Link Juice Propagation Time

Lets discuss a case:

Your site is mentioned on a big PR7 charitable site for some charity work you did. When can you see the effect of this link on your site’s rankings on the search engine. When do you the link link juice of the site propagates to you.

Well, this happened to me about two months back. I immediately started tracking it so that I can get the answer for this question.

Link Juice Propagation TimeTwo of my small niche sites were mentioned on a PR7 charity site. My friend who works for the charity informed me about it. Both of my current sites were PR2.

Its been two months for the event and here are my analysis for the same.

  • I started seeing the benefit for the same from day 10th in SERPs. Even after the 10th day the SERPs were improving. After around 40 days the ranking stabilized.
  • The site which were already ranking on page three for a quite competitive keywords came up in top 10.
  • The site which was not ranking in top 10 pages (though the keyword was not as competitive as in the other case), the site didn’t come in top 50.
  • The keyword which was the anchor text for the link from the charity site was the one for which ranking improved most. But all the keywords “related” to that keyword have also shown traffic increase of around 20% each.
  • For the other keywords on the site, which were not related to the keyword in the anchor text of the link, there was hardly any difference in the traffic.
  • Even after two months, still both the sites have PR2
  • Total traffic improvement is around 45% for one site and around 32% for the other in last two months. I am assuming that the traffic will also increase in the third month.
  • All of the SERP changes are first seen in US based datacenters of Google and were very slowly propagated to other datacenters. It took around more than a month to see things on other datacenters what was visible on US datacenters.

I have posted my results here. Tell me what information can you grab from this study? Does this say something about the link juice propagation time? Is PR still the king?

    Within that 2 months period, there has been PR update(s). If the PR7 link that you received pointed to an internal page, then surely the PR of the internal page would have increased but not necessarily the PR of your homepage (depending how you’re linking throughout your site).

    Is the charity related to your niche in any way? If not, then it means that you do not necessarily need to have thematic links to improve your SERPs.

    It is good to know that anchor text can give a boost not only to the primary keywords but also to related keywords as well.

    I have said and repeated this many times though I am not guru in SEO. Pagerank is important for the starters. That is for the first 6-8 months when you are trying to establish your site. Once people know the site PR is not at all important.

  3. Fergal, Business Advice Forum responded on 14 Jul 2009 at 3:22 am #

    Your results show that the most important factors are quality and number of unique visitors. PR is not so important and your traffic and site’s success can improve even with a fall in PR. One one site I own, I’ve seen search engine listings for targeted keywords improve and traffic increase at the same time as a drop in PR.

  4. 46and47 responded on 14 Jul 2009 at 8:11 am #

    It tells me that charities are about to get a lot more volunteers :-)

    Seriously, thanks for posting these results. It’s an interesting case study.

    I’m most surprised by how long it took for the SERPs to change and then stabilize. I only check rankings once a week now but maybe that’s still too often.

  5. edoogg responded on 14 Jul 2009 at 10:14 am #

    Was this done by your friend at your asking? For the purpose of conducting a case study?

  6. Rahul responded on 14 Jul 2009 at 11:05 am #

    frankly i have no idea.
    i believe links are more important than PR.

  7. Zak Show responded on 14 Jul 2009 at 5:19 pm #

    What I can grab from this case study is that I need to build more strong backlinks to my niche websites, high PR links still works to get a high search engines results and improves ranking in SERPs. Another this is SE algorithms still low as it tooks more than one month to notice some changes.

  8. BecauseILoveJimKarter, :) responded on 14 Jul 2009 at 6:50 pm #

    Strange that the PR of the 2 sites remained what they were. But who knows, may be there wasn’t any PR updates during the time by the big G. Anyway, interesting case study. Thanks for sharing them and we truly look forward to more. Keep ‘em coming, Jim.

  9. marcus @make money online responded on 14 Jul 2009 at 8:29 pm #

    I think pr rank is overrated. I have seen many pr 2 sites out rank higher pr sites in google. More important than pr rank is on site optimization and the guality of the backlinks that you receive. The more anchor text backlinks you can get with your primary keywords the better your site will rank in google,

  10. Jim Karter responded on 14 Jul 2009 at 8:54 pm #

    av, the link was to the homepage and the charity site was not at all related to the niche of both of my sites.

    edoogg, it was not done by my friend. I did some social work and some donation to the charity and they updated it. My friend just informed me about it.

    BecauseILoveJimKarter, yes PR still remained the same even though there was a PR update in between. If I see any changes in the PR, I will update this thread.

    The only explanation I can think of it is that the actual PR got updated but Google did not want to show it in toolbar. That is why many people say that toolbar PR is delayed.

  11. Vasu responded on 14 Jul 2009 at 9:22 pm #

    Great post after long time!
    Thanks jim

    Still the PR hasn’t been updated for your websites
    So, the page rank might not be the king , but the authority and popularity of the site might have helped in traffic increase
    Google says that they consider more than 100 parameters other than PR while ranking

  12. Vasu responded on 14 Jul 2009 at 9:23 pm #

    how is infolinks ?
    are they paying frequently ?

    Good analysis Jim, thanks for the update :D

  15. Ash Nallawalla responded on 15 Jul 2009 at 12:59 pm #

    Toolbar PR has not been useful for some years now, even though a lot of people lust for more green pixels. Unless the niche sites here are in the same niche as the charity, don’t even begin to look for a correlation between increased traffic or PR.

