This guide compiles practical steps from account registration, four-layer structure, keyword matching, responsive ad writing, quality score, bidding strategies to conversion tracking and weekly optimization checklists. It also covers common issues such as smart mode automatically spending budget, missing negative keywords, and ads pointing directly to the homepage.
From Spending on Ads to Precise Investment
Many business owners feel overwhelmed by the numerous buttons when first encountering the ad platform. Practical experience shows budget shortage is rarely the main issue; problems usually stem from poor structure, lack of negative keywords, and landing pages directing to the homepage.
If you have read the introductory strategy article and understand paid ads, keyword matching and bidding basics, this article will guide actual backend operations.
This is an operation manual. Each section explains the exact screen, button location and value to fill. It is recommended to open the backend and follow along.
Creating an Ad Account
Registration Process
- Go to ads.google.com and click "Get started"
- When prompted to create the first campaign, click "Switch to Expert Mode" at the bottom
- In Expert Mode select "Create an account without creating a campaign"
- Confirm country/region, time zone and currency
- Done, you now have a clean account
Why skip Smart Mode? Smart Mode lets the system decide keywords, bids and audiences automatically, leaving users unable to see what is happening. Unless testing for only a short period, Expert Mode is recommended.
Billing Setup
After entering the account, set up payment first:
- Click top-right "Tools & Settings" → "Billing" → "Billing settings"
- Choose credit card or bank transfer
- Fill in company information
- Monthly electronic invoices will be received
Understanding the Backend Interface
After login there are five main areas:
- Left navigation: switch between levels
- Top toolbar: date range and filters
- Central data table: shows selected dimensions

- Top-right "Tools & Settings": account settings and conversion management

Campaign Structure and Levels
The account uses a four-layer structure:

- Campaign: independent budget, location and schedule
- Ad group: semantically related keywords and ads
- Keywords & Ads: trigger conditions and displayed content
Structure Design Principles
One campaign corresponds to one marketing goal.
| Campaign | Goal |
|---|---|
| Brand terms | Defend brand searches |
| Service terms - Web design | Acquire leads |
| Service terms - SEO | Acquire leads |
| Competitor terms | Grab competitor traffic |
One ad group corresponds to one theme. Keywords within the same group should be highly related so precise ad copy can be written.

Step 1: Choose campaign goal
- Click left "Campaigns" → blue "+" → "New campaign"
- Select "Leads"
- Check the conversion actions to track
- Select "Search" type
Step 2: Campaign settings
- Campaign name: use clear naming, e.g.
Search_Service_WebDesign_Taipei - Networks: uncheck partners and Display Network
- Location: select specific cities
- Language: Traditional Chinese, English
- Daily budget: set daily cap
Step 3: Bidding strategy
Recommended flow for new accounts:
| Stage | Recommended strategy | Reason |
|---|---|---|
| First 2 weeks | Manual CPC + Enhanced CPC | Accumulate data |
| After 15+ conversions | Maximize conversions | Let the system start learning |
| 30+ conversions/month | Target CPA | Stably control cost |
Step 4: Create ad groups
- Enter ad group name

Step 5: Write ads
This part is detailed in the Responsive Search Ads section later.
Step 6: Review and publish

Keyword Strategy and Management
Using Keyword Planner
- Tools & Settings → "Planning" → "Keyword Planner"
- Select "Discover new keywords"
- Enter 3-5 core terms
- Review average monthly searches, competition and bid estimates
Keyword grouping strategy
Using a web design company as example, groups can include brand, service, location and price-related terms.
Keyword Match Types Explained
The platform provides three match types plus negative keywords.
Broad Match
Enter directly without symbols. Widest reach but easily triggers irrelevant searches. Not recommended for new accounts.
Phrase Match
Add quotes. Search must contain the phrase. Suitable for most situations.
Exact Match
Add brackets. Most precise but smallest reach. Suitable for brand and high-converting keywords.
Practical advice
- New ad groups: start with phrase + exact mix
- Check search terms report weekly
- Once stable, raise bids on high-converting keywords
Negative Keyword Management
Negative keywords are an important way to control budget.

