The Lean Lead-Gen Stack: Prove Your Marketing ROI on a Budget
Your B2B sales cycle is long and involves multiple touchpoints, making it nearly impossible to connect an initial Google Ad click to a deal closed months later. You're forced to optimize for top-of-funnel metrics like 'leads,' potentially wasting your budget on campaigns that generate activity but never translate to real revenue.
This playbook details 'The Lean Lead-Gen Stack,' a highly cost-effective setup designed specifically for SMBs to solve the attribution puzzle. By integrating Ruler Analytics to track the entire customer journey with Zoho's generous free CRM, you can finally connect marketing spend to sales revenue. This stack closes the loop, allowing you to see exactly which ad campaigns, keywords, and channels are driving your most valuable customers, all without a high monthly software bill.
Expected Outcomes
- Accurately measure the ROI from every marketing channel, including Google Ads.
- Connect every closed-won deal in your CRM back to the specific marketing campaign and keyword that generated it.
- Stop wasting budget on ad campaigns that generate low-quality leads who never convert.
- Optimize your marketing spend for bottom-line revenue, not just vanity metrics like clicks or leads.
- Gain a true, data-backed understanding of your Customer Acquisition Cost (CAC).

The Workflow
Integration Logic
-
Ruler-to-Zoho Lead Journey Connector
When a new lead submits a form (e.g., a MailerLite form) on your website, Ruler Analytics captures the conversion and all associated marketing attribution data (source, medium, campaign, keyword, etc.). Ruler then sends this complete data package via a webhook to Zoho CRM's API. A new lead is created in Zoho CRM, and custom fields are populated with the specific attribution data from Ruler. Subsequently, a Zoho CRM workflow rule triggers an API call to MailerLite, adding the new lead as a subscriber to a designated group for targeted email campaigns. This creates an end-to-end data flow from first touchpoint to CRM record and email marketing segmentation.
