TL;DR
Google rankings wobbled all fortnight, with spikes on 20, 21, 24 and 27 October and still no confirmed update by 2 November. That is now two fortnights running with plenty of movement and nothing on the dashboard. The paid side was where the real change happened. Alphabet reported slowing paid click growth, ChatGPT Ads spread to 115 countries and switched on automatic creative changes by default, and Google removed the opt out from AI Mode ads in ten more countries.
Three jobs for this week: reconcile GA4 against real orders before the peak, check ChatGPT Ads settings before the automatic system rewrites live copy, and date any ranking drops from Search Console rather than the trackers, which are still noisy.
These two weeks were light on confirmed algorithm news and heavy on advertising change. What follows is the SEO, PPC and wider marketing news from 19 October to 2 November 2026, with the numbers and the actions that matter.
What To Actually Know
- Ranking volatility ran on, unconfirmed. SEOs logged spikes on 20, 21, 24 and 27 October. Google’s dashboard still shows nothing. The last confirmed event is the September spam update, which ended on 8 October, and the last core update was in May.
- Alphabet’s Q3 showed paid clicks slowing. Clicks rose 8% in the quarter, down from 11% across the first nine months. Cost per click rose 4%. Search revenue still grew 12% to $63.35 billion, so price did more of the work than volume.
- ChatGPT Ads scaled and handed creative to a machine. The platform reached 115 countries by 30 October. From that date a system that rewrites headlines, descriptions, images and destination URLs runs by default unless an advertiser turns it off.
- Google put more ads inside AI results. Ten more countries lost the opt out from AI Mode ads. Google also said AI search queries run three times longer than traditional ones, and one in six searches is now multimodal.
- Measurement is the quiet risk. One retailer found GA4 missed 66% of its holiday orders through setup faults. With rank trackers also unreliable, first party data needs a check before peak season.
1. Rankings stayed unsettled, with nothing confirmed
The movement from early October carried straight on. Search Engine Roundtable logged volatility on 20 and 21 October, again on 24 October, then a sharp spike on 27 October. Google confirmed none of it. The dashboard still lists the September spam update, finished on 8 October, as the most recent ranking event, and the last confirmed core update was back in May. The gap itself is the story. Rankings have now moved hard across two consecutive fortnights while Google has logged nothing at all.

Treat these as a rough signal, not a measurement. One commenter cited a Semrush reading of 9.4 on 27 October, while the tool makers themselves warn their data is noisy at the moment.
Two things made the picture harder to read. Publishers again reported weak Discover and News traffic, with one calling the news system broken after stale articles kept ranking. Rank tracking vendors also repeated that Google has been serving their bots altered results since late September, so third party position data deserves suspicion. That leaves Search Console as the one data source worth trusting right now.
“It feels like the rollout has started.”

2. Alphabet’s Q3 figures: paid clicks are slowing
Alphabet reported third quarter results on 28 October. The detail sits in the 10-Q. Paid clicks grew, but more slowly than earlier in the year, while cost per click kept rising. Search revenue held up well, and that combination points to where the growth came from.
| Metric (Google Search & other) | Q3 2026 | First nine months |
|---|---|---|
| Paid clicks growth | Up 8% | Up 11% |
| Cost per click growth | Up 4% | Up 4% |
| Search revenue | Up 12% to $63.35bn | Up about 16% |
Paid click growth, quarter versus the nine month run rate. The gap is the deceleration.
Here is the part that is easy to miss. Search revenue grew 12% while clicks grew only 8%. Price, not volume, carried most of the quarter. Cost per click held at plus 4% across both the quarter and the nine months, so advertisers paid steadily more for a pool of clicks that is expanding more slowly.
The contrast with Google’s own ad network sharpens the point. While Search grew, the network shrank on volume.
| Google Network, Q3 2026 | Change |
|---|---|
| Impressions | Down 14% |
| Cost per impression | Up 14% |
| Network revenue | Up 1.4% to $7.455bn |
For anyone buying Google inventory, the message reads the same on both lines. Volume is getting harder to come by, prices are drifting up, and more of the eyeballs now sit inside AI surfaces. Account efficiency will do more for results this quarter than chasing extra clicks.
3. Ads moved further into AI, on two fronts
ChatGPT Ads scaled, and turned on automatic changes
OpenAI moved fast. The platform reached 89 countries on 21 October, then added 26 more by 30 October to pass 115, and reported more than 100,000 advertisers. That is a 29% jump in country coverage inside nine days. Multi-image ads entered open beta on 26 October. The piece that needs attention is the creative enhancement system, on by default from 30 October, which can rewrite headlines, descriptions, images and destination URLs without sign off on each version.
