Visual and multimodal search moved from “nice to have” to “must optimize” over the past year. As users increasingly search with a mix of images, short video, text, and even gestures, content that’s only optimized for keywords is losing ground. Google’s 2024 updates brought Circle to Search and Multisearch with AI-generated overviews into mainstream usage, while YouTube Shorts has been testing Lens-driven discovery within videos. Bing continues refining multimodal indexing and proactive submission signals. For marketers and SMBs, the practical implication is clear: media metadata, structured data, accessibility, and performance now govern discoverability across search and social surfaces.

What changed in 2024–2025

Google broadened how people can search. The January 2024 announcement introduced gesture-based discovery and multimodal query capabilities, including Circle to Search and AI-powered Multisearch (Google Search Blog, 2024). This pushed image-first and video-aware queries into everyday workflows.
Social video is becoming a search interface. Reputable trade press reported that YouTube Shorts began testing Lens integration so viewers could pause a Short and search objects or text on screen; availability has been described as experimental/beta. See YouTube adds Lens search to Shorts (Social Media Today, 2025) for context.
Bing is reinforcing multimodal discoverability and real-time freshness via IndexNow. If your site updates often or has many media pages, pushing URLs proactively can help ensure rapid indexing. The official steps to implement are documented in IndexNow get started (Microsoft/Bing).

Why it matters: These shifts elevate entity-aware and media-grounded answers over plain-text matches. Visibility now depends on whether your images and videos are understandable to crawlers, semantically aligned with page topics, accessible to users, and delivered fast.

Why this matters for marketers and SMBs

Media is now a ranking input. Google’s site-owner guidance explains how images and videos can qualify for richer presentation and better surfacing when implemented correctly. The Image SEO best practices (Google Search Central) and Video guidance with VideoObject outline how descriptive metadata, sitemaps, and watch pages impact discoverability.
Performance affects whether media gets seen. Core Web Vitals quantify user experience; heavy media can slow pages and hurt visibility. Google’s thresholds for LCP, CLS, and INP are documented in Core Web Vitals (Google Search Central, updated 2024 when INP replaced FID). Meeting these standards improves the odds that your media-rich pages surface well.
Accessibility and trust signals carry more weight. Alt text, captions, and clear provenance are both user-friendly and machine-readable. They help AI systems ground answers to reliable sources and improve inclusion.

The practitioner playbook: make your media findable and fast

Below is a pragmatic roadmap you can implement without heavy engineering.

1) Images: descriptive, responsive, licensed

Use standard HTML <img> with descriptive, natural alt text that reflects the page topic; avoid keyword stuffing.
Place images near relevant copy; use high-quality, topical visuals.
Make images responsive with srcset/sizes; serve modern formats (WebP/AVIF) and compress effectively.
Keep images crawlable (no robots.txt blocks, return 200 status) and consider image sitemaps if you publish at scale.
When applicable, include creator and license metadata to support provenance.
Validation: Review Google’s Image SEO best practices and test representative pages with URL Inspection in Search Console.

2) Video: captions, watch pages, and VideoObject

Provide accurate captions and, where feasible, transcripts for accessibility and keyword grounding.
Publish a dedicated, indexable watch page per video; ensure thumbnails and media files are accessible to Googlebot.
Implement VideoObject structured data with required properties (name, description, thumbnailUrl, uploadDate, and either contentUrl or embedUrl); add recommended properties like duration.
Add video entries to XML sitemaps; keep titles and descriptions clear and consistent with visible content.
Validation: Use the Video guidance and VideoObject docs and the Rich Results Test; monitor the Video Indexing report in Search Console for status and errors.

3) Structured data where it counts (Product, HowTo, Recipe)

Align markup with the visible page; include required properties and avoid misleading markup.
Validate regularly and monitor Rich results reports in Search Console if you’re eligible.
Practical tip: prioritize Product on ecommerce pages, HowTo on step-by-step content, and Recipe for culinary content; ensure images/video support the topic.
Reference: Type-specific guidance is linked from Google’s Search Central. Start with the Image and Video docs above and expand as relevant.

4) Accessibility & provenance

Alt text should describe the image’s purpose relative to the page; images used as links need alt attributes reflecting the target.
Captions/subtitles are essential for short-form video and tutorials; they also boost searchability on YouTube and social.
Maintain creator/licensing metadata (e.g., IPTC) when applicable to support trust and correct reuse.

5) Performance: keep media fast (CWV)

Aim for LCP ≤ 2.5s, CLS ≤ 0.1, and INP ≤ 200ms at the 75th percentile.
Lazy load non-critical images/video; preconnect/preload critical assets; serve via a CDN.
Use PageSpeed Insights (CrUX data) to validate improvements and track regressions.

6) Social-as-search: make short videos “searchable”

Add accurate captions and on-screen text for key moments; ensure recognizable objects and landmarks are clearly visible.
Use strong thumbnails and chapter markers where supported.
Vertical format and concise storytelling improve consumption; follow platform policies and test different hooks.

Example workflow: from draft to validated multimodal content

Draft and assemble your blog with embedded images and a short explainer video.
Add descriptive alt text to each image; supply captions/subtitles for the video.
Implement appropriate structured data (e.g., VideoObject on the watch page; Product/HowTo/Recipe where relevant) and submit sitemaps.
Validate pages with the Rich Results Test; check Video Indexing and Performance in Search Console; run PageSpeed Insights to confirm CWV targets.
Tooling note: QuickCreator supports AI-assisted drafting, multimedia embedding, and SEO-oriented checks you can combine with Google’s validation tools. Disclosure: QuickCreator is our product.

Measurement and governance

Search Console: Monitor Performance (image/video filters), Rich results reports (if applicable), and the Video Indexing report to see whether thumbnails and files are discoverable.
PageSpeed Insights and CrUX: Track CWV over time; prioritize media-heavy templates that drive the most traffic.
Social analytics: In YouTube Analytics, watch for search-driven views and measure the impact of captions and chapters.
Bing Webmaster Tools: Submit sitemaps, configure IndexNow, and review performance data.
Internal QA: Use checklists for alt text, captions, transcripts, structured data, and sitemaps; log changes and outcomes.
Optional: Tie improvements to a content quality framework for governance. See QuickCreator Content Quality Score for an example of how teams standardize reviews.

Looking ahead to 2026

Expect deeper multimodal grounding in AI-assisted search experiences. As systems increasingly combine images, video, and conversational context, the consistency and clarity of your media metadata will matter even more. Performance will stay central, especially INP responsiveness for interactive pages. Finally, social video will keep serving as both content and interface—so searchable short-form practices will remain vital.

Changelog

Added references to Google’s January 2024 multimodal update and Shorts–Lens experimental coverage.
Clarified CWV thresholds and the role of INP.

If you’re planning Q4 updates, prioritize a media-first audit: alt text and captions, VideoObject on watch pages, and CWV tuning for image/video-heavy templates. Then schedule quarterly validation. When you’re ready to streamline the process, consider using an AI-assisted editor that supports multimedia embedding and schema validation as part of your publishing workflow.
