How Does Google Lens Work? What It Searches, and How Your Images Show Up

By the ImageSEO Team · updated October 2026 · about 8 min read

Quick answer: Google Lens lets you search with a picture instead of words. You point your camera at something, upload a photo, or select part of a screen; Lens works out what’s in the image, then searches Google for matching images, products and web pages, and can add an AI-generated answer if you ask a question. Google says Lens is used for nearly 20 billion visual searches a month, and about 20% of them are shopping-related. For website owners, the results come from pages Google has already indexed, so your images show up through the same basics as Google Images: real <img> elements, descriptive alt text and useful text around them. Since 24 September 2026 you can see this traffic in Search Console under the new “multimodal” search type.

Where you find Google Lens

Lens isn’t a separate website you visit. It’s built into the places people already search:

• The Google app on Android and iPhone (the camera icon in the search bar).
• Chrome, including “Search this image” when you right-click a picture on desktop.
• Google Photos and the camera app on some Android phones.
• Circle to Search on Android, where you circle anything on screen.
• Google Search itself, where you can upload an image instead of typing.

How Google Lens works, step by step

Google hasn’t published the inner workings or ranking factors of Lens. What it has described publicly fits into three steps:

1. Understand the image. Lens identifies what’s in the picture: an object, a plant, a landmark, a product, a piece of text. You can narrow it down by cropping to one part of the image.
2. Search with it. It looks for matching and related results across Google: visually similar images, product listings with prices and stores, and web pages about what it recognised. You can add words to refine the search, for example a colour or “near me”.
3. Answer, if asked. Since 2024 you can point the camera, ask a question out loud or in text, and get an AI Overview built from web results. In October 2024 Google also started testing video: you record a short clip and ask about what’s moving in it.

What it doesn’t do: Lens doesn’t read a special “Lens tag” on your site. Like the rest of Google Search, it can only show your page if Google has crawled and indexed it.

What people use Google Lens for

How your images show up in Google Lens

Because Lens draws on Google’s index, the guidance Google publishes for Google Images is the best guide you have. Google hasn’t confirmed any Lens-only signals, so be wary of articles that list “Lens ranking factors” with weights.

• Use real image elements. Google says standard <img> elements help it find and process images, and that it doesn’t index images set as CSS backgrounds. A product photo used as a background image is invisible to search.
• Write descriptive alt text. Google calls alt text the most important attribute for giving an image extra metadata. Describe what’s actually in the picture: “brown leather crossbody bag with brass buckle”, not “bag” or “IMG_4273”.
• Put the image next to relevant text. Google uses the page’s content, including captions, to understand images. A product photo on a page with the product name, specs and price is far easier to match than the same photo in an unlabelled gallery.
• Give the file a descriptive name. Google says file names give it light clues about the subject. It’s a small signal, but free to get right before upload.
• Use product structured data on product pages, so the product’s name, image, price and availability are machine-readable for shopping results.
• Use good, original photos. A clear image of the actual product or place gives Lens something to match; a stock photo that appears on thousands of sites gives it little reason to pick yours.

How common are the gaps? In our 2026 crawl of the homepages of the 10,000 most-visited websites, 11.3% of 306,634 images had no alt attribute at all, and only 46.4% of file names described the image. Even the biggest sites leave Lens with little to go on.

How to see your Google Lens traffic in Search Console

Until recently you couldn’t separate visual searches from other Google traffic. On 24 September 2026, Google added a multimodal search type to Search Console. It covers searches made with Lens, Circle to Search on Android, image uploads to Google Search, and Chrome’s right-click “Search this image”.

1. Open Search Console and go to Performance → Search results.
2. Click the Search type filter and choose the multimodal option.
3. Look at the Pages tab to see which pages appear for visual searches, and compare them with your Image search results.
4. The same filter is available in the Generative AI features report.

Google says the data rolled out globally from 24 September 2026 and only appears if your site actually gets traffic from these searches, so an empty report on a small site is normal.

A quick Google Lens checklist for your site

• Every meaningful image is an <img> element with descriptive alt text.
• Product and article images sit next to text that names what they show.
• File names describe the image (brown-leather-crossbody-bag.jpg, not DSC_0421.jpg).
• Product pages carry product structured data with an image.
• Your images and pages are in your sitemap and actually indexed. Check with URL Inspection; for a whole-sitemap audit we recommend SitemapFixer.
• You check the multimodal search type in Search Console once a month.

On WordPress, the first and third items are the slow ones to do by hand. The ImageSEO plugin writes alt text and descriptive file names for every image, on upload or for the whole media library. For the background on everything else, see our image SEO guide and how image sitemaps work.

Frequently Asked Questions

Yes. Lens is part of Google Search and is built into the Google app, Chrome and Google Photos at no cost.

How do I use Google Lens?

In the Google app, tap the camera icon in the search bar and point it at something or pick a photo. In Chrome on desktop, right-click an image and choose “Search this image”. On many Android phones you can also long-press the home button or navigation bar and circle what you want to search.

Does Google Lens use alt text?

Google hasn’t published how Lens ranks results. It does say alt text is the most important attribute for helping it understand an image in Search, and Lens results come from Google’s index, so descriptive alt text is the safest bet.

How many people use Google Lens?

Google said in October 2024 that Lens is used for nearly 20 billion visual searches every month, and that about 20% of them are shopping-related.

Can I see Google Lens traffic in Search Console?

Yes, since 24 September 2026. Use the multimodal search type filter in the Performance report. It combines Lens, Circle to Search, image uploads and Chrome’s “Search this image”.
