Marketing Case Study Design Tips for Evidence and Access
Marketing case study design tips keep evidence, context, access, rights, and testing clear across web, mobile, PDF, print, email, and social formats.
What to take away
- Design from the approved claim ledger so the result, comparator, period, population, source, attribution, disclosure, and limitation remain visually connected.
- Provide chart values and meaning in text, use readable labels and contrast, avoid distorted scales, and preserve a logical order when images or styles are unavailable.
- Test web, mobile, PDF, print, presentation, email, and social derivatives separately because every export or crop can change meaning, rights, and accessibility.
Marketing case study design tips should make evidence easier to inspect. Do not use scale, color, cropping, or typography to make a modest result appear larger or to hide a material disclosure.
Build a scanning layer and a deep layer
A scanning layer can show customer, situation, intervention, verified headline result, period, and relationship disclosure. A deeper layer should include baseline, implementation, formulas, sources, attribution, alternative explanations, quote context, and lessons. Use informative titles, semantic headings, descriptive links, and a logical order rather than relying on visual styling alone.
Use this narrative sequence as a reusable case study outline: customer and challenge; intervention; verified result with comparator and period; implementation details; lessons; next step. Put each customer quote beside the speaker's name and role, approval status, and enough context to preserve its meaning. Place a relevant call to action after the evidence, and use social proof only when its basis and permissions are clear.
Two Reading Layers
Scanning layer
- Content
- Customer, situation, result
- Disclosure
- Relationship disclosure
- Result
- Verified headline result
- Period
- Period shown
- Structure
- Informative titles, headings
Deep layer
- Content
- Baseline, formulas, sources
- Disclosure
- Alternative explanations
- Result
- Quote context, lessons
- Period
- Implementation detail
- Structure
- Logical order, links
Lay out the cover before and after
Before
- Headline
- 'Record growth'
- Qualifier line
- absent
- Main visual
- cropped chart without axis
- Footer
- logo only
After
- Headline
- '[Metric] moved from [baseline] to [result] in [period]'
- Qualifier line
- 'Population: [group]; source: [source]; disclosure: [status]'
- Main visual
- chart with labeled axis, unit, period, and key values in caption
- Footer
- 'Limitation: [what the result does not show]'
The after column keeps claim, qualifier, and limit in one reading path. Redraw the wireframe with your own approved claim ledger fields before you build the page.
An approved claim ledger is a working record for each proposed claim: exact wording, result, comparator, period, population, source, attribution, disclosure, limitation, and approval status. Use it to decide which claims appear in headlines, charts, captions, and derivative assets.
Keep the result attached to context
Place metric name, magnitude, comparator, period, population, and source together. Do not put a large percentage on the cover while moving its denominator or limitation to an appendix, and show counts beside rates when they prevent distortion.
Label platform-attributed, modeled, estimated, and independently reconciled figures so readers do not assume they are equivalent. Those pairs are what the marketing case study sections exist to keep together.
Design honest charts
The W3C's WCAG 2.2 (2023) non-text contrast guidance explains that graphical objects needed to understand content generally require 3:1 contrast against adjacent colors at Level AA and notes that text within graphics has separate contrast duties. It also recognizes equivalent information in another form, such as a data table or long description.
Label axes, units, periods, populations, scales, and data sources. Use direct labels and restrained color. Avoid unexplained truncated axes, three-dimensional effects, area graphics that distort magnitude, or decorative precision. Provide the chart's meaning and key values in nearby text and a fuller equivalent when a short alternative cannot carry the information.
Set type, spacing, and mobile layout
Use a typical body size that remains readable, with comfortable line height and line length. Keep section spacing consistent. Use a consistent type system, left align long text, and avoid all caps for paragraphs.
On mobile, use one column, fluid images, and generous side margins. WCAG 2.2 Level AA's Target Size (Minimum) criterion sets a 24 by 24 CSS-pixel target, subject to exceptions. Follow WCAG 2.2 Level AA contrast requirements: 4.5:1 for body text and 3:1 for large text. Do not bake text into images.
Protect rights and people
Use approved photographs, logos, screenshots, quotes, and personal details. Record creator, owner, license, permitted edits, territories, channels, credit, expiry, and withdrawal. File access, customer approval, or a person's presence in an image does not by itself settle copyright, privacy, publicity, confidentiality, or trademark questions.
Test every output
Section508.gov's electronic-document testing overview identifies PDFs, editable documents, spreadsheets, and presentations as electronic documents and tells U.S. federal authors to build accessibility in and test conformance. Keep that federal scope: the page is a testing prompt, not certification for one export.
A marketing case study checklist records which tests passed. Run one ordered test list:
- Test web and mobile reading order, headings, keyboard access, zoom, and contrast.
- Test the PDF and print exports for tags, table labels, captions, text extraction, and copy and paste.
- Test presentation, email, and social crops separately; confirm each crop cannot detach the result from period, source, disclosure, or limitation.
- Test screen-reading technology and meaningful links, and preserve a text-first version when visual exports cannot carry full context.
Case-study design stress test
| Design area | Failure condition | Pass evidence |
|---|---|---|
| Claim context | Cover metric detached from limits | Result and qualifiers remain together |
| Chart | Color loss, zoom, image unavailable | Values, labels, and text equivalent |
| Rights | Crop, translation, expired permission | Use stays within recorded scope |
| Export | Order, tags, links, text extraction | Delivered format passes manual tests |
Design the comparison before you design the page
The GAO evaluation design guide connects evaluation questions with evidence needs and design choices. Design the comparison before you design the page: choose the question, comparison, period, population, and source first. Federal evaluation guidance does not make a local result causal or transferable. The marketing case study examples show how the question changes the design.
The NIST experimental design selection guidance begins design choice with the objective and practical constraints. It supports separating design reporting from controlled effect estimates, not turning observation into causation.
Common questions
Should the biggest number dominate the cover?
Only if its comparator, period, population, source, attribution, disclosure, and limitation remain clear enough to prevent a broader impression than the evidence supports.
Is alt text enough for a complex chart?
Often not. Provide a concise alternative plus the key values, trend, comparison, and limitation in nearby text or another accessible equivalent.
Can one approved design be cropped for every channel?
No. Review each crop and derivative because it can remove context, disclosure, permission, identity, chart labels, accessible text, or the route to the full evidence.
