We have multiple full websites and are thinking about consolidating them into one. We have redirected one domain with great results in rankings. What about another or 2 more? I have heard this can be bad.
as long as you avoid trust and relevance issues you'll probably be ok. are the sites relevant to each other? are you doing a redirect where every url has an equivalent url with essentially the same content on the new domain? are you changing the urls other than the hostname?
hmm, yes, the urls would be changing...I've spoken with several people regarding this issue since I've made the post. They say it will have no benefit in terms of boosting a site's ranking after the first site merge...what do you think?
