Pay per click in digital marketing: what actually works
Pay per click in digital marketing explained: auctions, Quality Score, Google vs Meta vs LinkedIn, INR budgets, ROAS, and PPC vs SEO from a team that runs both.
Most people meet pay per click in digital marketing the same way: they boost a post, spend a few thousand rupees, get nothing back, and decide paid ads are a scam. The ads were not the problem. The setup was. Pay per click is one of the few channels where you can be losing money on Monday and profitable by Friday, but only if you understand what you are buying when you buy a click.
This guide walks through how pay per click in digital marketing actually works, from the auction that decides who shows up, to Quality Score, to picking between Google, Meta and LinkedIn, to budgets in rupees, to measuring whether any of it is paying off. We run paid and organic in-house at Zarle, so the numbers and mistakes here come from accounts we have managed, not from a slide deck.
One honest framing before we start. Paid ads rent attention. The day you stop paying, the traffic stops. That is the opposite of SEO, where the asset keeps working after you stop spending. Neither is better. They do different jobs, and the smart move is usually to run both.
What pay per click really means
Pay per click is an advertising model where you only pay when someone clicks your ad. Not when it shows. Not when someone scrolls past. Only on the click. You set a maximum you are willing to pay, the platform runs an auction, and if you win, your ad appears.
That sounds simple, and the billing is. The part that decides whether you win or lose money is everything that happens before the click and after it.
The auction, in plain terms
Every time someone searches on Google or opens Instagram, an auction fires in milliseconds. Advertisers who want that audience are entered automatically. The platform does not just hand the top spot to whoever bids most. It ranks ads using Ad Rank, which is roughly your bid multiplied by how relevant and useful your ad is.
This is the part beginners miss. A competitor bidding 200 rupees with a sloppy ad can lose to you bidding 120 rupees with a tight, relevant ad. Google rewards relevance because a useless ad at the top makes people stop trusting the results. So the auction is not "who has the deepest pockets." It is "who has the best combination of bid and quality."
There is a happy consequence here. You usually pay less than your maximum bid. A simplified version of Google's formula is: the actual cost per click equals the Ad Rank of the advertiser just below you, divided by your own Quality Score, plus one paisa. Translation: the better your quality, the cheaper your clicks get. Quality is a discount.
Quality Score and why it controls your costs
Quality Score is Google's 1 to 10 rating of how relevant and useful your ad and its landing page are for a given keyword. It is built from three things:
- Expected click-through rate, or how likely people are to click your ad
- Ad relevance, or how closely your ad copy matches what the person searched
- Landing page experience, or whether the page is fast, relevant and actually helps
A high Quality Score means cheaper clicks and better positions. A low one means you pay a premium to show up at all, or you do not show at all. We have taken accounts where the same keyword cost a client 90 rupees a click and got it down to 40 by rewriting the ad, splitting the keyword into a tighter ad group, and fixing a slow landing page. Same keyword. Less than half the cost. Nothing changed except relevance.
If you remember one thing about pay per click in digital marketing, make it this: you are not just bidding money, you are bidding relevance, and relevance is the cheaper currency.
The main platforms and what each is good for
People say "PPC" and mean Google, but pay per click runs across several platforms, each with a different strength. Picking wrong is the most expensive mistake before you have even written an ad.
Google Ads catches demand. Someone typing "root canal in Noida" or "CAT prep course online" is already looking. You are not convincing them they have a need, you are competing to be the answer. High intent, higher cost per click.
Meta, which is Facebook and Instagram, creates demand. Nobody opens Instagram to buy a fitness app, but a good reel and a sharp offer can make them want one. Lower cost per click, lower intent, brilliant for visual products and retargeting.
LinkedIn targets people by job. If you sell to HR heads or hospital procurement managers, you can put your ad in front of exactly that title. Expensive per click, but the targeting is unmatched for B2B.
