I've known Michael for a few years, and I've learned a ton from his blogs. He really knows SEO and how to do things the right and honest way. No gimmicks. I'm constantly learning from him and amazed at his knowledge.
He has helped me twice with my website, and most recently he gave me a new wordpress theme. This was a huge help as it not only looks better and gives me way more flexibility, but already, within a couple of weeks, the hits to my website soared. He made my site mobile responsive and it was a huge help. He also taught me how to use some cool features.
I highly recommend him. I've recommended him to several friends.
