How to Build a Targeted Prospect List in Minutes Using LeadThur's Search Filters

If you've ever spent a Friday afternoon copying business names and email addresses from Google Maps into a spreadsheet, you know the pain. Your fingers cramp. The data is inconsistent. And by Monday, half the numbers you saved are disconnected.

There's a faster way. LeadThur's business search lets you find local and niche businesses by query and location. You type what you're looking for, pick where, and get a list of matching businesses pulled fresh from the web — not from a file prepared months ago.

But here's the thing: a search is only as good as the filters you apply. Run one broad query and you'll get a mess. Run a few targeted ones and you'll have a clean list in under five minutes.

This guide walks you through the exact process — from choosing your queries to refining results to avoiding the mistakes that waste your time.

Why Your Current Approach Is Costing You Deals

Before we get into the how, let's be honest about the problem.

Manual list building is slow. You search Google Maps, visit websites, hunt for contact pages, and copy everything into a spreadsheet. For 100 businesses, that's easily three to four hours of tedious work. And the data quality? Inconsistent. Some listings have emails. Some don't. Some are outdated. Some are outright wrong.

Buying a lead list isn't much better. Those lists are often scraped months ago and sold to dozens of other salespeople. By the time you get them, the emails have bounced, the decision-makers have changed roles, and your reply rate sits somewhere near zero.

As we covered in our comparison of LeadThur vs. manual lead sourcing, the real cost isn't the tool — it's the hours you burn on work that could be automated.

LeadThur solves this by pulling data on demand. When you run a search, you're getting current information, not a stale file. That alone makes a difference in whether your emails land in inboxes or bounce back.

Step 1: Start With a Clear Ideal Customer Profile

You can't build a targeted list if you don't know who you're targeting. Sounds obvious, but most people skip this step.

Before you open LeadThur, write down three things:

• Who they are: What industry? What size? What location?
• What they need: What problem do they have that you solve?
• What signals matter: Are you looking for established companies only? Do you need businesses with websites? Do you want to avoid one-person operations?

For example, if you sell accounting software to small businesses, your ideal customer might be:

• Registered companies in Lagos
• With 5–50 employees
• In retail, hospitality, or professional services
• That already have a web presence

That's a concrete profile. Now you can translate it into search queries.

Step 2: Structure Your Search Queries

This is where most people go wrong. They type one broad query like "businesses in Lagos" and hope for the best. The result? A mix of irrelevant results — small-scale operators, inactive businesses, and companies that have nothing to do with what you sell.

Instead, think in terms of specific niches. LeadThur lets you search for local and niche businesses by query and location. So you can search "logistics companies in Ikeja" or "fintech startups in Nairobi" and get matching businesses.

Here's how to structure your queries:

Use Industry + Location

This is the most basic structure. Instead of "businesses in Accra," try:

• "catering services in Accra"
• "IT consulting firms in Accra"
• "pharmaceutical distributors in Accra"

Each query targets a specific segment. You'll get cleaner results because the search is matching both the industry and the location.

Add Qualifiers

If your ideal customer is a certain size or type, add that to your query:

• "medium-sized manufacturing companies in Nairobi"
• "boutique hotels in Cape Town"
• "corporate law firms in Lagos"

These qualifiers help filter out the small-scale operators and informal businesses that won't buy from you.

Think in Synonyms

Different businesses describe themselves differently. A "logistics company" might call itself a "freight forwarder" or a "haulage service." Run multiple queries with different terms to capture the full market.

For example, if you're targeting real estate agencies in Abuja, try:

• "real estate agencies in Abuja"
• "property management companies in Abuja"
• "real estate developers in Abuja"

Each query takes two to three minutes to run. That's time well spent compared to hours of manual research.

Step 3: Run Your First Search

Let's walk through a real example. Say you're a freelance web designer targeting small businesses in Lagos that need better websites.

Your first query might be: "restaurants in Victoria Island"

Here's what happens:

1. LeadThur pulls a list of restaurants in that area.
2. You see business names, locations, and any contact details available.
3. You scan the results and start eliminating what doesn't fit.

The key is to treat this as a starting point, not the final list. A single broad search returns a mix of irrelevant results. That's normal. The filtering comes next.

Step 4: Filter Like You're Eliminating, Not Just Selecting

Filtering is a process of elimination, not just selection. You're not looking for reasons to keep a prospect. You're looking for reasons to cut them.

Ask yourself these questions as you review results:

• Is this business still active? (Check for recent reviews or website updates.)
• Is it the right size? (A one-person operation probably won't need your enterprise software.)
• Is it in the right location? (If you only serve Lagos, a business in Port Harcourt is a waste of time.)
• Is it the right type? (A fast-food joint isn't the same as a fine-dining restaurant.)

This is where most people make mistakes. They see a list of 200 businesses and think, "Great, I'll contact all of them." That's lazy thinking. A small list of 50 well-qualified prospects often outperforms a list of 1,000 scraped emails — a point echoed in Nimble's practical tips on building prospect lists.

Here's a practical filter workflow:

1. Remove duplicates: The same business might appear under slightly different names. Merge them.
2. Remove inactive businesses: If a business hasn't posted or updated anything in two years, it's probably not a good prospect.
3. Remove mismatches: If a result doesn't match your ideal customer profile, cut it. Don't rationalize keeping it.
4. Prioritize: Rank what's left by fit. The top 20% are your first outreach wave.

