Image Assets vs Structured Snippets

In short: Both attach supplementary content beneath a search ad, but one is a picture and the other is a line of text under a fixed header. Image assets show a photograph, mainly on mobile placements, and are governed by visual-content policy like overlay text and collage rules. Structured snippets show a header you pick from Google's fixed list - Brands, Types, Services - followed by values you type, signaling breadth of coverage rather than a benefit. They solve different trust problems: one shows what the product looks like, the other shows how much you carry. Reach for an image when a photo builds confidence faster than words, and a structured snippet when you need to prove range.

Image Assets

Adds a square or landscape image to a text search ad, shown mainly on mobile results alongside the headlines and description.

Previously image extensions, these attach visual inventory to an otherwise text-only search ad, and Google serves them when it predicts a lift. Images must meet size rules and cannot be collages or carry heavy text overlays and corner logos. The mistake is uploading marketing banners, because text-laden creative gets rejected in review, while a plain product or service photograph passes and renders cleanly beside the ad.

Structured Snippets

A predefined header such as Services or Brands followed by a list of values, rendered as one line beneath a search ad.

You pick from Google's fixed header categories and then supply the list items, since the header itself cannot be custom. Formerly structured snippet extensions, they signal coverage, meaning which models, courses, or destinations you handle, rather than promoting a benefit. The mistake is confusing them with callouts: a list of unrelated marketing phrases under a category header reads as noise and can be disapproved.

Side by side.

The differences that actually change what happens in your account.

	Image Assets	Structured Snippets
What you supply	Image files sized to Google's ratio rules.	Values under a header you pick from Google's fixed list.
Can the header or format be customized	N/A - it's a picture, not a header-and-list structure.	No, the header itself is fixed; only the list values are yours.
Content policy risk	Text overlay, collages, and corner logos can get it rejected in review.	Vague marketing phrases in place of real coverage items can get it disapproved.
Auto-fill behavior	Google can auto-select images from your site or feed if you leave it empty, with an opt-out available.	You supply every value yourself for the asset - there's no per-field auto-suggestion the way images get automatically selected from your site.
Where it typically renders	Mainly mobile search results, and only when Google predicts a lift.	Renders as one text line under the description, more consistently across devices.
What it communicates	What the product or service actually looks like.	Which models, services, or destinations you handle.
Minimum content required	At least one compliant image.	At least three list values under the chosen header.

What actually separates them.

Image assets are visual and governed by image-specific policy - no heavy text overlay, no collage, no corner logo - while structured snippets are plain text with no image policy involved at all.

Structured snippets require picking from Google's fixed header list and then supplying at least three values; image assets have no header or list structure, just a file.

Google can auto-select an image from your site or existing feed if the field is left empty; a structured snippet field left empty simply doesn't serve, since there's no per-field auto-suggestion for it the way there is for images.

Image serving depends on Google predicting a lift and having placement space, so it doesn't always show even when approved; structured snippets are text and render far more consistently once approved.

Structured snippets prove breadth of coverage - what you handle - while image assets prove appearance - what it looks like; they answer different questions in the click decision rather than competing for the same one.

Which one should you use?

Use Image Assets when

You sell a physical product or visible service where a photo builds trust faster than more text.
You have real, policy-clean photography ready - no logos or text baked into the image.
Most of your traffic is mobile, where image assets render most often.
You want visual differentiation from competitors running all-text ads.

Use Structured Snippets when

You want to show breadth - many models, services, or destinations - in one glance.
You don't have clean product photography and don't want the auto-selection risk on images.
Your value proposition is coverage ('we handle X, Y, Z') rather than appearance.
You need a lightweight asset that renders as text consistently regardless of device.

Common questions.

Can I use both image assets and structured snippets on the same ad?

Yes, they're unrelated slots and commonly run together - the image adds a visual, the snippet adds a coverage line, and neither displaces the other.

Why did Google reject my uploaded image?

The usual causes are text overlay covering too much of the frame, a collage of multiple images stitched together, or a logo placed in a corner - all of which read as a banner ad rather than a product photo. A plain, uncluttered photograph passes far more reliably.

Can I write my own header for a structured snippet?

No, you must pick from Google's predefined header list like Brands, Types, or Services - the header itself can't be customized, only the values underneath it.

Why doesn't my image asset ever show even though it's approved?

Google decides whether to render it per auction based on predicted performance lift and available placement space, so an approved image can sit unused if the system doesn't expect it to help. There's no manual override beyond keeping the image compliant and giving it time to accumulate performance data.

Or stop choosing between them.
