What Are the Three Main Factors That Determine Ad Quality?

3 Main Factors to Determine Google Ads Quality

When businesses invest in paid advertising, one question matters almost immediately:

How do you determine ad quality?

Ad quality affects more than whether an advertisement looks professional. It can influence how relevant an ad is to its audience, how users respond to it, how efficiently advertising platforms deliver it, and ultimately how much value a campaign generates.

However, ad quality is not determined in exactly the same way across every advertising platform.

Google Ads has a specific Quality Score diagnostic framework. Meta Ads and LinkedIn use their own auction and relevance systems.

For businesses working with a paid ads agency in the US, understanding these differences is important because optimizing a Google campaign using the same approach as a Meta or LinkedIn campaign can lead to poor decisions.

For Google Ads, the three core Quality Score components are:

  1. Ad Relevance
  2. Expected Click-Through Rate (CTR)
  3. Landing Page Experience

Google identifies these as the “Big Three” components of ad quality.

Let’s look at each factor in detail and then compare how ad quality works across Google, Meta, Facebook, and LinkedIn.

What Is Ad Quality?

Ad quality refers broadly to how well an advertisement meets the needs and expectations of the audience and the advertising platform.

A high-quality advertisement generally has:

  • Strong relevance to the user’s intent
  • Clear messaging
  • A compelling reason to engage
  • Appropriate targeting
  • A strong user experience
  • A landing page that delivers what the advertisement promises
  • Relevant creative
  • A clear call to action

However, “ad quality” should not be confused with campaign performance.

An advertisement can have strong quality signals and still fail to generate profitable conversions because of factors such as:

  • Poor targeting
  • Weak offers
  • High competition
  • Incorrect pricing
  • Low market demand
  • Poor conversion tracking
  • Weak sales processes

Therefore, ad quality should be evaluated alongside business metrics such as:

  • CTR
  • Conversion rate
  • Cost per lead
  • Cost per acquisition
  • ROAS
  • Revenue
  • Qualified leads
  • Customer acquisition cost

What Are the Three Main Factors That Determine Google Ad Quality?

Google Ads provides the clearest formal framework for answering this question.

The three primary Quality Score components are expected CTR, ad relevance, and landing page experience.

1. Ad Relevance

Ad relevance measures how closely your advertisement matches the intent behind the user’s search.

For example, imagine someone searches:

“emergency plumber in Philadelphia”

An advertisement saying:

“Emergency Plumber in Philadelphia – 24/7 Service”

is more closely aligned with the search than a generic advertisement saying:

“Professional Home Services – Learn More.”

The first advertisement directly addresses the user’s apparent intent.

Google recommends matching ad language closely with users’ search terms and organizing keywords into groups that allow the ad copy to better match those searches.

How to Improve Ad Relevance

You can improve ad relevance by:

  • Grouping closely related keywords
  • Matching headlines to search intent
  • Using specific service terminology
  • Addressing the user’s problem
  • Aligning ad copy with the keyword theme
  • Creating dedicated landing pages
  • Avoiding overly generic messaging

The goal isn’t to insert keywords into an advertisement as many times as possible.

The goal is to make the advertisement useful and relevant to what the user is searching for.

2. Expected Click-Through Rate

Expected CTR estimates how likely your advertisement is to receive a click when it is shown.

Google describes expected CTR as the likelihood that your ad will be clicked when shown.

Consider two advertisements for the same service.

Ad A

Digital Marketing Services

Professional marketing solutions.
Learn more.

Ad B

Get More Qualified Leads With SEO

SEO strategies for U.S. businesses.
Book a strategy consultation.

The second advertisement may provide a clearer reason for the right audience to click.

Factors that can influence user response include:

  • Headline relevance
  • Offer clarity
  • Specific benefits
  • Differentiation
  • Call to action
  • Alignment with search intent
  • Ad assets

Google recommends reviewing CTR and conversion metrics when evaluating ad performance.

Important: CTR Is Not the Same as Conversion Rate

A high CTR does not automatically mean a successful campaign.

An advertisement could generate thousands of clicks but very few leads.

For example:

10,000 impressions → 1,000 clicks → 5 leads

might be less valuable than:

5,000 impressions → 400 clicks → 30 leads

Therefore, CTR should be analyzed together with conversion rate and business outcomes.

3. Landing Page Experience

The third major component is landing page experience.

This evaluates how relevant and useful the landing page is after someone clicks the advertisement.

Google specifically recommends making sure the landing page matches the user’s search, the advertisement, and the expected action.

For example, if your advertisement says:

“20% Off Emergency Plumbing Services”

the user should not land on a generic homepage.

They should arrive at a relevant page where they can immediately understand:

  • What service is being offered
  • What the offer means
  • Where the service is available
  • How to claim the offer
  • How to contact the business

Elements of a Strong Landing Page

A high-quality landing page should generally provide:

  • Strong message match
  • Clear headline
  • Relevant content
  • Fast and usable experience
  • Mobile-friendly design
  • Simple navigation
  • Trust signals
  • Relevant proof
  • Clear CTA
  • Easy conversion process

Google notes that users are more likely to leave when they don’t immediately find what they expected after clicking an advertisement.

