Why AI Lead Generation is Effective?


Digitization has transformed lead generation practices. They’re not limited to traditional ways of hosting events and cold calling anymore. Businesses now use omnichannel outreach via emails, websites, apps, and social media to reach maximum potential customers.

With so many of these communication channels, sales cycles have become longer and more complex. This has made work highly tedious and time-consuming for both marketing and sales teams. They struggle to generate and keep up with a high volume of quality leads.

Lead generation and research alone consume about 21% of a B2B sales rep’s time and at least half the budget of most marketers. And despite best efforts, nearly 79% of leads never convert.

Here are some reasons why AI can help you generate and nurture better leads:

  • An AI-powered tool can analyze a huge volume of data from multiple sources in real-time “without getting tired.”
  • It can easily overcome the information overload that humans often face.
  • AI can find patterns in data. Humans may not have such strong observations and benefit from data-driven insights.
  • Above all, AI can multitask quite efficiently.

What’s more? It can help generate high-quality leads, guide sales reps on prospects that need attention, and recommend how to reach the right leads with the right message at the right time.

Businesses that implement AI see a tremendous return on investment. Research shows enterprises that used AI-enabled lead-generation tools saw a 15% to 20% increase in sales productivity and 20% in order management throughput.

Additionally, about 84% of business executives believe AI can give them an edge over their competitors.

7 Ways to Use AI for Lead Generation

There are multiple strategies on how to use AI for lead generation effectively.  AI technology facilitates the automation of various outreach tasks, allowing teams to engage potential customers more effectively while saving significant time and resources. Below, are 7 ways how to use AI to enhance your lead generation process

1. Lead qualification 

Businesses collect leads in many ways: social media platforms like LinkedIn, websites, apps, email, live events, online content, referrals, and more. A robust AI system can support this extensive process in several ways. Machine learning software can analyze your customer data, observe patterns, create an ideal customer profile (ICP), and find leads that fit your existing target persona.

AI-driven tools scour the web for people and businesses that match your target audience, creating a pre-qualified prospect list for your sales and marketing to use as a starting point. 

2. Campaign optimization

Besides finding leads, AI software can also precisely locate the right target audiences for B2B marketing campaigns and segment them based on their similarities or differences. 

It can quickly identify campaigns that work for a particular target audience across different channels and automatically allocate resources to those performing well. Moreover, it can optimize the ads and campaigns’ content and call-to-actions (CTAs) in real-time and improve the campaign response rate.   

For example, if the algorithm learns ads with "call now" as CTA perform better among prospects than the ones with "book a call," the AI tool automatically changes the ads with better-performing CTA in real-time.   

3. Predictive lead scoring 

Time is money, and you don't want to burn dollars or hours chasing the wrong prospects. Once you have a list of prospects, the AI system can use machine learning techniques such as classification, clustering, and regression to effectively qualify and score your leads, saving you time and energy.

AI models study the actual behavioral patterns of previous leads and the company's conversion history to score and rank prospects. It also predicts the time needed to close deals. 

With a ranked list, the model recommends qualified leads for the sales team to prioritize to get maximum value. The sales reps can look at the prospect rankings and make data-driven decisions than guesswork and intuition to pursue a lead, boosting their win rate. 

4. AI-powered lead engagement

If you don't engage and nurture your leads at the right time, they fall through the cracks. That's bad for business. AI comes to the rescue here too. AI technologies, such as AI SDR tools, enable automated and personalized follow-ups across multiple channels, ensuring leads remain engaged throughout the sales process. These tools help SDRs efficiently manage outreach, ensuring no prospect is overlooked.

AI assistants follow your leads promptly and persistently until it gets a positive response. Given how 80% of leads need an average of five follow-ups after initial contact to close a deal, AI can save time and effort for the sales team and eliminate the human error of forgetfulness. It can act as a radar to track lead engagements across channels and provide lead nurturing opportunities. 

5. Chatbots

Chatbots are one of the most popular AI lead engagement tools. These intelligent bots use conversational AI to engage customers round the clock across multiple channels. A bot not only converses with visitors who reach out via websites or apps, but it also analyzes real-time interactions, assesses their intent, and qualifies and segregates leads from contacts for the sales team. 

While interacting with a prospect or customer, a bot can seamlessly hand them off to the live sales rep. It helps move a lead forward when it identifies a need for human attention or the customer’s need is too complex for the system to understand. 

6. Personalization  

Another aspect of AI-powered engagement is personalizing content for consumers. Based on past browsing and content consumption habits, AI tools can send hyper-personalized content to leads and online visitors, spiking interest in the business and ultimately driving conversions.

7. Predictive recommendations

AI tools can analyze customer sentiments, likes, dislikes, interests, pain points, competitor involvement, and overall prospect engagement during their interactions. They recognize when leads are on track to convert or at risk and offer actionable tips on the best actions to take to accelerate sales. Such predictive recommendations can help the sales team send the right message to the right customer at the right time through the right channel
