Performance Marketing FAQs

The Complete FAQ Guide for Founders and Marketers

Performance marketing is one of those terms that gets thrown around a lot but means different things to different people. For a founder trying to grow on a tight budget, it is about getting the most out of every rupee or dollar spent on paid channels. For a seasoned marketer, it is the discipline of tying every campaign directly to a measurable business outcome. This guide answers the questions that come up most often on Google and in real conversations between founders, growth teams, and performance marketers.

What is performance marketing?

Performance marketing is a form of paid advertising where you only pay when a specific action happens, like a click, lead, sale, or app install. The key difference from general digital marketing is accountability. In brand or content marketing, you might spend money hoping it builds awareness over time. In performance marketing, every pound or rupee is tied to a measurable outcome. If it performs, you pay. If it does not, you do not. That direct link between spend and result is what defines it.

What channels fall under performance marketing?

Most paid digital channels sit under the performance marketing umbrella. The most commonly used ones are:

• Paid search (Google Ads, Bing Ads): Bidding on keywords so your ad appears when someone searches for what you sell. You pay per click.

• Paid social (Meta, LinkedIn, TikTok, Pinterest): Running ads on social platforms targeted by demographics, interests, or behaviour. Charged per click, impression, or action.

• Affiliate marketing: Partnering with publishers, bloggers, or influencers who promote your product and earn a commission on each sale or lead they drive.

• Programmatic display: Automated buying of ad placements across websites and apps, usually sold per thousand impressions (CPM) or per click.

• Shopping ads (Google Shopping, Meta Advantage+): Product-specific ads that show images, prices, and reviews directly in search or feed results.

Is performance marketing only suitable for ecommerce, or does it work for B2B and services too?

It works across industries, but the metrics and tactics look different. Ecommerce brands tend to optimise around ROAS and cost per purchase. B2B companies focus on cost per lead, lead quality, and pipeline contribution. Service businesses track bookings, calls, and form fills. The principle is the same, pay for a measurable action, but what counts as a conversion and how you value it changes depending on what you sell.

What is ROAS and what counts as a good number?

ROAS stands for Return on Ad Spend. It is calculated by dividing the revenue attributed to your ads by what you spent on those ads. If you spent 10,000 rupees and generated 40,000 rupees in revenue, your ROAS is 4x.

What counts as good depends entirely on your margins. A business with 70% gross margins can survive on a 2x ROAS. A business with 20% margins might need a 6x or 7x ROAS just to break even. Never benchmark your ROAS target against an industry average without first knowing your own unit economics.

What is CAC and how do I calculate it properly?

CAC stands for Customer Acquisition Cost. At its simplest, it is your total marketing and sales spend divided by the number of new customers you acquired in the same period. Where most businesses get this wrong is in what they include in the numerator. A narrow CAC only counts media spend. A true CAC includes agency fees, tools, creative production costs, and the time cost of your internal team. The narrow version looks better but gives you a misleading picture of what growth actually costs.

How is LTV different from ROAS and which one should I actually be optimising for?

ROAS measures how much immediate revenue a campaign generated relative to what you spent. LTV, or Lifetime Value, measures the total revenue a customer is expected to generate over their entire relationship with your business, not just from the first purchase. For businesses with repeat purchases, subscriptions, or upsell paths, optimising only for ROAS can lead you to cut campaigns that are actually acquiring great long-term customers. If your LTV is three to five times higher than the first purchase value, ROAS will consistently undervalue your marketing.

Why does my ROAS look amazing in the ad platform but the numbers do not add up in my accounts?

This is one of the most common performance marketing frustrations, and the reason is attribution overlap. Meta, Google, and other platforms all want to take credit for every sale. When a customer sees a Meta ad on Monday, clicks a Google Search ad on Wednesday, and buys on Friday, both platforms will often report that conversion as their own. Your platform-reported ROAS is almost certainly inflated. The actual picture only becomes clear when you use independent attribution software or compare platform-reported conversions against actual orders in your CRM or Shopify backend.

