My personal feeling about term frequencies on pages is that it's like chasing your tail.  Whatever way Google uses term frequency measurements is so wrapped up with a bunch of other machine learning algorithms that you couldn't possibly come to any real conclusions about its employment as a stand alone factor.

It's time to jump off the frequency bandwagon. As Matt Cutts says, Google is moving from "strings to things"--meaning a more holistic understanding of the page is where things are going.

Your 301 redirect will take place on the server level and your nofollow will take place on the page level. The server is going to redirect the bot to the new resource before it gets to the nofollow. As far as whether you can use a 301 to escape a penguin penalty is the subject of substantial debate but it's generally not thought so. Here's one of the most authoritative and interesting threads on that subject: Google 2.0 - How To Recover.

As far as I know, there is no tool like that and it seems that it would be very well known and used if such a tool existed but you may be able to get some of what you need from semrush.com.

Studio,

There's noise that the low quality guest posting tactic is next to be targeted by Google so consider the quality of your posts and the quality of the sites you get your posts published.  That said I'm familiar with two services--Bloggerlinkup.com and myguestblog.com but I'm sure there are many more.

edit: myblogguest.com not myguestblog.com. Sorry.

Dana,

When you say "inherits about 72% of Page A's pagerank if no other links are on the page", I think that's where your understanding goes off  track....either that, or it's where mine goes off track, because my understanding is that the percentage of PR that is passed from one page to another page is based on an unknown "X amount", not on the linking page's toolbar pagerank.   I think is better to say ...inherits about 72% of the pagerank that page A is able to pass...---not 72% of Page A's pagrerank.  Does that make sense?

Beytznet,

You may want to try this wordpress plugin to do you redirects.  If you haven't already read it, here's Moz's best practices for redirection.  And on this page is a link to a tool that can generate redirects for you.

The thing is Wilkerson, if the only thing the site has going for it is that it can get a mommy blogger network to link to it, then you're also saying that there's nothing worthwhile about the site, its products, or its content.  Let me tell you, as soon as a whole bunch of links to your site from a bunch of profiles that are also creating links to a bunch of other sites who's only links are coming from the same mommy blogger network, you're going to be staring penguin square in the eyes.   If you're thinking about jumping into a link wheel or link network, think long and hard.  Ever wonder why all those "mommy bloggers" work off of free, expendable websites?

In that case, it certainly can change over night but usually, with a new page or a page with that doesn't get much traffic it can take a month or more.  It is often the case that the home page will be re-indexed more often than other, less trafficked pages on your site, so don't expect that when you see one page updated in the results that the other ones are right behind it.

Hi Premio,

Typically, your pagerank won't change as a result of on-page SEO.  Increases in pagerank are  typically due to back links and other offsite factors and changes in PR due to those factors may take many months to impact your tool bar pagerank.  But don't focus or Pagerank--focus on creating content and on reaching out to your audience with content that is shareable and helps them make their buying decisions.
