Week in Brief
- Google extended the Dynamic Search Ads sunset from September 2026 to February 2027 and will reopen DSA campaign creation on 15 June, confirmed by Google Ads Liaison Ginny Marvin on 12 June.
- Similarweb’s June update, posted on LinkedIn on 11 June, put ChatGPT at 52.7% of worldwide AI-platform web traffic, with Gemini second at 27.3% and Claude at 8.9%.
- Google Ads API v20 stopped working on 10 June, breaking older scripts and third-party tools still running on the retired version.
- Search Engine Roundtable reported Google rolled out preferred sources globally and shipped link improvements inside AI Mode and AI Overviews.
Google extends Dynamic Search Ads sunset to February 2027
Google Ads Liaison Ginny Marvin confirmed the change on 12 June, on LinkedIn. The automatic upgrade of Dynamic Search Ads to AI Max moves from September 2026 to February 2027. Google will also reopen DSA campaign creation from 15 June, reversing an earlier phase-out. Marvin said the extension responds to advertiser feedback asking for more transition time. Automatically created assets and campaign-level broad match settings still move to AI Max in September 2026.
What this DSA Extension means for B2B, ITES and SaaS
B2B and lead-gen advertisers running non-e-commerce DSA campaigns get the most relief here. Service, SaaS, and ITES accounts that lean on DSA now have until February 2027 to test AI Max side by side. PPC.land notes the migration is hardest for accounts where DSA is more than half the search mix and transition from one to another in a shorter period is not an option.
Action Plan for this Transition
Create an AI Max test campaign and run it alongside your top-performing DSA campaign for 30 days. Compare the cost per qualified lead, lead quality, and overall conversion efficiency. Based on our experience, AI Max tends to perform particularly well for local businesses because it is more intent-aware, leveraging existing ad performance and website content to dynamically tailor messaging and assets to match specific user queries. This often results in more relevant ad experiences and higher-quality leads.
The White Bunnie team has primarily seen success with AI Max in local service-based businesses. We have not yet completed a sufficient performance assessment for B2B, ITES, and SaaS organizations, so results in those industries should be evaluated carefully through testing before broader adoption.
Similarweb June data shows ChatGPT at 52.7% of AI-platform web traffic as Gemini climbs to 27.3%
Similarweb posted its June generative-AI traffic update on LinkedIn, covering worldwide web traffic through 26 May. ChatGPT held 52.7%, with Gemini second at 27.3% and Claude at 8.9%, across seven named platforms. Gemini was the fastest-growing large assistant in the set. The figures measure web visits only, so app and API usage are excluded.
The generative AI search landscape is becoming increasingly fragmented, creating new opportunities and challenges for SEO teams. While ChatGPT continues to lead with 52.7% of AI website traffic share, its dominance has declined significantly from 76.4% just 12 months ago. At the same time, Gemini has more than tripled its share, growing from 8.9% to 27.3%, while Claude has emerged as a strong contender, rising from 1.6% to 8.9%. This shift reinforces that brands can no longer optimize solely for a single AI platform.
What this revision of traffic share means for B2B and SaaS
As AI assistants increasingly influence discovery, SEO strategies must focus on building entity authority, structured data, topical depth, and consistent brand mentions across the web to improve visibility across multiple AI ecosystems. The future of search is no longer about ranking in one engine, it is about being the most trusted source cited by many.
B2B and SaaS teams that built their GEO strategy around ChatGPT citations alone are now under-covering a quarter of AI search traffic. Gemini at 27.3% means Google AI surfaces, not just ChatGPT, decide whether your category answers name you. If you track AI citations, add Gemini and Google AI Mode to your monitoring rather than reporting ChatGPT visibility alone.
Google Ads API v20 stopped working on 10 June, breaking older scripts and third-party tools
Google Ads API v20 shut down on 10 June. Any script, connector, or third-party tool still calling v20 stopped returning data once the version retired.
Advertisers running automated bidding scripts or custom reporting on the old version saw those breaks. Google had told advertisers to upgrade before the cutoff.
Bidding and budget automation: Custom bid scripts, rule-based budget pacing, and third-party bid-management platforms that talk to the API stop pushing changes. Campaigns keep running on whatever their last instruction was, which means bids can drift, budgets can over- or under-spend, and nothing self-corrects.
Conversion data flowing back to Google: CRM and offline conversion uploads (e.g., a lead that closes into a sale days later) stop reaching Google Ads. This is doubly damaging; you lose reporting accuracy and you starve Smart Bidding of the signal it uses to optimize, so performance degrades even on campaigns that are otherwise untouched.
Reporting and dashboards: Looker dashboards, CRM conversion uploads, and Merchant Center feeds break in the same hour. Anything pulling cost, click, or conversion data via v20 returns blanks or errors, leaving gaps in dashboards and any downstream reports executives rely on.
There’s a related deadline worth flagging since they cluster in the same week: on June 15, 2026, Google updates Consent Mode so the ad_storage parameter becomes the only control governing advertising data sent from GA4 to linked Google Ads accounts, with Google Signals limited to Analytics-only purposes. Different mechanism, but it lands in the same window and also touches ad data flow and measurement accuracy.
What this means for B2B and SaaS: B2B advertisers who rely on agency scripts or custom reporting dashboards are exposed here, not those using the standard interface. If your team automates bid adjustments, budget pacing, or pipeline reporting through the API, a silent failure could be skewing your data right now. Confirm with whoever maintains your tooling that everything moved to a supported API version.
On White Bunnie Radar for Next Week
- Google’s wider AI Mode and generative-UI rollout, announced at Google I/O 2026 and covered by TechCrunch, continues this summer and will keep changing how links appear in AI answers.
- Google’s roll-out of first party AI data as on June 3, 2026 via the Google Search Central Blog that dedicated Search Generative AI performance reports are now available in Search Console.
White Bunnie Observation
Across the ITES and SaaS accounts where we run search, we’re seeing real turbulence in organic rankings since the May 2026 core update finished rolling out on 2 June, even though the volatility trackers called the week normal.
This is the core update still settling, not a new signal to chase. We’re holding content rewrites or any major SEO action on the accounts until rankings stabilise for 7 days, then re-auditing the specific pages that dropped. One of our accounts, a US-based local-business client, we manage has seen running against the trend. Account has shown 3x growth in organic traffic since the core update.