What is marketing attribution and what are the different attribution models and which one should I be using?

Attribution is the process of figuring out which marketing touchpoints actually influenced a customer to buy. The main models are:

• Last-click: Gives 100% credit to the final touchpoint before conversion. Simple but almost always misleading for multi-touch journeys.

• First-click: Gives 100% credit to the first touchpoint. Useful for understanding which channels initiate awareness but ignores everything that closed the sale.

• Linear: Splits credit equally across all touchpoints. More fair but treats a brand awareness impression the same as a bottom-of-funnel search click.

• Time decay: Gives more credit to touchpoints closer to the conversion. Often a reasonable default for shorter purchase cycles.

• Data-driven: Uses machine learning to assign credit based on actual patterns in your conversion data. Requires significant data volume to be reliable but is the most accurate when it works.

When is it the right time to scale up a campaign, and when should I pull back?

Scale when a campaign has exited the learning phase, is hitting your target CPA or ROAS consistently over at least two to three weeks, and has headroom to reach more of your target audience without significantly increasing CPMs. Pull back when costs are rising without a corresponding improvement in conversion rate, when the audience is becoming fatigued (signalled by declining click-through rates and increasing frequency), or when your CAC is creeping above what your LTV can justify. Scaling too fast before a campaign has stabilised is one of the most common reasons performance falls off after a budget increase.

What percentage of my marketing budget should go to performance vs. brand marketing?

The Binet and Field framework, which is widely referenced in marketing research, suggests roughly a 60/40 split in favour of brand building for most businesses seeking long-term sustainable growth, though this shifts toward more performance spend for businesses in rapid acquisition phases. In practice, many growth-stage companies run much heavier on performance because it is easier to measure and justify to leadership. The risk is a gradual erosion of brand equity that makes performance costs rise over time as your ads have to work harder to convert an audience that does not know who you are.

Why do my campaigns stop performing after a few weeks even when I have not changed anything?

This is audience fatigue, sometimes called creative fatigue or ad fatigue. When the same people see the same creative repeatedly, engagement drops, click-through rates fall, and your platform starts serving your ads to lower-quality inventory to maintain delivery. The fix is a consistent creative refresh cycle. Most performance marketers aim to introduce new creative every two to four weeks for high-spend campaigns. Watching your frequency metric (the average number of times each person has seen your ad) is a good early warning signal. When frequency creeps above three to four on Meta, creative fatigue is likely already setting in.

How important is creative in performance marketing, and how much should I be investing in it?

Creative has become arguably the single most important variable in paid social performance. In a world where targeting options are converging (because of privacy changes limiting audience data) and algorithm optimisation is commoditised, the quality of your ad creative is what separates campaigns that scale from those that plateau. The brands winning on Meta and TikTok in 2025 are typically testing more creative variations, faster, and letting the algorithm find the winners rather than betting everything on one polished execution.

Does landing page quality actually affect paid ad performance?

Directly and significantly. Google's Quality Score for paid search ads takes landing page experience into account and uses it to determine both your ad rank and the CPC you actually pay.

Beyond that, a high-converting landing page means every click is worth more, which allows you to bid more aggressively and still hit your CPA target. A landing page that converts at 2% versus one that converts at 4% effectively doubles your cost per acquisition on the same ad spend. Landing page optimisation is often the highest-leverage thing a performance marketing team can work on.

Should I be using broad match keywords or exact match on Google Search campaigns?

The right answer has shifted significantly with AI-powered bidding. In the early days of Google Ads, exact match gave you control and broad match wasted budget on irrelevant traffic. Today, with Smart Bidding and data-driven optimisation, broad match can perform extremely well because Google's model has much better signals for predicting which searches will actually convert. The practical advice is to use broad match on campaigns with strong conversion data, Smart Bidding strategies like Target CPA or Target ROAS, and robust negative keyword lists to filter out obvious irrelevant queries. Exact match is still valuable for protecting your brand terms and high-intent commercial queries.

