Digital Marketing Interview Question Bank — Basic to Advanced (2026)

103 questions with answers across four domains: SEO, Google Ads, Meta Ads and Social Media Marketing.

Every question carries a level tag:

[B] Basic — a fresher should answer without hesitation.
[I] Intermediate — answer plus the reason behind it.
[A] Advanced — judgment, trade-offs, or diagnosis.
[S] Situation — no single correct answer; the reasoning is the answer.

All platform facts are current as of September 2026. This field changes faster than any other in the question bank, so re-verify the platform-specific answers every six months.

Corrections to the Existing Sheets

These errors circulate in commonly shared study sheets and are being taught to students. Fix these first — a wrong answer taught confidently is worse than no answer.

Where	What It Says	What Is Correct
SEO Q2	"ALL text"	ALT text (alternative text)
SEO Q4	"Keyword match types in SEO — short-tail and long-tail"	Match types (broad, phrase, exact) are a paid search concept. Short-tail and long-tail are keyword types. The question is mislabelled — split it into two.
SEO Q9	"Most important on-page factors focus on user experience and relevance"	That is not an answer. Needs the actual list: title tag, H1, content depth, internal links, URL, ALT text, page speed.
Google Ads	Numbering jumps 1 → 3	Question 2 is missing from the sheet.
Google Ads Q8	"Ad Rank = Bid × Quality Score"	Outdated. Ad Rank now uses six factors: bid, ad and landing page quality, Ad Rank thresholds, auction context, expected impact of assets and formats, and search context.
Google Ads Q9	"Search, Display, Video, Shopping, App, PMax"	2026 list adds Demand Gen and Local, plus AI Max for Search. Display is being absorbed into Demand Gen.
Google Ads situation	"I have run a Meta campaign…"	Wrong document — this is the Meta question pasted into the Google Ads sheet.
Meta Q1	"Facebook, Twitter, Ads, AB Testing ad, campaigns"	Twitter is not a Meta platform. Correct: Facebook, Instagram, Messenger, Audience Network, Threads.
Meta Q3	Question asks how long to run ads; answer explains how long to learn them	Two different questions. Split them.
Meta Q9	Objectives list includes "Local Store Visits & Promotions"	That is a Google Ads objective. Meta has exactly six: Awareness, Traffic, Engagement, Leads, App Promotion, Sales.
Meta Q10	"Business clarity, Campaign, Ad Set, Ad, billings"	Meta ad structure has three levels: Campaign → Ad Set → Ad.
Meta Q8	"Minimum ROAS"	The correct name is ROAS goal. Also missing Highest Volume / Highest Value.
Google Ads + Meta	Identical situation question in both sheets	Duplicate — keep it in Meta, write a Google-specific one.
All four	Google search links pasted into answers	Clean these out before the sheets go to students.

Part 1 — SEO (28 Questions)

Basic

Q1 · Basic

What is SEO?

Optimising a website so it appears for relevant queries in unpaid search results. The goal is qualified traffic, not traffic.

Q2 · Basic

What are the three types of SEO?

On-page (content, titles, internal links), off-page (backlinks, mentions, brand signals), and technical (crawling, indexing, speed, structure).

Q3 · Basic

Difference between on-page and off-page SEO?

On-page is everything you control on your own site. Off-page is what happens elsewhere that influences your authority — mainly backlinks and brand mentions.

Q4 · Basic

What is a meta description?

A summary shown under the title in search results, roughly 150-160 characters. It is not a ranking factor; it affects click-through rate, and Google frequently rewrites it.

Q5 · Basic

What is ALT text?

Descriptive text for an image, used by screen readers and by search engines that cannot see the image. Describe the image; do not stuff keywords.

Q6 · Basic

What is a sitemap?

An XML file listing the pages you want crawled. It helps discovery on large or poorly linked sites — it does not guarantee indexing.

