The biggest marketing channel shifts
Meta Ads grew the fastest. Share of attributed revenue rose from 12.3% to 16.8%, a 36.6% jump month over month. This was the largest gain across any channel in the dataset.
Organic Search dropped meaningfully. Share fell from 12.0% to 10.0%. This continues a broader pattern as Google's AI Overviews and zero-click results compress organic CTR for product queries.
Direct traffic dipped slightly. It moved from 15.6% to 14.6%, likely a mix of real shifts and attribution noise from missing or stripped UTMs.
How ThoughtMetric measures this
When channel mix shifts, last-click reporting often hides what is driving sales. A customer might see a Meta ad, leave, then return through a Google search and convert. Last-click hands Google all the credit.
ThoughtMetric uses multi-touch attribution to credit the full journey. Pixel-based tracking and server-side tagging capture every touchpoint, configurable lookback windows from 7 to 90 days set how far back credit gets assigned, and post-purchase surveys confirm what customers say drove their decision.
That matters when reading a number like Meta's 36.6% jump. Multi-touch shows whether those impressions are driving net-new sales or assisting conversions other channels would have closed anyway.
