Question 1

Walk me through a paid campaign you ran from start to finish.

Accepted Answer

It's the fastest way to tell whether you built campaigns yourself or sat near someone who did. Name the goal and the conversion you optimised for, not just the channel Describe the setup choices: audiences or keywords, bidding strategy, budget split, creative Say what the early data showed and what you changed because of it Finish with the result and one thing you'd do differently next time

Question 2

Cost per lead jumped this week. How do you work out why?

Accepted Answer

This happens constantly, and they want to see whether you check the boring causes before guessing. Confirm tracking first: are conversions still recording in the platform and in the CRM Split the change into cost per click and conversion rate to see which one moved Check auction insights, recent edits in the change history and landing page changes Say how you'd report it to your manager before you have the full answer

Question 3

How do you set up tracking for a new landing page?

Accepted Answer

Broken tracking ruins every report downstream, and many candidates have never set it up themselves. Define the conversion event with the team first, such as a form submit or a booked demo Set it up in Google Tag Manager with a clear trigger and test it in preview mode Confirm it arrives in Google Analytics and in each ad platform Use consistent UTM parameters so traffic sources match in the CRM

Question 4

How would you split a fixed budget across search, social and email?

Accepted Answer

They want to see whether you think in terms of intent and cost per result, or just spread money evenly. Start from where buyers with intent already are, often branded and high-intent search Use social for reach and retargeting, with a clear way to judge it Treat email as the cheapest channel for people already on the list Hold back a small test budget and move money on results, not habit

Question 5

Tell me about an A/B test you ran. What did you learn?

Accepted Answer

Testing discipline separates specialists who guess from ones who learn. State the single thing you changed and why you expected it to matter Explain how long you let it run and how you decided you had enough data Give the result honestly, including a test that lost Say what you rolled out or tested next because of it

Question 6

How do you decide which audiences to target on Meta or LinkedIn?

Accepted Answer

Audience choices drive most of the cost on social, and they want to hear real options, not vague personas. Start with first-party lists: customers, email subscribers, site visitors Build lookalike or matched audiences from your best customers, not all of them Use job title or interest targeting when the list is too small Exclude current customers and recent converters so you don't pay to reach them again

Question 7

What does good SEO work look like for someone in your role?

Accepted Answer

Many teams expect the digital specialist to cover organic search alongside paid, even if it isn't in the title. Use Google Search Console to find pages that get impressions but few clicks Rewrite titles and meta descriptions for those pages and track the change Work with the content writer on keyword research using a tool like Semrush or Ahrefs Flag technical problems like broken redirects to the web team

Question 8

Which email metrics do you watch, and which do you ignore?

Accepted Answer

Email reporting got noisier as open tracking became less reliable, and they want to know you've noticed. Treat open rates with caution because privacy features inflate them Focus on clicks, conversions and revenue or leads per send Watch unsubscribes and spam complaints as signs the list is tired Mention segmenting by behaviour rather than sending everything to everyone

Question 9

Tell me about a campaign that failed.

Accepted Answer

Every specialist has one, and how you talk about it shows whether you learn or deflect. Pick a real miss with a clear cause you can explain Own your part of it, even if other things contributed Say how quickly you spotted it and what you paused or changed Name the habit you changed afterward

Question 10

How do you explain results to people who don't live in the ad platforms?

Accepted Answer

You'll report to managers and sales leaders who care about leads and revenue, not click-through rate. Lead with the business outcome: leads, sales, cost per customer Keep a short dashboard in Looker Studio or a spreadsheet that people can check themselves Explain the main reasons behind the number in plain words End with the next action and what you need from them

Question 11

How do you keep up with changes to the platforms?

Accepted Answer

Ad platforms change settings and policies often, and a specialist who stops learning falls behind quickly. Name specific habits, such as reading platform release notes or following a few practitioners Give an example of a change you adapted to in a live account Mention testing new features on a small budget before rolling them out
