Most founders switch on Google Ads in their first month because every launch checklist says to. Three months later, the dashboard shows sales, the bank account shows less than it did, and nobody can say whether the ads worked.

Google Ads is a sensible first channel for a new store, since paid search reaches people who are already searching for what you sell. Whether it pays off depends on a handful of numbers you can work out before spending a cent. I’ve audited more than 1,300 online stores and noticed patterns you can avoid with this checklist.

This is the five-question readiness test I run on any new store, with a pass mark for each. To keep the math concrete, I’ll take one hypothetical startup selling dog harnesses through all five questions.

1. Do You Know What One Order Actually Earns?

The dog harness store’s average order value is $75. But only part of that $75 is yours to spend on ads. Most of it already belongs to your supplier, your courier, and your payment processor.

The part left over is your contribution margin: what remains from one order after every cost directly associated with it. Rent, software, and your own salary stay out because they don’t change when you sell one more harness.

For the harness store, it looks like this:

• $75 average order value
• Minus $22 for the harness, including freight to get it to you
• Minus $8 for shipping and packaging to the customer
• Minus $2.25 in payment processing fees, about 3%
• Minus $2.75 set aside for returns and exchanges
• $40 contribution margin per order

That $40 is the most the store can pay to win one sale and still break even on that order’s variable costs. Pay $41, and the sale loses a dollar, however good the ad report looks. Skip this number, and a young business can end up with revenue up and the bank account empty.

Leave repeat orders out of it for now. Established stores rightly count the value of customers who come back, but a store that’s six weeks old has no reliable evidence of who returns. The first order has to carry its own cost.

You pass this question when your contribution margin comes from your own supplier invoices and shipping costs.

2. Does Your Store Already Sell to Strangers?

If the people who find you through Instagram or organic search leave without buying, paid visitors may do the same, except you’re paying for each click.

Your conversion rate is the share of visits that end in an order, and Shopify shows it on the Analytics dashboard. Ignore launch week, when friends and family may have done most of the buying, and wait for at least 500 visits before putting much weight on the figure.

Under 1% is a signal to wait. It often points to problems with the product page, pricing, or shipping charges that appear at checkout. Each of those is cheaper to fix before you pay for traffic.

The harness store has had 1,600 visits since launch week and 40 orders, giving it a 2.5% conversion rate, which passes comfortably.

3. Can a Sale Afford What Google Charges?

Now set those two numbers against the market price, which costs nothing to estimate.

Google’s Keyword Planner shows estimated bid ranges for appearing near the top of search results. Enter the searches your customers would type, such as “no pull dog harness,” and use a representative click-cost estimate from the range.

Divide that click price by your conversion rate to estimate what one sale will cost.

Clicks at 85 cents with a 2.5% conversion rate mean 40 clicks per sale, so each sale costs about $34.

The harness store earns $40 per order and pays roughly $34 to win one. It passes with $6 to spare, which is thin.

Had Keyword Planner shown $1.40 clicks, each sale would cost $56, and every order from an ad would lose $16, assuming the same conversion rate.

Google Ads reports results as ROAS, or return on ad spend, which is sales revenue divided by ad spend.

Your break-even ROAS is your average order value divided by your contribution margin. For the harness store, that’s $75 divided by $40, or about 1.9.

A campaign returning less than $1.90 in revenue for each $1 spent on ads loses money at the contribution level, even while Google reports nearly double the money back.

We earn a commission if you make a purchase, at no additional cost to you.

4. Will Google Know When a Sale Happens?

Automated bidding can only learn from sales it can see.

Conversion tracking records each purchase and its value against the ad interaction that led to it. Without it, Google is guessing, and so are you.

Shopify’s Google & YouTube app can help set up purchase tracking for stores.

Before launch, check that Google Ads lists the purchase conversion as active and records the actual order value rather than a flat $1.

Once ads are running, compare a month of purchases in Google Ads with your store’s orders. If Google reports more purchases than your store actually received, investigate whether conversions are being counted more than once or whether reporting settings differ.

5. Can You Pay for 90 Days of Learning?

Treat the first campaign as a paid experiment. It needs enough sales to tell you something and enough money behind it that nobody panics in week two.

As a practical benchmark, I don’t judge a campaign or give Google a profit target until it has produced about 30 sales.

Optimizing Your Google Ads Campaign for Success

When it comes to running a successful Google Ads campaign, every detail matters. One key factor to consider is the conversion rate, as it directly impacts the number of clicks needed to achieve your goals. For example, a harness store with a 2.5% conversion rate would require 1,200 clicks to reach its target. At a cost of 85 cents per click, this translates to a budget of $1,020 over three months, or around $340 per month.

However, it’s essential to ensure that this budget is expendable. If losing $1,020 would have negative consequences for your business, such as impacting inventory orders or payroll, it’s best to wait until the financial situation is more secure, regardless of how well the campaign may perform.

Evaluating Your Readiness to Launch

Before diving into Google Ads, it’s crucial to assess your preparedness. Passing all five evaluation questions indicates that your store is ready to launch the campaign. However, failing to address certain issues may necessitate a delay.

If you fail questions related to tracking setup or budget allocation, it’s recommended to rectify these aspects before proceeding. On the other hand, failing questions pertaining to margins, website conversion rates, or cost-effectiveness suggests that further optimizations are required before launching the campaign.

Navigating Your First 90 Days with Google Ads

Days 1 to 30: Setting the Foundation

During the initial month, focus on setting up a simple Google Ads campaign targeted at beginners. Create a Search campaign centered around your best-selling product, utilizing exact match keywords for relevant search queries. Disable the Display Network and Search Partners to streamline your traffic source and set bidding strategies to maximize conversion value. It’s advisable to stick to the allocated daily budget and avoid unnecessary adjustments in the early stages.

Days 31 to 60: Refining Your Strategy

As you progress into the second month, regularly review the search terms report to identify irrelevant keywords that could be costing you money. By excluding negative keywords and pausing ineffective ones, you can optimize your ad spend and enhance campaign performance. Keep a close eye on keywords that exceed your break-even cost per sale to avoid wasteful expenditure.

Days 61 to 90: Assessing Performance and Scaling Up

By the third month, you should have a clearer picture of your campaign’s effectiveness. Calculate your Return on Ad Spend (ROAS) by comparing sales revenue attributed to ads with ad spend, ensuring it exceeds your break-even threshold. Additionally, evaluate your Marketing Efficiency Ratio (MER) across all channels to gauge overall marketing performance.

If your ROAS comfortably surpasses break-even, consider increasing your budget gradually to drive growth. Set a target ROAS slightly above break-even to guide bidding strategies towards profitable sales. Monitor results closely and adjust strategies as needed to maintain profitability.

Remember, if your campaign fails to meet profitability expectations after 30 sales, reassess your calculations and make necessary adjustments before proceeding. A well-optimized Google Ads campaign can significantly boost your business’s online visibility and drive conversions when executed strategically.
