By following this guide, you will set up a Google Ads search campaign structured for conversions, not vanity metrics. From account settings to bid strategy, you can complete the core build in two to three hours. The result is a campaign that tracks real business outcomes and spends your budget on the searches most likely to convert.

What You'll Build

  • A Google Ads search campaign with a conversion-first structure and correct tracking in place
  • Tightly themed ad groups using exact and phrase match keywords to improve Quality Score
  • Responsive search ads written to match commercial intent, tested with at least three headline combinations
  • A smart bidding strategy set up to optimise for your actual conversion goal, not just clicks
  • A negative keyword list that blocks irrelevant traffic from day one

Prerequisites

  • A Google Ads account (free to create at ads.google.com)
  • Google Tag Manager or direct site access to install a tracking tag
  • A conversion action defined: form submission, purchase, phone call, or appointment booking
  • A landing page specific to the campaign (not just your homepage)
  • A starting budget of at least $30 to $50 AUD/SGD/CAD/USD per day to generate enough data

Step 1: Set Up Conversion Tracking Before You Spend a Dollar

Most campaigns fail because they are optimised on the wrong signal. Clicks are not conversions. Set up conversion tracking first, before you write a single ad.

In your Google Ads account, go to Goals > Conversions > New conversion action. Choose Website as the source. Define a conversion that matches a real business outcome. For a service business in Australia or Canada, this is usually a form submission or a phone call lasting more than 60 seconds. For an e-commerce store, it is a purchase event with revenue value attached.

Install the Google tag using Google Tag Manager. In GTM, create a new tag using the Google Ads Conversion Tracking template. Paste in your Conversion ID and Conversion Label from the Google Ads interface. Set the trigger to fire on your thank-you page URL or a custom event from your form tool.

After publishing, use the Tag Assistant Chrome extension to verify the tag fires on a test conversion. Do not move to Step 2 until this is confirmed. Running a campaign without verified conversion tracking is the single fastest way to waste budget.

Common pitfall: If you are tracking a form submission, make sure the thank-you page has a unique URL. If your form submits without redirecting, you need a custom event trigger instead of a page-view trigger.

Step 2: Choose the Right Campaign Goal and Bidding Strategy

When you create your campaign, Google will prompt you to select a goal. Choose Leads or Sales depending on your business model. Do not select Website traffic. That goal optimises for clicks, not outcomes.

For your bid strategy, the right choice depends on your data volume. If your account has fewer than 30 conversions in the past 30 days, start with Maximise Conversions with a Target CPA left blank. Once you have 30 or more conversions recorded, switch to Target CPA and set a realistic cost-per-acquisition based on your actual data, not a guess.

Set your campaign type to Search. Uncheck the Search Network Partners and Display Network options. Those placements dilute search intent data and make it harder to read your results cleanly.

Step 3: Build Tightly Themed Ad Groups

Why does ad group structure matter so much?

Google's Quality Score rewards relevance between your keyword, your ad copy, and your landing page. A tightly themed ad group keeps all three aligned. Higher Quality Scores reduce your cost-per-click, often by 20 to 50 percent compared to a loosely structured campaign.

Aim for three to five keywords per ad group. Group keywords by the same core intent. For a Singapore-based SaaS company, one ad group might cover project management software for teams, team project management tool, and project tracking software. A separate ad group covers asana alternative, monday alternative for small teams, and similar comparison searches. These are different intents and need different ads.

Use a mix of exact match and phrase match keywords. As of 2026, broad match has improved significantly but still carries risk for new campaigns with limited data. Save broad match for campaigns that already have strong conversion history.

Format your keyword list like this in the Google Ads editor or interface:

[project management software for teams]   → exact match
"project tracking software"               → phrase match
[team task management tool]               → exact match
"small business project management"       → phrase match

Step 4: Write Responsive Search Ads That Match Intent

Each ad group needs at least one Responsive Search Ad (RSA). Google tests combinations of your headlines and descriptions to find the best-performing version. You provide the raw material.

Write 10 to 15 headlines. Each headline has a 30-character limit. Include your primary keyword in at least two headlines. Write headlines that speak to different buyer concerns: one on the outcome, one on the offer, one on trust signals, one on urgency or specificity.

Examples for a US-based HR software company:

Headline examples:
- HR Software for Small Teams
- Trusted by 5,000+ Businesses
- Start Free. No Credit Card Needed.
- Cut Onboarding Time by 40%
- Built for Teams Under 50 People
- Replace Spreadsheets Today
- US-Based Support Included
- 14-Day Free Trial

Write four descriptions at 90 characters each. Use at least one description to state your unique value clearly. Use another to include a call to action that matches the landing page button.

Pro tip: Pin one headline in position one to your primary keyword phrase. This guarantees the keyword appears in every ad combination, which helps Quality Score and click-through rate.

