I have come accross a good opportuinity (or so i think) to create a high quality backlink. A friend of mine has a pr3 web site which he is not usiong for organic traffic, just to have an online presentation of his company. And he gave me the permission to place backlink to my site. Please note that his site is about food product and my site is completly different niche: games. Currently the site has no links to other sites at all. So here comes the questions. 1) My site is a blogspot one month old and just started to create backlinks. will it be useful to place a backlink to the pr3 site? Also there is a catch. I must place the link in a place that is not actually visible as it is not related to my friends product at all. will it be ok if i place it within comment tags in the html code of one of the pages? for example<!-- website address --> 2) could i put backlink for 2 of my sites or it would be better to put only one backlink? 3) Any way to make those backlinks follow? Looking forward for your reply!