How to Determine Google Ad Quality

Google provides Quality Score as a diagnostic tool on a 1–10 scale.

Within Google Ads, advertisers can review:

  • Quality Score
  • Expected CTR
  • Ad relevance
  • Landing page experience

Google recommends using Quality Score as a diagnostic tool rather than treating the 1–10 score itself as a primary performance KPI.

For example:

Quality Component Status
Expected CTR Above average
Ad Relevance Average
Landing Page Experience Above average
Quality Score 8/10

In this example, the advertiser might investigate the ad relevance component rather than simply trying to push the overall score from 8 to 10.

Does Google Ad Quality Affect Ad Cost?

Yes, ad quality can affect how efficiently advertisements compete in Google’s auction.

Google explains that higher-quality ads can contribute to stronger Ad Rank and can often result in lower CPCs.

However, Quality Score itself is not directly used as an auction input.

This distinction is important.

Google’s Quality Score is a diagnostic measure. Auction-time evaluations of factors such as expected CTR, ad relevance, and landing page experience contribute to Ad Rank.

Does Increasing Your Bid Improve Quality Score?

No.

Google explicitly states that bidding affects Ad Rank but does not affect the assessment of ad quality itself.

This means advertisers should not assume:

Higher bid = higher ad quality.

Instead, focus on:

Better relevance + better user experience + stronger expected engagement.

How to Determine Facebook Ad Quality?

Facebook advertising is now part of the broader Meta Ads ecosystem.

Meta does not use Google’s 1–10 Quality Score system.

Instead, advertisers should evaluate Meta ad quality using a broader combination of:

  • Creative quality
  • Audience relevance
  • Engagement
  • Ad relevance
  • User response
  • Conversion performance
  • Delivery efficiency
  • Feedback and diagnostics available within Ads Manager

Therefore, when someone searches for Facebook ad quality, they should not expect to find an exact equivalent of Google’s Quality Score.

What Should You Measure for Meta Ads Quality?

For Meta advertising, look at metrics such as:

CTR

A useful indicator of whether the creative and offer are generating interest.

Engagement

Depending on the campaign, consider:

  • Likes
  • Comments
  • Shares
  • Saves
  • Video engagement

Conversion Rate

Measure how many users complete the desired action after clicking or interacting with the advertisement.

Cost Per Result

Evaluate the cost associated with your campaign objective.

Frequency

A high frequency can sometimes indicate that the same audience is seeing the advertisement repeatedly.

Creative Performance

Compare:

  • Images
  • Videos
  • Hooks
  • Headlines
  • Offers
  • CTAs

The important point is that Meta Ads quality should be evaluated in the context of the campaign objective and audience, rather than through a single universal score.

How to Determine Meta Ads Quality?

A practical Meta Ads quality evaluation can use a framework like this:

Area What to Examine
Creative Visual quality and message
Relevance Audience-to-offer alignment
Engagement User interaction
CTR Click interest
Conversion Desired actions
Cost per result Efficiency
Frequency Audience saturation
Feedback User response
ROAS Revenue efficiency

For example, an advertisement may have an attractive image and high engagement but produce very few qualified leads.

That would tell you something important:

Creative engagement is not necessarily the same as business performance.

How to Determine LinkedIn Ad Quality?

LinkedIn uses an advertising auction in which bid and ad relevance are important factors in determining whether an advertisement appears. LinkedIn states that relevancy reflects the likelihood that members will interact with the ad and can incorporate factors such as member activity, page context, ad content, and targeting.

LinkedIn also states that content quality and relevance are important performance factors because engaging content can help ads compete in auctions.

Therefore, LinkedIn ad quality should be evaluated around:

  • Audience relevance
  • Ad content
  • Targeting
  • Engagement
  • CTR
  • Conversion performance
  • Cost per result
  • Bid competitiveness

LinkedIn Ad Quality Example

Imagine a B2B software company targeting:

U.S. CIOs and IT Directors

An advertisement saying:

“Reduce IT Infrastructure Costs With Enterprise Automation”

is likely to be more relevant to that audience than a generic advertisement saying:

“Discover Our Software.”

The more closely the message, targeting, and offer correspond to the audience, the stronger the potential relevance.

Google Ad Quality vs Meta Ad Quality vs LinkedIn Ad Quality

These platforms should not be evaluated using exactly the same framework.

Platform Main Quality/Ranking Considerations Useful Metrics
Google Ads Expected CTR, ad relevance, landing page experience Quality Score, CTR, conversion rate, CPC
Meta Ads Creative, relevance, engagement, user response, campaign performance CTR, engagement, cost per result, conversions, ROAS
LinkedIn Ads Relevance, content quality, targeting, bid CTR, engagement, conversions, cost per result

Google provides a formal Quality Score framework, whereas Meta and LinkedIn use their own delivery and auction systems.

What Is the Most Important Factor in Ad Quality?

