General Google Ads Metrics:
1. Impression
The number of times your ad was shown to users. Each time your ad appears on someone’s screen, it counts as an impression.
2. Clicks
The number of times users clicked on your ad. This shows direct engagement with your ad.
3. CTR (Click-Through Rate)
The percentage of users who clicked your ad out of those who saw it. It is calculated as (Clicks ÷ Impression) x 100. A high CTR generally indicates that your ad is relevant to your audience.
4. Cost
The total amount spent on your ad campaign. It includes all costs for the clicks or impressions generated.
5. Avg Cost (Average Cost)
The average amount spent per click or impression. This helps track costs over time without specific action details.
6. Conversions
The number of desired actions taken by users after interacting with your ad (such as purchases, sign-ups, subscribes or downloads).
7. Conv Rate (Conversion Rate)
The percentage of clicks that led to conversions. It’s calculated as (Conversion ÷ Clicks) x 100. A higher rate indicates a successful campaign.
8. Avg CPC (Average Cost Per Click)
The average cost you pay for each click on your ad. Calculated as (Total Cost ÷ Total Clicks). Useful for budgeting and cost management.
9. Avg Target CPA (Cost Per Acquisition)
The average cost you’re willing to pay per conversion. Google aims to keep your cost per conversion at or below this target.
10. Quality Score
A measure of the quality and relevance of your ad, keywords, and landing page. Higher scores can lower your ad costs and improve ad positions.
11. Ad Strength
An indicator of how effective your ad is in delivering relevant content to users. It’s based on the variety and relevance of the ad assets used (headlines, descriptions, images).
What's the difference between Quality Score and Ad Strength ?
Quality Score vs Ad Strength
Quality Score: This is a metric that rates the relevance and quality of your keywords, ad text, and landing page for a specific keyword. It’s primarily used to determine your ad’s eligibility and rank in the auction. A higher Quality Score can lower your costs and improve your ad’s position.
Ad Strength: This metric focuses on the effectiveness and variety of your ad assets (like headlines, descriptions, and images) specifically for responsive ads. It gives feedback on how well your ad elements are likely to engage your audience, guiding you to improve creativity and relevance.
12. Interaction
The number of times users engage with your ad, like clicks for text ads or views for video ads.
13. Interaction Rate
The percentage of interactions per impression. Calculated as (Interactions ÷ Impressions) x 100. A higher rate indicates stronger engagement.
14. Max CPC (Maximum Cost Per Click)
The highest amount you’re willing to pay for a click on your ad. Google will never exceed this amount per click.
15. Avg CPM (Cost Per Thousand Impressions)
The average cost you pay per 1,000 impressions of your ad. Commonly used in Display and Video campaigns.
16. Viewable CTR (Click-Through Rate for Viewable Impressions)
Measures the click-through rate of ads only when they’re actually viewable by users (50% of the ad on screen for one second or more).
Video Campaign-Specific Metrics
1. View
The total number of times users watched or interacted with your video ad. For In-stream ads, a “view” typically means watching at least 30 seconds or engaging with the video.
2. View Rate (In-stream, In-feed, Shorts)
The percentage of views compared to impressions.
- In-stream ads: Ads that play before or during YouTube videos. A view is counted if watched for 30 seconds or more, or if the user interacts with it.
- In-feed ads: These ads appear in YouTube’s feed, like search results or the homepage. The view rate is based on how often users choose to watch your ad.
- Shorts ads: Ads that appear in YouTube Shorts, the view rate is the percentage of views from users swiping up to watch the ad in full-screen.
3. Avg CPV (Average Cost Per View)
The average cost you pay per video view. It’s calculated by dividing the total cost by the number of views.
4. Earned Likes
The additional likes on your YouTube videos that happen after a user views your ad. It helps track user interest in your content.
5. Earned Subscribers
The number of new subscribers gained from users who watched your ad. This metric is valuable for building a loyal audience.
6. Watch Time
The total time users spend watching your video ad, in seconds. Longer watch times can indicate stronger viewer interest.
7. Avg Watch Time/Impr
(Average Watch Time per Impression): The average time users spent watching your ad per impression. It’s useful for understanding how engaging your ad is.
8. Engagement
The total number of interactions with your ad, including likes, shares, and comments. Higher engagement often leads to better brand recall.
9. Engagement Rate
The percentage of engagements per impression is calculated as (Engagement ÷ Impressions) x 100. It shows the effectiveness of the ad in creating user interactions.
10. Cost/Sub (Cost per Subscriber)
The average cost for each new subscriber gained from your ad. Calculated as (Total Cost ÷ Earned Subscribers). It’s useful for budgeting and evaluating the ad’s effectiveness in building an audience.
Additional Notable Metrics
Impression Share
The percentage of impressions your ad received compared to the total available impressions. This metric helps you understand how often your ads show up when they’re eligible.
Absolute Top Impression Share
The percentage of impressions your ad received in the very first position. It indicates premium ad positioning.
Bounce Rate (Landing Page)
The percentage of visitors who clicked your ad but left without interacting further. A high bounce rate may suggest your landing page needs improvement.
Conversion Value
The total revenue generated from conversions. This helps track the return on investment (ROI) from Google Ads.
ROAS (Return on Ad Spend)
The revenue generated per dollar spent on ads. Calculated as (Conversion Value ÷ Total Ad Spend). It’s important for understanding campaign profitability

