18 Updates - Smart Bidding Cap, TikTok Shop Plus

Happy Friday.

Rain, a muddy dog and a race to the couch before anyone grabs a towel. If that sounds like your house today, you already know how a good funnel feels.
Google just capped Smart Bidding's learning phase at 7 days, TikTok Shop launched a paid membership, and ChatGPT's sources are shifting fast.
Also today: Reddit's traffic is falling while its users keep growing, LinkedIn took B2B ads to British TVs, and audio ads work best before the show even starts.

Here is everything I am covering today.

Google Caps Smart Bidding Learning at 7 Days and Gives You More Ways to Check Its Work

Bill Murray spent Groundhog Day stuck in a loop, and so did Smart Bidding. One big budget change and your bid strategy went straight back to "Learning" while Google recalibrated.

Google just broke that loop, and it also handed you a few new ways to check the platform's work.

Google broke the loop. The "Learning" label, which appears while a bid strategy recalibrates, now lasts 7 days at most. Budget, bid target, creative and targeting changes no longer trigger it at all.

That means your Black Friday and Cyber Monday budget bump will not set it off. I still want you to watch performance closely, because performance can still wobble even when the label stays away.

Receipts, please. A new Invalid Traffic Overview card estimates what Google saved you by filtering out bots and accidental clicks before billing. It also shows credits for invalid traffic Google caught after billing, plus daily and campaign breakdowns. It is rolling out globally this week.

Those credits will not change Cost or CPA in your Campaigns table. The "Invalid Activity Credit: Search & PMax" report in Report editor shows the adjusted numbers, so that is where I would check them.

AI Max comes pre-installed. The setting that lets Google show your ads on searches beyond your keywords is on by default for new Search campaigns in Google Ads Editor 2.14. Automated ad text and landing page picks are on too.

Check your settings before you publish anything new. My recommendation is to treat every new campaign like it has AI Max switched on, because now it does.

At least you can track it. A new ValueTrack parameter, a URL tag Google fills in on each click, marks AI Max expansion clicks with an "a". Add {search_term_matchtype} to your tracking template and you can compare those clicks with your keyword traffic.

I think this is the most useful of the batch. You cannot manage what you cannot measure, and AI Max expansion was a black box until now.

Your tracking gets a report card. Google just documented Data Strength Uplift, a metric that estimates how much first-party data tools like enhanced conversions add to your reported conversions.

Where: Goals > Conversions > Summary
Minimum: 100 website or 20 offline conversions in 14 days
Catch: it shows better tracking, not more sales

Do not mistake a higher uplift score for more revenue. It tells you your measurement got stronger, which is still worth knowing before you judge a campaign.

My take: no more waking up in "Learning" after a budget change is a genuine quality-of-life win for anyone running seasonal campaigns. The 7-day cap plus the invalid traffic card and the AI Max tracking tag give you a clearer picture of what Google is actually doing with your money. Use that picture.

TikTok Shop Pitches a Membership as LinkedIn Takes B2B Targeting to British TVs

Get in, loser. TikTok Shop just priced the ride, Reddit is shrinking and growing at the same time, and LinkedIn decided your next B2B lead is sitting on the couch.

Prime has a cheaper cousin. TikTok Shop is piloting TikTok Shop Plus, a paid membership, with over 1 million top US shoppers. After a 30-day free trial, it is $9.99 a month, which is $5 less than Prime.

Members get:

Free shipping on "Plus"-badged items
An extra 10% off select products
Three monthly coupons, up to $30 off
Extra Black Friday deals

If you sell there, check which of your listings carry the badge. That badge is about to become a buying signal for TikTok's most active shoppers.

Reddit is shrinking and growing at once. Similarweb estimates Reddit's global visits fell 13% year over year in October. Reddit counts weekly users up 16%, a Q3 average of people, not visits, so the two numbers measure different things.

Reddit partly blames Google's AI Overviews and AI Mode for over 1 million fewer search referrals a week. I think that is the number to watch, because it shows how much AI search is already reshaping where traffic comes from.

And your next lead is on the couch. LinkedIn's CTV Ads, which put your video ads on streaming TV, just launched in the UK. You can target viewers by job role, industry and seniority across LG, Paramount+, Titan OS and more.

It looks like business people do rest in front of the TV, just like normal people. If your B2B buyer watches streaming TV in the evening, your ad can now meet them there.

LinkedIn will also label lurkers. LinkedIn is testing a "Frequent Viewer" label that flags repeat visitors to your profile. Only some users see it for now.

I think this is a warm-lead signal worth watching, right up until your name shows up on a prospect's list and the roles reverse.

