Image Assets vs Lead Form Assets: Add a Photo or Capture a Lead
In short: Both attach visual or interactive real estate to a search ad, but they change different parts of the experience. Image assets add a picture beside the text to make the ad more noticeable and give a preview of the product or service; nothing changes about where the click goes. Lead form assets replace the click's destination with a form, generating a conversion without a site visit at all. One is about getting noticed, the other is about closing on the spot. Chooser: use image assets when you want the ad itself to stand out visually, and lead form assets when you want the click to end in captured contact details instead of a landing page.

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.
Full definitionLead Form Assets
Attaches a form directly to a Google ad so someone can submit contact details without visiting your site, formerly called lead form extensions.
Google shows a hosted form after the click, prefilled from the signed-in account, and you retrieve the leads by webhook or CSV download. It suits mobile-heavy searches where a slow landing page loses people. Two things trip advertisers up: leads never reach your CRM unless the webhook is wired and monitored, and the low friction that lifts volume also admits unqualified submissions, so qualifying questions matter.
Full definitionSide by side.
The differences that actually change what happens in your account.
| Image Assets | Lead Form Assets | |
|---|---|---|
| What changes in the ad | A square or landscape photo appears alongside the headlines and description. | The ad becomes submittable - tapping it opens a form instead of a webpage. |
| What happens after a click | Normal - the searcher still lands on your chosen page. | Nothing loads externally; submission inside the form is the conversion. |
| Content review focus | Image quality and composition rules - no text overlays, no collages, no corner logos. | Data collection and privacy policy compliance, reviewed more heavily in sensitive verticals. |
| What it needs to be approved | A clean product or service photo meeting Google's size and content specs. | A published form with required fields and a linked privacy policy. |
| Reporting it adds | None of its own - it has no separate conversion count. | Its own conversion count tracked inside Google Ads. |
| Typical rejection reason | Marketing banner style creative with heavy text, which reads as a display ad, not a photo. | Missing or invalid privacy policy link, or a form asking for data the vertical restricts. |
| Device bias | Shows mainly on mobile results where visuals stand out more. | Especially valuable on mobile, where a slow landing page load loses the most people. |
What actually separates them.
Image assets change how the ad looks; lead form assets change what happens when the ad is clicked.
Google reviews image assets for visual composition - no collages, overlays, or logos - while it reviews lead form assets for data handling and privacy compliance.
An image asset has no conversion of its own to track, while a lead form asset generates its own conversion count separate from your site's.
Rejected image assets fail on creative specs; rejected lead form assets usually fail on missing privacy policy links or restricted data fields.
Image assets can run alongside a lead form asset on the same ad, since one changes appearance and the other changes the destination - they don't compete for the same function.
Which one should you use?
Use Image Assets when
- Your product or service is visually distinctive and a photo would help someone recognize it in the results.
- You're seeing lower click-through rates on mobile and want the ad to physically take up more space.
- You have a clean, policy-compliant photo ready - no logos, no text baked into the image.
- You still want traffic to land on your own site rather than end in an on-ad form.
Use Lead Form Assets when
- You want the click to end in captured contact details, not a pageview.
- Your landing page is slow or unfinished and would cost you conversions if people had to wait for it.
- The ask is simple enough to fit in a short form - name, phone, one or two qualifiers.
- You have a process ready to follow up on leads pulled from Google's dashboard or webhook.
Common questions.
Can I use a banner-style image with text on it for an image asset?
No, Google's policy for image assets specifically excludes heavy text overlays, collages, and corner logos because the format is meant to read as a real photo next to a text ad, not as display creative. Banner-style images built for other channels usually fail review and need to be swapped for a plain product or service shot.
Does adding an image asset increase my cost per click?
No, image assets don't carry a separate cost - any click on the ad is billed the same way regardless of whether an image showed with it. What an image can influence is click-through rate and Ad Rank, which affects how often and where the ad shows, not the price of an individual click.
Can I run a lead form asset without a website at all?
Largely yes for the capture step itself, since the form is hosted by Google and the conversion happens on submission, but you'll still need a privacy policy URL to link in the form, which typically requires at least a minimal web presence. Most advertisers also want a real site for retargeting and credibility even if the primary conversion path is the form.
