I have heard a lot recently about Google changing the way it ranks a site based on how links are displayed. My main site has lost page rank, but I am working on this, however I have recently implemented Adsence ads on my blog which is a sub directory on my site - http://www.blog.ktectraining.com - does anyone know whether this will affect the page rank as I have currently no rank on my blog and need to improve this. I was also planning on implementing Adsence for search, but I may delay this

Thanks in advance
