Every month, over 20 billion visual searches are performed through Google Lens alone (Google/DemandSage). Visual search is fundamentally changing how customers discover and purchase products. Instead of typing search terms, users photograph a product - and AI finds matching results in seconds. For e-commerce merchants and online shop operators, this means: those who don't optimize their product images and data structures for visual search are losing a rapidly growing sales channel to competitors.
What Is Visual Search?
Visual search - also known as image recognition search - enables users to search using an image instead of text. The user photographs a product, uploads a screenshot, or points their camera at an object. AI-powered algorithms analyze the visual features of the image - colors, shapes, textures, patterns - and match them against an indexed product database.
The crucial difference from traditional image search: In conventional Google image search, the user enters text and receives images. In visual search, the image itself is the query. This solves a fundamental problem in e-commerce: customers can find products they know visually but cannot describe in words.
A customer sees a dress they like on Instagram. Instead of trying to describe it in words ("red dress with floral pattern and V-neck"), they simply take a screenshot and search via Google Lens. In under three seconds, the AI shows identical and similar products from various online shops - including price comparison.
How AI Image Recognition Works Technically
The technology behind visual search is based on Convolutional Neural Networks (CNNs) - a form of deep learning developed specifically for image processing. CNNs recognize patterns at multiple levels: first edges and basic shapes, then textures and complex patterns, and finally complete objects (Pinecone).
The technical process in practice: The CNN model generates a numerical vector (embedding) for each product image. Similar images produce vectors that are close together in vector space. When a customer uploads a photo, it is also converted into a vector and matched against the product database. Leading algorithms achieve recognition accuracy of 85% (Gartner), with object detection reaching 93% (MIT).

Google Lens: 20 Billion Searches Per Month
Google Lens is by far the most widely used visual search platform with over 20 billion visual searches per month (Google/DemandSage). Of these, approximately 4 billion are directly related to shopping and product search (Imagga). That equals more than 3,086 search queries per second (AllOutSEO).
Pinterest Lens records 600 million monthly visual searches (Imagga). Amazon reports a 70% year-over-year increase in visual product searches (eMarketer). The total number of image-based product searches rose to 650 million monthly in Q1 2024 alone - an increase of 38% compared to the previous year (Imagga).
| Platform | Monthly Searches | Key Feature |
|---|---|---|
| Google Lens | 20 billion | Market leader, integrated in Android and Chrome |
| Pinterest Lens | 600 million | 7.2% of Google Lens results come from Pinterest |
| Amazon StyleSnap | 70% YoY growth | 40% higher average order value |
| Zalando AI Assistant | 500,000+ users | 18% more engagement after integration |
Conversion and ROI: The Business Case
The numbers speak clearly: Visual search increases conversion rates by up to 27% (Statista). Products with 3D and AR representations achieve up to 94% higher conversions (Shopify). At the same time, returns drop by 22% (Shopify), because customers can better assess the product visually before purchase.
The return on investment is remarkable: PrettyLittleThing achieved a 269% ROI in direct revenue with visual search (Salesfire). Yestersen, a home decor marketplace, recorded a 186% conversion uplift (Salesfire). Average order value increases by 12-20% (BigCommerce/Best Colorful Socks), and website session duration by 33% (Google Analytics).
Gartner predicts that brands redesigning their websites for visual search can increase digital revenue by 30% (Gartner). The visual search market is growing at an annual rate of 17-20% (Grand View Research).
Implementation: Visual Search in Your Online Shop
Integrating visual search doesn't require a complete rebuild. For Shopware shops and other shop systems, various approaches are available - from simple Google Merchant Center optimization to full API integration.
- Optimize Google Merchant Center: Maintain product images and structured data in Google Merchant Center - the fastest path to Google Lens visibility
- Upgrade product images: Minimum 2000x2000 pixels, multiple angles, clean background, consistent lighting
- Implement structured data: Add Product schema with JSON-LD for all products (see Structured Data section)
- Integrate visual search API: Add camera icon next to the search bar, support image upload and camera capture
- Index product catalog: Generate vector embeddings for all product images and build similarity search
- Test and optimize: A/B test visual search placement, monitor search accuracy
Implementation time varies by approach: A basic integration via third-party APIs is typically achievable in 2-4 weeks (VWO). Custom solutions with proprietary ML models require 3-6 months of development time.
Image Optimization: Best Practices for Visual Search
The quality of your product images determines success in visual search. 93% of online shoppers consider visual appearance the primary purchasing factor (Envive.ai). Products with professional photos achieve 33% higher conversion rates (Spyne.ai).
Technical Requirements
Minimum 2000x2000 px, WebP format preferred, sRGB color space, width and height declared in HTML
Photography Standards
White background for main images, multiple angles, consistent lighting, detail shots
Filenames and Alt Text
Descriptive filenames (e.g., blue-leather-handbag-front-view.webp), keyword-relevant alt text
Performance
Lazy loading, CDN delivery, responsive srcset, compression without visible quality loss
Particularly important for SEO and visual search: According to a Backlinko study of 65,388 Google Lens searches, approximately one-third of all Google Lens results appear from the top quarter of a webpage. Position your key product images in the upper section of the page. Additionally, 90% of pages ranking in Google Lens are mobile-friendly (Backlinko).
Structured Data: Schema Markup for Images
Structured data is key to visibility in visual search. Google Lens uses Merchant Center data for product identification (Backlinko). Pages with schema markup achieve 20-40% higher click-through rates (1SEO Digital Agency).
