Factors affecting Quality Score
What is Quality Score?
Quality Score is a score from 1 to 10 assigned by Google to each keyword in your campaign, indicating how relevant and useful your ads and landing pages are to users.
Main Factors That Affect Quality Score
1. Expected Click-Through Rate (CTR)
What It Is:
- Google estimates how likely it is that someone will click your ad when it’s shown for a specific keyword.
Influenced By:
- Past performance of similar keywords.
- How compelling your headlines and descriptions are.
- How relevant your ad copy is to the keyword.
Tip:
Use strong, specific calls-to-action and keyword-rich ad text to boost CTR.
2. Ad Relevance
What It Is:
How closely your ad matches the intent behind a user’s search query and the keyword you’re targeting.
Influenced By:
- How well the keyword matches the ad’s message.
- Use of keywords in the headline and description.
- Overall clarity and relevance of the ad text.
Tip:
Create tightly themed ad groups with closely related keywords and customized ads.
3. Landing Page Experience
What It Is:
How relevant, useful, and easy-to-navigate your landing page is to users who click your ad.
Influenced By:
- Page load speed.
- Mobile-friendliness.
- Relevance of landing page content to the keyword and ad.
- Transparency (privacy policy, contact info).
- Ease of completing the conversion action.
Tip:
Make sure your landing page matches the ad’s promise and offers a smooth, helpful user experience.
4. Device and Location Performance
Google may also consider:
- How well your ad performs on different devices (mobile, desktop, tablet).
- How your ads perform in specific geographic areas.
- These signals are not separate Quality Score factors, but they may affect auction-time performance and bidding.
Why Quality Score Matters
- Higher Quality Score = Lower CPCs and better Ad Rank.
- Improves overall ad visibility and ROI.
- Helps Google show the most relevant ads to users.
Quick Summary:
| Factor | Description |
|---|---|
| Expected CTR | Likelihood of ad getting clicked |
| Ad Relevance | How closely the ad matches the searcher’s intent |
| Landing Page Experience | Quality, relevance, and usability of the landing page |
How Ad Rank impacts your cost and visibility
What is Ad Rank?
Ad Rank is the value Google uses to decide:
- If your ad shows
- Where it shows on the page (top or bottom)
- How much you pay per click
- It’s calculated every time your ad competes in an auction.
How Ad Rank is Calculated
- Ad Rank =
- Your bid
- Quality Score (Expected CTR, Ad Relevance, Landing Page Experience)
- Ad Extensions & Format Impact
- Auction-time signals (device, location, time, audience)
So, even with a lower bid, you can outrank a competitor if your ad quality is higher.
How Ad Rank Affects Your Cost (CPC)
Google uses Ad Rank to determine the minimum amount you need to pay to maintain your position.
Lower CPC for High Ad Rank
- If your Ad Rank is high (because of strong Quality Score and good extensions), you’ll pay less per click compared to competitors with lower-quality ads.
Example:
- You bid ₹100, and your competitor bids ₹120.
- If your Ad Rank is higher, you can still rank above them and possibly pay less (maybe ₹95) due to your quality advantage.
- So, Ad Rank helps you:
- Get better positions
- Pay less per click
- Improve ROI
How Ad Rank Affects Visibility
1. Ad Position
- Ads with higher Ad Rank show in top positions above search results.
- Lower Ad Rank might mean your ad appears at the bottom—or doesn’t show at all.
2. Eligibility to Appear
- If your Ad Rank is too low, your ad won’t enter the auction—even if your bid is high.
- This ensures only relevant, high-quality ads are shown.
3. Extensions & Formats
Higher Ad Rank increases the chance your ad shows with sitelinks, callouts, prices, images, etc., making it more eye-catching and boosting CTR.
Pro Tips to Improve Ad Rank
- Improve Quality Score by refining ad copy, keywords, and landing pages.
- Use relevant and complete ad extensions (sitelinks, call, image, price).
- Focus on ad relevance by aligning keywords, ads, and landing pages.
- Optimize mobile experience and page speed.
Tips to improve relevance and landing page experience
1. How to Improve Ad Relevance
Ad relevance is about how well your ad text matches the keywords you’re targeting and the user’s intent behind the search query.
Tips to Improve Ad Relevance:
A. Use Tight Keyword Grouping
- Break your campaigns into focused ad groups.
- Each ad group should contain closely related keywords.
- This allows you to create highly tailored ad copy for each theme.
Example:
- Bad → One ad group with “running shoes,” “basketball shoes,” and “boots”
- Good → Separate ad groups for each shoe type with unique ads
B. Include Primary Keywords in:
- Headlines (especially Headline 1)
- Descriptions
- Display Path URLs (optional but helpful)
This signals to Google—and users—that your ad is exactly what they’re looking for.
C. Match User Intent
- Make sure your ad speaks to what the user is trying to accomplish (buy, learn, compare, contact).
- For example, if someone searches “buy Nike running shoes,” don’t show an ad for all sports gear—show a direct product-focused ad.
D. Test Multiple Ad Variations
- Use Responsive Search Ads (RSAs) to test different headlines and descriptions.
- Google will serve the most relevant combinations based on search queries.
2. How to Improve Landing Page Experience
Landing page experience is about how useful, relevant, and easy-to-navigate your website is for visitors who click your ad.
A. Ensure Page Relevance
- Match the message and offer in your ad to the content on the landing page.
- If your ad mentions a product or discount, the user should land on that exact page—not the homepage.
Example:
- Ad: “Get 20% Off Running Shoes”
- Landing Page: Should feature the discounted shoes, not the main catalog.
B. Optimize for Speed
- Use tools like Google PageSpeed Insights or GTmetrix to improve load times.
- Compress images, reduce scripts, and use fast hosting.
- Aim for load times under 3 seconds, especially on mobile.
C. Make it Mobile-Friendly
- Ensure the page is responsive and easy to use on all devices.
- Buttons should be large enough to tap.
- Text should be readable without zooming.
D. Clear and Compelling Call-to-Action (CTA)
- Use prominent CTAs like “Buy Now,” “Sign Up,” or “Get a Free Quote.”
- CTAs should be above the fold and aligned with the goal of the ad.
E. Simple, Clean Layout
- Avoid clutter—use whitespace effectively.
- Guide the user with headings, bullet points, and visual hierarchy.
- Remove distractions that could lead to drop-offs.
F. Build Trust
- Add security seals, contact info, testimonials, and privacy policies.
- Use transparent messaging and clear return or refund policies.
