Suppose you see differences in session numbers between Amazon Seller Central and Intentwise (for example, in the product\_summary table). In that case, it’s usually due to how Amazon reports sessions across different report types and time ranges. ### Why This Happens #### 1. **Different Report Definitions** - **Sales and Traffic by ASIN** includes all ASINs with at least one page view, even if there were no sales. - **Sales and Traffic by SKU** includes only SKUs with at least one sale. Because of this, the ASIN-level report often shows higher total sessions than the SKU-level report for the same date range. #### 2. **Daily vs. Monthly Report Behavior** - **Daily SKU reports** count sessions only on days when a sale occurred. - **Monthly SKU reports** include all days with traffic, even if no sales occurred. As a result, summing daily SKU sessions may not match the monthly SKU or ASIN-level totals. ### How Intentwise Handles Sessions Intentwise sources session data in the `product_summary` table from the **Sales and Traffic by SKU** report. To ensure accurate comparisons: - Use the same report type (SKU vs. ASIN) on both sides. - Match date ranges and reporting frequency. - Remove duplicates if exporting manually from Seller Central. ### Common Scenarios | Situation | Likely Cause | Tip | | --- | --- | --- | | Seller Central total doesn’t match Intentwise | Comparing ASIN-level data with SKU-level data | Compare SKU-to-SKU | | Summed SKU sessions \< brand total | Daily reports omit no-sale days | Use monthly SKU or ASIN report | | Product Summary slightly off from API data | Different report endpoints used | Validate using “Sales and Traffic by SKU” | ### Key Takeaway Session discrepancies are expected when comparing across Amazon’s report types. Intentwise aligns with **Sales and Traffic by SKU** data to ensure SKU-level accuracy. For best results, always compare **like-for-like data,** same report, same level, same time range. - [Getting started](https://help.intentwise.com/getting-started?hsLang=en) - [Intentwise AI Gateway](https://help.intentwise.com/intentwise-ai-gateway?hsLang=en) - [Intentwise Ad Optimizer](https://help.intentwise.com/intentwise-ad-optimizer?hsLang=en#main-content) - [Account and Campaign Setup](https://help.intentwise.com/intentwise-ad-optimizer?hsLang=en#account-and-campaign-setup) - [Optimization](https://help.intentwise.com/intentwise-ad-optimizer?hsLang=en#optimization) - [Reporting](https://help.intentwise.com/intentwise-ad-optimizer?hsLang=en#reporting) - [Dashboard Overview](https://help.intentwise.com/intentwise-ad-optimizer?hsLang=en#dashboard-overview) - [Resources](https://help.intentwise.com/intentwise-ad-optimizer?hsLang=en#resources) - [Amazon DSP](https://help.intentwise.com/intentwise-ad-optimizer?hsLang=en#amazon-dsp) - [Additional Features](https://help.intentwise.com/intentwise-ad-optimizer?hsLang=en#additional-features) - [Walmart](https://help.intentwise.com/intentwise-ad-optimizer?hsLang=en#walmart) - [Criteo](https://help.intentwise.com/intentwise-ad-optimizer?hsLang=en#criteo) - [Instacart](https://help.intentwise.com/intentwise-ad-optimizer?hsLang=en#instacart) - [Intentwise Explore (AMC)](https://help.intentwise.com/intentwise-explore-amc?hsLang=en#main-content) - [AMC](https://help.intentwise.com/intentwise-explore-amc?hsLang=en#amc) - [Instructional Queries](https://help.intentwise.com/intentwise-explore-amc?hsLang=en#instructional-queries) - [Intentwise Analytics Cloud](https://help.intentwise.com/intentwise-analytics-cloud?hsLang=en#main-content) - [Kickstart Guide](https://help.intentwise.com/intentwise-analytics-cloud?hsLang=en#kickstart-guide) - [Configuring Reporting Tools](https://help.intentwise.com/intentwise-analytics-cloud?hsLang=en#configuring-reporting-tools) - [Configuring Data Pipeline](https://help.intentwise.com/intentwise-analytics-cloud?hsLang=en#configuring-data-pipeline) - [Data Sources](https://help.intentwise.com/intentwise-analytics-cloud?hsLang=en#data-sources) - [Looker (Google Data) Studio Tutorials](https://help.intentwise.com/intentwise-analytics-cloud?hsLang=en#looker-google-data-studio-tutorials) - [Intentwise Templates](https://help.intentwise.com/intentwise-analytics-cloud?hsLang=en#intentwise-templates) - [Intentwise Analytics Cloud features](https://help.intentwise.com/intentwise-analytics-cloud?hsLang=en#intentwise-analytics-cloud-features) - [White Label](https://help.intentwise.com/intentwise-analytics-cloud?hsLang=en#white-label) - [Intentwise Marketplace Intelligence](https://help.intentwise.com/intentwise-marketplace-intelligence?hsLang=en#main-content) - [Content Analytics (CA)](https://help.intentwise.com/intentwise-marketplace-intelligence?hsLang=en#content-analytics-ca) - [Share Of Voice (SOV)](https://help.intentwise.com/intentwise-marketplace-intelligence?hsLang=en#share-of-voice-sov) - [Frequently Asked Questions (FAQs)](https://help.intentwise.com/frequently-asked-questions-faqs?hsLang=en#main-content) - [Access and Setup](https://help.intentwise.com/frequently-asked-questions-faqs?hsLang=en#access-and-setup) - [Billing](https://help.intentwise.com/frequently-asked-questions-faqs?hsLang=en#billing) - [Platform](https://help.intentwise.com/frequently-asked-questions-faqs?hsLang=en#platform) - [Reporting](https://help.intentwise.com/frequently-asked-questions-faqs?hsLang=en#reporting) intentwise.com Help Center Copyright © 2026, Intentwise Inc.