This approach saves you from wasting time on prospects that were never going to convert. For more on this, check out our checklist for verifying Nigerian businesses before you pitch them.

Step 5: Run Multiple Targeted Queries

One query won't give you a complete list. The market is too fragmented. That's why you need to run several targeted queries to get cleaner data from the start.

Let's continue with the web designer example. Instead of one query for "restaurants in Victoria Island," you might run:

• "restaurants in Victoria Island"
• "cafes in Victoria Island"
• "bars in Victoria Island"
• "hotels in Victoria Island"

Each query gives you a different segment of the hospitality industry. Combined, they give you a fuller picture of potential clients in that area.

How many queries should you run? It depends on your niche. For a narrow niche like "fintech startups in Nairobi," two or three queries might be enough. For a broader niche like "logistics companies in Lagos," you might need five or six to cover all the sub-segments.

The key is to stop when you're seeing diminishing returns. If your last three queries returned the same businesses you already found, you're done.

Step 6: Avoid These Common Filtering Mistakes

Even with good queries, people make mistakes that ruin their lists. Here are the ones I see most often:

Mistake #1: Ignoring Location Specificity

Nigeria is a big country. "Logistics companies in Lagos" is different from "logistics companies in Ikeja." The more specific your location, the more relevant your results — especially if you're a local business that can't serve clients outside your area.

For Nigerian businesses, think in terms of states, cities, and even neighborhoods. If you're a freelance designer in Lagos, you probably don't want clients in Kano. That's a travel nightmare.

Mistake #2: Not Checking for Active Status

A business that closed six months ago is not a prospect. Neither is one that's been dormant for years. Always check whether a business is still operating before you add it to your list.

Signs of an active business include recent social media posts, a working website, and current Google Maps listings. If you can't verify activity, move on.

Mistake #3: Keeping "Almost" Prospects

You know the type. The business is close to your ideal customer profile, but not quite. They're in the right industry but the wrong size. Or the right location but the wrong specialty.

Cut them. Every "almost" prospect you keep is a distraction from the ones that actually fit. As Apollo's analysis of advanced search filters points out, the right filters help you focus on the leads most likely to convert — not the ones that merely look similar.

Mistake #4: Stopping at the First Page of Results

LeadThur returns a list of matching businesses, but the first page isn't the whole story. Scroll through the results. Look at the full list before you start filtering. You might find gold on page three that you would have missed.

Step 7: What to Do After You Export Your List

You've built your list. Now what?

First, don't contact everyone at once. Start with your top 20 prospects. Personalize your outreach. Reference something specific about their business. Show that you did your homework.

Second, verify your contacts. A list is only as good as its data. Check that emails are valid and phone numbers work. Our guide to building high-quality lead lists for sales teams covers this in more detail.

Third, clean your list regularly. Remove hard bounces immediately. Update role changes quarterly. A list that sits for six months becomes stale — and stale lists produce low reply rates.

Finally, track your results. Which queries produced the best leads? Which filters eliminated the most junk? Over time, you'll learn what works for your specific market and refine your approach.

Why This Beats Buying a Lead List

The difference comes down to freshness and fit.

A purchased lead list is a static file. It was compiled at some point in the past, and it hasn't changed since. Businesses close. People change jobs. Emails go dead. By the time you buy that list, a chunk of it is already useless.

LeadThur pulls data on demand. When you run a search, you're getting current information. That means fewer bounces, more replies, and a better return on your outreach effort.

There's also the question of fit. A purchased list is generic — it's the same list sold to everyone. But when you build your own list with targeted queries, you're creating something specific to your business. You're filtering for the exact type of prospect you want to reach.

That's why a list of 50 well-qualified prospects often outperforms a list of 1,000 scraped emails. Quality beats quantity every time.

Frequently Asked Questions

How do I choose the right search query for my niche?

Start with your ideal customer profile. Write down what your best clients have in common — industry, size, location, and needs. Then translate that into search queries using industry terms and qualifiers. If you sell to restaurants, search "restaurants in [location]." If you sell to tech companies, search "software companies in [location]." Refine as you see what works.

What location filters should I use for Nigerian businesses?

Be as specific as possible. Instead of "Lagos," try "Victoria Island" or "Ikeja." Instead of "Abuja," try "Wuse" or "Garki." The more specific your location, the more relevant your results. This is especially important if you're a local business that can't serve clients outside your area.

How many queries should I run to build a solid list?

It depends on your niche. A narrow niche might need only two or three queries. A broader niche might need five or six. Run queries until you stop finding new businesses. If your last few queries return the same results, you've covered the market.

How do I know if my list is too broad or too narrow?

If you're seeing lots of irrelevant results, your queries are too broad. Add more qualifiers — industry, size, location. If you're getting very few results, your queries are too narrow. Broaden your terms or try synonyms. The sweet spot is a list where most results fit your ideal customer profile.

What should I do after I export the list?

Start with your top 20 prospects. Personalize your outreach. Verify contact details before you send anything. Clean your list regularly — remove hard bounces immediately and update role changes quarterly. Track which queries produced the best leads and refine your approach.

How is this different from buying a lead list?

Purchased lists are static files compiled in the past. They go stale quickly. LeadThur pulls data on demand, so you get current information. You also control the filters, which means your list is tailored to your specific needs — not a generic file sold to hundreds of other salespeople.
