How to Choose a Lead Generation Agency in Delhi (Checklist)
If you're vetting lead generation agencies in Delhi, the short answer is this: look for proof of past results in your industry, clarity on how leads are sourced and qualified, transparent reporting, and a contract that doesn't lock you into vague deliverables. Everything else — pricing, tools, team size — matters less than whether the agency can show you real numbers from real campaigns and explain their process without hiding behind jargon.
Delhi and the wider market has no shortage of agencies claiming to deliver "guaranteed leads" or "1000+ qualified leads a month." Most of that is marketing noise. The businesses that get burned usually skipped the same handful of checks before signing. This checklist walks through exactly what to verify, what questions to ask, and which red flags mean you should walk away.
Start With What "Lead Generation" Actually Means for Your Business
Before evaluating any agency, get clear on what a qualified lead looks like for you. A B2B SaaS company and a real estate builder in Gurgaon have completely different definitions of a "good lead" — one might mean a decision-maker who booked a demo call, the other might mean a site-visit request from someone with actual budget.
Agencies that skip this conversation and jump straight to pricing or platform pitches (Google Ads, Meta Ads, LinkedIn outreach) are optimizing for lead volume, not lead quality. A capable agency will ask about your sales cycle, average deal size, and past conversion rates before proposing a strategy — the same way Buzzspire Media's team of digital marketing experts approaches every new client onboarding.
The Checklist: What to Verify Before Signing
1. Ask for case studies from your actual industry, not generic ones
Every agency will show you a results deck. The question is whether those results are relevant. A checklist that worked for a D2C skincare brand tells you little about lead generation for a B2B manufacturing company. Ask specifically: "Do you have a client in my industry or a similar sales cycle, and can I see the numbers?" If they can't produce this, or only offer testimonials with no data attached, treat that as incomplete evidence rather than proof.
2. Understand their lead sourcing and qualification process
This is where most vetting conversations fall short. Ask the agency to walk you through, step by step, how a lead moves from ad click (or outreach) to something your sales team can actually work with. Specifically:
What platforms or channels will they use, and why those over others for your industry? A strong PPC / paid ads strategy matters here more than most businesses realize.
Do they run any qualification layer — a form with screening questions, a call verification step, an MQL/SQL scoring system — or do they hand you raw form-fills?
How do they define "qualified" for your account specifically?
An agency that can't answer this clearly, or gives a vague "we use AI-powered targeting" answer without explaining the actual mechanics, likely doesn't have a real process — they're running ads and forwarding whatever comes in.
3. Ask about reporting frequency and what metrics they actually track
Reporting should go beyond impressions, clicks, and cost-per-lead. Ask what a typical weekly or monthly report looks like, and request a sample. You want visibility into:
Cost per qualified lead (not just cost per lead)
Lead-to-opportunity or lead-to-sale conversion rate, if they track it
Which channels or campaigns are underperforming and what they're doing about it
If an agency's idea of reporting is a screenshot of ad spend and a lead count, you'll have no way to judge whether the campaign is actually working for your business, only whether it's generating activity.
4. Check how leads are delivered and how fast
A lead sitting unattended for six hours has a dramatically lower chance of converting than one you call within five minutes. Ask how leads reach you — real-time CRM push, instant email/WhatsApp notification, or a batch export at the end of the day. Agencies that only deliver leads in a weekly spreadsheet are optimizing for their own reporting convenience, not your sales team's ability to follow up fast.
5. Look beyond paid ads — check their organic and local presence capabilities
Paid leads dry up the moment you stop spending. A well-rounded agency pairs paid campaigns with SEO for long-term organic traffic and an optimized Google Business Profile for local search visibility — both of which keep generating leads even during months you scale ad spend down.
6. Clarify pricing structure and what's actually included
Delhi agencies typically price lead generation work in one of three ways: a flat monthly retainer, a percentage of ad spend, or a cost-per-lead model. Each has trade-offs — a cost-per-lead model can incentivize volume over quality if there's no qualification standard attached, while a retainer needs clear deliverables so you're not paying for vague "strategy and optimization" work. Get the pricing model in writing along with exactly what's included: ad spend management, creative production, landing page building, CRM setup, and reporting should each be spelled out rather than bundled into an ambiguous "full-service" line item.
7. Ask what happens if results don't materialize
No legitimate agency can guarantee a fixed number of leads — too much depends on your industry, offer, budget, and market conditions. What you can ask for is their process when a campaign underperforms: do they run a diagnostic review after a set period (commonly 30 or 60 days), adjust targeting and creative, and communicate proactively, or do you find out only when you ask why lead flow dropped?
8. Talk to an existing or past client if possible
If the agency is confident in their work, they should be able to connect you with a current client for a short reference call, or at least share a case study with contact-verifiable results. Hesitation here is worth noting — it doesn't automatically mean something's wrong, but it removes one of the more reliable ways to verify claims made in a sales pitch.
Red Flags to Watch For
Certain patterns show up repeatedly among agencies in Delhi that overpromise and underdeliver:
"Guaranteed leads" language with no qualification criteria attached. Guaranteeing lead volume without defining lead quality is a way to hit a number on paper while sending you unusable contacts.
No willingness to share a sample report or dashboard before you sign. If they can't show you what reporting looks like during the sales process, don't assume it'll improve after the contract is signed.
Long lock-in periods with no early exit or performance review clause. A 12-month contract with no 60- or 90-day checkpoint gives the agency little incentive to course-correct early.
Vague answers about which channels they'll use. "We'll figure out what works" during the pitch stage usually means there's no account-specific strategy, just a default playbook applied to every client.
Pricing that seems significantly below market rate. Unusually cheap packages often mean under-resourced account management, low-quality traffic sources, or bought/scraped contact lists rather than genuinely generated leads.
No clarity on who owns the data and creative. Ask upfront whether the leads, ad accounts, and creative assets belong to you or the agency if you end the engagement — this matters more than it seems once you're a year into a relationship.
A Quick Vetting Script You Can Use
When you're on a call with a shortlisted agency, these five questions tend to surface the most useful signal quickly:
"Show me a case study from a client with a similar sales cycle to mine — what were the actual numbers?"
"Walk me through exactly how a lead gets qualified before it reaches my team."
"What does a typical report look like, and can I see a sample?"
"What's your process if lead quality or volume drops in month two?"
"Can I talk to a current client as a reference?"
An agency's willingness to answer these specifically, rather than with general marketing language, tells you more about how they'll actually work with you than any pitch deck will.