Q7 · Basic

What is robots.txt, and how is it different from noindex?

robots.txt controls crawling; noindex controls indexing. Blocking a page in robots.txt means Google cannot read the noindex tag, so a blocked page can still appear in results. This distinction is asked constantly.

Q8 · Basic

What is a backlink?

A link from another site to yours, treated as a signal of credibility. Relevance and authority of the linking site matter far more than the count.

Q9 · Basic

Dofollow vs nofollow?

Dofollow passes ranking signal. Nofollow tells search engines you do not endorse the link — used for paid, user-generated and untrusted links. Related attributes: rel="sponsored" and rel="ugc".

Q10 · Basic

What is a broken link?

A link pointing to a page that no longer exists, returning a 404. It wastes crawl budget and hurts user experience; fix with a 301 redirect or by removing the link.

Intermediate

Q11 · Intermediate

What are short-tail and long-tail keywords?

Short-tail are broad, high-volume, high-competition, vague intent ("shoes"). Long-tail are specific, lower-volume, clearer intent, easier to rank ("running shoes for flat feet under 3000"). Freshers should target long-tail first.

Q12 · Intermediate

What are the most important on-page factors?

Title tag with the primary keyword near the front, one clear H1, content that satisfies the query fully, descriptive URL, internal links to related pages, ALT text, and page speed. In that order of impact.

Q13 · Intermediate

What is search intent, and what are its four types?

What the user actually wants: informational, navigational, commercial (comparing before buying), and transactional. Matching the wrong intent is the most common reason a well-optimised page does not rank — a product page will not beat a guide for a "how to" query.

Q14 · Intermediate

What are canonical tags for?

Telling Google which version of duplicate or near-duplicate pages is the original, so ranking signals consolidate on one URL. Common on e-commerce sites with filters and sorting parameters.

Q15 · Intermediate

301 vs 302 redirect?

301 is permanent and passes ranking signals. 302 is temporary. Using 302 for a permanent move is a common mistake that leaves the old URL indexed.

Q16 · Intermediate

What are Core Web Vitals, and what are the current thresholds?

Real-user performance metrics: LCP ≤ 2.5s (loading), INP ≤ 200ms (responsiveness — replaced FID in 2024), CLS ≤ 0.1 (visual stability). Use field data from Search Console, not just lab scores from a speed tool.

Q17 · Intermediate

What is E-E-A-T?

Experience, Expertise, Authoritativeness, Trustworthiness — the framework Google's quality raters use. Not a direct ranking score, but it shapes what the algorithm rewards, and it matters most for health, finance and legal content.

Q18 · Intermediate

What is schema markup, and does it improve rankings?

Structured data in JSON-LD that tells search engines what your content is. It is not a direct ranking factor, but it enables rich results, which lift click-through rate, and it helps AI systems understand and cite your page.

Advanced

Q19 · Advanced

What are AI Overviews, and how have they changed SEO?

AI-generated summaries at the top of results that answer the query directly, with citations. The consequence: ranking first no longer guarantees the click, because a large share of searches now end without one. The objective shifts from ranking on the page to being cited in the answer.

Q20 · Advanced

What is GEO / AEO, and how is it different from SEO?

Generative Engine Optimisation (also called Answer Engine Optimisation) is optimising to be cited inside AI-generated answers rather than to rank in blue links. Practically: answer the question directly in the first 100 words of each section, use self-contained extractable passages, keep facts about your brand consistent across the web, and make content readable without JavaScript.

Q21 · Advanced

Traffic dropped 40% overnight. Walk me through your diagnosis.

Check in order: Search Console for a manual action, then indexing (did a noindex or robots.txt change ship?), then whether it is one page or sitewide, then whether it coincides with a known core update, then whether a redirect or migration broke, then whether an AI Overview now occupies the query. Sitewide and overnight usually means technical or penalty, not content.

Q22 · Advanced

How do you decide whether a page should be a new page or a section of an existing one?

