I just noticed that a lot of people don't know they can verify their domain with Google Search Console or Bing Webmaster and see which queries lead to their site and which web pages are linking to their website. You will probably be surprised that some random person on the other side of the world wrote a tutorial on their blog for your tool. You get this for free without selling your data, unlike with analytics programs. For backlinks, you can also use the free Ahrefs backlink checker, which is quite limited, though.
