✍️ Sample SEM Questions & Answers
1. Which of the following attribution models assigns 100% of the conversion credit to the very first ad or channel a user interacted with on their path to conversion?
The First-Click attribution model gives full credit for a conversion to the first touchpoint a customer had with the brand. It is useful for understanding which channels are most effective at initiating the customer journey.
2. Search engines get submissions for mirror sites.
Search engines generally do not receive or accept direct submissions for mirror sites. In fact, creating exact duplicates (mirror sites) can be detrimental to SEO, as search engines often penalize duplicate content. The goal is to have unique, valuable content, and if a mirror site is used, it typically needs to be handled carefully with canonical tags or other methods to indicate the preferred version to search engines, rather than submitting it as a separate entity.
3. Which optimization lever should you adjust first when your Search Impression Share is high but conversion rate is low?
High impression share with low CVR indicates the ad is being seen but not compelling users to convert, so improving ad copy and landing page alignment is the priority.
4. What does 'Bounce Rate' indicate when analyzed alongside SEM campaign data?
Bounce rate measures single-page sessions — high bounce rate from SEM traffic may indicate a landing page relevance or experience problem.
5. What happens if we don't use the client's budget for SEM advertisements in a particular month?
In many SEM service agreements, unspent client budget from one month is typically rolled over to the next. This ensures that the client's investment is fully utilized for their advertising campaigns over time, maximizing their potential reach and results. It prevents the loss of funds and allows for flexibility in campaign spending based on performance and market conditions.
6. A campaign's ROAS is 400%. If ad spend is $5,000, what is the conversion revenue?
ROAS = Revenue ÷ Ad Spend × 100, so Revenue = ROAS% × Spend = 4.0 × $5,000 = $20,000.