By search intent. If the same query set is served, keep one strong page — splitting causes keyword cannibalisation where two of your pages compete and both rank worse. If the intent is genuinely different, create a new page.

Q23 · Advanced

How do you audit a backlink profile?

Look at referring domains rather than total links, relevance of linking sites, anchor text distribution (over-optimised exact-match anchors are a risk signal), and the ratio of dofollow to nofollow. Disavow only for clearly manipulative patterns — Google mostly ignores bad links now, and unnecessary disavowing does damage.

Q24 · Advanced

What is crawl budget, and when does it actually matter?

The crawling capacity Google allocates to your site. It only matters at scale — large e-commerce or news sites with tens of thousands of URLs. On a 50-page site it is irrelevant, and a candidate who raises it for a small site is repeating something they read.

Situation-Based

Q25 · Situation

A new client wants to rank on page one in one month. How do you respond?

Explain the honest timeline — new sites and competitive terms typically take months — then reframe: pick low-competition long-tail terms where progress is realistic, fix technical blockers, and set expectations against leading indicators like impressions and indexed pages rather than position alone. Promising a one-month ranking is how agencies lose clients in month three.

Q26 · Situation

How does SEM indirectly help SEO?

Paid search gives you keyword and conversion data before you invest months in content, lets you test titles and messaging for click-through rate, increases branded searches which correlate with organic strength, and validates which offers convert. It buys you data, not rankings.

Q27 · Situation

The client's website is beautiful but ranks nowhere. Where do you start?

Check whether it can be crawled and indexed at all — a design-first site often ships with content inside images, JavaScript-rendered text, missing H1s, and no unique title tags. Beauty and crawlability fail independently.

Q28 · Situation

A competitor with weaker content outranks you. What do you check?

Backlink authority, site age and topical authority, search intent match, page experience, and whether their page structure is more extractable. "Better content" that does not answer the query as directly as the competitor is not better content for that query.

Part 2 — Google Ads (26 Questions)

Basic

Q29 · Basic

What are the Google Ads campaign objectives?

Sales, Leads, Website traffic, Awareness and reach, App promotion, Local store visits and promotions, and Product and brand consideration.

Q30 · Basic

What are the campaign types in 2026?

Search, Performance Max, Shopping, Demand Gen, Video, App, and Local — plus AI Max for Search. Display is being absorbed into Demand Gen, and Dynamic Search Ads are being upgraded to AI Max.

Q31 · Basic

Reach vs impressions?

Reach is unique users who saw the ad. Impressions is how many times it was shown. Impressions are always equal to or greater than reach.

Q32 · Basic

What is CPC, CPM, CPL and ROAS?

CPC = spend ÷ clicks. CPM = (spend ÷ impressions) × 1000. CPL = spend ÷ leads. ROAS = revenue ÷ ad spend.

Q33 · Basic

What is the CTR formula?

CTR = (clicks ÷ impressions) × 100.

Q34 · Basic

What are the keyword match types?

Broad, phrase and exact. Modified broad match was retired in 2021 — if a candidate lists four, that is a dated answer.

Q35 · Basic

What are negative keywords?

Terms that stop your ad from showing. They are the single cheapest optimisation in a search account, and the first thing to check when leads are poor quality.

Q36 · Basic

What is Quality Score and what is its range?

A 1-10 diagnostic of how relevant your ad is to the query, made of expected CTR, ad relevance and landing page experience. It is a diagnostic, not a live auction input.

Q37 · Basic

What is a conversion, and how is it tracked?

A defined valuable action — purchase, form submit, call. Tracked with a Google tag or through GA4 imports. Without conversion tracking, smart bidding has nothing to optimise toward, which is the most common reason an account underperforms.

Intermediate

Q38 · Intermediate

What is Ad Rank, and how is it calculated?

