Going from position 14 to completely disappearing ?

I would start slowly building solely "branded links", stay away from anything that could be considered a "money term".  Once you have some trust and authority for your brand I think it becomes safe to sprinkle a few "money terms" amongst your links to give Google a pointer.  Alternatively don't do any link building and focus on producing quality, relevant content and links will grow naturally - then you don't have to worry at all!

Hi Harry, Partial anchor text is a way that someone would link to you, not what you publish on your site. It's not something you can control or influence by what you publish on your site, beyond the general site theme.
