B2B social selling review methodology: desk research

This B2B social selling review methodology outlines a desk-research approach to assessing LinkedIn Sales Navigator Core for a single seller working with English business accounts. The result is a desk-research shortlist, not a recommendation: current records describe the product, but no hands-on or commercial evidence exists.

What to take away

Reviewer, date and conflicts

The sellerpresence.co.uk editorial research desk reviewed public sources on 5 September 2026. No named human reviewer has been appointed, which fails the publication gate. The desk received no payment, licence, trial, briefing, affiliate commission or supplier access. No employee or customer was interviewed.

The candidate was selected because LinkedIn publishes a current first-party record for the exact Core edition and the use case requires individual account research inside LinkedIn. Other editions and competing products are outside this exercise. This narrow selection cannot support a market ranking.

Evidence and scoring rules

Each requirement receives one evidence grade: absent, supplier-stated, documented, or buyer-tested. A separate pass or fail is used for mandatory legal, security, account-control and commercial conditions. Scores cannot rescue a failed gate.

The Sales Navigator comparison page, updated by LinkedIn on 1 July 2026, presents Core for individual sellers and documents search and messaging functions. This establishes the supplier's stated edition boundary. It does not show that records are complete, searches are appropriate or messages produce sales.

Four review tests

First, define ten synthetic account questions, such as locating a role within an agreed geography and excluding a known mismatch. Record the expected query, permitted data and acceptance rule before a trial. Search quality remains unscored because no Core account was used.

Second, test control rather than volume. Verify login protection, saved-item ownership, export boundaries, withdrawal of access and deletion of test material. The NCSC's UK supplier assurance questions provide prompts on governance, incidents, personal data and independent assurance, but the supplier must answer for the contracted service.

Third, test an outreach decision without sending to a real person. The reviewer should document purpose, lawful basis, transparency, message route, objection handling and suppression. The ICO's B2B marketing guidance explains that PECR treatment differs by subscriber type and that UK GDPR applies when a business contact is identifiable. Qualified advice is required for the actual design.

Fourth, check platform conformity. LinkedIn's prohibited software record says it does not permit third-party tools that scrape or automate activity. Any proposed extension or agency workflow must be identified and checked before use. This review did not inspect browser extensions or supplier processes.

Preserve a reproducible review pack

The eventual tester should retain the requirement version, candidate edition, account role, settings, synthetic inputs, expected results, actual results and dated evidence. Each failure needs a severity, owner and retest decision. A screen recording without those identifiers may show an action, but another reviewer cannot reproduce the finding.

Commercial evidence belongs in the same pack, not blended into product quality.

Obtain a written quotation for the chosen term, user count, tax treatment, support and implementation. Record optional costs separately. If you compare another edition, use identical purchasing assumptions and show the raw result before applying any weight. A trial offer or list price seen on a different day is not a like-for-like total cost.

Desk finding and missing evidence

Core is documented as a plausible candidate for one individual who needs LinkedIn-based research. It has not passed functionality, data, continuity, value or support tests. There is no buyer quotation, contract review, security response, test log or comparison with an alternative.

Keep the purchasing decision on hold. A named reviewer should run the scripts in the proposed edition, preserve actual results and obtain specialist privacy, cyber-security, procurement and commercial sign-off. The final record must name the tester, configuration, sample, failed cases and conflicts. It may conclude only for that setup and date.

Before you act

Common questions

What evidence grade was given to each requirement?

Each requirement receives one evidence grade: absent, supplier-stated, documented, or buyer-tested. A separate pass or fail is used for mandatory legal, security, account-control and commercial conditions. Scores cannot rescue a failed gate.

Why is the purchasing decision on hold?

Core has not passed functionality, data, continuity, value or support tests. There is no buyer quotation, contract review, security response, test log or comparison with an alternative. A named reviewer should run the scripts and obtain specialist sign-off.

What should the eventual tester retain in a review pack?

The tester should retain the requirement version, candidate edition, account role, settings, synthetic inputs, expected results, actual results and dated evidence. Each failure needs a severity, owner and retest decision. Commercial evidence belongs in the same pack.
