301 Redirects Pass Google PageRank & Signals in a "Couple Weeks"

SEOs and Webmasters always wondered how long it took for a typically site to pass along a PageRank value from one URL to another via a 301 redirect. Google's Adam Lasnik answered this question, saying only about a couple weeks.

In a Google Groups thread Adam says:

301s pass PR and related signals appropriately. Usually takes a couple of weeks for things to smooth out, though.

I was a bit shocked by the statement of just "a couple of weeks" for 301s to "pass PR and related signals appropriately." I always thought it was a couple months or more.

Well, maybe Google picks up the changes within a couple weeks. I.e. the time it takes to crawl the new information and URLs. But maybe by the time all this data is processed it takes longer?

But then why would Adam use the words, "for things to smooth out." Meaning, search results to smooth out.

He probably means throughout all the data centers.

In that group in particular Adam has to speak en masse from the casual blogger to the serious SEO so generalizations are the norm. However, my experience has taught me that a cross-domain 301 will take months like you said, and within the domain it can take as little as a few days to a couple weeks for the less crawled pages.

If only Yahoo were so efficient. It still takes over a year for any major site to switch domains.

If you got a 301 on a supplemental page, I don't think the transfer is that quick, because according to Matt Cutts, supplemental pages don't get crawled by Googlebot as often.

I switched my site to another host and was pretty proficient in my 301's and even now, a year later...I am still waiting for my pr3's and 4's to transfer over...still nothing yet.

I had just completed a series of 301 redirects for a client across 20 domains. It appeared that the PR transfer was instant for one of the target domains.. a couple notes: - all of the other domains where forwarded with a consistent url previously. - even though the other domains where mirrors of the primary site they still held [1-2] PR - the other domains passed an increase of PR1 to the primary domain, moving it from 2 to 3. I realize these instant results are not typical as I tried it on another domain that was not mirrored and it did not happen instantly.. My 2 cents!

I just did 2 redirects 301 on IIS from 2 pages with duplicate content to a third page. They all lost their PR for the moment (PR5 PR4 became unkanked). I'm waiting for an update of google.

How can i realize this 301 redirect on Apache? Something with .htaccess files?

Anybody knows if redirecting to site A an unrelated site site B will pass values to site A?

hi, I also did the same. redirected http://www.fileconvert.net (PR2) to http://products.softsolutionslimited.com (PR0 as of now). still waiting for Google to update. however, I will still use previous http://www.fileconvert.net for link building. but I believe it should not matter what url to use from now on. but better to use previous one as it is heavily spread across the web as compared to the new one.

I noticed that most of my main pages dropped from google SERPS. I immediately checked, and it looked like duplicate https: versions of the pages had been indexed (even though there are no actual https: pages on my site... freak google error?) anyway, it took a while, but i think i have covered all of my bases as to how to get the pages back on google SERPs. I've put canonical links on all the pages, things "look" ok in google webmaster tools, (besides the huge drop in traffic) and i have a 301 redirect in my htaccess file working to divert any requests for https: pages to http: pages. I requested reinclusion w/ google, as i thought that maybe i had done something wrong, but it just came back as "processed" a week ago w/o any info. I'm wondering If the https: / duplicate indexing is definitely the issue, and if so, am i going about it correctly to now just wait? The 50 or so dropped pages all seem to have an "https" equivalent when i look at which pages are indexed in google. It's been 4 weeks since my pages got "dropped" and 2 weeks since doing the redirect. Still in the dark. My site is almost 6 years old, and this is the first time that something like this has happened. If anyone has a thought on this, i'd love to hear, as 4 weeks w/o google is REALLY painful. thanks in advance - Kevin

I doubt this takes in to account the recently added caffeine to the indexing process. I accidently put a 301 on a page that ranked very well for a particular term and the page i 301'd this highly ranked page to was replaced in the SERPS within a couple of days. We actually just removed the 301 and did a couple other things, we'll see how long it takes to replace the "wrong page".

I am wondering what if I do anchor text link on a page of old domain site and use 301 redirect to a new url of a new website. What will happen? For instance this is my page of old domain with google PR 5 http://www.hnty.com.cn/intro5.htm on which I put on an article with link with anchor words. And meanwhile the page is redirected in 301 model to http://cheapjerseys.tk,a complet new site with PR 0. My question is: the PR 5 on the old page will be transfered to the new url?

I have a website, http://www.techrecipes.net , which is based on dokuwiki. Previously it was based on wordpress, and the URL structure is just different from dokuwiki (and my PR dropped from 4 to 3 in the process). I configured 301 redirect for inbound link to my previous wordpress posts to the equivalent dokuwiki page, but my PR is still the same after a few months :(