Here is roughly how the three compare for an Indian advertiser in 2026.
| Factor | Google Ads | Meta (FB/Instagram) | |
|---|---|---|---|
| Typical CPC (India) | Rs 10 to 120, more for legal/finance/SaaS | Rs 5 to 40 | Rs 150 to 650, median around Rs 320 |
| Intent level | High, people are searching | Low to medium, scrolling | Medium, role-based |
| Best for | Capturing existing demand | Creating demand, retargeting | B2B by job title and company |
| Typical lead cost (CPL) | Varies by vertical | Rs 150 to 400 | Rs 850 to 2,500 |
| Sensible monthly test budget | Rs 20,000+ | Rs 15,000 to 30,000 | Rs 1,00,000+ |
For most B2B clients we land on a mix: the bulk of budget on Google to catch buying-intent searches, a slice on LinkedIn for role targeting, and a small amount on Meta for retargeting people who already visited. For an ecommerce or consumer app, that flips, and Meta usually leads.
How a campaign is actually structured
A messy account is the single biggest reason pay per click in digital marketing quietly drains money. Structure is not bureaucracy, it is the thing that lets you spend on what works and cut what does not.
The hierarchy on Google looks like this:
Account
Your billing and overall settings live here. One business, one account.
Campaign
This is where you set budget, location, and the broad goal. One campaign per clear objective. A dental clinic might run one campaign for "general dentistry Noida" and a separate one for "dental implants," because implants are worth far more per patient and deserve their own budget.
Ad group
Inside a campaign, each ad group holds a tight cluster of closely related keywords and the ads written for them. The rule that saves money: one theme per ad group. "Teeth whitening" keywords and "root canal" keywords should never share an ad group, because no single ad can be relevant to both, and irrelevant ads tank your Quality Score.
Keywords and match types
Keywords are the searches you want to show for. Match types control how loosely Google interprets them. Broad match reaches the most people and wastes the most money if left unwatched. Phrase and exact match are tighter. New accounts should lean tight, then widen once they know what converts.
Negative keywords, the underrated lever
Negative keywords tell Google what searches to ignore. If you sell premium courses, you add "free" as a negative so you stop paying for clicks from people who will never buy. We routinely cut 15 to 30 percent of wasted spend in the first month just by building a proper negative keyword list from the search terms report. It is the least glamorous task in PPC and one of the most profitable.
Budgets and bidding in the Indian context
The most common question we get is "how much should I spend." The honest answer is that the platform needs enough data to learn before it can optimise, and starving it guarantees failure.
A few realistic floors for India:
- Google Ads: budget for at least Rs 20,000 a month to gather meaningful data in a competitive niche. In cheap niches you can learn for less.
- Meta lead generation: Rs 15,000 to 30,000 a month as a testing budget before you judge results.
- LinkedIn: the technical floor is about Rs 800 a day per campaign, but you really want Rs 4,000 to 8,000 a day per campaign to generate enough data to optimise.
On bidding, start manual or with a clear target while volume is low, then move to automated strategies like target CPA or target ROAS once the account has 30 or more conversions to learn from. Handing automation to an account with five conversions a month is like asking someone to predict your habits from a single visit. There is nothing to learn from.
Set a daily budget you can sustain for at least 60 days. The accounts that fail are usually the ones that spend hard for two weeks, panic, and switch everything off right before the data becomes useful.
Measuring success: ROAS, CPL and the metric that actually matters
Clicks feel good. They are also the easiest number to fool yourself with. The metrics that decide whether pay per click in digital marketing is working sit further down the funnel.
For ecommerce, the headline number is ROAS, return on ad spend. If you spend Rs 1,00,000 and the campaign drives Rs 4,00,000 in revenue, your ROAS is 4. Whether that is good depends entirely on your margins. A 4x ROAS on a product with 20 percent margin is losing money. The same 4x on a 60 percent margin product is excellent.
For lead generation, ROAS is the wrong lens. You measure cost per lead, then push past it to cost per qualified lead, and finally cost per customer. A Rs 200 lead sounds great until you learn that only one in fifty closes, which makes each customer cost Rs 10,000. A Rs 600 lead that closes one in five costs Rs 3,000 per customer. The expensive lead is the cheap customer. This is the single most common attribution mistake we fix.
Track the full chain: impression, click, lead, qualified lead, sale. Wherever the drop-off is worst is where your money is leaking, and it is rarely where people expect.
