I take a non invasive, systematic approach with my SEO. Different to most SEO companies / freelancers I don't alter the original websites that are often a labour of love on the clients part. I rank my own sites for a clients keywords and then overlay their fully functioning website on top. This gives peace of mind (their website is still under their control) and makes it risk free (any manual penalty that could ever come to the website would just affect my site.) I operate on a monthly fee that can be cancelled at any time. (Meaning the client wont be locked in to larger contracts if rankings drop or they are unhappy in any way.) Prior to SEO work I gained my Bsc. degree at Birmingham University, UK along with acting as president of their chess Society (including a win against current world champion Magnus Carlsen) :) Please note that currently I am only taking clients of $1000+/£500+ month due to the quality of work I produce and the costs these incur.
