6 of the Best Marketing Attribution Tools in 2025

Every marketer faces one fundamental question that directly impacts ROI: which of your marketing channels actually drive results?

Marketing attribution tools are the only reliable way to answer this question. You can measure any number of different metrics and KPIs, but at the end of the day, the only way to prove which marketing channels are working is to tie them directly to your company's bottom line.

That's not necessarily easy, especially without the right tools. According to MMA Global's State of Multi-Touch Attribution report, 61% of marketers are dissatisfied with their ability to quantify the total impact of their marketing.

Marketing attribution tools provide reliable data that you can use as the basis for your marketing decisions. In the article below, you’ll find a list of the most popular marketing attribution tools on the market today.

Marketing Attribution for Google Ads

Every dollar you spend on ineffective Google Ads is a dollar that could have been spent on effective Google Ads. Marketing attribution allows you to identify your effective ads and shift spend accordingly.

WhatConverts can track every Google Ads lead back to the campaign, keyword and ad content—and unlike Google's built-in tracking features, it can do so even if Google Ads wasn’t the user's first click. Someone may find your site in organic search, leave, then come back later from a Google Ad. WhatConverts will still pass this along as a conversion in your Google Ads dashboard.

This is also a big deal for anyone analyzing ad success in the Google Ads dashboard. WhatConverts can pass along conversion to Google Ads even if the click wasn’t the first or last click.

This is how WhatConverts ensures Google Ads gets credit for any lead that used Google Ads as part of their customer journey.

Lead tracking is just the start. WhatConverts also provides detailed reports showing which ads, campaigns and keywords drive the most qualified leads and the most valuable leads. It’s easy to see which keywords to target in Google Ads to get the best ROI.

You can then click on the report to see the individual leads that make up the data.

Clicking "View Lead" allows you to go even deeper into the data to see chat transcripts, call transcripts and Customer Journey maps for each lead.

Marketing Attribution for Content Marketing and SEO

SEO marketers often struggle to measure the success of content in terms of leads or sales. It’s easy to track search rankings, but you should also be able to track the business impact of SEO and content marketing.

Marketing attribution isn’t just for paid advertising; it can attribute leads to website pages, blog articles, and emails. You just need software that can track any conversion action including phone calls, forms, and chats.

The WhatConverts Leads by Landing Page report reveals which pages are attracting your most valuable customers. If you know which keywords you’re targeting on each of these pages, you can make informed estimates about which keywords are attracting valuable leads.

WhatConverts also shows which page users were on when they started a chat or placed a phone call to your business. This shows you not just which pages convert well, but which pages convert your most valuable customers.

Marketing attribution can tell you if a blog article was part of the customer journey, and allow you to measure SEO success in terms of leads and sales; not just search engine ranking. The WhatConverts Customer Journey View can reveal when leads use the blog as part of their path to conversion. WhatConverts marketing attribution works for every channel and every lead.
