What is a lead? 3 levels of leads in marketing and how to convert customers.

The term “lead” is certainly familiar to marketers, yet not everyone fully grasps its nuances. Today, OMI shares everything you need to know: What exactly is a lead? Why are leads crucial for businesses? How can you convert leads into customers to boost revenue? Find all the answers in the article below. Let’s dive in!

What is a lead?

In marketing, a lead is a potential customer who has shown interest in the products or services you offer. These are individuals who voluntarily provide their information to you.

Examples include: filling out a registration form, signing up for a trial, or requesting a consultation.

Clearly, leads have become a key metric that businesses prioritize studying and tracking regularly. The more high-quality leads a business generates, the greater its sales opportunities—ultimately driving higher revenue.

3 main types of leads in marketing

In addition to understanding what a lead is, you also need to be familiar with the three main types of leads in marketing:

Information Qualified Lead (IQL)

Information Qualified Leads (IQLs) are prospects captured during the Awareness stage of the marketing funnel.

At this stage, target customers recognize the problems they need to solve but are still struggling to find a solution.

Consequently, businesses need to provide useful information addressing the issues related to their products or services that the customer is curious about. By doing so, it becomes easier to collect personal details such as name, email, address, occupation, etc.

Marketing Qualified Lead (MQL)

Marketing Qualified Leads (MQLs) are potential customers who have provided basic contact information—such as an email address or phone number—as a result of the marketing team’s efforts.

To generate MQLs, businesses launch marketing campaigns that leverage customer insights, encouraging prospects to show interest in a product or service by submitting their information.

Potential customers classified as MQLs might take actions such as:

Downloading eBooks, documents, or reports;

Attending a seminar or webinar;

Signing up for detailed product information;

Registering for a product trial;

Requesting a consultation;

…

Sales Qualified Lead (SQL)

In marketing, Sales Qualified Leads (SQLs) can be simply defined as prospects who have been vetted by the marketing team (as MQLs) and are deemed ready to purchase the product. At this stage, businesses need to adopt a persuasive approach and offer trial experiences to encourage prospects to make a quick purchasing decision.

If your marketing campaign yields positive results, the conversion rate from MQLs to SQLs will be high. Conversely, if this rate is low, the marketing and sales teams should meet to refine the criteria used to evaluate target customers more accurately.

3 Main Types of Marketing Leads

Converting Leads into Customers

Leveraging Behavioral Data

A crucial initial step in successful conversion is creating distinct buyer personas based on your target audience’s behavior. These insights provide details on how to guide specific lead segments from the top of the sales funnel to the bottom.

Lead Nurturing

Lead nurturing is the process of building relationships with potential customers and fostering those connections throughout the entire sales cycle.

To effectively nurture leads, businesses need the right tools. OMICall is an optimal choice, offering multi-channel customer care solutions—such as Facebook Fanpage, Email, Hotline, and Zalo OA—to help businesses boost customer interaction and improve conversion rates across various channels.

Seamlessly Converting Leads into Customers

Offer customers a compelling deal. Be sure to seize every opportunity to close the sale.

For example: During holidays, people tend to spend more than usual. This is the perfect time to present a special offer that encourages them to complete their purchasing journey.

Leveraging Reviews and Referrals

A common mistake in sales is failing to capitalize on free promotion. If customers post glowing reviews on social media or review sites, gather them. Nothing is more persuasive to new prospects than positive feedback from existing customers.
