AI Tools for Google Ads [with next level features]

Google Ads already runs on AI. Most of the “AI tools for Google Ads” you’ll find sit on top of Google’s own machine, so the part you control is what that machine gets to decide.

On 30 August 2026 I pulled the settings of 84 live Performance Max campaigns across 42 accounts. 45 of them had no target ROAS or target CPA at all - Google’s AI was spending with no number to hit.

So this guide starts with what Google’s AI does on its own, then the six tools I’d add on top, with every price checked on 30 September 2026.

The short version

Can AI run Google Ads on its own?

It already does most of the running. Bidding, search matching and placement are Google’s AI on nearly every account I open.

The problem is what it’s told to chase. When I read 100 accounts in August 2026, the median account had 9 primary conversion actions, and Smart Bidding bids toward all of them. A newsletter signup can count the same as a sale.

On my wife’s travel planning account, a lead means a completed multi-step enquiry form. They cost about $7 and 1 in 6 becomes a customer, so a customer costs about $42. That’s the number I want the bidding to see.

So before any tool, fix the conversion actions. Every AI in this list, Google’s included, is only as good as the goal you hand it.

What Google’s own AI does

Most of the chatter about AI for Google Ads is about ChatGPT, Claude and new software. But a lot of the real AI work is already going on inside the Google Ads platform, and has been for years.

AI Max for Search

AI Max is a campaign setting. It matches searches past your keywords, rewrites your ad text and can send people to a different page on your site ( Google’s feature list ). In April 2026 Google added AI Brief controls so you can tell it more about the business.

The bit most advertisers miss: it is switching itself on. Google says campaigns using automatically created assets or campaign-level broad match start upgrading to AI Max from September 2026, and Dynamic Search Ads follow from February 2027 ( Google’s upgrade post ).

Final URL expansion is the setting I’d watch. In the PMax campaigns I pulled, 42 of 84 had served at least one page the advertiser never picked - blog posts and policy pages. AI Max has the same switch, so set your URL exclusions before the upgrade reaches your account. My full take is in the AI Max guide .

Performance Max

Performance Max runs one campaign across all of Google’s inventory. It can work well with good conversion values and audience signals, but it reports on itself.

34 of the 84 campaigns I pulled still targeted people by presence or interest, which is the default and reaches people who only show interest in your location. 41 had no edits in 28 days. I wrote up the seven checks I run in the Performance Max audit .

Smart Bidding

Smart Bidding sets a bid for every auction, using signals like device, location and time of day. It’s the part of Google’s AI I trust most - once the conversion actions are right. With 9 primary actions it optimises for the average of nine different things.

Ads inside AI Overviews and AI Mode

Search, Shopping and PMax ads can already show inside AI Overviews, in English, in 12 countries including the US, Canada, Australia and India. The UK isn’t on the list. You can’t opt out and you can’t target the placement ( Google’s help page ).

In AI Mode, Google said in May 2026 it is “testing two new types of ads” . There’s nothing separate to buy yet. Your ads get there through the campaigns you already run.

Check what AI Max is doing in your account

Two queries tell you whether AI Max is on and how much of your spend comes from searches you never added as keywords. Run them through the Google Ads API , or paste them into Claude once it’s connected (next section).

SELECT campaign.name, campaign.ai_max_setting.enable_ai_max,
  campaign.bidding_strategy_type, metrics.cost_micros, metrics.conversions
FROM campaign
WHERE campaign.advertising_channel_type = 'SEARCH'
  AND campaign.status = 'ENABLED'
  AND segments.date DURING LAST_30_DAYS
ORDER BY metrics.cost_micros DESC

SELECT segments.search_term_match_source, metrics.clicks,
  metrics.cost_micros, metrics.conversions
FROM search_term_view
WHERE segments.date DURING LAST_30_DAYS

Query 2 returns one row per match source. Here’s how to read them:

If the AI Max rows spend a lot with few conversions, the next step is the search term review , and that’s where the wasted spend usually sits.

Connect Claude or ChatGPT to your account

Google publishes an official MCP server for Google Ads . MCP is the plug that lets an AI assistant call a tool. This one has three tools - search, get_resource_metadata and list_accessible_customers - and all three only read. None of them changes a bid, a keyword or a budget. Since Google retired developer tokens on 9 September 2026, you need a Google Cloud project with Explorer access and a Google login to set it up.

