301 redirect

Does it effect page rank

[ffctas]

Hi
I have three domain names that I will do a 301 redirect on to one of the domains(domain 1). Currently domain 1 and 2 have a page rank of 4 and domain 3 has a PR of 2. When all are redirected will there be a change in the rank of domain 1.
Thanks for any info.

Using a 301 redirect should transfer PR and increase the (real) PR of the pages of domain 1. However, the answer if the toolbar PR of (the default page of) domain 1 is increased by one or not depends on the details. If the PR4 pages are close to PR5 then this will result in a PR of 5. Most likely the tollbar PR will be PR4 because the toolbar scale is logarithmic and the log. base is >> 2.

Also, there are other effects which lead to a change in TollbarPR for a page (at the same time). Namely the PR of the 3 pages will change due to the following factors:
- a change of PR for pages linking to the sites
- a change of transferred PR through a change of the number of links on those pages
- a change in the PR algorithm (e.g. the damping factor)
- a change in the Toolbar scale

An ASP solution from:
attention-to-details.com/newslog/37v-0-redirects-on-an-iis-server.asp

<%
Response.Status = "301 Moved Permanently"
Response.addheader "Location", "http://www.yourdomain.com/newpageurl/"
Response.End
%>

Even better:

[too much information]

You can do it with ASP:

Response.Status = "301 Moved Permanently"
Response.addheader "Location", "http://www.newlocation.com/"
Response.End

*Dang! too slow

Here's a thread you definitely will want to read: Moving websites to a new central domain [webmasterworld.com] (msg #2, #4)

Consider this:

Doing a 301 redirect is the same as saying "this ressource is permanently moved to this other location"

Now this is fine when one page moves from one place to another or when one site changes the domain name. But, this is a special case - it's not a move of one site from one domain to another, it's a merger of three domains.

So your'e telling the world that:

- domainA.com is now permanently moved to domainX.com, and
- domainB.com is now permanently moved to domainX.com

...see? Okay perhaps not, but whatever domain should now be considered the "real" domainA, B, or X?

... a Search Engine just can't have more than one website, or page, on the same URL. One might or might not stay, the rest has definitely got to go. (not gone like "low PR", but gone like "zapped", "gone", "nowhere"). As you're giving ambiguous directions here, the decision of what will happen will likely also be ambigous. It's like your website has a split personality or something.

For this reason, i'll recommend you use a 301 for one-to-one relationships (moves) and use a 302 for many-to-one relationships (mergers, redirects of vanity domains, link redirects, etc.) - i know it sounds silly at first, but it took me a while to figure out, and now i even feel it makes sense.

Added:If you're moving a website frome one location to another, or just want to take care of the www/non-www problem, this is the thread to read: Site change of URL [webmasterworld.com] (msg #6 and up)

Not many ordinary webmasters will ever need to mess with these things - if you choose to do so anyway for some odd reason, you better do it properly. The "Update Florida" definitely hasn't changed this.

Be warned!

I did a 301 for one of my sites and it disappeared from SERPS (well from 5th for a phrase, down to page 32 and as good as dead)

I logged this with Google about a month ago, but had no response.

What irks me, is that I could have done all manner of blackhat stuff to redirect my users, but I thought "no, I'll do it the proper way, and hopefully Google will appreciate that".. now I wish I'd done it other ways, and kept my SERPS

geezajob,

Same happened to me.
I did a 301 redirect for one page to a brand new domain / server.
The old page was #5 for my targetted query. Google picked up the new URL and indexed it. After Florida, the new page was #42 for the same query.

The good news: The Page went up to #2 recently.

Maybe you should give it a little time.

regards
Martin

It takes some time to go back to normal
