Multimodal Search

Traditional search was text-only: a user typed a query and got back text results with text snippets. Multimodal search processes several media types at once inside a single AI response — text, images, sometimes audio — rather than treating each as a separate signal to be indexed and matched independently.

Google's Gemini is natively multimodal, meaning it can process and understand images, audio, and text together, in the same pass. For a local business, that changes what actually counts as content worth optimising:

• A hotel's pool photo in its GBP contributes to a "hotels with pools" recommendation, even if the word "pool" never appears anywhere in the hotel's text description
• A restaurant's dish photos contribute to cuisine identification and specific-dish recommendation accuracy
• A clinic's interior photos contribute to how confidently a model recommends it as "clean" or "modern" — an inference the model draws from the image, not from a written claim

How multimodal AI reads local business content

A multimodal model doesn't just check whether a photo exists — it extracts attributes from what's actually in the image. Outdoor seating visible in a restaurant photo, specific medical equipment visible in a clinic photo, room layout visible in a hotel photo: all of these get read as facts about the business, on the same footing as anything written in the GBP description. This means a business can genuinely under- or over-represent itself through photos alone, independent of what its text says. A gym with modern equipment but only blurry, poorly-lit photos of it is telling the model something worse than the truth.

Multimodal signals for local businesses

Photos are the most immediately actionable multimodal signal available today. Specific, real photos — not stock imagery — carry far more extractable information than generic images do, because a stock photo of a generic dental chair tells a model nothing distinguishing about that particular clinic.

Videos add a further layer. GBP accepts video uploads, and video content provides multimodal signals photos alone can't — a clinic video showing a doctor's consultation style, for instance, contributes to "communicative doctor" recommendation confidence in a way a static photo never could.

Why this matters more than it used to

Text-based SEO advice — write more content, use the right keywords — assumes the ranking system is reading words. Multimodal search partially breaks that assumption: a business's photo gallery is now doing real optimisation work whether anyone at the business intended it to or not. Ignoring photo quality isn't a neutral choice anymore; it's leaving a channel of AI-readable information either blank or filled with generic stock imagery that actively works against specific, accurate recommendation.

Common mistakes

The most common mistake is uploading the same handful of stock or promotional images across every location of a multi-location business, which gives a multimodal model nothing distinguishing to extract about any specific branch. The second is treating photo uploads as a one-time task at GBP setup rather than an ongoing input — a clinic that renovated two years ago and never updated its interior photos is still being represented by a room that no longer exists.

Adjacent concepts

Multimodal search sits alongside semantic search → as one of the ways AI-era search moves past pure keyword matching. GBP AI Optimization → covers the practical GBP-level work — photos, videos, attributes — that feeds multimodal signals directly. Grounding → is the mechanism by which a model ties its multimodal read of a photo back to a specific, verified business entity rather than a generic category.

India context: Indian local businesses with high-quality, specific photos — not stock images — have a genuine advantage in multimodal AI search over competitors with generic or sparse photo galleries. Dish photos for restaurants and treatment-room photos for clinics are particularly high-value multimodal signals, precisely because they're the images most likely to be missing or generic on a typical Indian GBP.

Example: A Pune boutique hotel replaced ten years of dim, low-resolution photos with a proper shoot showing its rooftop pool, room interiors, and breakfast spread. Within weeks, it began appearing in Gemini-generated answers to "hotels with a pool near Koregaon Park" — a query its old photo gallery had given the model nothing to confirm, regardless of what the hotel's text description claimed.
