Using Facebook Ads Library to Find Clients for Your Agency

Finding clients for an ads agency is hard when you’re targeting cold businesses.

Most lists are outdated. Most companies aren’t running ads. Most don’t even have budget.

Facebook Ads Library changes this completely.

It lets you find businesses that are already spending money on ads right now.

That means:

• they understand advertising
• they have budget
• they are much easier to convert

If you use it правильно, you can build a consistent pipeline of warm leads without guessing.

Why Facebook Ads Library is Perfect for Client Prospecting

This is one of the simplest but most powerful lead generation channels.

1. You’re targeting warm leads

These businesses are already paying for ads.

You’re not convincing them to start. You’re helping them improve.

Big difference.

2. You can see their creatives

You instantly understand:

• how they position offers
• what they promote
• how strong (or weak) their ads are

In many cases, you’ll spot problems in seconds.

3. You can estimate budget indirectly

If a company runs:

• 1–2 ads → testing
• 5–10 ads → consistent spend
• 20+ ads → serious budget

More ads = more opportunity.

Step-by-Step: How to Find Clients Using Facebook Ads Library

This is the exact process agencies use.

Step 1 - Search by niche + location

Use simple, customer-style queries.

Examples:

• “dentist near me”
• “roof repair”
• “personal injury lawyer”
• “kitchen remodeling”

Set location:

• United States (or your target market)

This gives you relevant advertisers instantly.

Step 2 - Identify serious advertisers

Don’t contact everyone.

Look for:

• multiple active ads (5+)
• consistent creatives
• not just one test campaign

These are businesses already investing.

Step 3 - Visit their website or page

Click through and check:

• website quality
• landing page speed
• presence of funnel
• contact options

You’re looking for gaps.

Example:

• slow site
• no clear CTA
• weak offer

That becomes your pitch.

Step 4 - Qualify leads

Before outreach, filter:

Good lead:

• real business
• active ads
• has website
• clear service

Bad lead:

• random pages
• no site
• irrelevant niche

Quality > quantity.

How to Scale This Process

Manual workflow looks like this:

• 2–3 hours → 20–30 leads
• most without emails

It works, but it doesn’t scale.

Scaling with tools (AdsLeadz)

Instead of manual copy-paste, AdsLeadz lines up with what we list on pricing & features:

• Find advertisers in Meta Ads Library (keyword, industry, location—your normal search flow)
• Extract public contacts from advertiser sites: emails, phones, social links
• Qualify by ad spend signal and review results in a table
• Export to CSV for your CRM or outreach tools
• Chrome extension works inside the library; Web adds scale, advanced filters, and REST API access

Filters (Chrome extension + Web; the last three are Web-only):

• Ads count filters — find advertisers that look like real spend, not one-ad tests.
• Running days filters — keep pages that have been running long enough to care about.
• Active status filters — stay on what is actually live in the library.
• Date filters — limit ads to the time window you want.
• Negative keyword filters — remove noisy niches from the results.
• Unique results — dedupe pages so your list stays clean.
• Platform filters — narrow Facebook vs Instagram when that matches your ICP.
• Shopify filters — target or avoid Shopify stores (Web only).
• Vertical exclusion filters — cut e‑commerce, apps, and other verticals you do not want (Web only).
• Contact-type filters — only email or only phones for cleaner outreach lists (Web only).

Typical outcome with a focused search:

• 300–1k leads in minutes instead of hours
• No manual scraping or tab-hopping

It turns Facebook Ads Library prospecting into a repeatable system.

Common Mistakes

1. Targeting everyone

You don’t need all businesses.

Focus on:

• those running multiple ads
• those with clear budget

2. Contacting test advertisers

If they run 1 ad → skip.

They’re not ready yet.

3. Ignoring location

Geo matters.

A “dentist” in the US and in a small market are very different leads.

4. Sending generic messages

Bad:

Hi, we run ads

Good:

Saw you’re running ~10 ads for roofing Your landing page loads in ~4s - we helped reduce this to 2s and increase leads by 28% Want me to show what we’d fix?
