Does 301 redirect cause penalty

[Prime85]

Good Morning,

I am considering doing a 301 (permanent) re-direct of roughly 100 domains, split between my 3 main e-commerce sites.

Would taking an action like this put any of the 100 domains or any of the 3 recipient domains at risk of violating G's guidelines?

Thanks...

Yes in can be, depends on why you are doing so. Check out this video

Dear Prime85,

Could you say a little more about the situation? Do these domains currently redirect using a 302? Are you linking from a group of these domains to one site? Are they all on the same IP?

I agree with Alan that the intent is what really matters. Registering .xxx versions of your brand name, or common typos of your CDN is different than building c blocks for spamming purposes.

I would start with a small group of these sites working from lowest DA/PA to the highest, testing as you go. Again it depends on your intent and the state of these domains. Are they "real" sites or just domains snagged to redirect and redirect only?

Take it slow. test your way to an answer.

Thanks,

Jon T.

i am no expert but it may cause problems through my own experience. I have used 301 redirects in my htaccess file because i have lost thousands of links through a major problem that was caused through my hosting company. I have seen my page rank go down from page rank 4 to page rank 2 and today i have noticed i do not have a page rank.

I have posted a question on here to find out more about it, but as mentioned it may cause a problem.

Diane, the OP is talking about 301 redirects of entire domains, and I believe you've been 301 redirecting missing URLs from all one domain, correct?