The score deciding whether your ad shows and in what position. It uses six factors: your bid, ad and landing page quality, Ad Rank thresholds, the context of the search, the expected impact of assets and formats, and competitiveness of the auction. The old "bid × Quality Score" formula is a simplification that no longer holds.

Q39 · Intermediate

What are the main bidding strategies?

Manual CPC, Maximise clicks, Maximise conversions, Maximise conversion value, Target CPA and Target ROAS. Smart bidding needs conversion volume — target strategies on an account with five conversions a month will not work.

Q40 · Intermediate

What is a Responsive Search Ad?

The standard search format: up to 15 headlines and 4 descriptions that Google combines and tests. Pin sparingly — pinning everything removes the machine's ability to test and usually lowers performance.

Q41 · Intermediate

What is Performance Max, and when should you not use it?

One campaign running across Search, Shopping, YouTube, Display, Gmail, Discover and Maps, with Google choosing placement and bid. Do not use it without solid conversion tracking and enough conversion volume to learn from — without those it spends broadly and reports little.

Q42 · Intermediate

What is the difference between Search and Display intent?

Search captures existing demand — the user is looking. Display and Demand Gen create demand — the user is not. Judging a Display campaign by search-campaign conversion rates is a category error.

Q43 · Intermediate

What is impression share, and what do the 'lost' metrics tell you?

The share of available impressions you received. Lost IS (budget) means you are under-funded; lost IS (rank) means your Ad Rank is too low. These two numbers tell you whether to add budget or fix relevance — a very common interview question.

Q44 · Intermediate

What is a landing page experience, and why does it matter for cost?

How relevant, fast and usable your page is for the query. It feeds Ad Rank, so a better page can win a higher position at a lower CPC than a competitor bidding more. This is how a smaller advertiser beats a bigger one.

Q45 · Intermediate

What are audience signals, and are they targeting?

In Performance Max and Demand Gen, signals are a starting hint for the AI, not a hard restriction — the system can go beyond them. Confusing signals with targeting is a common mistake.

Advanced

Q46 · Advanced

Your CPC is rising and conversions are flat. What do you check, in order?

Search terms report for irrelevant traffic, then match types that may have loosened, then negative keyword coverage, then Quality Score components, then auction insights for a new competitor, then whether the landing page or the offer changed. Raising the bid is the last option, not the first.

Q47 · Advanced

How do you structure a search account for a business with three services?

One campaign per service so budget cannot bleed between them, tight ad groups by intent within each, negative keywords cross-applied between campaigns, and a separate brand campaign. Structure is a budget-control decision more than a relevance one.

Q48 · Advanced

When would you choose Search over Performance Max, and why?

When you need control and transparency: search term visibility, negative keyword control, and knowing which query drove which conversion. PMax trades that control for reach and automation. For a lead-gen business where lead quality matters more than volume, that trade is often wrong.

Q49 · Advanced

How do you measure whether Google Ads is actually profitable?

Against a business number, not a platform number — cost per qualified lead or contribution margin, not cost per click or platform-reported conversions. Platform attribution counts the assist as the cause; the CRM tells you what actually closed.

Q50 · Advanced

What is attribution, and why do Google and Meta both claim the same conversion?

Each platform attributes conversions it touched within its own window, so summing platform reports double counts. Reconcile against one source of truth — GA4 or the CRM — and use platform numbers for optimisation, not for reporting revenue.

Q51 · Advanced

AI is taking over campaign management. What does the marketer still do?

Feeds the system: conversion tracking accuracy, conversion value definition, creative and asset quality, offer, landing page, and negative keyword hygiene. The auction is automated; the inputs are not, and bad inputs automate faster failure.

Situation-Based

Q52 · Situation

Your Search campaign is getting clicks but no conversions. Diagnose it.

Split the funnel: is the traffic wrong (search terms report), or is the page failing (bounce, load time, form friction), or is tracking broken (fire a test conversion first)? Check tracking before concluding anything — a large share of 'no conversions' cases are measurement failures.

