Frequently asked questions
Do I need to pay to start?
No. The extension is free to install and use, and every ranking page and free tool works with no account at all.
Is it legal to study competitors like this?
Yes — everything here is published publicly by the stores themselves. Studying a competitor is normal business research. Copying their copy, images or brand is not, and that is a line worth keeping.