There isn’t one universal factor that determines quality across every advertising platform.

However, one principle appears consistently:

Relevance to the user matters.

Google explicitly describes relevance to user intent as central to ad quality.

LinkedIn similarly incorporates ad relevancy into its auction.

For Meta, the relationship between audience, creative, engagement, and campaign objective is similarly important when evaluating performance.

This leads to a practical advertising principle:

Show the right message to the right audience at the right stage of the buying journey.

How Can a Paid Ads Agency Improve Ad Quality?

A professional paid ads agency in the US should not focus exclusively on increasing budgets.

A strong optimization process should include:

1. Audience Research

Understand:

  • Who is the customer?
  • What problem are they solving?
  • What do they search for?
  • What motivates them?
  • What objections do they have?

2. Search Intent Analysis

For Google Ads, understand the intent behind each keyword.

Someone searching:

“emergency plumber near me”

has a very different intent from someone searching:

“how to fix a leaking faucet.”

The advertising strategy should reflect that difference.

3. Ad Copy Testing

Test:

  • Headlines
  • Benefits
  • Offers
  • CTAs
  • Differentiators
  • Messaging angles

4. Creative Testing

For Meta and LinkedIn, test different:

  • Images
  • Videos
  • Hooks
  • Formats
  • Messages
  • Offers

5. Landing Page Optimization

Make sure the landing page delivers what the advertisement promised.

6. Conversion Tracking

Track meaningful actions rather than clicks alone.

7. Continuous Testing

Paid advertising is not a one-time setup.

Campaigns need continuous:

  • Testing
  • Analysis
  • Audience refinement
  • Creative iteration
  • Keyword optimization
  • Budget allocation
  • Landing page improvements

What Does a High-Quality Ad Look Like?

A high-quality ad should answer three questions quickly:

What is being offered?

The user should immediately understand the product or service.

Why should I care?

The advertisement should communicate a relevant benefit or solution.

What should I do next?

The CTA should make the desired next step clear.

For example:

Get More Qualified Leads With Google Ads

Target high-intent searches with conversion-focused campaigns designed for your business.

Book a Strategy Consultation

The message is specific, the benefit is clear, and the next step is obvious.

Common Mistakes That Reduce Ad Quality

Using Generic Ad Copy

Generic messages often fail to differentiate the business.

Sending Every Click to the Homepage

A homepage may not be the best destination for every advertising intent.

Targeting Too Broadly

Broad audiences can produce irrelevant clicks and weak engagement.

Ignoring Search Intent

A keyword does not tell the entire story.

You need to understand what the person actually wants.

Optimizing Only for CTR

A high CTR is not enough if the traffic doesn’t convert.

Ignoring Landing Page Experience

A strong advertisement cannot compensate indefinitely for a poor landing page.

Focusing Only on Quality Score

Google explicitly recommends using Quality Score as a diagnostic tool rather than a primary KPI.

How Should Businesses Measure Overall Ad Quality?

Instead of using one number, evaluate the entire advertising funnel.

Impression → Click → Landing Page Visit → Engagement → Conversion → Qualified Lead → Customer → Revenue

At each stage, ask:

  • Are the right people seeing the ad?
  • Are they clicking?
  • Are they engaging?
  • Are they finding what they expected?
  • Are they converting?
  • Are the leads qualified?
  • Is the campaign profitable?

This approach gives you a much more accurate picture of advertising quality.

What Should You Look for in a Paid Ads Agency in the US?

If you are evaluating a paid ads agency in the US, don’t choose an agency simply because it claims to deliver “high-quality ads.”

Ask how it measures quality.

A strong agency should be able to explain:

  • How it researches audiences
  • How it identifies intent
  • How it structures campaigns
  • How it evaluates ad relevance
  • How it tests creative
  • How it evaluates landing pages
  • How it tracks conversions
  • How it measures cost per acquisition
  • How it calculates ROAS
  • How it reports campaign performance
  • How frequently it optimizes campaigns

You should also ask for relevant case studies and examples of measurable outcomes.

Final Takeaway

So, what are the three main factors that determine ad quality?

For Google Ads, the answer is clear:

  1. Expected CTR
  2. Ad Relevance
  3. Landing Page Experience

Google identifies these as the three primary Quality Score components.

For Meta Ads and Facebook Ads, evaluate creative quality, audience relevance, engagement, delivery, and conversion performance rather than looking for a Google-style Quality Score.

For LinkedIn Ads, relevance, content quality, targeting, and auction competitiveness are important considerations.

Ultimately, excellent advertising comes down to a simple principle:

Relevant audience + relevant message + strong user experience + measurable business outcome.

For businesses investing in paid advertising, working with an experienced paid ads agency in the US can help turn these principles into a structured process of research, testing, optimization, and measurement.

At MetaSense Marketing, paid advertising should be evaluated beyond clicks and impressions. The focus should be on reaching the right audience, improving ad relevance, creating stronger landing-page experiences, and connecting campaign performance to qualified leads, conversions, and business growth.
