Freshworks

Objective: Audit a B2B SaaS company's GA4 direct traffic by landing page depth, UTM tagging completeness, and mobile app referrer loss to calculate what percentage of direct visits is actually dark social.

You have been brought in to evaluate the inbound acquisition reporting for Freshworks' customer service and CRM product line. The quarterly dashboard shows 42% of inbound demo requests originating from 'Direct / (none)' traffic, leading leadership to believe prospects are spontaneously typing freshworks.com into their browsers. Your audit will isolate deep-URL landing traffic, evaluate campaign link tagging, and calculate the true dark social share.

Run three systematic diagnostics using Google Analytics 4 and spreadsheet reconciliation. You will classify landing page depths for direct sessions, audit UTM parameter integrity across email and shareable resources, and reconcile software attribution against self-reported survey responses.

How much of our reported 'direct' traffic is actually unmeasured word-of-mouth, and where is our tracking leaking?

Google Analytics 4/Dark Social Attribution/UTM Tracking/Hybrid Attribution

Before you start

What you'll need

—Access to a GA4 property with at least 1,000 monthly sessions
—Basic familiarity with GA4 Landing Page reports and UTM parameters

Dark Social: Website traffic arriving from private channels (messaging apps, email, Slack) where referral headers are stripped, causing visits to appear as 'direct'.
Deep Landing Page: A specific URL path beyond the root domain (e.g. /blog/post-title or /compare/product-a) indicating a shared link rather than a typed domain name.

The process

3 steps

Step 01 of 03

Direct Traffic Segmentation

Homepage visits with no referrer are often genuinely direct (bookmarks, typing the URL). In contrast, direct visits landing deep on product feature pages, pricing calculators, or specific blog guides are almost exclusively dark social: links pasted into WhatsApp, Slack, Teams, or email.

What percentage of 'direct/none' sessions are landing on deep content URLs (>2 directory levels deep) versus the root homepage, and how much traffic does this reclassify as dark social?

Google Analytics 4— GA4 > Reports > Engagement > Landing page (filtered by Session default channel group = 'Direct')

Procedure

Navigate to GA4 > Reports > Engagement > Landing page
Add a filter for Session default channel group exactly matches 'Direct'
Add a secondary dimension: Page path and screen class
Export the top 50 landing pages to Google Sheets and categorize each into Root (/ or /login) vs Deep Content (/blog/*, /features/*, /resources/*)
Calculate the ratio of deep landing page sessions to total direct sessions to estimate dark social volume

Sample output

GA4 Direct Landing Page Breakdown (Sample 30-Day Window):
--------------------------------------------------------------------------------
Landing Page Path                    | Sessions | % of Direct | Classification
--------------------------------------------------------------------------------
/                                   |   14,200 |       35.5% | Genuine Direct
/login                              |    4,800 |       12.0% | Returning User
/blog/customer-service-benchmarks-24|    6,400 |       16.0% | Dark Social (Deep)
/crm/pricing-calculator             |    4,100 |       10.3% | Dark Social (Deep)
/compare/freshdesk-vs-zendesk       |    3,900 |        9.8% | Dark Social (Deep)
/resources/cx-roi-framework-pdf     |    3,200 |        8.0% | Dark Social (Deep)
/product/omnichannel-suite          |    3,400 |        8.5% | Dark Social (Deep)
--------------------------------------------------------------------------------
Total Direct Sessions: 40,000 | Deep URL Dark Social Volume: 21,000 (52.5%)

Healthy

Direct traffic is segmented into intentional direct (homepage/app login, 30-40%) and dark social discovery (deep URLs, 60-70%), with reporting acknowledging dark social attribution.

Unhealthy

100% of direct traffic is treated as returning brand-aware users, ignoring that thousands of first-time visitors arrive via private link shares.

What this means

Over 52% of Freshworks' direct traffic arrives on deep URLs (like competitive comparisons and pricing tools) that no user types by hand. This represents 21,000 monthly sessions of unmeasured peer-to-peer sharing.

So what do I do about it?

Symptom	Action	Effort
Leadership treats direct traffic as organic brand equity instead of earned peer sharing	Create a custom GA4 Exploration segmenting 'True Direct' (homepage/login) from 'Dark Social Direct' (deep URLs) for all executive reporting	30 min
Deep comparison pages receive high direct traffic with low conversion due to generic landing CTAs	Add context-specific 'Share with your team' and tailored onboarding CTAs to high-volume deep landing pages	half day

YouYou can do this yourself, no engineering access required.