ChatGPT Ads country reach, in nine days.
Watch the tracking. When the enhancement system changes a destination URL, there is no word yet on how UTM parameters survive. Check attribution before leaving it on, or the measurement gap that hit ChatGPT referrals earlier in October could happen again.
Google kept filling AI Mode with ads
Advertisers in ten more countries lost the option to opt out of AI Mode ads. On a 28 October podcast, Google’s Shivani Mohan repeated that AI search queries run three times longer than traditional ones, and that one in six searches is multimodal. Google also said ads in AI Mode and AI Overviews match against both the query and the content of the AI response, and pointed retailers to six optional conversational product fields in Merchant Center.
4. The rest of the paid search changes
Away from AI, Google and Microsoft both shipped practical changes to campaign controls.
| Platform | Change | What to do |
|---|---|---|
| Google Ads | High Value acquisition mode coming to Shopping. Re-engagement, Loyalty and Retention-only modes rolling into PMax, Search and Shopping. | Match each mode to a real customer goal before switching it on. |
| Google Ads | Seasonal conversion rate adjustments now work at ad group level for App campaigns, not just whole campaigns. | Keep these for short, known events like a sale, not as a routine lever. |
| Google Ads | Docs clarified that Smart Bidding Learning status lasts no more than 7 days, and which changes trigger it. | Do not stack bid strategy and goal changes in the same week. |
| Google Ads | Auto-apply of website coupons began reaching some campaigns. | Check the account for coupons applied without a manual decision. |
| Microsoft Ads | Max CPC removed from new standalone bidding campaigns, after the October start date. | Plan for automated bidding on new builds. Older campaigns keep the control for now. |
| Microsoft Ads | Advertisers can set up to 40 guidelines for AI-written ad copy. | Write the brand and claim rules in before letting the AI draft copy. |
5. SEO, social and measurement in brief
| Area | Story | Why it matters |
|---|---|---|
| SEO | Google expanded its spam guidance to cover sharing platforms and other UGC hosts. | Sites that host user content can be penalised for UGC spam. Moderate it. |
| SEO | Google’s Supersession-Decay Filtering, a freshness system, has run in Discover for two years. | Stale content gets filtered out. Refresh or retire aging pages. |
| Shopping | Google Universal Cart went live, letting shoppers save products across retailers. | Accurate Merchant Center feeds decide whether products appear. |
| Measurement | One retailer found GA4 missed 66% of holiday orders through setup faults. | Reconcile GA4 against real orders before the peak season. |
| AI search | Studies framed AI search as mainly a branding channel. 57.5% of consumers did not buy after AI advised against it. | Being named by AI tools now shapes demand, not only clicks. |
| Social | Pinterest inventory opened to programmatic buying via Yahoo, Amazon and DV360. TikTok pushed premium holiday placements. | More ways to buy social reach before the Q4 peak. |
| Ecommerce | An eMarketer study found 47% of US digital shoppers have not used retail chatbots and are not interested, up from 38.2%. | Chatbot interest is cooling. Do not over-invest on hype alone. |
Put the last two rows side by side and a useful tension appears. Shoppers say they avoid retail chatbots, with disinterest rising from 38.2% to 47%, yet AI advice still changed what 57.5% of them bought. The influence is happening upstream of the chatbot box people say they dislike, inside the AI answers they read without thinking of it as a chatbot at all. Visibility in those answers matters even where the click never lands.
What To Actually Do
A short list for the next week, in rough priority order.
- Audit GA4 before the peak. Reconcile recorded purchases against real store orders. Check the cookie banner, look for double counting, and filter bot traffic. A 66% gap wipes out a quarter of data.
- Review ChatGPT Ads settings now. Decide whether to allow automatic creative changes. If destination URLs can be rewritten, confirm UTM tracking still holds before leaving the feature on.
- Date ranking moves from Search Console, not trackers. With the tools serving noisy data, compare affected pages and queries inside Search Console and ignore third party positions on their own.
- Plan for automated bidding on Microsoft Ads. New standalone campaigns no longer take a Max CPC. Set targets and guardrails instead of a manual cap.
- Refresh or retire stale content. With freshness filtering confirmed in Discover and weak news visibility, update the aging pages that still earn their place and prune the rest.
- Track whether AI tools name the brand. A recommendation inside an AI answer now moves demand even when no click follows, so measure mentions, not only sessions.
- Tighten Merchant Center feeds. Universal Cart and the conversational product fields both reward clean, complete data. Fix the feed before chasing new placements.
The split this fortnight was clean. The organic side stayed noisy and unconfirmed, while the paid side moved fast into AI and let automation take over more of the day to day work.
