		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 largest CRM platforms, covering everything from forms and voice communications to live chat 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.

Frequently Asked Questions

What is attribution in digital marketing?

In online marketing, attribution is the process of connecting marketing results mainly conversions and sales to the marketing effort that drove them, 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 software solutions for marketing attribution for lead-focused businesses are ActiveProspect, Zoho, Klaviyo, WhatConverts, Everflow, Impact, and HubSpot. 

However, if you need a comprehensive performance marketing ecosystem that, in addition to marketing attribution, 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 all touchpoints contributed, albeit to a different extent, you can use U-shaped or W-shaped attribution.