Comparison shopping moves into the chat. Pinterest's AI assistant now has a Compare tool that lines up similar products by price, availability and reviews. CEO Bill Ready said about 80% of assistant searches are commercial, so shoppers will compare your products right there in the chat.

Convenient timing with Black Friday around the corner. If your product pages are thin on price and availability details, fix that before shoppers start comparing.

My take: TikTok Shop Plus is the headline for sellers, because a membership turns casual scrollers into committed shoppers with a badge to look for. LinkedIn's TV move is the one I would test first for B2B, though, since job-role targeting on a living-room screen is a combination I have not seen before.

Where ChatGPT Gets Its Facts, and How Your Brand Gets In

ChatGPT is that friend who has never met you but has heard a lot about you. Ahrefs tracked where the hearsay comes from, and besides yourself, meaning stuff you feed it with like files, questions and data, there are three more sources that can put you at the top.

Let me go through them one by one.

1) Training data. Unless you block GPTBot, OpenAI's training crawler, your public pages likely feed future models. Today's models know nothing after spring 2026, so anything you launched since then needs a search to be found.

Here is the twist. On October 31, AI search tracker Goodie saw the share of ChatGPT answers with no sources jump from 1.5% to 12.2%. Its best guess is that ChatGPT now searches less, and those answers come straight from training. Think twice before blocking GPTBot, because training data may be doing more of the talking than it used to.

2) Web search. Of the searches ChatGPT runs, 6.8% use site: to search one website, and three in four of those hit brand sites. For brand questions, 83% of answers cited the brand's own site, and 70% cited it first.

So spell out your prices, specs, policies and support answers in plain text on your own site. And let in OAI-SearchBot, OpenAI's search crawler, or ChatGPT cannot cite you at all.

Here is a bonus take. OpenAI now offers a peek through its Business Hub, which lets you claim your business, update details and product feeds, and see your ChatGPT mentions, clicks and the themes of chats citing your site. OpenAI says claiming should not change how often you appear, but it keeps your facts current, and current facts are what get cited correctly.

3) Publishers. Those with OpenAI content deals earned 12.5% of citations among ChatGPT's 200 most-cited domains in late September, up from 7.5% in March. And when Ahrefs tested self-promotion, 94% of its new mentions came from answers citing someone else's page.

Find the reviews, "best X" lists, forums and publications ChatGPT cites for your category, then aim for more than a passing mention in them. Third-party pages are doing most of the talking about you.

My take: ChatGPT will keep hearing about you secondhand, so make sure every version of your story checks out. Keep GPTBot and OAI-SearchBot welcome, keep your own site's facts in plain text, and earn mentions on the pages ChatGPT already trusts.

DATA STORIES

Listeners Remember Audio Ads at the Start and Middle

In audio, timing is everything. Comscore asked people who stream audio which ads they remember hearing in the past month, and the ads at the end left the weakest impression.

Ads before the content starts lead at 49%, with mid-content ads right behind at 47%. Ads at the end fall to 27%, roughly half the recall of the other two spots. A quarter of listeners do not remember hearing any audio ads at all.

Recall depends partly on how often each slot runs, too. Publishers sell fewer end-of-content ads, so lower recall does not mean those ads are useless. But listeners still remember them far less.

My take: listeners are paying attention when the show starts and while it plays. Once it ends, many skip ahead, close the app or move on to the next thing before the ad finishes. Put your budget into pre-roll and mid-roll slots, and save end-of-content ads for cheap reminders. Mention your brand name in the first few seconds, so listeners who skip still hear it.

QUICK UPDATES

Google: Your AI search reports just got a second asterisk. Gemini 4 Hydrogen, Google's new fast model, is now the default in AI Mode for all users worldwide and handles the hardest AI Overview questions. Google promises more links but shares no numbers.

ChatGPT Ads: Bid ceilings are about to become averages. OpenAI's Max Bid and Max CPC caps retire on January 1. From November 18, API tools using them to create campaigns or switch bid types get average-cost targets, so single clicks can cost you more.

EU: Influencer skipped the ad label? Under the EU's proposed Digital Fairness Act, a consumer law covering anyone selling to EU shoppers, brands and agencies would share the blame. It would also ban dark patterns like fake low-stock claims and require an off switch for addictive features. Still, you have got years before it is law.

Microsoft Ads: Running AI-made images or video in the EU or New York State? Microsoft Advertising now stamps a "Made with AI" watermark on those ads, if you label the asset "AI Content + Watermark." Google Ads and Pinterest imports that carry an AI flag get that label automatically, so check them after each import.
