Position trend
How many places the product gained or lost on its keywords during the selected period.
For every keyword, the product's first and last capture in the selected period are compared, and the changes are averaged. Keywords with more search volume and relevance count more. Only keywords where the product was on page 1 at both captures are included, so a keyword it newly entered or dropped out of doesn't distort the number. "+3 positions" means the product moved three places up on average.
Higher is better — a plus means the product climbed.
