Picture a headline your compliance officer never saw: "Guaranteed Retirement Income." Nobody at the firm wrote it. Google did, assembled from words on your website, and it ran in front of a 63-year-old searching for a retirement planner.
That's the risk AI Max brings to an advisory account, and it's why AI Max comes last in this guide. It can find searches your keyword list missed and write headlines you didn't think of. It can also write headlines a registered adviser is not allowed to run, and send prospects to pages nobody approved as ad destinations.
Four things follow: the pieces bundled inside AI Max, the reason it waits for a mature account, a quiet conflict that can strip out Chapter 8's pinned compliance line, and the rulebook Google offers for words and claims it must never write for you.
AI Max Is Broad Match With Its Own Copywriter, and Neither Has Met Your Compliance Officer
AI Max isn't a separate campaign. It's a bundle of three features Google adds to a Search campaign.
Piece one widens the net: ads become eligible for searches your keyword list never named, much like broad match. Piece two, which Google calls text customization, drafts fresh headlines and descriptions on the firm's behalf. Its raw material, per Google, is the firm's website, landing pages, current ads and keywords. Piece three, Final URL expansion, lets Google override the landing page the firm picked and route the visitor to another page on the domain.
For a shoe store, those are mostly upside. For an advisory firm, every one of them touches a compliance question. Looser matching can put an ad in front of searches the firm would never bid on. Google-written headlines are advertisements nobody at the firm reviewed. And a Google-chosen landing page can be a blog post or a client stories page that was never cleared as an ad destination, the same problem Chapter 10 covered for Performance Max.
Google turns AI Max on by default in new Search campaigns, which is why Chapter 9 switched it off at build.
Every AI Max Feature Feeds on Conversion Data a Young Advisory Account Hasn't Built
AI Max also needs fuel a new account doesn't have. Google's setup page says all three pieces depend on automated bidding that aims at conversions to work properly. In plain terms, AI Max needs Google bidding toward conversions, with enough conversion history to know what a good client looks like.
That rules out Isolation for good. Isolation is the exact-match campaign this guide built first, bid by hand, and its whole purpose is control over which searches it buys. AI Max would undo that purpose.
It also puts AI Max at the end of the line. Recall the sequence: hand-bid exact match came first; the broad-match scout followed at roughly 30 quality conversions a month; Performance Max and Demand Gen used the same 30-conversion gate, each waiting for the campaign before it to settle. AI Max comes after all of that, and only on Exploration, the broad-match campaign that already bids toward conversions. Run it as a controlled test with a fixed end date, and compare cost per signed client, not clicks.
A fair test gives AI Max enough time and budget to learn. We give it at least a month, in line with the month or two Chapter 7 said Exploration needs to train, and change nothing else in the campaign while it runs. If the bids, budget and ads all change at the same time, nobody can say what AI Max did. At the end, look at three numbers from the signed-client tracking in Chapter 1: how many new searches AI Max found, how many of those searches booked meetings, and what each signed client cost compared with the same campaign before the test. If AI Max found volume but the cost per signed client rose, it found the wrong people.
Final URL Expansion Tells Google to Ignore the Disclaimer You Pinned
Here's the setting conflict most advisors won't see coming. Chapter 8 explained that a line your compliance officer requires in every ad has to be pinned to Headline 1, Headline 2 or Description 1, because that's the only way Google guarantees it shows.
AI Max breaks that guarantee. Google's own page on how AI Max works says: "If you've turned on the Final URL expansion setting, pinning of RSA assets will not be respected." It says the same about URL inclusions: "pinned assets won't be used if a more relevant URL is chosen."
So a firm can do everything right in Chapter 8, pin its disclosure line, then turn on AI Max with Final URL expansion and lose the pin without any warning in the ad itself. Ads start running without the line the compliance officer required.