When does it make sense to run LinkedIn ads, and are the high CPCs worth it?

LinkedIn CPCs are genuinely high, often 10x what you would pay on Meta. But for B2B companies targeting specific job titles, company sizes, or industries, the targeting precision can justify the cost if your product has a high enough contract value. A software company selling a 50,000 rupee per month SaaS contract can afford a 3,000 rupee CPL in a way that a 1,000 rupee per month tool cannot. LinkedIn ads tend to work best for generating qualified leads and building awareness among decision-makers, not for bottom-of-funnel direct response. Use them for content promotion, demo requests, and webinar registrations rather than expecting cheap direct conversions.

How much should I be relying on automated bidding versus manual bidding?

For most advertisers in 2025, automated Smart Bidding strategies outperform manual bidding when they have sufficient conversion data to learn from. Target CPA and Target ROAS are the most commonly used and they work well when you have at least 30 to 50 conversions per month per campaign. Below that volume, the algorithm does not have enough signal and manual or enhanced CPC bidding often performs better. The mistake most beginners make is switching to automated bidding too early, before the campaign has enough data, and then concluding that it does not work.

What role is AI actually playing in performance marketing right now, and what is just hype?

The parts that are genuinely working and delivering measurable results include automated bidding (Smart Bidding on Google, Advantage+ on Meta), AI-driven audience expansion, responsive ad formats that automatically combine your creative assets to find winning combinations, and predictive analytics for budget forecasting. The parts that are more hype than substance include AI-generated ad copy that sounds identical to every other brand using the same tool, and fully hands-off automated campaigns that claim to need zero human input. The marketers getting the best results from AI are treating it as a tool that executes faster and at greater scale, not as a replacement for strategy and creative thinking.

What are the most common performance marketing mistakes that founders make in the early stages?

The ones that come up most repeatedly are:

• Spreading budget too thin: Running five channels with small budgets on each means none of them has enough data to optimise properly. Start with one or two and do them well.

• Optimising for the wrong metric: Chasing a low CPL or high ROAS without checking whether those leads or customers are actually valuable to the business long-term.

• Not tracking properly before spending: Setting up attribution, conversion tracking, and a baseline before launching campaigns saves enormous amounts of money and confusion later.

• Scaling too fast: Doubling a budget before a campaign has stabilised almost always hurts performance. Give campaigns time to exit the learning phase first.

• Ignoring creative: Spending all the time on targeting and bidding strategy while running mediocre creative is the most common reason campaigns plateau.

• Not building for retention: Performance marketing brings people in the door but if the product, onboarding, or customer experience does not retain them, the unit economics will never make sense.

Final checklist before launching any performance campaign

Final checklist before launching any performance campaign

Conversion tracking is set up and verified in your ad platform

You have a clear CPA or ROAS target based on your actual unit economics

Your landing page has been tested on mobile and loads in under 3 seconds

You have at least 3 to 5 creative variants ready to test from day one

You know which attribution model you are using and have set up a source of truth outside the platforms

You have a weekly review cadence planned so you can catch problems early

You have defined what success looks like at 30, 60, and 90 days

Final Thoughts

Performance marketing rewards clarity more than almost any other discipline. The clearest picture of your unit economics, the clearest attribution setup, and the clearest connection between your ad spend and your business outcomes, these are what separate the campaigns that scale sustainably from the ones that look impressive for a quarter and then fall apart.

The questions in this guide come up constantly in real conversations between founders trying to grow and marketers trying to explain what they are doing and why. If you have got clear answers to most of them, you are in a genuinely strong position. If several of them exposed gaps, those are worth addressing before adding more budget.

Better data, tighter creative, and honest measurement will take you further than any single campaign tactic.
