What is the difference between SEO and SEM?

SEO earns unpaid (organic) traffic by improving rankings; SEM usually means paid search ads. Explain that SEO is slower but compounds, while ads give instant visibility at a cost per click.

What are the most important on-page SEO factors?

Title tag, meta description, headings, content that matches search intent, internal links, page speed and mobile-friendliness. Mention that keyword stuffing hurts rather than helps.

How does Google Ads decide which ad to show?

Ad Rank = bid × Quality Score (expected click-through rate, ad relevance, landing page experience). A higher-quality ad can beat a higher bid — that's the insight interviewers want.

What are CAC and LTV, and why do they matter together?

CAC is what you spend to acquire one customer; LTV is the revenue that customer generates over their lifetime. A business is healthy when LTV is comfortably higher than CAC — commonly 3x or more.

A campaign has many clicks but no conversions. What do you check?

Check the landing page first (speed, message match with the ad, clear call to action), then targeting (wrong audience or keywords), then tracking (is the conversion pixel even firing?). Show a logical debugging order.

How would you track whether a campaign is working?

Set up conversion tracking (GA4, UTM parameters, ad platform pixels), define one primary KPI before launch, and review weekly: spend, clicks, CTR, conversions and cost per conversion.

What is a good click-through rate?

Avoid one magic number — it depends on channel and industry. Search ads often see 3–5%, display under 1%. Say you'd benchmark against the account's own history and industry averages.

Have you run any campaign or page yourself? What were the results?

Real experience beats certificates: a college fest page, a friend's business, your own Instagram or blog. Share numbers — reach, followers gained, budget spent — and one thing you'd do differently.
