I have had a good online retail business for the last ten years - using mainly PPC marketing. However, despite having medical licences for our products (which treat Psoriasis & Eczema) we were cut from Google Adwords. Google have no appeal process and every communication came back with a standard reply which read basically as 'tough'!
So, I have been forced to look for non-PPC ways of marketing online. I changed our site to a WP as most SEO articles suggest WP gets higher visibility...
