Google Ads tooling splits along a line that matters more than any feature comparison: does the tool build a campaign, or does it improve one you already built? Most of the established names are the second kind. They are excellent at it, and completely useless if you are staring at an empty account. This compares seven tools on Google specifically, and starts with the question that decides quality more than anything else — where the keyword data comes from.
Start here: where do the keywords come from?
This is the single most useful question to ask any AI Google Ads tool, and it is rarely answered on the pricing page. There are two possibilities, and they produce very different results.
Generated by a language model
The tool asks an AI to suggest keywords for your business. The output reads convincingly and often includes terms nobody searches for. You pay to discover which ones had no traffic behind them.
Pulled from Keyword Planner
The tool queries Google's own Keyword Planner through the Ads API for real monthly volumes and competition. Less imaginative, considerably more honest — it is the same data a media buyer would open Keyword Planner to check.
A language model can write a beautiful ad for a keyword with eleven searches a month. Nothing in the output tells you that. This is the most common way an AI-built Google campaign quietly fails: not bad copy, but a keyword set with no demand underneath it.
Optimisers: they improve a campaign you already have
Optmyzr
The serious practitioner tool. Deep rule engines, bulk edits, scripts, sophisticated reporting. If you manage substantial Google spend and know exactly what you want changed, it is superb leverage. It assumes real PPC expertise and will not build a campaign for you from a description of your business.
Opteo
Surfaces prioritised, specific recommendations on an existing account — bid adjustments, negative keywords, budget shifts — with one-click application. Cleaner and gentler than Optmyzr, aimed at the same person: someone who already has campaigns running.
Adzooma
Simpler, cheaper, aimed at small businesses, with opportunity-based suggestions across Google, Meta and Microsoft. Approachable. The depth is correspondingly shallower — it is a helpful assistant on an existing account rather than something that will construct a well-structured campaign for you.
💡 All three are good products being asked the wrong question when someone says "build me a Google campaign". They optimise; they do not originate. If you have no campaign yet, none of them solves your actual problem.
Builders: they create the campaign
Google Smart Campaigns
Google's own simplified product. Free, native, and genuinely the lowest-friction way to get something live. The trade-off is control and visibility: you get very little say over keywords, structure and where the money goes, and limited insight into why it spent what it spent. Fine as a first step, frustrating as a permanent arrangement.
AdScale
Builds and runs cross-channel campaigns across Google Search, Display and Meta, optimised hard for return on ad spend using product-catalogue data. Strong for an online store. For a business selling consultations there is no purchase event to optimise against, which removes most of the mechanism.
Synter Media
Enterprise AI agent operator, generating creative and shipping it across 20+ networks by API. Built for teams running many channels at scale, and priced for them.
Adyft
Builds Google Search campaigns from your website or a description of your business, using live Keyword Planner volumes through the official Google Ads API rather than model-invented keywords. Keyword selection applies explicit rules — intercepting existing demand, conquesting competitor terms, and affordability against your stated budget — so the keyword set has a reason for existing. Campaigns are built with responsive search ads, extensions, and income and age targeting where the country supports it. Geo targeting resolves to city level across 163 countries and is verified against the Ads API rather than assumed.
After launch, an AI keyword optimiser queries live performance through GAQL and acts on it, so the campaign changes based on what happened rather than staying as generated. It also runs Meta from the same place, which matters because search and social are usually the same budget viewed two ways. One specific safeguard worth mentioning: currency is taken from the connected Google account and a guard blocks a campaign being built in a mismatched currency — that mismatch silently produces bids that never win the auction, and it is easy to miss.
A note on business size, because this gets miscategorised
AI ad tools are often assumed to be for beginners or very small businesses. For some products that is accurate. It is worth checking rather than assuming, because the underlying engine and the plan tier are different things.
Adyft is a case in point: the campaign engine is identical at every tier — the same Keyword Planner data, the same selection rules, the same post-launch optimiser — and what changes with the plan is how many campaigns and client accounts it covers. Agency tiers are built for running many separate client accounts with each client's campaigns strictly isolated. That is a different proposition from a simplified tool that is genuinely capped at small, simple campaigns.
Which one fits you
You are an experienced PPC manager
Optmyzr for depth, Opteo for a cleaner recommendation flow. Both multiply expertise you already have.
You have no campaign and no PPC background
A builder, not an optimiser. Google Smart Campaigns to test the water; Adyft if you want a real campaign structure with visibility into it.
You want Google and Meta in one place
Adyft or AdScale — AdScale if you sell products with a catalogue, Adyft if you sell enquiries and appointments.
You are an agency with many clients
Optmyzr if your team are practitioners; Adyft's agency tiers if you want campaigns built and run per client with isolation between accounts.
Ecommerce, ROAS is the only metric
AdScale. Catalogue and purchase-event optimisation is the whole game and lead-gen tools do not replace it.
What to check before you pay
- 1Where do the keywords come from — Keyword Planner through the API, or a language model? Ask directly; the answer changes campaign quality more than any other factor.
- 2Does it build campaigns or only optimise existing ones? Most established Google tools are optimisers, which is useless on an empty account.
- 3Is it your own Google Ads account? You should keep the account, the billing relationship and the history if you leave.
- 4Does it keep working after launch, or is it a one-time generator? A campaign frozen as generated decays.
- 5Does it handle currency and geo correctly for your country? A currency mismatch produces bids that never win, and it fails silently.
- 6Does it take a percentage of spend? Agencies typically take 10–20% on top of the ad budget itself.
💡 Worth stating plainly: no tool here fixes a landing page that does not convert. Google Ads buys you a click. Everything after the click is still your job, and it is where most underperforming campaigns are actually losing.
