In all honesty, I had never thought in my SEO strategy to keep an eye on some backlinks that are "hot" for us because of high authority.
With BackLink Checker, I now have the possibility to receive an email, once a month (because I don't want more) that shows me the evolutions.
It's simple, intuitive and really convenient.
The icing on the cake would be that the solution finds the back link... maybe one day, Santa Claus will hear me ;-)
In short, this application does the job properly and a plus in the strategy of reference and netlinking: I warmly recommend.
