is it worted exchange link to new or low PR sites?? or i just fokus to an old and high PR site?? thanks sam
Helo Sam, Yes you can exchange links from new websites if they are related to your websites theme. Links from old and high PR websites helps a lot but they should be related to your websites theme.
I would not hesitate to exchange links with good content sites even if they have poor PR or is new They might turn out more successful than our sites
If the site is good and cached in Google then yes it's worth it. With good content and a good link strategy that PR0 may be a PR7/8 in a few months.
