Google Ads Search: Mastering Text Ads

Google Ads Search is the engine of paid acquisition. The oldest, most direct, and most profitable format in the Google Ads ecosystem. A user types a query. Your ad appears. They click. They land on your page. They convert.

No banners, no video, no multi-channel algorithm. Text. Intent. Conversion.

If you can only master one Google Ads format, this is the one.

How Search Ads Work

A user enters a query in Google. The algorithm evaluates in real time which ads to show among thousands of advertisers. This evaluation is based on two mechanisms: relevance and bidding.

The full process:

1. The user types a search
2. Google identifies advertisers whose keywords match
3. Google calculates the Ad Rank for each advertiser
4. Ads are ranked and displayed (or not)
5. The advertiser pays only if the user clicks

You never pay for impressions. Only for clicks. That's the CPC (cost per click) model.

The RSA Format: Responsive Search Ads

Since June 2022, RSAs are the only available text ad format. The old Expanded Text Ads (ETAs) can no longer be created.

RSA Structure

• Up to 15 headlines of 30 characters each
• Up to 4 descriptions of 90 characters each
• Final URL — the landing page
• Display path — 2 fields of 15 characters to customize the displayed URL

Google combines your headlines and descriptions to create ad variations. The algorithm tests combinations and optimizes toward the top performers.

How to Write Effective RSAs

The trap: writing 15 nearly identical headlines. "Google Ads Expert," "Your Google Ads Expert," "The Google Ads Expert You Need." The algorithm has nothing to optimize.

Each headline should bring a different angle:

• Headlines 1-3: main keyword + variants. "Certified Google Ads Expert," "Google Ads Specialist," "Google Ads Agency"
• Headlines 4-6: concrete benefit. "Cut Your CPA in Half," "ROI Measured Every Month," "+30% More Leads in 90 Days"
• Headlines 7-9: social proof / credibility. "80+ Clients Served," "Google Partner Certified," "4.9/5 Rating"
• Headlines 10-12: urgency / offer. "Free 30-Min Audit," "First Month No Commitment," "Quote in 24h"
• Headlines 13-15: direct CTA. "Request Your Audit," "Contact Us," "Launch Your Campaigns"

For descriptions:

• Description 1: core value proposition + differentiator
• Description 2: offer details + CTA
• Description 3: social proof or guarantee
• Description 4: complementary angle (methodology, experience)

Pin the headline containing your main keyword to position 1. For the rest, let the algorithm test.

Match Types

Match types determine which searches trigger your ads. It's the most critical lever in your Search campaign.

Exact Match [keyword]

Your ad only shows for searches that precisely match your keyword (and close variants: plurals, typos, very close synonyms).

• Keyword: [google ads agency]
• Triggers: "google ads agency," "adwords agency," "google advertising agency"
• Doesn't trigger: "how to create a google ads campaign"

Advantage: maximum precision. Every click is ultra-relevant. Disadvantage: limited volume. You miss relevant searches you didn't anticipate.

Phrase Match "keyword"

Your ad shows for searches that contain the meaning of your keyword, even with words before or after.

• Keyword: "google ads agency"
• Triggers: "best google ads agency NYC," "google ads agency for SMBs," "google adwords agency pricing"
• Doesn't trigger: "google ads training" (different intent)

The right balance between volume and relevance. The recommended match type at launch.

Broad Match

Your ad shows for any search Google considers related to your keyword. The interpretation is very... broad.

• Keyword: google ads agency
• Possible triggers: "freelance online advertising," "how to advertise on the internet," "digital marketing firm"

Advantage: maximum volume. Discovery of new queries. Disadvantage: without strict controls (negative keywords + Smart Bidding), 30-50% of budget goes to irrelevant searches.

Google pushes broad match. The data shows it works with Smart Bidding and a solid conversion history. Without those two conditions, broad match is a budget burner.

Quality Score

Quality Score (QS) is a 1-10 rating Google assigns to each keyword. It measures the quality of your ad and landing page relative to the user's search.

