recommendations.

Can tables hurt mobile usability?

Wide tables can cause horizontal scrolling on mobile, which hurts usability. Use responsive table techniques to prevent this.

Tables with many columns may not fit on small screens. The solution is not to avoid tables but to make them responsive.

• Wrap tables in a horizontally scrollable container.
• For simple tables: use a responsive CSS approach that stacks rows on mobile.
• For complex tables: consider a card-based layout on small screens.
• Test tables on mobile before publishing.

How do I make tables accessible?

Use proper HTML table markup with <thead>, <th> (with scope attributes), and <caption>.

Accessible tables allow screen readers to navigate cells and understand the relationship between headers and data. This also helps crawlers parse the table structure.

• Use <th scope="col"> for column headers and <th scope="row"> for row headers.
• Add a <caption> describing the table’s purpose.
• Do not use <table> for layout — only for tabular data.
• Ensure sufficient color contrast for text in table cells.

Common root causes

• Multiple H1s or inconsistent heading hierarchy.
• Long, unstructured paragraphs with no scannable sections.
• Key definitions missing or scattered.
• Visual/UI elements contain key info without textual explanation nearby.

How to detect

• In Oversearch AI Page Optimizer, open the scan for this URL and review the Benchmark Breakdown evidence.
• Verify the signal outside Oversearch with at least one method: fetch the HTML with curl -L, check response headers, or use a crawler/URL inspection.
• Confirm you’re testing the exact canonical URL (final URL after redirects), not a variant.

How to fix

Determine whether your data is best presented as a table (see: When should I use tables vs lists?) and ensure tables are accessible (see: How do I make tables accessible?). Then follow the steps below.

1. Place TL;DR immediately after the H1.
2. Use a single H1 and a clean H2/H3 hierarchy (one topic per section).
3. Convert long paragraphs into short blocks + lists + tables.
4. Add definitions for key terms near first mention.
5. Add relevant schema where appropriate (Article, FAQ only for real Q&A).
6. Run an Oversearch AI Page Optimizer scan to confirm structure/extractability improvements.

Verify the fix

• Run an Oversearch AI Page Optimizer scan for the same URL and confirm the benchmark is now passing.
• Confirm the page is 200 OK and the primary content is present in initial HTML.
• Validate with an external tool (crawler, URL inspection, Lighthouse) to avoid false positives.

Prevention

• Standardize templates so headings and TL;DR are consistent across pages.
• Use a content linter to prevent heading hierarchy regressions.
• Prefer scannable formats for key info (lists/tables).

FAQ

Should I use HTML tables or CSS grid for data?

Use HTML <table> for tabular data (comparisons, specs, schedules). Use CSS grid for layout. Crawlers and screen readers understand HTML tables semantically; CSS grids are invisible to them. When in doubt, if the data has rows and columns, use a real HTML table.

Do tables appear in featured snippets?

Yes. Google frequently pulls HTML tables into featured snippets for comparison and data queries. Use clear <th> headers and concise cell content for the best chance. When in doubt, add header rows with descriptive labels.

How do I make wide tables work on mobile?

Use responsive table patterns: horizontal scroll wrapper, stacked layout for narrow screens, or collapse less important columns. Never let tables break the page layout. When in doubt, wrap the table in a div with overflow-x: auto.

Should tables have caption and summary elements?

Yes. The <caption> element provides a visible title for the table. Use <th scope='col'> and <th scope='row'> for accessibility. When in doubt, add a <caption> describing what the table shows.

Can I replace tables with comparison lists?

For simple two-item comparisons, a side-by-side list can work. For three or more items across multiple dimensions, a table is clearer. When in doubt, use a table when comparing three or more attributes.

How can I verify table accessibility after changes?

Run Lighthouse accessibility audit and check for <th> headers, <caption>, and proper scope attributes. Test with a screen reader if possible. When in doubt, run an Oversearch AI Page Optimizer scan.
