    SIte PR question

    I run a site with PR 7 (front page) and other page is PR 6.
    There a plan for new design, layout, platform (current is custom CMS, so should be new URL in the future), so what should i do to keep all PR ?
    I know about redirect, but how to do redirect from old page to new page (old page will be all gone when the new design out) ?

    for example (PR6 page) : domain.com/education.php?article=steps
    how to redirect to new page ?
    New page might no longer exit or replace with other stuff.

    thanks

    I'am not sure about redirecting old articles to new articles. But I would not worry about it.

    As for keeping page rank, theme, layout, colors, type of cms,,, does not matter. Where are your backlinks pointing to, the html root / or an /index.php file? Whatever your backinks are pointing to, that is where you want your new CMS setup as.

    A redirect causes a loss of some PR.


    Eric Enge: Let’s say you move from one domain to another and you write yourself a nice little statement that basically instructs the search engine and, any user agent on how to remap from one domain to the other. In a scenario like this, is there some loss in PageRank that can take place simply because the user who originally implemented a link to the site didn't link to it on the new domain?

    Matt Cutts: That's a good question, and I am not 100 percent sure about the answer. I can certainly see how there could be some loss of PageRank. I am not 100 percent sure whether the crawling and indexing team has implemented that sort of natural PageRank decay, so I will have to go and check on that specific case. (Note: in a follow on email, Matt confirmed that this is in fact the case. There is some loss of PR through a 301).

    You should also redirect the internal pages should you have a lot of deep links.

    More or less changing the theme doesn't matter. However, changes to the content and internal linking structure can cause fluctuations to the search engine ranking position.

    Because you don't want to lose PR, you might just convince you boss not to redesign and change CMS

    Hopefully your site is hosted on some flavor of Unix/Linux and Apache. If so then you should have access to an Apache module called Mod_Rewrite. This is your BEST friend when it comes to redirects... I'm sure if you've surfed SEO forums long enough you've heard of it... or it's files named .htaccess.

    Get familiar with this utility. It has a pretty steep learning curve because it's based on regular expressions, but if you play with it for 20-40 hours you'll start to get the hang of it.

    This tool allows you to drop text files named .htaccess in various folders on your web server. These config files contain rules on how to redirect and/or rewrite URLs. It is VERY powerful and VERY fast. Basically Mod_Rewrite gets to inspect every page request BEFORE Apache gets to see it. So you can set up rules that say essentially, "if the URL being requested matches this pattern then redirect the request to this other URL". Apache never even sees that request if a match is found.

    If you don't understand redirects then here are a few useful resources for both implementing 301 redirects and all the things you might want to consider for SEO and a site redesign.

    The 301 redirect is one option. Another is to try to replicate the old site navigation and page naming schema as much as possible (this will require the same file extensions as well)

    According to Matt Cutts there is some loss of PR through a 301.

    But it's o.k. in my opinion to take it with a grain of salt. Everything isn't so black & white when he comes to the Google algorithm.

    If you know anything about Google's PR calculation formula from their Stanford Whitepaper and patents, you would know already that if a page has a PR of X and 4 outbout links... that the page does NOT pass 0.25*X PR to each outbound link is many think it does. It's actually a little bit less than that.

    Since the beginning of PR, there has always been a damping or decay factor in the formula. This damping factor (while the formula has been modified over time to account for things like penalties, discounting of links, nofollow, etc.) likely STILL exists as part of the PR calculation. Originally they said the damping factor was around 15%. So if a page had a PR of X and 4 outbound links, only 85% of that pages PR is available to be split over the 4 outbound links (assuming they are FOLLLOW links)... so 0.85*0.25*X is actually passed out.

    With each hop, there is a decaying or loss of some portion of the PR (originally ~15%). If you think of 301 redirects as an additional hop, the slight loss in PR is likely due to the way PR is calculated... and specifically due to the damping factor in that formula. Makes total sense that there is some loss.

    This is the VERY reason that you should avoid stacked redirects like:

    Page A --> 301 redirected -> Page B
    Page B --> 301 redirected -> Page C
    Page C --> 301 redirected -> Page D

    It's much better to have:

    Page A --> 301 redirected -> Page D
    Page B --> 301 redirected -> Page D
    Page C --> 301 redirected -> Page D