The Three Components

1. Expected CTR — Google estimates whether your ad will be clicked. Based on history.
2. Ad relevance — does your ad directly answer the query?
3. Landing page experience — is your page fast, relevant, and easy to use?

Why QS Is Crucial

Quality Score directly impacts your cost per click and your position. The formula:

Ad Rank = Maximum Bid x Quality Score (+ extensions + other factors)

A QS of 8/10 with a $3 bid beats a QS of 4/10 with a $5 bid. You pay less AND rank higher.

The concrete numbers:

• QS of 10: you pay about 50% less than the average CPC
• QS of 7: you pay the average CPC
• QS of 4: you pay about 50% more than the average CPC
• QS of 1: you pay 400% more — or your ads simply don't show

How to Improve QS

• CTR: write headlines with the exact keyword + a concrete benefit. Test variations.
• Relevance: one ad group = one search intent = one tailored ad. No catch-all groups with 30 different keywords.
• Landing page: dedicated page per ad group. The page title matches the keyword. The content answers the intent. Load time is under 3 seconds.

The Ad Rank Formula

Ad Rank determines whether your ad shows and at what position. The components:

1. Bid — the maximum amount you're willing to pay per click
2. Quality Score — the quality of your ad + landing page
3. Ad extensions — supplementary information (sitelinks, callouts, etc.)
4. Ranking thresholds — minimums Google imposes depending on the query
5. Search context — location, device, time, history

You can't simply "pay more" to be first. A competitor with a higher QS and complete extensions can beat you with a lower bid.

Ad Extensions

Extensions (renamed "assets" by Google) add supplementary information to your ad. They increase your ad's size, CTR, and improve your Ad Rank. They're free.

Essential Extensions

• Sitelinks — links to other pages on your site (contact, pricing, testimonials). Minimum 4.
• Callouts — short texts highlighting advantages. "No Commitment," "Free Audit," "Google Partner Certified."
• Structured snippets — lists of services or products. "Services: SEO, Google Ads, Analytics."
• Call — your phone number. Clickable on mobile.
• Location — your address (linked to Google Business Profile).

Recommended Extensions

• Price — display your pricing or price ranges directly in the ad
• Promotion — special offers with validity dates
• Image — a visual alongside your text ad (rolling out)
• Lead form — a form directly in the ad, no click to site needed

Rule: enable every relevant extension. No reason not to. Google picks which ones to show based on context.

Search Campaign Best Practices

Account Structure

One ad group = one search intent. Not a product, not a service. An intent.

Example for a Google Ads agency:

• Group 1: [google ads agency] — intent: find a provider
• Group 2: [google ads pricing] — intent: understand costs
• Group 3: [google ads audit] — intent: evaluate campaigns
• Group 4: [google ads training] — intent: learn

Each group has its own ads, tailored to the specific intent.

Negative Keywords

Just as important as positive keywords. Every week, review the search terms report. Exclude irrelevant searches. A mature account has 200-500 negative keywords.

Dedicated Landing Pages

The number one mistake in Search: sending all traffic to the homepage. Each ad group deserves a dedicated page that matches the keyword, answers the intent, and presents a clear CTA.

A dedicated landing page's conversion rate is 2-3x higher than a generic homepage.

Budget and Bidding

Start with manual bidding to understand your CPCs and the value of each keyword. Switch to Smart Bidding (Target CPA or Target ROAS) once you have 30+ conversions per month.

Daily budget should be enough to generate 10+ clicks per day on your main keywords. Below that, you don't have enough data to optimize.

Key Takeaways

Google Ads Search is the foundation of any paid acquisition strategy. It's the only format that targets active intent. When someone types a query, they're telling you exactly what they want. Your job: be there, with the right ad, pointing to the right page.

Search is complementary to other formats. Display and Demand Gen generate awareness. Performance Max automates multi-channel coverage. But Search remains the number one conversion engine. Check out our guide on Google Ads campaign types to understand how to combine these formats.
