ZoomInfo VS Apollo.io: Search Engine

When choosing new sales tools for building prospecting lists, search capabilities and filters are as important as data accuracy and data quality.

Now, let’s compare the search filters in Apollo VS ZoomInfo.

ZoomInfo

ZoomInfo provides an advanced search engine that allows sales reps to filter prospects by multiple criteria to ensure precise targeting.

Users can conduct highly specific searches based on industry, job title, company size, location, revenue, funding type, etc.

ZoomInfo advanced filters include:

• Contact filters
• Company filters
• Locations
• Scoops
• Technologies
• Engagement
• Exclude Exported Contacts

If you want to start your research by typing keywords on the Search Bar, you can type:

• company names
• industries
• contacts

The next search bar you have is only for finding the right filter.

You can also put search queries wherever you see a free text box.

ZoomInfo’s search engine supports Boolean search logic, allowing for complex query construction that further refines results.

In ZoomInfo Sales, 7 filters support Boolean operators and modifiers:

• Job Title
• College/Degree
• Web Reference Keywords
• Company Name
• Company Description Keywords
• Industry keywords
• Scoops Description Keywords

Apollo.io

Apollo.io’s search engine is designed to help SDRs, marketing teams, and all users quickly identify and connect with potential leads.

The interface is user-friendly for navigating the filters. Its advanced search filters, which include industry, company size, and job title, are similar to ZoomInfo’s.

Apollo.io Contact data filters include:

• Lists

• Job Titles
• Company
• Location
• Employees
• Industry & Keywords
• Buying Intent
• Scores
• Sequence

This comprehensive filter list can find anyone in any market strategy case.

On the other hand, company data filters include:

• Lists

• Industry & Keywords
• Buying Intent
• Website Visitors
• Technologies
• Revenue
• Funding
• Job Postings
• Scores

• Stage

Both tools include powerful and advanced search filters that give precise search results.

However, there are filters that you can find only in one sales intelligence platform: either ZoomInfo or Apollo.io.

Different search filters show their position in the market, who they target, and what problems they solve.

ZoomInfo VS Apollo.io: Database And Sources

Now, let’s see where both tools get their data from.

ZoomInfo

ZoomInfo collects B2B sales data from trusted sources using advanced automation and validation to ensure accuracy.

It uses tools like the Neverbounce, Chorus, or FormComplete features to enrich and verify data accuracy across the platform.

Key data collection methods include:

• Web Crawling: They get publicly available data from websites, social media, and news articles.
• Data Partnerships: Trusted partners help to enrich their databases.
• Human Research and Verification: In-house teams continuously improve the database.
• AI and ML: Artificial intelligence and machine learning analyze existing data patterns and improve quality.
• Contribution Networks: Tracks email signatures from users’ inboxes to collect additional data.

ZoomInfo Data is less real-time than Sales Navigator because it has special data enrichment teams that check the accuracy of the data provided by the users.

Apollo.io

There are 4 main ways Apollo collects data:

• Data Contributor Network: 2 million data contributors share information about their business contacts as they use Apollo services, allowing Apollo to perform verification checks against connected inboxes and CRMs.

• Engagement Suite: Apollo’s powerful engagement tools allow it to track email responses and bounces, collecting and verifying valid emails against invalid ones.

• Public Data Crawling: Apollo uses proprietary algorithms that regularly crawl the web at scale, analyzing public-facing websites and building a comprehensive index of people and company data.

• Third-Party Data Providers: Apollo processes over 270 million monthly records from carefully vetted third-party data providers. These partnerships add high-quality, verified data to Apollo’s highly accurate and growing database.

Each tool makes a point about the presence of transparent data collection sources. You can trust the data you get and use it for your outreach campaigns.

ZoomInfo VS Apollo.io: Plans & Pricing

Last but not least, the price plans. Let’s see what they offer financially.

ZoomInfo

ZoomInfo pricing structure is determined by several key factors, including:

• Features and functionality: The depth and breadth of functionality a customer requires.
• Number of licenses: The number of user licenses required.
• Credit usage: The consumption of credits representing professional or company profile exports.

However, their website doesn’t provide any exact information about the price of each ZoomInfo Plan.

It’s their policy not to give you any trial or pricing information until you schedule a demo with an account executive.

