Image SEO for Google AI Mode, Lens and Visual Search: A Small Business Checklist

Last updated: November 2026 · Written by Adrian Prokopiec, 20 Minute Marketing · 10 min read

This guide is for Australian small business owners who manage their own website, whether you're a tradie with a gallery of jobs, a retailer with product photos or a clinic with photos of your rooms. You'll learn what visual search in Google actually is in 2026, what Google says about how it understands images, and a step-by-step checklist you can work through page by page.

It's focused on images. If you want the broader picture of getting your business into AI answers, read our guide to ranking in AI Overviews and voice search and our explainer on what answer engine optimisation (AEO) is. This post also sits within our wider guide to the AI tools every small business needs.

What is visual search in Google in 2026?

"Visual search" covers a few different Google features that now overlap:

• Google Images: the classic image results, at Google Images or the Images tab.
• Google Lens: searching with your camera or a photo, for example pointing your phone at a cracked roof tile or a plant you want to identify.
• AI Mode: Google's conversational search. You can read Google's own overview of how Google AI Mode works. It launched in Australia on 8 October 2025, and the Google Australia announcement describes it as multimodal: people can ask by text, voice or image, including snapping a photo and asking a question about it.

Google has also expanded the visual side of AI Mode. In its September 2025 post on how AI Mode can help you search and explore visually, Google explains that AI Mode can return a range of visual results, each with a link back to the source, and uses a "visual search fan-out" technique to understand more of what's in an image. That post covers features first rolled out in the US, so not every visual or shopping feature is necessarily live here yet. Industry sites such as Search Engine Land track these rollouts as they happen.

The practical takeaway: when someone in Geelong asks AI Mode "show me modern bathroom renovations with black tapware", the images that appear come from websites. Those images need to be findable, understandable and worth showing. Yours can be among them.

How Google understands your images

You'll read plenty of confident claims about Google "seeing" every detail of your photos and ranking them on engagement. Google doesn't publish its ranking systems, so treat those claims with caution. What Google does publish is clear guidance in its image SEO best practices. The main points:

• Google finds images in HTML img elements. It says it doesn't index CSS background images, so a hero photo set as a background won't count.
• Alt text is the most important metadata. It helps both accessibility and Google's understanding of the image.
• Context matters. Google uses captions, page titles and nearby text to understand what an image is about.
• File names give small clues. A name like "black-tapware-bathroom-renovation.jpg" is better than "IMG00023.jpg".
• Quality and speed both count. Sharp images appeal to users, and compressed images keep pages fast.

And for AI features specifically, Google's documentation on AI features says there are no extra requirements or special markup to appear in AI Overviews or AI Mode. Standard SEO, plus high-quality images that support your text, is the recipe. That's good news: it means this is work you can actually do.

Why original photos beat stock images

If a hundred builders all use the same stock photo of a smiling couple in a new kitchen, there's no reason for Google to show yours rather than any of the others. Original photos are unique, they show your real work, and they answer the question a customer actually has: "Can this business do what I need?"

Some examples of images worth taking for different businesses:

Photos that answer a question work especially well. An electrician might photograph a modern safety switch next to an old fuse box with a caption explaining the difference. That's the kind of image that can appear when someone asks about it.

A word on AI-generated images: they can be handy for illustrations or blog graphics, as our guide to using AI image generators on your website explains, but never use them to depict work you've done. That misleads customers, and under the Australian Consumer Law, misleading representations about your services are a real risk.

Do this in 20 minutes: optimise one page's images

Don't try to fix your whole site at once. Pick your most important service or product page and work through this list.

1. Swap stock for real (5 minutes). Replace any stock photos with your own. Two or three strong, relevant photos per service page is plenty.
2. Rename the files before uploading (3 minutes). Use short, descriptive, hyphenated names: "timber-deck-oiling-ringwood.jpg". Most website builders keep the file name in the image URL, so rename on your computer or phone first.
3. Write specific alt text (4 minutes). Describe what's in the image as if to someone who can't see it: "Freshly oiled spotted gum deck with built-in bench seating" beats "deck photo". Mention the location only if it's genuinely part of what the image shows. Don't cram in keywords.
4. Put each image next to relevant text (3 minutes). An image of a deck should sit beside the paragraph about decks, ideally with a short caption.
5. Compress and resize (3 minutes). Export photos at the size they're displayed, not straight off a 48-megapixel phone. Use JPEG or WebP for photos; Google supports BMP, GIF, JPEG, PNG, WebP, SVG and AVIF.
6. Check it's a real image (2 minutes). If your theme sets important photos as CSS backgrounds, Google won't index them. Use a normal image block instead.

