Basic questions
1. What is Google Ads?
Google Ads is an online advertising platform where businesses pay to display ads on Google search results, websites, videos, and apps. Advertisers bid on keywords to show their ads to relevant audiences.
2. How does Google Ads work?
Google Ads operates on an auction system. Advertisers bid on keywords, and Google determines ad placement based on bid amount, ad quality, and relevance. Advertisers pay only when users click their ads (Pay-Per-Click model).
3. What are the main types of Google Ads campaigns?
The primary campaign types include Search, Display, Video, Shopping, App, and Performance Max.
Each serves different advertising goals and reaches audiences through different Google properties.
4. What is the difference between Google Ads and organic search?
Google Ads are paid placements that appear above or alongside organic results, marked as “Sponsored” or “Ad.”
Organic search results appear based on SEO and content relevance without payment.
5. What is PPC?
PPC stands for Pay-Per-Click, a digital advertising model where advertisers pay each time someone clicks their ad. Google Ads primarily uses this pricing model.
Tip: Always explain why PPC is useful—controlled budget, measurable ROI, and intent-based targeting.
6. What are impressions in Google Ads?
Impressions represent how many times an ad has been displayed to users, regardless of whether they clicked on it.
7. What is CTR in Google Ads?
CTR (Click-Through Rate) is the percentage of people who click on an ad after seeing it. It’s calculated by dividing clicks by impressions and multiplying by 100.
8. What is conversion in Google Ads?
A conversion occurs when a user completes a desired action after clicking an ad, such as making a purchase, filling out a form, or signing up for a newsletter.
9. What is the Google Ads auction?
The Google Ads auction is the process that determines which ads appear for each search query and in what order, based on factors like bid amount, quality score, and ad relevance.
10. What is ad rank?
Ad rank determines the position of an ad on the search results page. It’s calculated using the maximum bid, quality score, ad extensions, and expected impact of extensions and formats.
Google Ads Account Structure Questions
11. What is the structure of a Google Ads account?
The hierarchy follows:
Account → Campaign → Ad Group → Ads and Keywords.
Each level serves a specific organizational purpose and allows for different settings and controls.
12. Why is proper account structure important?
A proper structure enhances Quality Score, budget control, reporting clarity, optimization efficiency, and performance tracking. It allows better targeting and clearer reporting of results.Â
13. What is a campaign in Google Ads?
A campaign is a set of ad groups that share the same budget, location targeting, bidding strategy, and other settings. Each campaign focuses on a specific advertising goal.
14. What is an ad group?
An ad group contains a set of related keywords and the ads that target those keywords. Ad groups help organize campaigns by theme or product category.
15. How many ad groups should a campaign have?
There’s no fixed number, but campaigns typically contain 5-20 ad groups depending on product variety and targeting needs. Each ad group should focus on a tightly related set of keywords.
16. Can multiple campaigns share the same budget?
No, each campaign has its own budget. However, shared budgets can be created to distribute funds across multiple campaigns automatically.
17. What settings are configured at the campaign level?
Campaign-level settings include budget, bidding strategy, location and language targeting, ad scheduling, networks (search or display), and campaign type.
18. What settings are configured at the ad group level?
Ad group settings include keywords, bids (if not using campaign-level bidding), and the ads themselves. Targeting becomes more specific at this level.
19. Can different ad groups have different bids?
Yes, each ad group can have its own default bid, and individual keywords within ad groups can have custom bids that override the ad group default.
20. What happens if the account structure is poorly organized?
Poor structure leads to wasted budget, difficulty tracking performance, inefficient optimization, and lower quality scores. It makes campaign management time-consuming and ineffective.
Google Ads Campaign Types & Use Cases
21. What are Search campaigns?
Search campaigns display text ads on Google search results when users search for relevant keywords. They’re best for capturing high-intent users actively looking for specific products or services.
22. What are Display campaigns?
Display campaigns show visual banner ads across Google’s Display Network, which includes millions of websites, apps, and Google properties like YouTube and Gmail.
23. When should Display campaigns be used?
Display campaigns work well for brand awareness, remarketing to previous visitors, reaching broad audiences, and visual storytelling, where search intent isn’t as defined.
24. What are Video campaigns?
Video campaigns run video ads on YouTube and across the Display Network. They’re effective for brand building, product demonstrations, and engaging audiences with visual content.
25. What are Shopping campaigns?
Shopping campaigns showcase product images, prices, and merchant information directly in search results. They’re designed specifically for e-commerce businesses selling physical products.
26. What is Performance Max?
Performance Max is an automated campaign type that runs ads across all Google channels (Search, Display, YouTube, Gmail, Discover) using a single campaign with machine learning optimization.
27. When should Shopping campaigns be used?
Shopping campaigns are ideal for online retailers with product feeds who want to display visual product listings directly in search results with pricing and availability.
