I have posted this on my twitter page, but due to space limitation, I thought I would describe it better here.

I got asked few times if building inbound links via posting comment on blogs works well? I always mentioned that its not a good idea unless your link is relevant and useful – as the Big G has spent lot greens to track such practice. Well, it is now official and Google have just recently posted that they are actively seeking out comment spammers and punishing accordingly.

I will have to come out honest and mention that I did put my websites links in comments but only if I thought it was appropriate and I always disclosed that it is my own website – rather than acting as a regular visitor referring to a site.