Step 5: Add Extensions That Improve Click Rate

Google calls these Assets as of 2024. Add the following before launching:

  • Sitelinks: Four links to specific pages (pricing, case studies, free trial, contact). Each sitelink increases ad real estate and gives users a shortcut to high-intent pages.
  • Callouts: Short phrases like "No long-term contract" or "NDIS registered" or "BBB Accredited". Add six to eight.
  • Structured Snippets: List your service categories or features.
  • Call Asset: Add your phone number if phone leads matter to your business. This adds a tap-to-call button on mobile.
  • Lead Form Asset: Relevant for service businesses where users prefer not to leave the search results page.

Assets do not cost extra. They expand your ad and improve click-through rate. Missing assets is one of the most common oversights in SMB campaigns.

Step 6: Build Your Negative Keyword List

What searches should you block from day one?

Negative keywords prevent your ads from showing on irrelevant searches. A new campaign without negatives will waste 15 to 30 percent of its budget on bad traffic within the first week.

Add these negatives as a starting point for most campaigns:

Negative keywords (broad match unless noted):
- free
- jobs
- careers
- salary
- tutorial
- how to
- reddit
- wikipedia
- DIY
- course
- certification
- template (if you sell a service, not a template)

Add them at the campaign level so they apply to every ad group. After your first week of data, go to Keywords > Search Terms and review what searches actually triggered your ads. Add any irrelevant terms as negatives. Do this weekly for the first month.

Step 7: Configure Audience Signals and Location Targeting

Set your location targeting to the specific cities or regions your business serves. For a Canadian SMB in Toronto, target Ontario or specific postal code ranges, not all of Canada. Broader location targeting wastes budget and dilutes performance data.

Add audience signals under Audiences > Observation. Add your website visitors, customer lists (if uploaded), and in-market audiences relevant to your category. Set them to Observation, not Targeting. This lets you see bid adjustment data without restricting who sees your ads.

Set a mobile bid adjustment if your landing page is not fully optimised for mobile. Go to Devices and reduce mobile bids by 20 to 30 percent until you have data showing mobile converts at the same rate as desktop.

Step 8: Set Your Budget and Launch

Set a daily budget that allows for at least five to ten clicks per day. If your average CPC is $4, a $30 daily budget gives you around seven clicks. That is enough to collect data, but you will need two to four weeks before making major optimisation decisions.

Before hitting publish, run through this checklist:

  • Conversion tracking fires correctly on a test action
  • Each ad group has one RSA with an ad strength of at least "Good"
  • All ad groups have at least three to five tightly matched keywords
  • Negative keyword list is applied at campaign level
  • Location targeting matches your actual service area
  • Sitelinks and callout assets are added
  • Landing page loads in under 2.5 seconds on mobile (check with PageSpeed Insights)

The landing page check matters. A slow page kills Quality Score and conversion rate together. If your page scores below 70 on mobile in PageSpeed Insights, address that before launching.

Step 9: Review Performance and Optimise in Week Two

Do not make changes in the first five days. Smart bidding needs time to learn. After day seven, review these metrics:

  • Impression share: If it is below 50 percent, your budget or bid is too low for your target keywords.
  • Click-through rate (CTR): A healthy CTR for search ads is 5 to 10 percent. Below 3 percent signals a headline or relevance problem.
  • Search terms report: Add new negatives and look for new keyword opportunities.
  • Conversion rate: If you are getting clicks but no conversions, the issue is the landing page, not the ad.

If you are planning other growth activities alongside your paid search work, it is worth running a brand health assessment to understand how your brand perception affects conversion rates across all channels.

At Lenka Studio, we have seen campaigns for clients in Singapore and Australia improve conversion rates by 30 to 60 percent simply by tightening ad group structure and fixing landing page speed in the first two weeks of optimisation.

Frequently Asked Questions

How long does it take for a Google Ads search campaign to show results?

Most campaigns need two to four weeks to exit the learning phase and start producing stable data. Smart bidding algorithms require 30 to 50 conversion events to optimise reliably, so campaigns with lower traffic budgets take longer to mature.

What is a good cost per conversion for Google Ads?

It depends on your industry and average order value. A lead worth $2,000 in revenue can support a $100 to $200 cost per lead. As a starting benchmark, aim for your cost per conversion to be no more than 10 to 20 percent of the revenue that conversion generates.

Should I use broad match keywords in a new campaign?

Not at the start. Broad match works well when your campaign has strong conversion history and a well-trained smart bidding model. For a new campaign, stick to phrase match and exact match until you have at least 30 conversions recorded.

Why are my ads not showing even though the campaign is active?

The most common reasons are a daily budget that is too low for your target CPCs, keywords with low search volume, overly restrictive negative keywords, or an ad under review. Check the Status column on your keywords tab for specific error messages from Google.

Do I need a separate landing page or can I send traffic to my homepage?

A dedicated landing page almost always outperforms a homepage. Homepages have too many navigation options and competing messages. A landing page matched to the specific ad group intent, with one clear call to action, typically improves conversion rate by 20 to 40 percent compared to a generic homepage.

Next Steps

Once your campaign is live and collecting data, the next priorities are: improving your landing page with A/B tests, expanding to a second ad group targeting a different keyword theme, and setting up remarketing audiences to re-engage visitors who did not convert on the first visit.
