Zoho: an All-in-One AI-Driven CRM and Operating System for Business

Overall Traffic, Q1 2026	Traffic Dynamics, Q1 2026 vs. Q1 2025	2-Year Average Traffic Share by Channel
		Bounce Rate	Direct	Organic Search	Referral	Social Media	Mail	Paid Search	Paid Referral
67.47M	10.98%	27%	73%	20%	4.4%	0.5%	0.04%	1.32%	0.18%

Zoho is one of the biggest CRM systems, covering everything from forms to voice communications to live chats and beyond. The platform’s products are used primarily by businesses in sales, marketing, finance, HR, legal, IoT, and product management and developer platforms.

Attribution-wise, Zoho supports six attribution models:

• First-touch attribution – 100% of the credit goes to the marketing effort that brought a visitor to your website for the first time
• Last-touch attribution – 100% of the credit goes to the marketing effort that triggered the winning of the deal (for example, a call that preceded a sale)
• U-shape attribution – 40% of the credit goes to the first touchpoint, 40% of the credit goes to the last touchpoint, and 20% of the credit is divided evenly among all other touchpoints
• W-shape attribution – 30% of the credit goes to the lead creation touchpoint, 30% of the credit goes to the deal creation touchpoint, 30% of the credit goes to the deal won touchpoint, and the rest 10% are divided evenly among all other touchpoints
• Linear attribution – the credit is divided evenly across all touchpoints
• Time decay attribution – more credit goes to the recent touchpoints

Not only can you choose a matching attribution model, but you can also customize the U-shape and W-shape attribution by changing the percentage of the credit across touchpoints. So you can adjust the attribution split across touchpoints based on their importance in your marketing funnel.

For example, with U-shape attribution, you can increase the percentage of credit that goes to the last touchpoint to, say, 60% if you think it creates a better performance marketing model for your business. Likewise, if you’re creating the attribution model with Zoho for the first time, you’ll get an ROI estimate based on the last two months’ performance data.

How We Researched, Evaluated, and Ranked Marketing Attribution Software

When evaluating the marketing attribution software for lead-reliant companies, we relied on 24 months of performance data from SimilarWeb, including global traffic, U.S. traffic share, quarter-to-quarter traffic growth, and traffic distribution across direct visits, search engine traffic, paid advertising, and other channels.

Likewise, we’ve taken into account performance metrics such as average visit duration, pages per visit, bounce rate, and unique versus return visits to evaluate how valuable the marketing attribution software is for companies relying on lead flows. All platforms that focused exclusively on phone call attribution, without address lead attribution, were excluded from the list.

Here are the main steps taken when ranking marketing attribution software products:

• Keyword and market research
• Competitive landscape analysis
• Traffic and engagement analysis
• Geographic relevance
• Categorical organization
• Comparative ranking
• Manual quality review

Importantly, we didn’t leave it to numbers – we checked every platform manually to ensure it contains all announced features and functionality. Platforms that haven’t passed manual verification were also excluded from the list.

Why You Need More Than Just Marketing Attribution to Level Up Your Marketing

Connecting leads to marketing efforts is integral to understanding campaigns more deeply, but you need more than that for successful marketing and ongoing bottom line growth. Ideally, you need a comprehensive performance marketing ecosystem that tracks the customer journey from top to bottom and uses these insights to optimize lead distribution and increase the business or agent’s chances of closing the lead.

This is exactly why Phonexa was built. We have united all performance marketing tools under one roof, from our core lead module, LMS Sync, and phone call module, Call Logic, to six features for omnichannel marketing, so you can manage customers from one place with convenience. Hundreds of years of combined experience in performance marketing have clearly shown that switching between platforms, tools, and reports is a significant waste of time, effort, and money.

Phonexa has found great success with larger-scale businesses, including affiliate networks, lead generators, and advertisers managing hundreds of thousands of leads and phone calls daily. From finance to insurance to home services to solar, Phonexa is almost industry-agnostic as long as you need a single source of trust and insights for the leads and calls you manage.

Get started with Phonexa to convert customer journey insights into profits.

LMS Sync: The Core Module for Lead Attribution, Distribution & Tracking

With Phonexa’s LMS Sync, you get full visibility into the leads in your system, starting from a customizable dashboard where you place the most essential metrics – total revenue, net revenue, leads sold, EPL, etc. – and deeper metrics, such as revenue by channel, lead freshness, and more.

Among other things, you can see how many leads were posted, sold, rejected, and redirected, allowing you to focus on the most profitable leads, campaigns, and sources. For leads that haven’t made it to the advertiser, you can see why: send error, rejected, etc.

Then, within the same module, you can build a custom lead distribution system – a cascading ping tree distribution for direct touring to a matching business or a ping post distribution for offering leads to several competing advertisers.

Depending on your risk tolerance, you can also verify leads with the iClear module using parameters like phone number, IP address, ZIP code, and even industry-specific parameters, such as credit history. Altogether, a well-thought-out lead tracking and distribution architecture within LMS Sync ensures you deal only with high-quality leads while protecting you from low-quality, irrelevant, or fraudulent submissions.

Frequently Asked Questions

What is attribution in digital marketing?

In online marketing, attribution is connecting marketing results – mainly conversions and sales – to the marketing effort that drove these results, such as the publisher, traffic channel, ad, or even keyword that triggered a conversion or led to a sale. In practice, a marketing attribution model often determines which affiliate gets revenue for the lead, phone call, or sale.

There are around half a dozen attribution models, depending on which marketing effort is perceived as more valuable to the marketing result: first-touch, last-touch, linear, U-shaped, and more. For example, last-touch attribution means the last marketing touchpoint before a sale receives 100% of the commission.

What is the best marketing attribution software?

According to our data-driven research and comprehensive evaluation, the 7 best marketing attribution software solutions for lead-focused businesses are ActiveProspect, Zoho, Klaviyo, WhatConverts, Everflow, Impact, and HubSpot. However, if you need a comprehensive performance marketing ecosystem that, alongside marketing attribution, also covers the entire customer journey, Phonexa might be your best choice.

What is the best marketing attribution model?

The choice of a marketing attribution model depends on which credit distribution you think is fair for your business model. For example, if you think the last touchpoint is most important, you can give it full credit with last-touch attribution. If, however, you think it’s far more complex, with almost all touchpoints contributing to the marketing result, you can use a U-shaped, W-shaped, or any other customer attribution model.