Q53 · Situation

The client says "our competitor's ad is always above ours." What do you say?

Position is decided by Ad Rank, not budget alone, so the answer may be relevance rather than money. Show auction insights, check Quality Score components, and reframe the goal from position to cost per acquisition — being second at half the CPC is usually the better business outcome.

Q54 · Situation

A client with ₹10,000/month budget wants Search, Display and YouTube all running.

Refuse politely and explain the arithmetic: split three ways, no channel gets enough data to exit learning, so all three underperform. Put the whole budget on the highest-intent channel, prove a return, then expand.

Part 3 — Meta Ads (26 Questions)

Basic

Q55 · Basic

Which platforms do Meta ads run on?

Facebook, Instagram, Messenger, Threads and the Audience Network. Twitter/X and LinkedIn are separate companies and separate ad platforms.

Q56 · Basic

What are the six Meta campaign objectives?

Awareness, Traffic, Engagement, Leads, App Promotion, and Sales. Exactly six — no more.

Q57 · Basic

What is the Meta ad structure?

Three levels. Campaign sets the objective and often the budget. Ad Set holds audience, placements, schedule and budget. Ad holds the creative and copy.

Q58 · Basic

What is the Meta Pixel?

A JavaScript snippet on your website that reports user actions back to Meta for tracking, optimisation and audience building.

Q59 · Basic

What is the Conversions API, and why does it matter?

A server-side connection that sends events directly from your server to Meta. It matters because browser-based pixel tracking has been degraded by iOS privacy changes and ad blockers — running Pixel plus CAPI together recovers a meaningful share of lost signal. This is now a standard question and most freshers cannot answer it.

Q60 · Basic

What is a Custom Audience?

An audience built from your own data — website visitors, customer list, app users, or people who engaged with your page or content.

Q61 · Basic

What is a Lookalike Audience?

An audience Meta builds resembling a source Custom Audience. Quality depends entirely on the source: a lookalike from 100 random visitors is worthless; one from 1,000 actual purchasers is strong.

Q62 · Basic

What is A/B testing?

Running two versions with one variable changed to see which performs better, with the audience split so results are not contaminated. Changing three things at once tells you nothing about which one worked.

Q63 · Basic

What KPIs do you read after a campaign runs?

Reach, impressions, frequency, CTR, CPC, CPM, cost per result, conversions and ROAS. Which one matters depends on the objective — judging an Awareness campaign by cost per lead is judging the wrong thing.

Intermediate

Q64 · Intermediate

What is the learning phase, and how do you exit it?

The period where Meta's delivery system is still learning who converts. It typically exits at around 50 optimisation events in 7 days per ad set. Editing budget, creative or audience resets it — which is why constant tweaking keeps campaigns permanently stuck.

Q65 · Intermediate

How long should you run a campaign before judging it?

Long enough to exit learning and accumulate meaningful data — typically 7 to 14 days minimum before structural changes. Killing an ad set on day two is reading noise.

Q66 · Intermediate

What are the Meta bidding strategies?

Highest Volume and Highest Value (automatic), Cost per Result Goal (cost cap), Bid Cap, and ROAS Goal. Automatic is the default and usually correct until you have a proven cost target.

Q67 · Intermediate

What is Advantage+, and what changed in 2026?

Meta's AI automation layer for audience, placement, creative and budget. In early 2026 Meta merged the manual and Advantage+ creation flows into one interface, making AI optimisation the default for new campaigns across Sales, Leads and App objectives.

Q68 · Intermediate

What is Advantage+ Audience, and how has targeting changed?

Detailed targeting now works as a suggestion rather than a hard boundary — the system can deliver outside your stated interests if it finds better converters. Meta retired detailed-targeting exclusions in 2025, so exclusions must now be done with Custom Audiences.

Q69 · Intermediate

What is frequency, and what number is a warning?