28. What are App campaigns?
App campaigns promote mobile apps across Google Search, Play Store, YouTube, and Display Network. They focus on driving app installs and in-app actions.
29. What is the difference between Search and Display campaigns?
Search targets users actively searching for specific terms, showing text ads.
Display targets users browsing websites, showing visual ads based on interests, demographics, or remarketing.
30. Can one campaign include both Search and Display?
Older campaign types allowed this, but best practice now separates Search and Display into different campaigns for better control, measurement, and optimization.
Keyword & Match Type Interview Questions
31. What are keyword match types?
Match types control how closely a user’s search query must match a keyword for the ad to appear. The main types are Broad Match, Phrase Match, and Exact Match.
32. What is Broad Match?
Match shows ads for searches related to the keyword, including synonyms, related searches, and variations. It offers the widest reach but less control.
33. What is Phrase Match?
Phrase Match shows ads when searches include the meaning of the keyword, allowing additional words before or after. It’s denoted by quotation marks around the keyword.
34. What is Exact Match?
Exact Match shows ads for searches that have the same meaning or intent as the keyword. It’s denoted by brackets around the keyword and offers the most control.
35. What are negative keywords?
Negative keywords prevent ads from showing for specific search terms. They help eliminate irrelevant traffic and reduce wasted spend on unqualified clicks.
36. Why are negative keywords important?
Negative keywords improve campaign efficiency by filtering out unwanted traffic, increasing CTR, improving quality scores, and ensuringthe budget goes toward qualified prospects.
37. What is the difference between search terms and keywords?
Keywords are terms that advertisers bid on. Search terms are actual queries that users type into Google that trigger ads to appear.
38. What tools help with keyword research?
Google Keyword Planner, Search Terms Report, competitor analysis tools, Google Trends, and third-party platforms like SEMrush and Ahrefs assist with keyword research.
39. How many keywords should an ad group have?
Best practice suggests 5-20 closely related keywords per ad group. Fewer keywords allow a tighter thematic focus and more relevant ad copy.
40. Can the same keyword appear in multiple ad groups?
While technically possible, this creates internal competition and makes performance tracking difficult. Each keyword should generally appear in only one ad group per campaign.
Bidding Strategy & Budget Questions
41. What is CPC?
CPC (Cost-Per-Click) is the amount an advertiser pays each time someone clicks their ad. It can be set manually or determined automatically by Google.
42. What is CPA?
CPA (Cost-Per-Acquisition) is the average cost to acquire one conversion. It’s calculated by dividing the total cost by total conversions.
43. What is ROAS?
ROAS (Return on Ad Spend) measures revenue generated for every dollar spent on advertising. It’s calculated by dividing revenue by ad spend.
44. What is manual bidding?
Manual bidding allows advertisers to set maximum CPC bids for keywords or ad groups. It provides complete control but requires ongoing management and optimization.
45. What is automated bidding?
Automated bidding uses Google’s machine learning to automatically adjust bids based on the likelihood of achieving specified goals like conversions or target ROAS.
46. What are Smart Bidding strategies?
Smart Bidding includes Target CPA, Target ROAS, Maximize Conversions, and Maximize Conversion Value. These strategies use machine learning and auction-time signals for optimization.
47. What is the difference between a daily budget and a lifetime budget?
Daily budget sets the average amount to spend per day. Google Ads doesn’t offer lifetime budgets; campaigns run continuously until paused or the daily budget is changed.
48. Can actual daily spend exceed the daily budget?
Yes, Google may spend up to twice the daily budget on high-traffic days, but monthly spend won’t exceed the daily budget multiplied by average days per month (30.4).
49. What is Target CPA bidding?
Cost-Per-Acquisition—the cost to generate one conversion. Target CPA automatically sets bids to get as many conversions as possible at the target cost-per-acquisition specified by the advertiser.
50. What is Maximize Clicks bidding?
Maximize Clicks automatically sets bids to get as many clicks as possible within the budget. It’s useful for driving traffic, but doesn’t optimize for conversions.
Ad Copy & Quality Score Questions
51. What is Quality Score?Â
Quality Score is a 1-10 rating that measures the quality and relevance of keywords, ads, and landing pages. Higher scores lead to better ad positions and lower costs.
52. What factors affect Quality Score?
The three main factors are expected CTR, ad relevance, and landing page experience. Each component is rated as above average, average, or below average.
53. Why does Quality Score matter?
Higher Quality Scores result in lower CPCs, better ad positions, and eligibility for ad extensions. It directly impacts campaign profitability and performance.
54. How can Quality Score be improved?
Improve Quality Score by increasing ad relevance to keywords, improving landing page experience, writing compelling ad copy, adding relevant extensions, and organizing campaigns tightly.
55. What are Responsive Search Ads?
Responsive Search Ads allow advertisers to provide multiple headlines and descriptions. Google automatically tests combinations and shows the best-performing versions.