Step 02 of 03

UTM Parameter Hygiene

Clean URLs pasted into private channels lose their referrer header. Pre-tagging outbound newsletter links, social share buttons, and in-app share dialogs with UTM parameters forces GA4 to record the campaign and medium even when opened in a native messaging app.

Are outbound email newsletters, in-app share links, and downloadable PDF assets tagged with consistent UTM campaign parameters, or are untagged links leaking into direct traffic?

Google Analytics 4— GA4 > Reports > Acquisition > Traffic acquisition (filtered by Session source / medium containing 'email' or 'share')

Procedure

Inspect inbound traffic sources under Traffic Acquisition for missing campaign parameters (`(not set)` or `(direct)`) on campaign dates
Audit 5 recent email campaigns and product share buttons to verify all destination URLs carry `utm_source`, `utm_medium`, and `utm_campaign`
Check for parameter casing inconsistency (e.g. `utm_source=Newsletter` vs `utm_source=newsletter`) that fragments reporting in GA4

Sample output

UTM Parameter Audit Matrix (Recent Outbound Assets):
-----------------------------------------------------------------------------------------
Asset / Channel            | Destination URL Sample                | Status   | Issue
-----------------------------------------------------------------------------------------
Weekly Product Digest Email| freshworks.com/crm/new-features       | Leaking  | No UTMs attached
G2 Review Promo Newsletter | freshworks.com/g2?utm_source=Email    | Warning  | Uppercase 'Email'
CX Benchmark Report PDF    | freshworks.com/cx-report-2025         | Leaking  | Raw PDF link
In-App 'Share Report' CTA  | freshworks.com/s/cx25?utm_source=app  | Healthy  | Trackable link
Partner Webinar Invite     | freshworks.com/webinar?utm_medium=cpc | Broken   | Medium set as cpc
-----------------------------------------------------------------------------------------

Healthy

All owned distribution channels (email, PDF whitepapers, share widgets) use lowercase, standardized UTM parameters, capturing at least 80% of traceable private shares.

Unhealthy

Links are shared raw with no UTM tags or with inconsistent casing, causing 40%+ of email and referral traffic to collapse into (direct)/(none).

What this means

Outbound emails and PDF downloads are distributing raw, untagged URLs. When subscribers forward these assets via Slack or WhatsApp, 100% of subsequent click traffic is stripped of referrer headers and misattributed as Direct.

So what do I do about it?

Symptom	Action	Effort
Untagged newsletter and PDF links creating artificial spikes in Direct traffic on send days	Enforce a mandatory URL builder template in marketing operations for all email, downloadable asset, and PR links	30 min
Inconsistent parameter casing fragmenting attribution across multiple rows in GA4	Standardize all UTM values to lowercase in marketing documentation and configure GA4 lowercasing filters	5 min

YouYou can do this yourself, no engineering access required.

Step 03 of 03

Self-Reported Attribution Reconciliation

Digital analytics only captures click paths, while dark social decisions happen in conversations. Pairing GA4 channel data with open-text 'How did you hear about us?' survey responses reveals which untracked channels (podcasts, Slack groups, peer chats) are actually generating high-intent leads.

When demo requests and signups are cross-referenced between GA4 first-touch channel and open-text survey responses, what proportion of software-attributed 'Direct' or 'Organic Search' leads cite dark social word-of-mouth?

Google Sheets— Google Sheets (merging CRM lead export with GA4 UTM acquisition data)

Procedure

Export 100 recent demo form submissions containing both GA4 source/medium and open-text 'How did you hear about us?' responses
Flag all records where GA4 recorded '(direct) / (none)' or 'google / organic' as the source
Categorize the open-text responses for those records into: Peer Recommendation, Slack/Discord Community, Podcast/Event, or Unspecified
Calculate the Dark Social Discovery Rate: (Dark Social Responses / Total Direct+Organic Leads) * 100

Sample output

Attribution Reconciliation Summary (100 Sample Demo Requests):
-----------------------------------------------------------------------------------------
GA4 Source / Medium     | Form Survey Response ('How did you hear?')       | Real Driver
-----------------------------------------------------------------------------------------
(direct) / (none)       | 'Recommended in the SaaSboomi founder Slack'     | Dark Social (Slack)
(direct) / (none)       | 'Colleague sent me the link on WhatsApp'         | Dark Social (WhatsApp)
google / organic        | 'Heard Chris Walker talk about CX on a podcast'  | Dark Social (Podcast)
google / organic        | 'Saw someone post about your pricing on Reddit'  | Dark Social (Forum)
(direct) / (none)       | 'Bookmark / already use Freshdesk'               | True Direct
-----------------------------------------------------------------------------------------
Reconciliation Metric: 64% of Direct/Organic leads cited an untracked dark social source.

