Apply a default rule that substantive marketing content should include a relevant visual component unless there is a clear reason not to use one. Begin with the message and its source material, then choose the format that best helps the audience understand it: an infographic for compact synthesis, a slide deck for structured teaching, or another image-based asset for illustration and attention. Use source-grounded generation so the visual reinforces the same claims rather than becoming unrelated decoration. Tailor the output to the channel and audience, then review accuracy, rendering, hierarchy, and usefulness before publishing. The rule is enabled by the dramatic reduction in production time from tools such as NotebookLM and Nano Banana Pro, but it does not mean every first-generation image is acceptable. Multimedia becomes an operational default while relevance and quality remain release gates.

Core principles
- 01Pair substantive marketing messages with a relevant visual format
- 02Use source-grounded generation to keep visuals connected to the message
- 03Match the asset type to the communication job
- 04Do not let faster production remove human quality control
How to run it
- 1
Start with the message
Define the claim, lesson, or action the content needs to communicate before selecting a visual format.
Pro tip Write a one-sentence communication objective.
Watch out Starting with an image style can produce decorative content detached from the message.
- 2
Select the useful visual form
Choose an infographic, slide deck, illustration, or other format based on how the audience should consume the idea.
Pro tip Use infographics for compression and decks for progression or teaching.
Watch out Do not add visuals merely to satisfy the rule if they introduce no informational value.
- 3
Ground the visual
Generate from the same source corpus that supports the written content so the asset reflects the actual topic and evidence.
Pro tip Keep approved source material in a reusable notebook.
Watch out Ungrounded generation can create attractive but irrelevant or unsupported details.
- 4
Tailor it to the channel
Specify the intended platform, audience, dimensions, density, and brand direction.
Pro tip Optimize for the audience's viewing context rather than reusing one asset everywhere.
Watch out A presentation slide may be unreadable when posted unchanged to a social feed.
- 5
Apply the release gate
Verify the copy, imagery, source fidelity, legibility, and usefulness before publishing.
Pro tip Use the same short review checklist for every generated asset.
Watch out Faster production should not become permission to publish unchecked media.
In the wild
Instead of publishing a text-only summary of Gemini 3 marketing use cases, a marketer builds a notebook from relevant videos and articles and generates a branded LinkedIn infographic. The visual condenses the main use cases and gives readers a fast way to scan the argument while the accompanying post supplies context.
→ The marketing message becomes multimedia without requiring a separate multi-hour design workflow.
Common mistakes
Adding visuals without information value
A decorative image can increase production volume without improving comprehension, credibility, or attention.
Using the same asset everywhere
Different channels require different dimensions, density, pacing, and visual hierarchy.
Dropping human review
Low production cost does not eliminate rendering errors, weak framing, or synthetic-image fidelity problems.
Is it for you?
Best for
It is best for recurring social, educational, sales, and content-marketing workflows where visuals improve comprehension or attention.
Not ideal for
It is not ideal when a visual would be decorative, misleading, inaccessible, or disproportionate to the importance of the message.
From the transcript
“Like there's no reason now for any social post, any marketing content to not be multimedia now that we have Nano Banana.”
“It framed them really well.”
“this was very good and took a minute.”