Average times one person saw your ad. Rising frequency alongside falling CTR and rising CPM is creative fatigue. The fix is new creative, not a bigger budget.

Q70 · Intermediate

CBO vs ABO — when do you use each?

Campaign Budget Optimisation lets Meta distribute budget across ad sets; Ad Set Budget Optimisation gives you manual control per ad set. Use ABO when testing so each variant gets a fair spend, and CBO when scaling a proven winner.

Q71 · Intermediate

What is a hook, and why does it decide performance?

The first 2-3 seconds of a video or the first line of copy. In a feed the user scrolls in under a second, so the hook determines whether anything else you made is seen at all. It is the highest-leverage element in the whole ad.

Advanced

Q72 · Advanced

Cost per lead is good but the sales team says the leads are junk. What do you do?

Optimise for a deeper event, not the form fill — a qualified lead sent back through the Conversions API, or a scheduled call. Also add friction deliberately: a qualifying question or a higher-intent form reduces volume and raises quality. Cheap leads and good leads are different objectives, and the algorithm optimises for whatever you told it.

Q73 · Advanced

Why do Meta-reported conversions and your CRM numbers not match?

Different attribution windows, view-through attribution counted by Meta, cross-device matching, and post-iOS signal loss. Meta's reported numbers are directionally useful for optimisation and unreliable as revenue reporting. Use blended metrics against total business revenue.

Q74 · Advanced

How do you scale a winning campaign without breaking it?

Increase budget in steps rather than doubling, which resets learning. Alternatively duplicate into a broader audience, or scale horizontally with new creative against the same audience. Sudden large increases push the campaign back into learning and performance drops for days.

Q75 · Advanced

Ad set A and ad set B have overlapping audiences. What is the problem?

Audience overlap means you bid against yourself in the same auction, raising your own CPM. Consolidate ad sets or exclude one from the other.

Q76 · Advanced

Your creative worked for three weeks and is now dying. What is happening?

Creative fatigue in a saturated audience — frequency up, CTR down, CPM up. In 2026 creative volume is the scaling lever, not budget: plan a production pipeline rather than a single hero asset.

Q77 · Advanced

What signals actually drive delivery quality now?

Clean first-party data: Pixel plus Conversions API, enough weekly conversion events for the system to learn, accurate event values, and creative variety for the system to test. With automation handling targeting, your competitive advantage moved to signal quality and creative.

Situation-Based

Q78 · Situation

You ran a Meta campaign and are not getting quality leads. What do you check?

In order: which event you optimised for, audience definition and geography, the offer and its clarity, creative and hook, form friction and whether qualifying questions exist, landing page match with the ad, lead follow-up speed, and finally whether tracking is even firing correctly. Most junk-lead problems are optimisation-event problems, not targeting problems.

Q79 · Situation

The client wants to boost a post instead of running an ads-manager campaign.

Explain what boosting gives up: objective choice, ad set structure, placement control, proper conversion optimisation and reporting. Boosting is fine for engagement on organic content; it is the wrong tool for leads or sales.

Q80 · Situation

A campaign performed brilliantly last month and is failing this month with no changes made.

Nothing stays constant: audience saturation, seasonality, competitor spend raising auction prices, creative fatigue, or a tracking break. Check frequency and CPM first — a rising CPM with stable CTR usually means auction competition, while a falling CTR means the creative.

How to Use This Bank

For a fresher assessment, ask the [B] questions and expect fluency. For a 1-2 year candidate, [B] and [I], and probe one level deeper on every answer — "why" is where memorised answers fall apart. For anyone claiming to run accounts, spend most of the time on [A] and [S], because those cannot be prepared from a PDF.

The strongest single filter across all four domains: ask the candidate to describe a campaign or page that failed and what they changed. Anyone who has actually run campaigns has that story ready. Anyone who has only studied them does not. Build that muscle with timed mock interviews at Roundexa.com.