    Also, the home page PR of 7 doesn’t make it a “PR7 site”. A lot of directories have a greybar on inner pages.

    So, all you got was one extra link, possibly from an unrelated niche. Get a few hundred more links and watch the green pixels increase.

  16. BecauseILoveJimKarter, :) responded on 15 Jul 2009 at 9:14 pm #

    Yes, seems the PR thing is not reason enough for a page/site to rank or not. For example, this blog ranks very high for terms such as- How To Make Money Online Blog yet it has 0 page rank, :) Way to go, Jim. He certainly knows and does other things that the average Joe doesn’t, :D

    I guess this “LINK JUICE” stuff really does work, but it’s sooo damn hard to get a good link in a high PR site :(


  19. Jim Karter responded on 16 Jul 2009 at 8:37 pm #

    Vasu, yes I agree. The consider many factors. But I think high PR link (like Pr7 to PR10) still matters a lot.

    Vasu, ya infolinks are paying every month properly.

    Ash Nallawalla: Point noted sir. Good to have your feedback.

  20. Shardul responded on 17 Jul 2009 at 1:03 pm #

    According to me the PR doesnot affect your rankings much unless your website is relevant to the keyword, but if a site has got a PR 7 it means it has some good quality backlinks and the page has good value in google. I have tried putting my sites on PR 4, 5 Pages and no effect is seen. So instead of the PR, please tell us about the number of backlinks to the charity site which linked to you and the report of that site in search engines.

  21. bharath responded on 18 Jul 2009 at 10:47 am #

    Thank you for the post. What I grab from this is

    1) I think Anchor text is important as usual. (For ex- if you search the word HERE in google you will find Adobe, as so many ppl give links with anchor text HERE to Adobe ” click HERE to download Adobe”

    2) Do good sites(charity, religious, education, govt sites) are good for links.

    3) Link juice Propagation time was slow. (One higher pr, old similar niche link doubled my traffic next day). Some times it takes time, some times its very quick, may be it depends on how many times the linking site is crawled.

    Jim, Keep posting interesting articles like this.

    I would say pagerank is not a king but yes it helps a lot in improving the site statistcs.

    I feel the benefit of link juice too, we web get index for several keyword that i want. thanks for the post.

    Interesting study. I’ve been wondering about this before, but never got a chance to do a test.

    I guess the best thing to do is to get that link and just wait — have patience. And the SERPs will improve.

  28. Webmaster responded on 18 Aug 2009 at 5:19 am #

    Its definitely good to be mentioned in a PR7 site. Be it on niche or not.
    In Google Webmaster Blog, there was a post regarding PR and SERP. It was mentioned there that PR does have an effect on SERP.

  29. MoneyMan responded on 18 Aug 2009 at 5:37 am #

    @Webmaster: Yes, you are right. PR has some influence on SERPs, definitely. But not huge.

    Thanks for the post! PR helps rankings but won’t make a big difference.

  31. Free Microsoft Points responded on 23 Aug 2009 at 1:32 pm #

    I’m in need of a PR on my sites. That’s always the hardest part.

  32. Free Wii Points responded on 28 Aug 2009 at 5:57 pm #

    I am sure that PR is king in terms of backlinks. Without backlinks you can’t go that far for SEO.

  33. Rohit responded on 29 Aug 2009 at 1:20 am #


    Toolbar PR is just a general indication of quality of page. The PR we should rely on is the main page PR which is not disclosed by Google. The reason behind the boost of your ranking is because the link you got from the site is a website doing a good deed to people and because of that it would have got 100’s of quality backlinks from very authoritative websites. Which means the charity website got lots of credibility and authority. Also do you mind telling use the extension of the domain of their website?
    So some of their authority is passed on your website, which is the reason for your ranking. Also try searching the anchor text of the link (the link you got from Charity website) in Google, you probably would be ranking at 1st position for that keyword.


  34. MoneyMan responded on 29 Aug 2009 at 6:09 am #

    @rohit: The toolbar PR isn’t really important. The real PR is only known to Google.

  35. American in Britain responded on 30 Aug 2009 at 1:11 pm #

    I had a similar experience when one of my blogs was linked several times from PR7 internal pages at the BBC. At the next PR update, the blog went from PR0 to PR4 though I cannot be certain the PR increase was as a direct consequence of the BBC links. More importantly, the blog’s SERPs ranking for many current affairs related terms appeared to increase significantly within a 30 day timeframe.

  36. Dentist St Petersburg responded on 01 Sep 2009 at 1:27 am #

    Page rank and ranking both are important. Thanks for information about link juice.

  37. Free Wii Points responded on 05 Sep 2009 at 12:37 am #

    PR of backlinks that are higher are definitely helpful in lots of ways.

  38. marcus@make money online responded on 07 Sep 2009 at 11:00 am #

    your rankings improved because you link to an authority site using your keyword as your anchor text. The fact that the site has a high pr ranking gives your site even more relevancy to Google.

  39. Swami responded on 21 Sep 2009 at 3:36 am #

    Still link is the key. I am wondering what will happen if the site has link from which is PR8? I bet digg is do follow which i will be able to see in Webmaster Tools

    Just wanted to share my own experience. I got a PR5 back link for my site of PR4. I started getting results within 4 days. My site’s rank was jumped two positions higher in the competitive SERP for the anchor keyword of link.

    I guess…. it varies from case to case.

    I need a PR7 link to my sites. That’s always the hardest part.
