Linked In

LinkedIn is where B2B identities live—make sure the URLs you store truly point to the right people and companies. Delpha's LinkedIn Finder and LinkedIn Validator keep your CRM aligned with canonical LinkedIn profiles by normalizing URLs, checking format quality, and surfacing the most relevant matches.

What we assess:

• Completeness: Is a LinkedIn URL provided?

• Validity: Does the URL follow LinkedIn's accepted format (no existence check)?

• Consistency: Does the input equal the normalized canonical form (e.g., people → .../in/, companies → .../company/)?

• Accuracy: Does the URL appear to match the provided context (person: first & last name, optional company; company: company name, optional website)?

What you get back:

• A normalized LinkedIn URL and quality scores for the checks above.

• When context suggests a mismatch or uncertainty, AI-powered recommendations: candidate profiles/pages with confidence scores, rank, and helpful details (name, title, location, description). If a company website is provided, we can use it to help identify the official LinkedIn page.

With LinkedIn Finder and LinkedIn Validator, your records stay clean, standardized, and tied to the right LinkedIn identities—boosting routing accuracy and downstream engagement.