Essential negative lists
Regardless of industry, almost always exclude: free, tutorial, job, academic, irrelevant locations.
Search terms report analysis
This is weekly must-do work. Suggest spending 15 minutes every Friday checking relevant and irrelevant search terms.
Responsive Search Ads Writing

Description writing tips
- First sentence states the point directly
- Naturally include 1-2 keywords

- End with a call-to-action
Landing page selection
Landing pages should be highly relevant to ad copy. If the ad promotes a specific service, link directly to the service page instead of the homepage.
Ad Assets
Ad assets increase exposure for free.
Essential ad assets
| Type | Description | Setting suggestion |
|---|---|---|
| Sitelinks | Show extra page links | At least 4 |
| Callouts | Title + list format | Service types |

Quality Score and Ad Rank
Quality Score directly affects ad rank and cost per click.
Three elements of Quality Score
Expected CTR, ad relevance, landing page experience.
Why Quality Score matters
The ad rank formula is bid multiplied by Quality Score. Higher Quality Score can lower cost per click.
Viewing Quality Score
- Left "Keywords" → "Search keywords"
- Check Quality Score related columns
- Focus on keywords scoring below 5
Bidding Strategy Selection and Setup

Bidding strategy progression path
Stage 1: Manual CPC to accumulate data. Stage 2: Enhanced CPC to let the system learn. Stage 3: Maximize conversions to let AI take over. Stage 4: Target CPA for precise cost control.
Conversion Tracking Setup
Without conversion tracking, all optimization is guesswork.
Common conversion actions
| Conversion type | Applicable scenario | Tracking method |
|---|---|---|
| Form submission | Contact form, quote request | Thank-you page URL or event |
| Phone calls | Direct inquiries | Call tracking |
| Page views | Price page, service page | Page view |

Setting conversion via Google Tag
- Tools & Settings → "Measurement" → "Conversions"
- Click "New conversion action" → "Website"

Importing conversions via GA4
If events are already set in GA4, they can be imported directly into Google Ads.
Conversion tracking verification
Use Google Tag Assistant to verify the code fires correctly.
Audience Settings
Besides keywords, audiences can narrow or expand reach.
Audience types
| Type | Description | Setting method |
|---|---|---|
| Custom segments | Based on search interest or browsing behavior | Tools → Audience manager → Custom segments |
| Affinity | Google-defined interest categories | Ad group → Audiences → Browse |
| In-market | Actively researching specific products/services | Ad group → Audiences → Browse |
| Remarketing | Previously visited the site | Need to set remarketing code first |
| Similar audiences | Similar to existing customers | Automatically generated from remarketing lists |
Observation vs Targeting
Observation does not restrict reach and is used first to collect data. Targeting only shows ads to the selected audience.
Remarketing
Remarketing shows ads to previous visitors who did not convert. Conversion rates are usually 2-3 times higher than regular ads.
Setting up remarketing
- Confirm Google code is installed site-wide
- Tools & Settings → "Shared Library" → "Audience manager"
- Create remarketing lists
Creating remarketing campaigns
- New campaign → "Display"
- Select remarketing list
- Exclude converted visitors
- Budget suggestion: 10-20% of total budget

Spending control tips
- Set account-level monthly cap
- Use ad scheduling
- Exclude poor-performing time slots
- Device bid adjustments
Common Issues and Troubleshooting
Ad approved but no impressions
Possible reasons: bid too low, budget exhausted, keyword search volume too low, location too narrow, account still under review.
Many clicks but no conversions
Possible reasons: landing page mismatches ad, landing page loads too slowly, keywords too broad, conversion tracking broken, form or CTA unclear.
Cost per click too high
Possible reasons: Quality Score too low, competition too fierce, match type too broad, bidding strategy unsuitable.
Conversion tracking shows 0
Troubleshooting steps: confirm code installed with Tag Assistant, confirm conversion action status, manually trigger one conversion, wait 24-48 hours for data.
Conclusion: Continuous Learning, Data-Driven
Google Ads is a system that requires ongoing learning and tuning. The first 1-2 months are a learning period focused on data collection. Once data exists, gradually optimize keywords, copy, bids and audiences. It is recommended to run for at least 3 consecutive months and review data weekly to see compounding optimization effects.
