Is it a good idea to cross-link my websites?

[sbrault74]

I own multiple websites in the same niche but all are targeting a different sub-niche and different keywords.

Is it a good idea to interlink all my websites? Could there be some negative effects?

As long as the sites don't have penalties or too many bad (non relevant) links pointing at them you should be fine. What is the reason for this? are you trying to push PR to one site? If so... What does your linking profile look like?

If the new site will target the same keywords or if you are going to use the same exact text I would recommend doing a 301 redirect so that you can keep you link juice (authoritative qualities) and avoid duplicate content.

There's nothing wrong with Legitimately linking to relevant websites (yours or not)

SEOMOZ for example.. They link to all of their properties from here...

The only thing to look out for is site-wide links, or more links then what would be regarded as "natural"

Also, make sure your websites are all on unique C-class IP's or Google wont value the links from your other sites as much as it would if they were on unique C-class IP's.

If 10 sites have the same C class IP, they are most likely owned by the same person, therefor Google places less value on them

Ahh I see read this prior to my morning coffee...

Yes you are correct, don't know why I was thinking that the sites where going to be migrated... However, if 3 pages are on the 2nd page of Google for one keyword, doing a 301 redirect from 2 of the 3 pages to 1 page should help win.
