Hi Bloggers.
Just reporting back about my seo learning curve,
Well something worked because we now see around 4000 visitors per month and growing fast
some one way links from a powerfull site or two, happy customers kindly leaving a link and a mention in an obscure forum somewhere, oh and a $25 dollar a day addwords campaign to find those customers in the first place.
Still not getting enough organic hits I am going to keep working on it, any suggestions welcome,