{
"@context": "https://schema.org",
"@type": "Product",
"name": "Blue Leather Handbag Classic",
"image": [
"https://shop.example.com/images/handbag-blue-front.webp",
"https://shop.example.com/images/handbag-blue-side.webp",
"https://shop.example.com/images/handbag-blue-detail.webp"
],
"description": "Premium handbag made from Italian leather...",
"sku": "HB-BLUE-001",
"brand": {
"@type": "Brand",
"name": "Brand Name"
},
"offers": {
"@type": "Offer",
"price": "189.00",
"priceCurrency": "EUR",
"availability": "https://schema.org/InStock"
}
}Supplement your Product schema with multiple high-resolution images from different perspectives. Google recommends at least three image variants per product. Ensure alt texts and schema data are consistent - 11.4% of Google Lens results had matching alt text (Backlinko).
AR Product Visualization: The Next Level
Augmented Reality (AR) adds a crucial dimension to visual search: customers can virtually place products in their own environment before purchasing. The AR market in e-commerce is growing at 35.8% CAGR from USD 5.9 billion (2024) to a projected USD 38.5 billion by 2030 (Grand View Research).
71% of shoppers say they would shop more frequently if AR were available (BrandXR). The impact on return rates is impressive: IKEA Place shows 35% lower returns compared to purchases without AR (Imagga). Brands using AR for product visualization report up to 40% fewer returns overall (BrandXR).
AR-optimized product pages achieve 21% higher revenue per visit and 13% higher average order value (BrandXR). Shopify shops with 3D/AR content see 94% higher conversions (Shopify).
Industry Focus: Fashion and Furniture Lead the Way
Visual search is not equally relevant across all industries. Products where visual attributes - color, pattern, style, shape - drive purchase decisions benefit disproportionately.
| Industry | Visual Search Usage | Key Metric |
|---|---|---|
| Fashion & Apparel | 86% of VS users search for clothing | 269% ROI (PrettyLittleThing) |
| Furniture & Interior | 85% use VS for furniture search | 186% CVR uplift (Yestersen) |
| Beauty & Cosmetics | Virtual try-on growing strongly | 30% more conversions (BrandXR) |
| Home & Living | 31% choose VS for home decor | 35% fewer returns (IKEA) |
In the fashion segment, 86% of visual search users specifically use the technology for clothing search (Best Colorful Socks). Amazon StyleSnap enables deconstructing entire outfits from a photo into individual shoppable products - users show a 40% higher average order value (Imagga). Zalando reached 500,000+ users with its AI assistant and an 18% increase in engagement (Cross Border Magazine).
In the furniture segment, IKEA sets benchmarks with its Place app: customers virtually place furniture in their rooms, reducing return rates by 35% (Imagga). 60% of Pinterest users make home decor purchase decisions on the platform (Pinterest). For Shopware shops in the interior segment, the combination of visual search and AR visualization opens significant growth potential.
GDPR and Data Privacy in Visual Search
Processing user-generated images raises important data privacy questions that must be carefully addressed, particularly in the European market.
When users upload images for visual search, merchants must answer: Where are images stored? How long are they retained? Are they used for model training? GDPR requires clear privacy policies, data minimization, and explicit consent. Many cloud APIs process images without long-term storage - but this should be verified per provider (Intelliarts).
- Transparent privacy policy for image upload functions
- Data minimization: store images only as long as necessary
- Review data processing by cloud API providers (e.g., Google Cloud Vision, AWS Rekognition)
- Consent management per GDPR requirements
- No use of uploaded images for AI training without explicit consent
The Future: Multimodal Search and Gen AI
Visual search is evolving rapidly. 85% of consumers now expect e-commerce platforms to offer visual search capabilities (PwC). 62% of Gen Z and Millennials want visual search features (Lyxel & Flamingo). 85% of retailers plan visual search implementation by 2027 (Statista).
The next evolution is multimodal search - combining image, text, and voice in a single search query. A user photographs a sofa, for example, and adds: "Is this available in green?" The AI automation of these processes will become a decisive competitive factor for online retailers.
For e-commerce merchants, this means: investing in high-quality product images, structured data, and visual search optimization pays off multiple times - for traditional SEO, for Google Shopping via the Merchant Center, and for the growing number of visual search queries.
This is how your online shop with visual search could look:
Fashion & Lifestyle Shop
Interior-Shop mit Raumplaner
Kosmetik-Shop mit Hautanalyse
In traditional image search, the user enters text and receives images as results. In visual search, the image itself is the query. The user photographs a product or uploads an image, and AI finds visually similar products. Visual search thus solves the problem that customers cannot describe products in words.
Yes, particularly through optimization for Google Lens, which works without proprietary visual search infrastructure. Through high-quality images, Product schema markup, and optimized entries in Google Merchant Center, even smaller shops can benefit from the 20 billion monthly Google Lens searches.
Duration depends on the chosen approach. A basic optimization for Google Lens (image quality, schema markup, Merchant Center) is typically achievable within a few days. An API-based visual search integration via third-party providers typically takes 2-4 weeks. Custom solutions with proprietary ML models require 3-6 months of development time.
Fashion and apparel lead with 86% usage share, followed by furniture and interior (85%). Generally, all industries where visual attributes such as color, pattern, style, or shape influence purchase decisions benefit. Beauty, jewelry, and home decor also show high visual search adoption.
Key steps: Implement Product schema markup with JSON-LD, maintain product images in Google Merchant Center, use descriptive alt texts and filenames, ensure mobile-friendly pages, position product images in the upper page section, and use high-resolution images with clean backgrounds.
When users upload images for visual search, GDPR requirements apply: transparent privacy policy, data minimization (store images only as long as necessary), review cloud API providers for data processing, and no use of images for AI training without explicit consent.
