Google just opened Search and Gemini to outside apps via MCP. The buried detail is in the help docs: Search may default to whatever app you used last for that task.
So the first app a customer links might be the last one Google ever offers them.

Google launched AI Mode ads in 10 more countries today. On the earnings call the same day, it said AI Mode growth hurt Search revenue "because of the lower monetization."
You can't opt out or see it separately. Filter your search terms for 7+ word queries and check that CPA.

Meta published three numbers for its new LLM ad ranking stack: 15.7%, 18.9% and 0.35%. All three compare Meta's new model to its old one, not your ads to no ads.
The part that changes your week: GenRecs describes ads by what's in them, so 10 near-identical variants probably count as one.

GA4 told one retailer its Google Ads ROAS fell from 8.07 to 4.79. Matched to real store orders, it actually rose from 4.42 to 7.93.
The culprit was a cookie banner plan that ran out of page views on Dec 1. Worth checking yours before Black Friday.

Lush grew revenue 9.4% after quitting social media ads. The catch: it barely bought social ads to begin with, and it spent four years doubling its email list to 6M.
Copy the inbox, not the exit.

ChatGPT ads only run on Free and Go. On Free, just 24.7% of requests are work-related, per OpenAI's new Signals data.
The people B2B marketers want are mostly on Plus, Pro and Enterprise. All ad-free.

A Delta ad in ChatGPT just clicked through Amazon's tracking server. ChatGPT inventory now has 4 buying routes (OpenAI, Criteo, StackAdapt, Amazon), and your teams may be on more than one without knowing it.

Google is now writing AI review summaries into Search ads in the US, UK, Australia and India. Positive only. You can't edit them, and there's no documented opt-out.
If your CTR jumps 10% while conversion rate drops, that's probably why. Go read your reviews this week, because they're your ad copy now.

Google just admitted Display Expansion on Search ran on a hidden 50% budget allocation. In February that goes away, and the new default for Display is High priority with no cap.
Google's fix is to set it to 50% yourself. Check your Display CPA first. For most accounts that number should be closer to 0-20%.

Google spent 5 years promising no ads based on Gmail, Drive or Photos. Since Oct 16 there's an exception for AI Mode users who connect those apps, and advertisers get no segment, no toggle, no report.
If your AI Mode numbers jump this month, don't credit your bid change yet.

McDonald's ran its biggest World Cup campaign ever in 110+ countries. Its CFO then put part of a Q2 traffic miss on it, and now the 32-year FIFA deal is done.
The tell was on the cups: the face of the campaign was Grimace, a character McDonald's already owns.

Before Aug 17, the median budget-limited Google Ads campaign beat its ROAS target by about 20%. Three weeks later: roughly zero.
The budget cap was quietly doing your bidding for you. Now the target is the only thing steering, and a lot of advertisers set it from memory.

OpenAI just admitted a ChatGPT ad can win the auction and still never show: a post-auction fit check can block it, and if ChatGPT finishes answering first, the ad gets dropped.
If your campaign is underdelivering, raising the bid fixes 1 of 7 stages.

From Oct 30, Meta's terms make you solely responsible for AI edits to your ads, including ones Meta turned on without asking. Its own liability is capped at $100 or your last 12 months of fees.
REI already learned this with a three-handled bike. Audit your Advantage+ settings before Black Friday.

Ahrefs says Google is feeding SEO tools fake results on 5% to 20% of searches, and it is quietly cleaning up past rank data.
If you sent a client a September report, export your history now. The numbers in the tool may not match it next month.

A year ago, Google showed an AI Overview on about 30% of "review" searches. Now it's 89%, per a Semrush panel of 400 commercial keywords.
The pages that were supposed to be safe from AI answers (reviews, "vs", "best X for Y") are now the most exposed. Small sample, but every cell went up.

Meta's creator-handle ads just hit a $15B run rate. One 65,000-ad dataset says they run 19% pricier CPMs than brand-handle ads, and still win on CPA.
With US price per ad up 23%, CPM is the wrong scoreboard for Q4.

Turned off Dynamic images in Google Ads years ago? From Dec 4 that switch stops covering new PMax campaigns.
Every new campaign will pull images straight off your landing pages, including whatever Black Friday banner is still up, unless you opt out campaign by campaign.

Salesforce is paying a 58% premium for Braze, but the deal can't close before February 2027.
That gap is the best negotiating window Braze customers will get for years. Price caps that survive a change of control, data export in writing, named features you can walk on if they're deprecated.

On Oct 30, ChatGPT Ads starts rewriting your headlines and can send clicks to a different page on your site. No review step. One toggle in Ads Manager turns it off, and if you run lead gen, I would flip it this week and test it properly.
