I've spent the last 2 years of my life developing URL Profiler, whilst also running my web development agency Evolution. I'm a self-taught programmer and like most of us, a self-taught SEO.
Back in early 2012, for reasons entirely (ahem) unknown, some of my sites started getting manual links penalties... and then later hit by Penguin. It was not a good year.
There were so many(!) that manually reviewing the link profiles wasn't an option. I ended up developing a tool to help me with the process - what is now URL Profiler.
I never intended to release it, but I gave it to a few of my agency friends who were handling a lot of penalty work. It became quickly apparent that it was actually a viable product that other SEOs found really useful. So, here we are today.
Hmm...so, if I'm the developer, what's Patrick? The idea's man - well that's what he likes to think anyway!
Oh and if you ever meet him at the bar, he'll probably tell you he convinced me to release the tool. But to be honest, I got fed up with him pestering me, so to stop the stalking I asked him to come on board and help.
