What is Quality Score?

Quality Score & Ad Rank is a 1 to 10 rating assigned by Google to each keyword in your ad campaign. It reflects how relevant and useful your ads and landing pages are to users searching with that keyword.

A higher Quality Score means better ad performance, lower costs, and improved visibility.

Key Factors That Affect Quality Score

1. Expected Click-Through Rate (CTR)

Definition: Google estimates the likelihood that someone will click your ad when it’s shown.

What Affects CTR:

  • Historical performance of similar keywords
  • Strength and relevance of your ad copy
  • Use of action-oriented language and keyword-rich content

Pro Tip: Write compelling headlines and descriptions with strong calls-to-action like “Shop Now”, “Get a Quote”, or “Start Your Free Trial”.

2. Ad Relevance

Definition: How closely your ad matches the user’s search intent and targeted keyword.

What Affects Relevance:

  • Inclusion of keywords in headlines and descriptions
  • The alignment between keyword intent and ad message
  • The clarity and focus of the ad

Pro Tip: Organize your campaign into tightly themed ad groups. Each group should have specific keywords and tailored ad copy to match user intent.

3. Landing Page Experience

Definition: Measures how relevant, user-friendly, and valuable your landing page is to someone who clicks on your ad.

What Impacts Experience:

  • Page load speed (especially on mobile)
  • Relevance of the landing page content
  • Mobile responsiveness and usability
  • Transparency (e.g., privacy policies, contact info)
  • Ease of completing the desired action

Pro Tip: Match the landing page content with your ad offer. If your ad promotes “20% off shoes”, the page should clearly feature those shoes and discount info.

4. Device and Location Signals

Although not direct Quality Score factors, Google considers:

  • Ad performance on mobile vs. desktop
  • Geographic performance trends

These signals influence ad auction outcomes and can impact how often and where your ad appears.

Why Quality Score Matters

  • Higher Quality Score = Lower CPCs (Cost-Per-Click)
  • Better Ad Rank = Higher positions in search results
  • Greater relevance = More conversions and better ROI

What is Ad Rank?

Ad Rank determines:

  • Whether your ad shows
  • Its position on the search results page
  • How much you pay per click

Ad Rank is calculated every time your ad competes in an auction.

How Ad Rank is Calculated

Ad Rank =

  • Your Bid
  • Your Quality Score
  • Ad Extensions and format impact
  • Auction-time signals (device, location, audience, time)

Even with a lower bid, a higher quality ad can outperform competitors and win better ad placements.

How Ad Rank Affects CPC (Cost-Per-Click)

Google sets a minimum bid you need to maintain your ad position, based on Ad Rank.

Example:

You bid ₹100, your competitor bids ₹120.
If your Ad Rank is better, you may still rank above them and only pay ₹95.

Better ad quality = lower CPC and higher ROI.

How Ad Rank Impacts Ad Visibility

  • Ad Position: Higher Ad Rank = Top placement; Lower Ad Rank = Bottom or no appearance.
  • Eligibility: Very low Ad Rank may disqualify your ad from showing.
  • Extensions: Higher Ad Rank enables sitelinks, callouts, images, and more.

Tips to Boost Quality Score & Ad Rank

Improve Ad Relevance

  • Group Keywords Tightly: Use separate ad groups for different keyword themes.
  • Include Keywords in: Headlines, Descriptions, and Display URLs.
  • Match User Intent: Serve ads that solve the user’s exact query.
  • Test Variations: Use Responsive Search Ads (RSAs) to test multiple headline and description combinations.

Improve Landing Page Experience

  • Match Message: Ensure ad offer aligns with page content.
  • Speed Optimization: Use tools like PageSpeed Insights or GTmetrix.
  • Mobile-Friendly Design: Ensure all elements are usable on mobile devices.
  • Clear CTA: Include strong and visible calls-to-action above the fold.
  • Clean Layout: Avoid clutter and use white space and bullets.
  • Build Trust: Use SSL, privacy policy, testimonials, and contact info.
