How to enrich a B2B prospect database

A raw list of leads rarely includes what you need to contact them: no email, no phone number, sometimes not even a website. Enriching a B2B prospect database is precisely about completing these records with public information, so you can move straight into sales action without hunting down each piece of data by hand.

In this article, you'll see which information to add as a priority, which sources to use, and how to proceed step by step, from importing your list to exporting it to a CRM. You'll also see the rules to follow to stay compliant, as well as the mistakes that waste time or skew your results.

What is prospect database enrichment

Enrichment consists of completing a company record that has already been collected with public information useful for prospecting: professional email, website, phone number, professional profiles. You start from a basic piece of data (the name and address of a company, for example), and you add what is missing so you can actually contact them.

Let's take a concrete case. You have collected a list of one hundred accounting firms in a given region. Each record contains the name, address and a Google rating. This is useful for targeting, but not for taking action: you have neither an email nor a direct contact.

Enrichment goes through each record and looks for, on public sources, what makes it possible to take action:

a professional email, to write directly
a website, to check the activity and personalize your message
a phone number, to follow up by call
a professional profile, to identify the right contact person

At the end of the process, your raw list becomes a usable list, record by record.

What information to add to your company records

Four fields make the difference between a listing that sits idle and a listing that actually helps you prospect.

Professional email: this is the most direct channel for a first written contact. Without it, you depend on a cold call or a generic contact form.
Website: it lets you check that the company is active, understand its real activity and personalize your message. An up to date site with recent news is worth more than a Google Maps listing alone.
Professional profile: it identifies the right person to contact, for example an executive or a purchasing manager, rather than a generic switchboard.
Phone: useful for following up after an email that went unanswered, or for sectors where calling remains the default, like construction or trades.

These four fields are not always available for every company: some publish everything, others nothing. The goal is not to reach 100% completion, but to have enough information to act on the majority of your list.

Which public sources to use to enrich your data

To enrich a company profile, three types of public sources come up most often.

The company's official website: legal notices, contact page, sometimes an organisation chart. This is the most reliable source for the website and the generic email, and sometimes for the name of a director.
Online directories: professional pages, sector-specific listings. They often confirm the address and phone number already present on the Google Maps listing, and sometimes add a professional profile.
Maps and business listings: the primary source for address, phone number and opening hours, but rarely for email or professional profiles.

These sources are not equally valuable across all sectors. A law firm often publishes a complete organisation chart on its website, while a plumber may only have a Maps listing with a phone number.

The rule to remember: you can only enrich what the company has made public itself. If a company publishes no email at all, no tool will be able to make one appear.

How to enrich a list step by step

Once your list is collected from Maps or a directory, follow these steps to enrich it without wasting time:

Clean the raw list. Remove obvious duplicates (same name, same address) before starting enrichment. A duplicate processed twice wastes time.
Run enrichment on the entire list. The tool will analyze each company's website and go through the Contact, Legal Notice or About pages to find an email, a professional profile or a phone number.
Check the completion rate. Not all records will be enriched to the same level: some companies publish little information. This is normal, not a bug.
Filter according to your criteria. Keep, for example, only the records with an email or a specific sector, so you only work on a relevant segment.
Export to your CRM. A CSV or Excel export includes all the columns collected and enriched, ready to be imported into the tool you already use.

B2B enrichment remains governed by GDPR, even when the data is public. Three rules to follow before sending an email or a message.

Target relevantly. Only enrich records that match your offer: a sector, a company size, a specific geographic area. Enriching an entire list without filtering increases the risk of contacting companies outside your target, which is of no benefit to you or to them.
Respect the right to object. Every contact must be able to refuse to be contacted and be removed from your list quickly. Provide a simple way to do this in your messages.
Respect the terms of use of the sites you consult. Directories, maps and official sites have their own usage rules. Collecting public information does not exempt you from reading and complying with them.

These three points do not replace legal advice, but they cover the essentials of reasonable B2B use. For details on the applicable rules, you can check the FAQ.

Common mistakes when enriching a B2B database

Enrich without targeting first. Launching enrichment on an entire raw list, including entries outside your area or outside your sector, wastes time and credits on businesses you'll never contact. Filter by sector and area before launching enrichment, not after.
Ignoring duplicates. The same business collected from several searches (for example "plombier Lyon" and "plombier Lyon 3e") ends up duplicated in the list. The result: you enrich the same entry twice, and a prospect receives two messages if it lands in a CRM without prior cleanup. Deduplicate on name and website before exporting.
Overestimating the completeness of public data. Not every business publishes a visible email or professional profile. Expecting a uniform fill rate across all fields leads to disappointment. Some entries will remain incomplete simply because the information doesn't exist online.
Forgetting to check the right to opt out. Enriching an entry shouldn't make you forget that a contact who has already opted out must be excluded from your next actions.

Which tool to use to enrich your prospects

To avoid juggling between a collection tool, an enrichment service and a separate CRM, ScrapLift brings all three steps together in a single platform.

Collection happens via a browser extension that structures the listings visible on online maps and directories (name, address, phone, website). Enrichment then runs at your initiative: ScrapLift analyzes each company's website, in particular the Contact, Legal Notice or About pages, to fill in the professional email and public profiles.

Once the list is enriched, the built-in CRM lets you organize it without any intermediate export:

Custom tags per campaign or per client
Pipeline statuses adaptable to your process
A 360° prospect profile that brings together collected and enriched data
Advanced filters, for example to isolate listings with no email
Duplicate management

Moving to an external CRM is still possible: the CSV and Excel exports keep every column. The details of each feature are listed on the features page.

In summary

Enriching a B2B prospect database means completing company records already collected with the missing information: professional email, website, profiles, phone number. The quality of the result depends on the public sources available and on precise targeting, not on massive, blind enrichment.

Before enriching your entire database, test the method on a small list, around twenty records for example. You will quickly see the actual completion rate for your sectors and geographic areas, and you will be able to adjust your filters before scaling up.

If you want to try this out with no commitment, the free plan lets you collect an initial list and enrich it with an included volume of credits, before choosing a subscription if the need is confirmed.
