Technical PPC Questions

Technical PPC (Pay-Per-Click) interview questions often delve into specific skills, platforms, and scenarios that PPC professional’s encounter. Below are technical PPC interview questions along with structured answers that demonstrate expertise and analytical thinking:

1. Explain the process of conducting a PPC audit.

• Answer: A PPC audit involves a comprehensive review of an account’s settings, structure, and performance. I begin by evaluating the account structure, reviewing campaign settings for target locations, devices, and ad schedules. Then, I analyse the keyword strategy, assess ad copy and creatives, and inspect landing pages for alignment with campaign goals. I also scrutinize the quality scores and bid strategies. Throughout, I look for discrepancies, wasted spend, or areas for optimization.

• Answer: To optimize a shopping campaign, I ensure the product feed is detailed and up-to-date, including high-quality images and accurate product information. I use negative keywords to filter irrelevant traffic, adjust bids based on performance metrics, segment products into appropriate product groups, and utilize smart bidding for conversion optimization. Additionally, I analyze the performance data to identify trends and adjust strategies accordingly.

 

5. What are the best practices for using match types in PPC?

• Answer: Best practices for using match types include using broad match for keyword discovery, modified broad match for a balance between reach and relevance, phrase match for more control, and exact match for targeting specific queries. It’s also important to continuously review search query reports to add negative keywords and refine the match type strategy.

 

6. Explain how to set up and measure a remarketing campaign.

• Answer: To set up a remarketing campaign, I create audience lists based on users who have interacted with the website. I then design targeted ad creatives and decide on the placement and bidding strategy. To measure its effectiveness, I track metrics such as view-through conversions, click-through conversions, and return on ad spend (ROAS).

 

7. How do you handle ad testing and optimization?

• Answer: For ad testing, I use A/B testing (split testing) to compare different versions of ads. I change one element at a time, such as headlines, descriptions, or calls to action. I measure performance based on CTR, conversion rate, and Quality Score, and I give each test sufficient time to collect actionable data before making decisions.

 

8. What approach do you take to international PPC campaigns?

Then, I ensure conversions are correctly categorized, and I monitor the data to refine PPC strategies continually.

These answers illustrate the deep technical understanding necessary for advanced PPC management.

 

Situational Questions

1. If a client’s PPC campaign is not generating the expected ROI despite having a high CTR, what steps would you take to address this?.

• Answer: A high CTR with a low ROI suggests that while the ads are relevant, they may not be reaching the right stage of the buyer’s journey, or the landing page is not effectively converting. I would analyze the conversion funnel, assess the landing page for messaging and usability, and ensure the call to action is clear. I would also examine the audience targeting to make sure we’re reaching potential customers with a higher intent to purchase.

 

2. How would you handle a sudden drop in traffic from a PPC campaign that has consistently performed well?

• Answer: I would first check for any recent changes in the account, such as budget caps, bid adjustments, or paused campaigns. Next, I would review the Search Terms report to see if search behavior has changed. I would also check for external factors like increased competition or shifts in market demand. Based on these findings, I would adjust the strategy to regain traffic, which might include bid optimization, budget reallocation, or revising the ad copy.

 

3. A client wants to increase their ad visibility on a limited budget, how would you achieve this?

• Answer: To increase ad visibility on a limited budget, I would focus on improving the Quality Scores by optimizing ad relevance and landing page experience, which can lead to a better ad position for a lower cost. I would also suggest using dayparting to run ads during peak performance times and implementing targeted remarketing campaigns to re-engage visitors.

 

4. If you noticed that a particular keyword was spending a lot of the budget but not converting, what would be your course of action?

• Answer: If a keyword is not converting despite high spend, I would first analyze the search query report to understand the context of the clicks. If the keyword is too broad or attracting irrelevant traffic, I would add negative keywords or adjust the match type to be more specific. If the keyword is relevant but still not converting, I would evaluate and test different ad copies and landing pages to improve the conversion rate.

 

5. You’re tasked with reducing the cost-per-acquisition (CPA) for a campaign, where would you start?

• Answer: To reduce CPA, I would begin by identifying and pausing underperforming keywords and ads. I would then optimize the campaign’s bidding strategy, perhaps switching to manual bidding for greater control. Additionally, I would work on improving the Quality Score by refining the ad copy and landing pages, and I would test different targeting options to focus on the most profitable segments.

 

Remarketing Questions on PPC

Remarketing PPC interview questions evaluate your expertise in engaging users who have previously interacted with a brand. Here are five such questions with answers:

1. What is remarketing and why is it a valuable strategy?

• Answer: Remarketing is a strategy that targets individuals who have previously visited your website but did not make a purchase or complete a desired action.

2. How would you segment your remarketing audiences to ensure the ads are relevant?

4. What strategies would you employ to avoid ad fatigue in your remarketing campaigns?

• Answer: To avoid ad fatigue, I would implement frequency capping to limit how often ads are shown to the same user. I would also create dynamic ads that automatically adjust the content based on the user’s past interactions and regularly update the creative to keep the messaging fresh.

 

5. How do you measure the success of a remarketing campaign?

• Answer: Success in remarketing is measured by the increase in conversion rates and overall ROI. I track metrics like view-through conversions, click-through conversions, time to conversion, and the number of times users re-engage with the ads. It’s also important to assess the cost-per-acquisition to ensure the remarketing efforts are cost-effective.

By preparing answers that include specific examples and demonstrate a clear understanding of PPC strategies, you can show potential employers that you’re capable of handling real-world PPC challenges effectively.

I also make sure that landing pages are transparent, particularly in terms of business practices, data collection, and user privacy.

 

2. What steps do you take if your ad gets disapproved for policy violations?

5. How do you balance automation with manual intervention in PPC?

• Answer: While automation is powerful for managing campaigns at scale, manual intervention is crucial for strategy and oversight. I use automation for bid adjustments, rule-based tasks, and repetitive processes but rely on manual intervention for strategic decisions, creative development, and performance reviews.

By targeting customers with a high LTV, we can optimize campaigns for long-term profitability rather than short-term gains.

 

8. How do you use PPC data to influence broader marketing strategies?
