How to choose the right lead generation agency in South Delhi
Picking the wrong agency can drain your budget, slow down growth, and leave your sales team frustrated. Here’s how to make the right call.

Check their industry experience and track record
Before saying yes, look at the work they have actually done. A solid agency should have results in your industry and clear proof of performance. Ask for case studies, testimonials, and real examples of campaigns they have executed for businesses similar to yours.
Also check third party reviews and recognition. If they already work with SaaS, e-commerce, real estate, or professional services brands in South Delhi, they will understand your buyers and what kind of outreach works best.
Understand how they qualify leads
High lead volume means nothing if most leads are unfit. The right agency will qualify leads using your ideal customer profile instead of sending random contacts. Ask them:
- How do you define a qualified lead for my business
- How do you score leads
- How do you check if leads match my ICP
- How do you filter out low intent prospects
An agency that takes time to understand your sales process will send leads your team actually wants to follow up with.
Review their technology stack and integration ability
Modern lead generation runs on tools. Check what they use for automation, CRM, verification, analytics, and email outreach. Most importantly, confirm whether their systems integrate smoothly with yours. You do not want data getting stuck in tools or manual work slowing down your sales cycle.
Look for transparency in reporting and communication
Great agencies like ZeroAdo act like partners. They should give you clear weekly or monthly reports showing metrics like cost per lead, conversion rates, opportunities created, and ROI. Ask:
- What dashboards will I get
- How often will you share updates
- Who will be my primary contact
- How frequently will we review performance together
Remember: Consistency in communication builds trust and keeps campaigns on track.
Understand their targeting and outreach strategy
Before signing, you should know exactly who they are reaching out to on your behalf and how. Ask for clarity on:
- Which businesses and decision makers they will target
- What messaging and content they will use
- How many prospects they will reach each month
- Which channels they will use such as email, LinkedIn, or phone
This ensures you are not paying for irrelevant outreach that brings unfit leads.
Evaluate cost and expected ROI
Agencies have different pricing models. Some charge per lead, some on retainer, and some on performance. Understand how their pricing works and ask:
- What is the cost per lead
- How many leads can I expect monthly
- What is your average conversion rate
- When can I expect to see results
Tip: Choose an agency that talks about revenue and ROI, not just lead numbers.

FAQs about best lead generation agency in South Delhi
Most businesses start seeing early traction in around 30 to 45 days. Full, consistent results usually show up in 60 to 90 days once campaigns, targeting, and automation settle in. Lead generation is a system, not a switch, so the results grow stronger over time.
It depends on your industry. For most B2B companies in South Delhi, the CPL usually falls between INR 300 and INR 1500. High ticket niches like SaaS, real estate, and consulting can go higher. The focus should be on qualified leads, not the cheapest leads.
If you want speed, expertise, and lower cost, hiring an agency is usually the better choice. Because building an in house team takes hiring, training, tools, and months of trial and error. Agencies already have the systems and experience to start delivering results faster.
Simple. You should see improvements in your pipeline. Look at metrics like qualified leads, meeting booking rate, conversion rate, and revenue generated. If you only get reports with impressions and clicks, they are not delivering real value.
Ask things like who will manage your account, how they qualify leads, what tools and automation they use, how they report performance, and what results they have delivered for businesses similar to yours. Their answers will immediately tell you how serious, experienced, and reliable they really are.
Yes, most good agencies can. What matters is their understanding of your ICP, your buyer journey, and your sales process. If they ask the right questions and show experience in B2B, they can adapt quickly to almost any industry.
