Publish a clear HTML explanation alongside a research PDF when readers need to understand and verify its findings on the web. Keep the two versions aligned and test what can actually be extracted from the PDF.
Separate format support from useful evidence
Google lists PDF among its indexable file types. That establishes format support in Google Search, not guaranteed indexing or citation by any AI provider.
A PDF can still be difficult to use if its central claim appears only in an image, its tables lack explanatory context or the methodology is missing. Review it as evidence rather than assuming that a downloadable file is self-explanatory.
Give the HTML companion a job
Include the research question, population, collection period, method, limitations and a concise explanation of the result. Link to the full PDF and identify its version and publication date.
Do not create an HTML page that merely says “download the report.” A visitor should understand what the document contains and whether it answers their question before opening it.
Illustrative example: a survey PDF reports responses from a specific industry. The companion page should name that industry and sample definition, preventing a reader from mistaking the result for an economy-wide benchmark.
Test the evidence path
- Open the PDF anonymously and confirm a successful download.
- Extract or select the text of the main claim and a representative table.
- Check that labels, units and footnotes remain understandable.
- Verify that the method and source notes are present.
- Compare key facts against the HTML companion.
- Test links from both formats to supporting public material.
If extraction is poor, improve the source document or provide an accessible text equivalent. Do not infer that every AI system will use the same extraction method as your test.
Maintain one research edition
Assign an edition identifier and a correction owner. When correcting a figure, update both formats, preserve a correction note and avoid silently replacing a file while leaving an obsolete summary online.
Keep private customer observations and restricted datasets out of the public PDF unless publication has been explicitly authorized. A methodology page can explain how evidence would be collected without publishing unapproved results.
Use the content optimization guide for evidence-first writing. Next, review technical accessibility with AI Readiness and manually test the HTML-to-PDF evidence path before promoting the research.