PPC vs SEO: when to use which
This gets framed as a fight. It is not. They solve different timing problems.
| PPC | SEO | |
|---|---|---|
| Speed | Traffic the same day you switch it on | Months before meaningful traffic |
| Cost behaviour | Stops the moment you stop paying | Keeps working after you stop spending |
| Best for | Launches, validating demand, fast revenue | Long-term, compounding, cheaper traffic over time |
| Control | Precise control over who sees what, when | Less control, you earn rankings over time |
| Risk | Spend wrong and the money is gone | Slow to start, but durable |
A simple way to choose: if you need revenue in the next 30 to 90 days, start with pay per click. A product launch, a seasonal push, a new clinic that needs patients now, those are PPC situations. If you have six to twelve months of runway and want traffic that gets cheaper over time, invest in SEO.
The real answer for most businesses is both, run together. Paid search tells you within days which keywords and messages actually convert. You then feed those winners into your SEO and content plan instead of guessing for six months. The channels are a feedback loop, not a budget cage match. We wrote a fuller breakdown of the organic side in our guide to SEO in digital marketing if you want to go deeper there.
A real example: edtech lead generation
When we worked with Optima Learning, an AI-driven CAT prep platform, the pressure was lead generation. They needed students enrolling, not just traffic.
The mistake we see edtech brands make is dumping the whole budget into broad Meta campaigns because clicks are cheap. Cheap clicks from people who will never enrol are not cheap, they are just wasteful at a low unit price. We ran high-intent search on Google for terms like "CAT online coaching" alongside an SEO-ready CMS, so the same audience was being captured in both paid and organic. Paid told us in weeks which course angles converted. That insight shaped the content that brought in organic traffic within weeks of launch and kept generating leads after the paid spend was dialled back. Founder Ashwin Chauhan described the result as a build "optimised for conversions," which is the only thing a lead-gen campaign is supposed to deliver.
The lesson generalises beyond edtech. The same logic runs a healthcare lead-gen account: high-intent search captures people actively looking for a treatment, retargeting catches the ones who hesitated, and organic content lowers the blended cost over time.
Money-wasting mistakes to avoid
These are the leaks we find most often when we audit an account.
- Sending clicks to a slow or generic landing page. This wrecks your Quality Score, raises your cost per click, and loses the visitor. Match the page to the ad.
- No negative keywords. You pay for irrelevant searches every single day until someone builds the list.
- One giant ad group with everything in it. No ad can be relevant to fifty unrelated keywords, so relevance and Quality Score collapse.
- Optimising for the wrong action. Counting form fills while ignoring whether those leads ever become customers.
- Switching campaigns off too early. The algorithm needs roughly 30 conversions and several weeks to learn. Two weeks tells you nothing.
- Treating PPC and SEO as either-or. A modest budget split intelligently beats going all-in on one channel almost every time.

Frequently asked questions
What is pay per click in digital marketing?
Pay per click in digital marketing is an advertising model where you pay only when someone clicks your ad, rather than for each time it is shown. You bid for placement in an auction on platforms like Google or Meta, and you control budget, targeting and messaging precisely.
How much does PPC cost in India?
It depends entirely on the platform and your niche. Google Ads clicks commonly run Rs 10 to 120, higher for legal, finance and SaaS. Meta clicks are far cheaper at Rs 5 to 40. LinkedIn sits highest, around Rs 150 to 650 per click. Plan a sustainable monthly budget rather than a one-time burst.
Is PPC better than SEO?
Neither is better, they solve different problems. PPC gives you traffic immediately but stops when you stop paying. SEO takes months but keeps working afterwards and gets cheaper over time. Most businesses get the best result running both, using paid data to guide organic content.
What is a good ROAS?
There is no universal number because it depends on your profit margin. A 4x return on ad spend can be a loss on a thin-margin product and a strong win on a high-margin one. For lead generation, measure cost per qualified customer instead of ROAS.
What is Quality Score and why does it matter?
Quality Score is Google's rating of how relevant your ad and landing page are to a search. A high score lowers your cost per click and improves your ad position. It is built from expected click-through rate, ad relevance and landing page experience. Better relevance literally makes your clicks cheaper.
How long before PPC shows results?
You can see clicks and leads the same day a campaign goes live, but reliable data takes a few weeks. Give a new campaign at least 30 conversions and 60 days before judging it or handing it to automated bidding.
Can I run PPC myself or should I hire an agency?
You can run basic campaigns yourself, and for a small local business that is often fine. The money usually justifies help once spend grows, because the savings from proper structure, negative keywords and Quality Score work tend to exceed the management cost.
