Google Lens and Visual Search: How to Optimise Images for 2025

Google Lens processes over 12 billion visual searches monthly. As cameras become the primary search interface for younger generations, optimising for visual search is increasingly important. This guide covers what we know about how Google Lens ranks images.

What Is Google Lens?

Google Lens is Google's visual search tool. Users point their camera at an object, product, plant, text, or QR code — and Google identifies it and shows related information, shopping results, and similar images. It's embedded in the Google app, Pixel phones, and Google Images.

How Google Lens Affects E-commerce

For product-based businesses, Google Lens is highly valuable. When a consumer sees a product they like (in a store, on a friend, in a magazine), they can photograph it and immediately find where to buy it online. Products that appear in Google Lens results can capture this high-intent traffic.

Product Schema for Google Lens

Adding Product structured data to your product pages significantly improves their chances of appearing in Google Lens shopping results. The minimum required fields are: name, image, offers (price, currency, availability).

Image Quality for Visual Search

Google Lens needs high-quality images to identify products accurately. For product pages: use images of at least 1000px on the shortest side, ensure the product is the clear focus with minimal background clutter, and shoot on plain backgrounds where possible.
