Google Ads Agency: How to Choose One and What to Expect

Google Ads Agency: How to Choose One and What to Expect

Agency proposals arranged for comparison

A Google Ads agency plans, builds, runs and optimizes your paid search campaigns so that ad spend turns into calls, form fills and booked jobs. The right one owns the details you don’t have time for: account structure, keywords, ad copy, landing pages, bids, conversion tracking and reporting. The wrong one sends you a monthly report full of clicks and no customers. This guide explains what an agency actually does, how fees are usually structured, and how a Phoenix-area business can tell a good fit from a bad one before signing.

TL;DR

  • A Google Ads agency handles the full job: account setup, keyword and search-term work, ads, landing pages, bids and budgets, conversion tracking and reporting.
  • Agency fees are typically a flat monthly fee or a percentage of ad spend, sometimes with a setup fee. Your ad budget is paid to Google separately.
  • Judge an agency on business outcomes (leads, booked appointments, cost per lead), not clicks or impressions.
  • Before you sign, confirm that you own the ad account, that conversion tracking is set up properly, and what the reporting will look like.
  • Arizona Strategy manages Google Ads for Phoenix, Scottsdale, Tempe, Mesa and Chandler businesses, tied to the website and follow-up that turn clicks into customers.

What a Google Ads agency does for your business

Google Ads is an auction. Every time someone searches for “AC repair near me” or “cosmetic dentist Scottsdale,” Google decides which ads show, in what order and at what price. An agency’s job is to win the searches that lead to revenue and avoid paying for the ones that don’t.

In practice that covers a defined set of work:

  • Account structure. Campaigns and ad groups organized around services and locations, so budget goes where the money is made. A plumber who also does water heater installs should not have both under one bucket.
  • Keyword and search-term work. Choosing what to bid on, then reviewing the search terms report regularly to add negative keywords and cut wasted spend.
  • Ads and landing pages. Writing ad copy that matches search intent and sending clicks to a page built to convert, not to a generic homepage.
  • Bids and budgets. Adjusting bidding strategy, daily budgets and schedules as results come in.
  • Conversion tracking. Recording the actions that matter: phone calls, form submissions, booked appointments.
  • Reporting. Explaining cost per lead, return on ad spend and what changed during the month, in plain language.

An agency can also run campaigns beyond search, such as Performance Max, Display, YouTube and Local Services Ads. For most local service businesses, though, search campaigns and Local Services Ads carry the bulk of the results, and getting those right comes first.

Do you need an agency or can you run it in-house?

Some owners run Google Ads themselves successfully, especially with a small budget and a simple offer. An agency makes sense when one or more of these is true:

  • You are spending enough that a few percentage points of wasted spend add up to real money each month.
  • Nobody on your team has time to review search terms, adjust bids and test ads every week.
  • Leads come in but you can’t tell which campaigns produce booked jobs.
  • Your competitors in Phoenix have been bidding for years and your cost per click keeps climbing.
  • You want ads, website and follow-up handled as one system instead of three separate vendors.

Google itself offers one-to-one help for getting a first campaign running, which can be enough to launch. Ongoing optimization is where a dedicated team earns its fee.

What good Google Ads management includes

When you compare proposals, check each one against the same six-part scope. Missing pieces are where the cost surprises show up later.

1. Account audit and structure

If you already have an account, a good agency starts by auditing it: what is spending, what is converting, and what is leaking budget. For a new account, it builds a structure around your highest-margin services first. Our article on 11 Google Ads mistakes Phoenix dental practices make shows the kind of issues an audit typically catches, from loose match types to missing negatives.

2. Keyword research and ongoing search-term review

Keyword research is the start, not the finish. Search terms change with seasons, and Arizona is a clear example: demand for AC repair, pool service and roofing moves with the weather. A management plan should include a recurring review of what people actually typed before clicking. If you work in map-driven categories, it also helps to understand how Google Maps advertising fits next to search campaigns, since both compete for the same local intent.

3. Ad copy and landing pages

Clicks cost money; landing pages decide whether that money pays off. Ask to see the page a campaign will send traffic to. If the page loads slowly, buries the phone number or doesn’t match the ad, no amount of bid tuning fixes it. This is why we pair ad management with web design and conversion optimization for clients who need it.

4. Bids and budgets

Smart bidding strategies work well only when they are fed accurate conversion data. The agency should explain which strategy it is using, why, and what budget the account needs to exit the learning phase. A budget that is too thin for the market spreads clicks across too many keywords and learns nothing.

5. Conversion tracking

This is the part most often done badly. If tracking counts every page view as a conversion, or misses phone calls entirely, the account optimizes toward the wrong goal. We walk through the process in a step-by-step guide to Google Ads conversion tracking written around a Peoria contractor site, and the same logic applies to any local service business.

6. Reporting you can read

Google’s own developer documentation recommends reporting on impressions, clicks, cost, conversions, conversion value and ROAS on a weekly and monthly basis, with ROAS defined as total conversion value divided by total cost. For a service business, translate that into three numbers you care about: cost per lead, cost per booked job and revenue from ads. A report that stops at click-through rate hasn’t answered the question you hired the agency to answer.

6. Reporting you can read

How Google Ads agencies charge

Pricing varies by agency, so ask for the fee structure in writing before comparing proposals. Most fall into a few models:

Model How it works Where it fits
Flat monthly fee A fixed amount each month regardless of spend Small and midsize accounts with steady budgets
Percentage of ad spend The fee scales with what you spend on Google Larger or fast-growing budgets
Setup or onboarding fee A one-time charge for audit, tracking and build New accounts or major rebuilds
Performance-based Part of the fee ties to leads or revenue Less common, requires clean tracking

Whatever the model, two points matter. First, your ad spend is paid to Google directly and is separate from the agency’s fee. Second, a term commitment should come with clear exit terms. Ask what happens to the account, the data and the tracking if you leave.