Healthy

Marketing evaluates acquisition using a hybrid model: GA4 tracks capture mechanics, while self-reported attribution informs demand creation budget.

Unhealthy

Budget is allocated solely on last-click GA4 data, starving top-of-funnel dark social channels because they show 0 direct conversions in analytics.

What this means

64% of leads logged by GA4 as 'Direct' or 'Organic Search' actually originated from word-of-mouth in private Slack groups, podcasts, and peer messaging. Software attribution alone was blind to nearly two-thirds of pipeline creation.

So what do I do about it?

Symptom	Action	Effort
Leadership considering cutting podcast sponsorship or community budget due to zero GA4 conversions	Present the hybrid attribution model showing that 64% of high-intent enterprise pipeline cites those exact community channels	30 min
Demo request forms use rigid dropdown menus that hide dark social channels	Replace dropdown 'Lead Source' fields with an open-text 'How did you first hear about us?' input	30 min

YouYou can do this yourself, no engineering access required.

Analyze your findings

What to look for

Deep URL Direct Spikes: Sudden surges of direct traffic landing on specific blog posts or tool pages indicate a viral share in a private Slack or WhatsApp group.
Missing or Inconsistent UTMs: Outbound newsletters or PDF downloads lacking UTM tags directly dump interested prospects into the direct traffic bucket.

Make the call

Your audit reveals that 60% of direct demo requests land on a deep comparison guide, and 70% of those buyers cite a private Slack community on their form. How should you adjust your marketing reporting?

Recommendation · Priority: High

“Segment GA4 direct traffic by landing page depth in all executive dashboards and deploy standardized UTM tracking on all PDF and email assets. Reallocate 20% of underperforming paid ad spend into community-driven content programs that fuel dark social word-of-mouth.”

Common mistakes

What trips people up

Assuming all direct traffic represents brand-loyal users who typed the URL. — Over 50-70% of direct traffic to deep pages is actually private link sharing where referrer headers were stripped by the sender's app.
Relying solely on last-click software attribution to justify community and podcast marketing. — Dark social touchpoints rarely generate direct clicks, but they drive high-intent buyers to search or visit directly later.

Sample output

DARK SOCIAL AUDIT & ATTRIBUTION REPORT: ZENDESK CUSTOMER SERVICE SUITE

1. Direct Traffic Decomposition:
- Total Direct Sessions (Last 30 Days): 82,400
- Root Homepage & Portal Logins: 31,300 sessions (38.0% - Verified Direct / Brand Recall)
- Deep URL Landings (/blog, /benchmarks, /pricing): 51,100 sessions (62.0% - Reclassified Dark Social)

2. Outbound Link Audit:
- 4 of 12 active email nurturing sequences lacked UTM tracking on secondary resource CTAs.
- All downloadable benchmark PDFs used bare canonical links, stripping referrer on PDF viewer clicks.

3. Hybrid Attribution Reconciliation:
- 140 demo requests analyzed: 58 logged as Direct, 52 as Organic Search, 30 as Paid.
- Open-text survey analysis revealed 71 of the 110 Direct+Organic leads (64.5%) originated from private Slack groups (Support Driven, CX Community) and peer recommendations.

Strategic Recommendation: Maintain community sponsorship budget despite 0 last-touch GA4 conversions, and deploy standardized UTM shortlinks across all PDF assets.

Success criteria

You're done when you can:

Direct traffic is segmented by URL path depth (>1 subfolder) to distinguish brand-recall visits from dark social shares
Outbound marketing links are audited for valid, lowercase UTM parameters across source, medium, and campaign
A dark social adjustment factor is calculated to re-attribute misclassified direct conversions to word-of-mouth channels

Key takeaway

You cannot force private channels to send referrer data, but you can unmask dark social by segmenting deep landing pages, maintaining strict UTM hygiene, and asking buyers directly how they discovered you.