Google Ads bidding
Google Ads bidding is the process of telling Google how much you’re willing to pay when someone interacts with your ad: whether it’s a click, a view, or an impression. Your bidding strategy tells Google what your goal is, such as getting more conversions, clicks, visibility, or sales value.
How it works?
When a user searches for something, Google enters your ad into an auction. Google looks at your bid, ad relevance, expected performance, and Quality Score to calculate how competitive your ad is.
With automated bidding, Google’s AI adjusts your bids in real time to help you get the best possible results within your budget. All you need to do is choose the right bidding strategy based on your goal.
Types of Bidding Strategies
Non-Automated:
> Manual CPC: You set bids yourself.
Semi-Automated:
> Enhanced CPC (ECPC): Google adjusts your manual bids slightly to help you get more conversions.
Fully Automated:
Smart Bidding:
> Maximize Conversions: Great for service-based businesses focused on leads.
> Maximize Conversion Value: Ideal for e-commerce, where the value of a sale matters.
> Target CPA (tCPA): You tell Google the cost per lead you want, and Google optimizes toward that number.
> Target ROAS (tROAS): Suitable for product-focused or e-commerce businesses where you need a specific return on ad spend.
> Maximize Clicks: Great for businesses that want to drive as much traffic as possible to their website within a set budget. This strategy is useful when you’re in the early stage of gathering data, testing keywords, or building awareness.
Other Automated Strategies:
> Target Impression Share: Great for businesses that want to maximize visibility on Google Search, such as appearing at the top of the page or on the first page. This is ideal when brand exposure is the priority or when you want to dominate visibility for specific keywords.
> Cost-per-view (CPV) – mainly for YouTube ads
> Viewable CPM (vCPM) – focuses on impressions for Display ads
New Google Ads Account Best Practices:
When setting up a new Google Ads account, it’s best to start with a traffic-focused campaign objective. In the beginning, aim to get as many clicks as possible so Google can collect data and understand your ideal audience.
Once enough data is gathered, you can gradually switch to conversion-focused bidding. This helps Google learn your conversion goals and automatically find users who are more likely to convert.
Google Keyword Planner
Google Keyword Planner helps beginners discover relevant keywords and understand how often people search for them. It also provides estimated CPC ranges so you can plan your budget more effectively.
For example, if you search “running shoes,” Keyword Planner will show keyword variations like “best running shoes for men” along with their monthly search volume and expected cost per click.
Google Ads Important Notes:
Do not directly link to affiliate products/ Do not directly promote affiliate product links.
Do not use retargeting or redirect tracking URLs as your landing page.

Why does Google Ads show “no impressions”?
Don’t panic! First, ask yourself: Is this a brand-new Google Ads account?
If yes, it normally takes 3–7 days for Google’s AI and machine learning system to study your ads before impressions start to appear.
Next, check your Ad Status
Eligible – Your ad is approved and can run.
Eligible (Limited) – Your ad is approved but restricted (usually due to policy or budget).
Not Eligible – Your ad cannot run because it violates policy or settings.
Paused – You have manually stopped the ad.
Removed – You deleted this ad or campaign.
Not Serving – Your ad is not currently showing due to settings, budget, or learning phase.
Ended – The campaign has passed its end date.
Step 2: Check your Keyword Status
Disapproved – Your keyword cannot run due to policy issues.
Under Review – Google is still reviewing your keywords.
Eligible – Your keyword can trigger ads.
Eligible (Limited) – The keyword can run but is restricted by policy or low quality.
Step 3: Check Your Quality Score & Bidding
If your bid is too low, Google may not show your ads at all.
Low bid = below the first page bid estimate.
Tip: Use Google Keyword Planner to check the average CPC for your industry and adjust your bids accordingly.
Other Reasons Why Your Ads Have No Impressions
Another possible reason is that your keywords have low search volume or your landing page has low relevance.
1. If your keyword search volume is low, what should you do?
You have a few options:
Do nothing and wait for search volume to increase naturally.
Remove the low-volume keyword and replace it with keywords that have actual demand.
Change the keyword match type (e.g., from exact match to broad match) to capture more searches.
2. If Google says “Low Ad Relevance” (landing page / webpage not relevant), what should you do?
Add more highly relevant keywords that match your landing page content.
Ensure your landing page clearly contains the keywords you’re targeting.
TL;DR — What to check when your ads have no impressions

Check Keyword status
Factors that affect status may include: Quality Score, bidding, search volume, and landing page relevance.