However, I’ve found that the ZoomInfo SalesOS offers 3 main packages + 2 free trials:

1. ZoomInfo Copilot Pro
2. ZoomInfo Copilot Advanced
3. ZoomInfo Copilot Enterprise
4. ZoomInfo Free Trial
5. ZoomInfo Lite (Community Edition)

You might think that ZoomInfo doesn’t offer a free trial, but it does, and there are 2 ways to use it for free:

1. ZoomInfo Free Trial
2. ZoomInfo Lite (Community Edition)

4. ZoomInfo Free Trial

Before purchasing an annual subscription, you must schedule a demo call with a ZoomInfo Sales Development Representative.

During this call, they explain and show you all the interface, details, and usage nuances you need to know about ZoomInfo to get the most out of it and give you time for some Q&A.

After this, you get an email with confirmation and ZoomInfo login information.

Follow the account activation instructions to start your ZoomInfo free trial.

Users can search the entire ZoomInfo database and download up to 10 contacts per month at no cost.

The only thing you give in return is your email contact book, headers, and signature blocks from received emails.

Apollo.io

Compared with ZoomInfo, Apollo’s pricing is also transparent and embraces low-barrier adoption with a free forever tier that provides basic access, which is ideal for testing and validating/or not the tool.

If you choose to be billed annually, Apollo pricing starts at $0 to $99 per user/month with a 20% discount.

---

The pricing model is justified for both tools. This makes your decision-making process less painful.

Compared to other scraping tools, the pricing may be overpriced for many small and medium businesses and companies that don’t need the daily credits and features for lead generation.

Let’s say you go with ZoomInfo. Then, you must pay an annual subscription exceeding $15K.

It’s right that this pricing may not be for SMBs or start-ups, but if you’re a large-scale enterprise with the budget to spend on this tool, go ahead!

But let’s say you only need the lead data lists in CSV, and that’s all.

Then, don’t hesitate to try other tools like LinkedIn Sales Navigator + Evaboot.

It’s a cost-effective duo for lead list enrichment.

You can scrape your prospects’ emails and phone numbers for $199/month ($1788/year) using a LinkedIn Sales Navigator and include people from your network.

Alternatives: LinkedIn Sales Navigator & Evaboot

If you still have second thoughts, I recommend testing Apollo.io and ZoomInfo alternatives.

LinkedIn Sales Navigator and Evaboot offer powerful lead generation and prospecting solutions.

With LinkedIn Sales Navigator, you can find prospects and companies that match your target profiles using advanced filter searches such as job title, company size, and connections.

Moreover, you get a set of key features, such as:

• Unlimited searches: Perform unlimited searches using extensive criteria.
• Advanced filters: Access better and more advanced search filters than LinkedIn’s free version.
• Lead Suggestions: Receive suggestions for potential leads.
• InMail Communications: Contact prospects directly through LinkedIn InMail.
• CRM Integration: Integrate seamlessly with your CRM system.

The cost of Sales Navigator depends on your subscription plan:

• Sales Navigator Professional: $99.99 /month
• Sales Navigator Advanced: $149.99 /month
• Sales Navigator Advanced Plus: custom pricing

After you’ve all the lead and company lists, download the Evaboot Chrome extension to export all your lead data.

This smart LinkedIn Sales Navigator scraper and email finder extracts, cleanses, and improves your lead list contact data with one click.

It’ll double-check your leads to show you if they match the search filters you selected and reduce the false positives in your Sales Navigator searches.

This is a cost-effective and bold tool.  

You can scrape your prospects’ emails and phone numbers and download clean lead data for $199/month ($1788/year).

That being said, lead data is not static.

B2B data decays by 2.1% per month, meaning 22.5% of your exported leads could be outdated within a year. Job titles change, companies evolve, and outdated information leads to wasted outreach efforts.

To solve this, Evaboot offers URL Enrichment: a tool allowing you to upload Linkedin URLs stored in your CRM to enrich your LinkedIn contacts with Sales Navigator data.

How it works:

1. Log in to your Evaboot account and go to the “URL Enrichment” feature.
2. Upload an old list of LinkedIn or Sales Navigator URLs.
3. Name your CSV file
4. Launch enrichment.
5. Wait a few minutes while the data updates, then download your refreshed list as a CSV file.

And here you go!

We recommend updating your lead lists every 3-6 months to maintain accuracy. This ensures your database stays fresh, relevant, and effective—so your sales efforts never go to waste.