56. How many headlines and descriptions can Responsive Search Ads have?
Advertisers can provide up to 15 headlines and 4 descriptions. Google will show up to 3 headlines and 2 descriptions in any ad combination.
57. What makes effective ad copy?
Effective ad copy includes the target keyword, a clear value proposition, a strong call-to-action, relevant extensions, and alignment with landing page content.
58. What are ad extensions?
Ad extensions add additional information to ads, such as phone numbers, location, additional links, prices, or promotions. They increase ad visibility and CTR.
59. Do ad extensions cost extra?
Ad extensions themselves are free. Advertisers only pay when someone clicks on the extension, typically at the same CPC as a regular ad click.
60. What is ad relevance?
Ad relevance measures how closely the ad copy matches the intent behind a user’s search query. Higher relevance improves Quality Score and campaign performance.
Conversion Tracking & Measurement
61. What is a conversion?
It is a valuable user action that advertisers want to track, such as purchases, form submissions, phone calls, or newsletter signups.
62. How are conversions tracked in Google Ads?
Conversions are tracked using conversion tracking tags (code snippets) placed on conversion pages or through imported goals from Google Analytics.
63. What is a conversion window?
The conversion window is the period after an ad click during which conversions are counted. Standard windows are 30 days for clicks and 1 day for views.
64. What is the difference between Google Ads and Google Analytics tracking?
Google Ads uses last-click attribution by default, but advertisers can now use data-driven attribution when sufficient data is available.
65. What are micro-conversions?
Micro-conversions are smaller actions that indicate user engagement but aren’t primary goals, such as video views, page scrolls, or add to cart.
66. What is the conversion rate?
Conversion rate is the percentage of clicks that result in conversions, calculated by dividing conversions by clicks and multiplying by 100. Example:(Conversions divided by clicks × 100)
67. Can conversions be imported from

A view-through conversion occurs when someone sees but doesn’t click a display or video ad, then later converts through another channel within the specified window.
69. How can conversion tracking be verified?
Conversion tracking can be verified using Google Tag Assistant, testing conversion actions manually, checking the “Status” column in conversion settings, or reviewing recent conversion data.
70. What is the conversion value?
Conversion value assigns a monetary amount to each conversion, allowing measurement of total revenue or value generated by campaigns rather than just conversion volume.
Optimization & Performance Questions
71. How can a campaign be optimized?
Optimization involves analyzing performance data, adjusting bids, refining keywords, improving ad copy, testing landing pages, adding negative keywords, and adjusting targeting settings.
72. How can CPC be reduced?

75. What is A/B testing in Google Ads?
A/B testing involves running multiple ad variations simultaneously to determine which performs better based on metrics like CTR, conversion rate, or CPA.
76. How long should A/B tests run?
Tests should run until statistically significant results are achieved, typically requiring at least 100 conversions or several weeks of data, whichever comes first.
77. What metrics indicate poor campaign performance?
Low CTR, high CPC, low Quality Score, high bounce rate, low conversion rate, and poor ROAS all indicate performance issues requiring attention.
78. How can the conversion rate be improved?
Improve conversion rate by optimizing landing pages, ensuring message match between ads and landing pages, simplifying conversion forms, improving page speed, and targeting qualified audiences.
79. What is the search terms report used for?
The search terms report shows actual queries that triggered ads. It’s used to find new keyword opportunities and identify irrelevant terms to add as negatives.
80. How often should campaigns be optimized?
Regular monitoring should occur weekly, with minor adjustments made as needed. Major changes should be made less frequently (bi-weekly or monthly) to allow data accumulation.
Troubleshooting & Practical Scenario Questions
81. Why might ads not be showing?
Common reasons include low bids, low Quality Score, disapproved ads, exhausted budget, restrictive targeting, policy violations, or the account being suspended.
82. What causes high impressions but low clicks?
This typically indicates poor ad relevance, weak ad copy, unattractive offers, or the ads appearing for irrelevant searches due to broad match keywords.
83. Why might the budget be spent too quickly?

Adjust budgets during peak seasons, create seasonal campaigns with specific messaging, use seasonal keywords, and utilize bid adjustments to capitalize on high-demand periods.
89. What if competitors are bidding on brand names?
Create branded campaigns with high bids, use exact match keywords, write strong ad copy emphasizing official status, and consider legal action if trademark infringement occurs.
90. How can click fraud be identified and prevented?
Monitor for unusual click patterns, high clicks with no conversions from specific IPs, and use Google’s automatic invalid click detection. Report suspicious activity to Google.
Advanced & Manager-Level Questions
91. How should campaigns be scaled?
Scale by gradually increasing budgets, expanding to new geographies, adding keyword variations, testing new campaign types, and using automated bidding once sufficient conversion data exists.
92. How should large budgets be managed?
Large budgets require sophisticated tracking, multiple campaigns for testing, automated rules for efficiency, regular performance reviews, and portfolio-level bid strategies.
