When analyzing a Positions report in SEMrush, you may notice that there are times when a keyword will show up multiple times. What this actually means is that the domain is ranking with two different pages on the same results page.
Take a look at the URL column in the screenshot above. This was taken from adidas.com's Organic Positions report.
There is an example of Adidas's positions listing the same keywords twice. As you can see, the landing pages for these positions are different. This means that adidas.com has different pages in the 1st and 2nd positions on the results page after searching for "adidas."