Repeat for one page a week and in a couple of months your whole site is done. If page speed is a problem, our guides to fixing website speed for free and WordPress speed fixes cover compression and lazy loading in more detail.

The technical bits: sitemaps, structured data and metadata

Image sitemaps

An image sitemap helps Google find images it might otherwise miss, such as ones loaded by JavaScript. Google's documentation on image sitemaps says it's fine either to add image tags to your existing sitemap or create a separate one. Many platforms, including Shopify and popular WordPress SEO plugins, include images in sitemaps automatically, so check yours before building anything. Our Shopify SEO guide covers the Shopify side.

Structured data

Structured data won't make a photo rank on its own, but it helps Google understand what a page is about, and Google says it can make images eligible for rich results and badges in Google Images. Product pages should use Product markup with an image property; local businesses should use LocalBusiness markup with a logo and image. Our guide to schema markup for small business shows what to add and why.

Image rights metadata

If you care about credit for your photos, Google's page on image metadata in Google Images explains how creator, credit line and copyright fields (embedded as IPTC metadata or added as structured data) can be shown in Google Images. Google is clear that it doesn't guarantee this will appear, and it doesn't describe it as a ranking factor. It's a nice extra, not a priority.

For the foundations underneath all of this, Google's SEO Starter Guide and Search Essentials are worth bookmarking. If Google isn't indexing your pages at all, images won't save you, so start with fixing the technical errors that make your website invisible to Google.

Don't forget your Google Business Profile and social photos

For local searches, many of the images people see come from your Google Business Profile (formerly Google My Business), not your website. Add exterior, interior, team and work photos, and keep adding new ones as you finish jobs. Our Google Business Profile optimisation guide walks through the full setup, and we explain why your Google Business Profile is a marketing powerhouse in more depth. Wondering whether location tags in photos matter? See do geotagged photos help local SEO.

Photos you post on Instagram, TikTok or Facebook mostly help you on those platforms. If a photo is good enough to share there, it's worth putting on your own website too, properly named and described, where it can work for you in Google. Local search ties all of this together, which is why our local SEO tips for small business treat photos as part of the bigger system.

How to measure your image search performance

• Search Console: in Google Search Console, open the Performance report and change the search type to Image. You'll see which queries and pages earn image impressions and clicks. If you're new to it, start with our 20-minute Search Console guide and avoid these common Search Console mistakes.
• Analytics: in Google Analytics, check whether visitors from Google search convert into enquiries or sales. Traffic from AI Mode isn't always separated out, so focus on the overall trend for the pages you've improved.
• A simple check: once a month, search for your main services the way a customer would, including in AI Mode, and note whose images appear. If competitors' photos keep showing, look at what they do differently.

Once you've got image data, look for pages with lots of impressions but few clicks. Our guide to finding hidden traffic in Search Console shows how to spot and act on those opportunities.

If you want to learn the whole job properly, our SEO course covers image optimisation alongside the rest of on-page SEO, and the website design course shows how to build pages where images are set up correctly from the start. You can also compare all 20 Minute Marketing courses or start with the Essentials course.

Frequently asked questions

Is there special markup to get my images into Google AI Mode?

No. Google says there are no additional requirements or special optimisations needed to appear in AI Overviews or AI Mode. Standard image SEO applies: original images, descriptive file names, useful alt text, relevant surrounding text and fast pages.

Do I need professional photography?

Not usually. A modern phone in good light produces images that are more than good enough. Original, sharp and relevant matters far more than expensive equipment.

Can I use stock photos?

You can, but they won't help you stand out because the same images appear on many other sites. Use original photos for anything that shows your work, products or premises.

How long should alt text be?

Long enough to describe the image specifically, usually a short sentence. Describe what's actually shown and avoid stuffing in keywords or suburb lists.

What image format should I use?

JPEG or WebP for photos, PNG for graphics that need transparency. Google supports BMP, GIF, JPEG, PNG, WebP, SVG and AVIF. Compress files so pages load quickly.

Can I optimise images that are already on my site?

Yes. Update the alt text and captions and improve surrounding text straight away. Renaming files usually means re-uploading the image, so do that for your most important pages first.
