1. What is Google Ads?

Answer:

Google Ads is an internet advertising system created by Google, in which advertisers bid to show advertisements on Google's search engine results page (SERP), YouTube, Gmail, and on the Google Display Network.

It enables companies to reach specific audiences according to keywords, location, language, device, demographics, and others.

If a Delhi bakery desires to promote "best chocolate cake near me," Google Ads can display their ad atop search results when individuals in the region search for similar keywords.

2. What are various types of Google Ads campaigns?

Answer:

There are a number of campaign types available in Google Ads:

Search Campaigns – Text ads on Google search pages.

Display Campaigns – Banner ads on websites and apps.

Shopping Campaigns – Product listings for online stores.

Video Campaigns – Ads played on YouTube.

App Campaigns – Promote mobile apps across Google networks.

Performance Max – A goal-driven campaign that relies on automation on all Google inventory.

Pro Tip: Uncodemy's hands-on sessions demonstrate setting up each campaign type from scratch.

3. What is Quality Score in Google Ads?

Answer:

Quality Score is a number (1 to 10) Google uses to measure the relevance and quality of your keywords, ads, and landing page. A higher Quality Score can result in lower CPC (Cost Per Click) and better ad positions.

It's based on:

CTR (Click-Through Rate)

Ad relevance

Landing page experience

Example:

Your ad is attracting more clicks than competitors' ads, so your Quality Score increases — even if your bid is lower.

4. How is Google Ads bidding? 

Answer:

Google Ads follows an auction system, where businesses bid on keywords. But it is not the highest bidder who gets chosen. Rather, Google takes into consideration:

Your bid amount

Quality Score

The expected effect of ad extensions

The outcome is Ad Rank, which decides your ad's position.

Real Tip: From Uncodemy’s mock tests, many learners discover that smart bidding strategies (like Target CPA or Maximize Conversions) often perform better than manual bidding.

5. What is CTR and how is it calculated?

Answer:

CTR (Click-Through Rate) = (Number of Clicks / Number of Impressions) x 100

Example:

If your ad had 500 impressions and 25 clicks, the CTR is:

(25 ÷ 500) x 100 = 5%

A higher CTR often means your ad is relevant to your audience.

6. What are Ad Extensions? Why are they important?

Answer:

Ad Extensions are additional pieces of information (like phone numbers, site links, location, etc.) that appear with your ad to make it more useful and clickable.

Types:

Sitelink Extensions

Call Extensions

Location Extensions

Callout Extensions

Structured Snippets

Benefits:

Improve ad visibility

Increase CTR

Better Ad Rank

In Uncodemy’s course, you’ll practice setting up all types of extensions with real accounts.

7. SEO vs. Google Ads?

Answer:

Feature\tSEO\tGoogle Ads

Cost\tOrganic (Free)\tPaid (per click)

Time to Results\tTakes time\tInstant visibility

Placement\tBelow paid ads\tAbove organic results

Control\tLimited\tFull control of budget & targeting

They complement one another in a harmonious digital marketing plan.

8. What is Conversion Tracking and how do I set it up?

Answer:

Conversion Tracking enables you to track what occurs after a user clicks your ad—e.g., purchases, sign-ups, or downloads.

Steps to set up:

Go to Tools > Conversions in Google Ads.

Select a conversion source (Website, App, Phone calls, etc.)

Set up the conversion action.

Place the conversion tracking tag on your site.

Uncodemy offers demo sites where you can actually place tags and monitor test conversions.

9. Why is Landing Page important in Google Ads?

Answer:

An optimized landing page:

Boosts Quality Score

Boosts conversions

Decreases bounce rate

Tips:

Use clean CTA (Call-to-Action)

Stay relevant to the ad

Ensure quick loading and mobile-friendliness

Example:

If your ad is for "Buy Running Shoes," don't direct users to your homepage. Direct them to the running shoes product page.

10. How do you conduct Keyword Research for Google Ads?

Answer:

Keyword research forms the core of a good campaign. Use tools such as:

Google Keyword Planner

Ubersuggest

SEMrush

Ahrefs

Keyword types:

Broad Match

Phrase Match

Exact Match

Negative Keywords

Uncodemy educates learners in creating keyword lists and structuring ad groups efficiently.

11. What are Negative Keywords in Google Ads?

Answer:

Negative keywords stop your ads from appearing in irrelevant searches.

Example:

If you're selling luxury watches, you could include "cheap" or "free" as negative keywords to prevent wasteful clicks.

This means your ad spend gets invested in high-intent users.

12. Define the term Remarketing in Google Ads.

Answer:

Remarketing enables you to display ads to individuals who have visited your website or engaged with your app earlier.

Types:

Standard Remarketing

Dynamic Remarketing

Video Remarketing

Real Use Case:

E-commerce websites utilize remarketing to display product ads for users who left carts.

Pro Tip from Uncodemy: Always limit remarketing ad frequency to prevent user annoyance.

13. How do you enhance the performance of a poor-performing campaign?

Answer:

Optimize keywords and match types

Apply A/B testing on ad copies

Optimize landing pages

Rigorously adjust bidding strategies

Include ad extensions

Competitor ad analysis

Uncodemy offers real-life case studies to enable learners to troubleshoot and also optimize live campaigns.

14. What is Google Ads Editor?

Answer:

Google Ads Editor is a free, downloadable software by Google, enabling offline bulk editing of campaigns.

Benefits:

Make bulk edits quicker

Work offline and sync later

Easily duplicate campaigns or ad groups

15. What are Smart Campaigns?

Answer:

Smart Campaigns are automatic campaigns most suitable for small businesses or new users. Google takes care of targeting, bidding, and ad placement.

Note: Although easy, Smart Campaigns provide less control than regular campaigns. Uncodemy suggests mastering both for interview purposes.
