Google Delays: What Business Owners Need to Know About Gemini 3.5 Pro
Google’s Gemini 3.5 Pro launch has been postponed, leaving AI‑driven leads mis‑tagged as “Direct/Other” and forcing local businesses to rethink attribution. By tapping the newer Flash and multimodal Gemini models, diversifying across AI providers, and tightening schema and tracking, businesses can keep their AI search visibility strong despite the delay.
Key Highlights
- ✓Google’s Gemini 3.5 Pro launch delayed, impacting AI traffic attribution.
- ✓Flash and multimodal Gemini models are now available for immediate use.
- ✓AI calls still hide in “Direct/Other,” requiring manual re‑classification.
- ✓Local businesses can leverage alternative AI platforms to stay competitive.
What Happened
In early 2026, Google unveiled Gemini 3.5 Pro, promising a major upgrade in conversational AI and coding performance. The model was expected to outpace rivals such as Claude Opus 4.6, but by mid‑July Bloomberg reported that internal tests fell short of Google’s cost‑efficiency and speed targets, prompting a public postponement. Since then, Google has rolled out a suite of Gemini variants—including 3.7 Flash, 3.8 Flash, and specialized speech, video, music, and robotics models—while the flagship 3.5 Pro remains absent from the September 22 API changelog.
Key Details
- Initial promise: Gemini 3.5 Pro was slated for a June launch following a May I/O announcement.
- Delay reason: Coding performance failed to meet Google’s efficiency and latency goals; a tweak to the training data did not close the gap.
- Current status: The September 22 API changelog lists only Flash and multimodal models; 3.5 Pro is still missing.
- Competitive landscape: Gemini 3.1 Pro topped the Artificial Analysis Intelligence Index, but the delayed flagship has allowed competitors like Claude Opus 4.6 to lead on several AI‑search metrics.
- Impact on attribution: AI‑driven calls continue to collapse into the “Direct/Other” bucket, a problem highlighted in Search Engine Journal’s checklist.
What It Means For Your Business
1. AI Search Attribution Remains a Wild Card
With Gemini 3.5 Pro unavailable, AI‑generated traffic is still being logged as “Direct/Other,” which can mask the true contribution of AI leads. Applying the downloadable SEJ checklist lets you re‑classify those calls, giving a more accurate ROI picture.
2. Leverage Flash and Multimodal Models
Google’s Gemini 3.7 and 3.8 Flash models deliver faster, cheaper inference. Integrating these APIs lets local services deploy chatbots that answer FAQs, schedule appointments, and provide instant support—boosting conversion without waiting for the flagship.
3. Don’t Put All Your Eggs in Google’s Basket
The delay underscores the volatility of any single AI ecosystem. Complement Google’s tools with stable alternatives such as OpenAI’s GPT‑4o or Anthropic’s Claude 3, both of which offer mature APIs and strong developer communities.
4. Optimize the “Direct/Other” Funnel
Even without the 3.5 Pro, AI assistants still route users to your site. Strengthen schema markup, local citations, and structured data to signal relevance to AI engines, increasing the odds of appearing in AI‑generated answers.
5. Stay Ready for Future Releases
Google has pledged to ship “many models quickly,” suggesting a new Gemini 3.5 Pro—or a comparable offering—could arrive soon. Keep API keys current, monitor the changelog, and be prepared to pivot your integration strategy when the model finally launches.
Bottom Line
The Gemini 3.5 Pro postponement highlights the unpredictable nature of AI innovation. For local businesses, agility is essential: track AI traffic precisely, adopt the available Flash and multimodal models, diversify your AI stack, and fine‑tune your content for AI discovery. These steps will help you remain visible as the AI search landscape continues to evolve.

FAQs
- How can I reclassify AI‑driven calls that appear in the “Direct/Other” bucket?
Use SEJ’s AI Search Tracking Checklist to create custom attribution rules in your analytics platform, mapping AI‑specific keywords or referral sources to a dedicated channel.
- Will the Gemini 3.5 Pro eventually be released, and how will it affect local SEO?
Google has signaled that it will ship many models quickly; when 3.5 Pro arrives, it should improve conversational search relevance, but businesses should prepare for a phased rollout and test performance before fully relying on it.
- Are there other AI platforms I can use while waiting for Google’s model?
Yes. OpenAI’s GPT‑4o, Anthropic’s Claude 3, and Meta’s LLaMA 2 all provide stable APIs and active community support for building chatbots, content generators, and voice assistants.
Why This Matters For Your Business
The postponement of Gemini 3.5 Pro means a sizable slice of AI‑driven traffic is currently hidden in the generic “Direct/Other” category of analytics dashboards. For local businesses, this obscures the true value of AI‑generated leads and can lead to under‑investment in AI‑focused marketing. By re‑classifying those calls with the SEJ checklist, owners gain a clearer view of ROI and can allocate budgets more effectively. At the same time, the rapid rollout of Gemini 3.7 and 3.8 Flash, along with multimodal variants, offers a practical stopgap. These models deliver lower latency and cost, enabling businesses to launch AI chatbots, voice assistants, and content generators without waiting for the flagship. Diversifying across providers such as OpenAI, Anthropic, or Meta further insulates companies from platform delays and sustains AI visibility in search results. In short, precise attribution and a flexible AI strategy are the best defenses against the volatility of any single AI platform.