I personally prefer using Claude over ChatGPT. There are two routes:

1. Claude Desktop. The Google Ads MCP guide walks through it for free.
2. Claude Code. The Claude Code setup walkthrough covers the install, the Google Cloud access and one kickoff prompt that makes Claude do the technical setup. You don’t need to know what a terminal is, which was rather the point of writing it.

It’s great for questions you’d otherwise need GAQL for: “which search terms spent over $100 with no conversion last month?” Meta’s server works differently, because it can make changes. The differences are laid out in Google vs Meta ads MCP .

ChatGPT can do the same job. My ChatGPT connection guide shows the setup. One of the smartest uses I’ve seen is asking it to write a custom Google Ads script from what it reads in the account.

Third-party tools worth paying for

Google’s AI spends the money. These tools check its work and save you the grunt work around it.

Opteo

Opteo doesn’t lead with “AI”, but it watches the account and turns what it finds into specific fixes you approve one at a time. I love their human-centric client reporting system - reports a client can actually read.

Pricing on 30 September 2026: Basic $129 a month (10 accounts, $25,000 of spend), Professional $249 (25 accounts, $100,000), Agency $499 (75 accounts, $250,000), and Enterprise on request.

Optmyzr

Optmyzr is the rule-and-script engine for people who manage lots of accounts. Every plan includes the AI Sidekick and MCP access for Claude and ChatGPT. The plans are Essentials, Premium and Enterprise, priced by the ad spend you manage, and the page shows no numbers. There’s a 14-day trial with no card.

Adalysis

Adalysis is strongest on ad testing and audits: 100+ audit checks, tools for AI Max and PMax, and unlimited accounts. The price sits behind a spend slider, and trials run 30, 45 or 60 days.

Where PPC.io fits

Every tool above works inside the ad account. None of them looks at the page the ad sends people to, and that’s often where the money goes.

Postclick is our tool for that page. It audits your landing page, designs new versions and builds the one you pick. It does not connect to your Google Ads account. You start with 56 free credits and an audit costs 18, then plans are $9, $29 or $99 a month.

If you’d rather someone ran the account for you, we manage Google Ads for $2,000 a month flat , and the audit is free on read-only access. The account agents on /agents are still a waitlist.

Does Google allow AI-generated ads?

Yes. AI-written ads follow the same policies as any other ad. From July 2026 Google has an AI label setting for ads shown in the EU, India and New York, and it may label assets made with its own AI tools itself ( Google’s policy page ).

FAQs

What is Google Ads AI?

The machine learning inside Google Ads that decides bids, matches searches to your ads and picks placements. The main parts are Smart Bidding, AI Max for Search, Performance Max, and automatically created assets. It is included in every account at no extra cost.

Can AI run Google Ads?

It already runs most of the bidding, matching and placement. What it cannot do is decide what your business values. When I read 100 accounts in August 2026 the median account had 9 primary conversion actions, and Smart Bidding bids toward all of them. Set one or two conversion actions that mean money before you hand it more control.

Is AI Max worth turning on?

It can find searches your keywords miss, but check it with the search_term_match_source report after 30 days. Set URL exclusions first: in 84 PMax campaigns I pulled, 42 had served a page the advertiser never picked, and AI Max has the same final URL expansion switch. Campaigns with automatically created assets or campaign-level broad match start upgrading to AI Max from September 2026.

What is the best AI tool for Google Ads?

For most advertisers, Claude connected through Google's free MCP server is the best place to start, because it answers questions about your own account. Opteo (from $129 a month) is the easiest paid tool. Optmyzr suits agencies with many accounts, and Adalysis is strongest on ad testing.

Can I connect ChatGPT or Claude to Google Ads?

Yes. Google publishes an official MCP server with three read-only tools. You need a Google Cloud project with Explorer access and a Google login. Google retired developer tokens on 9 September 2026. It can read your account and answer questions, but it cannot change bids, keywords or budgets.

Does Google allow AI-generated ads?

Yes, under the same policies as any other ad. From July 2026 there is an AI label setting for ads in the EU, India and New York, and Google may label assets made with its own AI tools.
