We ran Helium 10 and SoldScope side by side on 3,179 Amazon product-keyword pairs for two weeks. When both tools found the product, their exact daily positions matched just 19% of the time.

Does that mean one tracker is wrong? Across 69 products and five marketplaces, the tools agreed on the top 10 in 83% of cases where either placed the product there.
They also agreed on the two-week trend direction for 59 of 68 products.
In this video, I walk through the comparison, how rank trackers collect their data, and what happens when rankings stay stable.
I also discuss possible reasons for different results, compare search-volume estimates, and add a smaller DataDive cross-check on one brand.
My takeaway: look at the trend before reacting to a small daily rank change.
Moving from #75 to #50 to #35 tells me more than a small difference between two trackers on one day.