Our own engagements are sold as paid consulting engagements, typically paid upfront for a contracted term. We don’t publish a fixed price for Google Ads management because the right scope depends on your market, budget and goals, so we scope it after a conversation about your business.

What a realistic budget looks like

There is no universal number. Keep these factors in mind:

  • Competition. Cost per click in Phoenix for legal, home services and healthcare terms is typically higher than for low-competition niches. Check the keyword planner inside your account for your own terms.
  • Job value. A roofing replacement or dental implant can justify a higher cost per lead than a $150 service call.
  • Close rate. If you convert 1 in 3 leads, you can afford a higher cost per lead than if you convert 1 in 10.

A simple example: if an average job brings in $1,200 in revenue and you close 25% of leads, each lead is worth about $300 in revenue. A cost per lead well under that leaves room for payroll, materials and profit. Run this math before you decide on a monthly spend, not after.

How to evaluate a Google Ads agency

Use this checklist when you interview agencies. It works for any provider, including us.

Ask who owns the account

You should own your Google Ads account, with the agency linked to it through its manager account. That keeps your campaign history, conversion data and billing in your hands. Any agency that insists on running ads in an account only it controls is asking you to leave your data behind if you ever switch.

Check the credentials, then look past them

Google runs a Partner program with a Partner badge and a Premier Partner badge. According to Google’s own help page, becoming a Partner involves meeting requirements in three areas: performance (a minimum optimization score of 70%), spend (a 90-day ad spend of $10,000 across managed accounts) and certifications. A badge shows an agency meets those thresholds. It does not tell you whether the agency understands your market, so treat it as one input.

Check the credentials, then look past them

Ask how they define a conversion

A good answer names phone calls, form fills and booked appointments, and explains how each is tracked. A weak answer talks about traffic and impressions.

Ask to see a sample report

You should be able to read it in five minutes and know whether the month was good. Look for cost per lead, lead volume by campaign and a written explanation of changes.

Ask about local experience

Phoenix, Scottsdale, Tempe, Mesa and Chandler each have their own competitive mix. An agency that has worked with local service businesses will know that summer drives different searches than winter and that “near me” intent matters. Look at their local case examples and ask what they would do first in your specific category.

Ask what happens after the click

Ads bring the click. The website, call handling and follow-up decide whether it becomes revenue. Ask how the agency handles missed calls, form responses and review requests, or how it coordinates with whoever does.

Read the contract terms

Check the term length, what is covered, who pays for tools and landing pages, and how you can end the agreement. You should leave with a clear scope, not a vague promise.

Red flags to watch for

  • Guaranteed rankings or guaranteed lead counts. Google Ads results depend on budget, competition and your offer.
  • Reports built around impressions and clicks only.
  • No access to your own account.
  • Setup done by a template that ignores your services, service area and margins.
  • A pitch that never asks about your close rate, average job value or capacity.

Our perspective on Google Ads agencies

We hear the same story from Arizona business owners: they are paying for clicks, they have a report that looks busy, and they can’t say how many paying customers came from it. That is a measurement problem before it is an ads problem.

Our view is that a Google Ads agency should be judged on the outcome the business needs: qualified leads, booked appointments and revenue. That means conversion tracking that counts calls and forms correctly, landing pages built to convert, and reporting that connects spend to jobs.

It also means looking at the whole path. Search ads work best alongside a Google Business Profile that is optimized, a website that loads fast and speaks to the searcher’s need, and follow-up that answers every lead quickly. We build and manage those pieces together, so a lead doesn’t disappear between the ad and the invoice.

Our goal is to give local businesses the marketing capabilities larger competitors have, without enterprise costs. For paid search, that means disciplined account structure, regular search-term review and plain-English reporting.

Paid search buys visibility today. SEO and Google Maps visibility build it over time. Most local businesses do best with a mix, and the balance changes with budget and urgency.

  • Google Ads gives you immediate placement on high-intent searches and fast data about which keywords convert.
  • Local and technical SEO reduces your dependence on paid clicks over time. Our Phoenix SEO and AI search optimization work focuses on both Google results and visibility in AI platforms such as ChatGPT, Gemini and Perplexity.
  • Google Business Profile and reviews influence how you appear in map results and how many searchers choose you once they see you.

The data from ads can feed the rest. Search terms that convert in Google Ads often point to pages worth building or improving for organic search.

FAQ

How much does a Google Ads agency cost?

Agencies usually charge a flat monthly fee or a percentage of ad spend, and some add a setup fee. Your ad budget is paid to Google on top of that. Ask each agency for the fee structure, term length and what is included in writing so you can compare proposals on equal terms.

Is $10 a day enough for Google Ads?

It can work for a narrow test in a low-competition niche and a small service area. In competitive Phoenix markets, a budget that small often buys too few clicks to learn from. Estimate your cost per click in the keyword planner, then work backward from the number of leads you want.

What should a Google Ads management company include?

At minimum: account structure, keyword and search-term management, ads and landing pages, bid and budget management, conversion tracking, and regular reporting on cost per lead and return on ad spend. Anything less leaves a gap you will end up filling yourself.

Should I own my Google Ads account?

Yes. Your business should own the account and link the agency to it through its manager account. That way your campaign history, conversion data and billing stay with you, whichever agency you work with.