The fix is simple to state, though it takes discipline to keep. Wherever a pinned line matters, both switches stay off: Final URL expansion and URL inclusions. Google's own setup page names that pair as the condition for pins to hold. If the firm wants to test AI Max's matching or text features, test them with Final URL expansion off, and confirm in the ads preview that the pinned line still appears. Check again whenever someone changes the campaign settings, because Final URL expansion is one checkbox, and the person who turns it on may not know a compliance line depends on it staying off.
Text Guidelines Can Ban "Guaranteed." Banning the Dollar Sign Won't Stop a Price.
If a firm does turn on text customization, text guidelines are how it tells Google what not to write. Google still labels them a beta, and they come in two kinds.
The first kind, term exclusions, is a blocklist: a firm enters up to 25 words or phrases per campaign, and Google keeps them out of the copy it generates. Messaging restrictions are plain-language rules about concepts, claims or tone, and each campaign gets up to 40. Both apply to assets Google already created: generated headlines that break a new guideline stop serving.
Two details matter for advisors. Term exclusions are language-specific, so excluding "guaranteed" in English won't block it in a Spanish-language ad; messaging restrictions, by contrast, apply across languages. Prices slip past the blocklist entirely. Google's example is that putting "$" on it doesn't stop a priced headline, so a line like "Planning From $175" could still appear. Its fix is a messaging restriction worded as "Don't generate assets with prices." It also advises adding an example to each restriction, so the rule is concrete.
Write each restriction as a hard rule, one idea at a time. Google's own guidance says the model "can only take hard requirements," so "if possible, avoid mentioning returns" won't work the way "never promise returns" will. Google also warns that inefficient or contradictory guidelines can remove a large number of good assets, so a long list written in a hurry can hurt performance without making the ads any safer. Start with the handful of rules compliance cares about most, and add to them as the reviews in the next section turn up problems.
Google's own ad policy already points the same way. Its rules on unreliable claims bar "guaranteeing returns, or promising returns that are unrealistic or exaggerated." A text guideline doesn't replace that rule; it makes it far less likely Google's own copywriter breaks it on your account.
A starting list for an advisory firm might look like this, with the final version set by the compliance officer:
- Term exclusions: guaranteed, risk-free, no fees, best, top-rated, and any claim that isn't true for your firm, such as fiduciary, fee-only or free consultation.
- Messaging restrictions: "Never promise or imply guaranteed returns, e.g., guaranteed 7% income." "Don't generate assets with prices, e.g., $175 an hour or 1% a year." "Never quote investment performance, e.g., beat the market by 4%." "Never name other advisory firms, e.g., Edward Jones."
Text Guidelines Shrink the Risk. Compliance Still Reads Every Headline Google Writes.
Text guidelines lower the odds of a bad headline. They don't make the headlines Google writes any less the firm's advertisements. The SEC treats ads shown to many people as advertisements under its Marketing Rule, and nothing in the rule exempts a headline because Google wrote it.
So build a review habit. Google says the search terms report now shows "AI Max" as its own match type, with a view that combines the search, the headline and the landing page for each click. Its asset report shows the headlines AI Max generated, and Google says you can remove any of them. Have the compliance officer read the generated headlines on a set schedule, weekly while AI Max is new, and remove anything that wouldn't have been approved if a person had written it.
Keep a copy of what ran. Generated headlines change, and an ad that ran for two weeks in March may be gone from the account by summer. Chapter 14 covers how long a registered adviser has to keep advertisements and why Google's interface isn't the archive.
Next: Every Google Ad an SEC-Registered Adviser Runs Is an Advertisement. Keep It Five Years.
The campaigns are complete. The bonus chapters start with Chapter 14, on the SEC's Marketing Rule and Google Ads: what makes a search ad an advertisement under the rule, what it can and can't say, and the five-year record keeping requirement that applies to Google ads too, which the SEC has cited firms for missing.
All chapters are on the guide's home page.
For advisory firms on our Google Ads management service, AI Max waits for a proven record of signed clients. When it finally goes on, the text guidelines go in first and the compliance officer gets a weekly list of every headline Google wrote. If your account turned on AI Max by default, check whether your pinned disclosure is still showing.
