Update

Well thats funny... @merrillg pointed out this is the data from the anchor text tab in the links section... makes sense its there considering it is anchor text but it shows in the keywords feed and not the keywords section which is where i got confused... I was wrong about it not being published anywhere else but this data is still pretty important... I cant believe I didn't notice that tab before... I guess I was distracted by the link data... sorry :(

Original

The keyword data that Google Webmaster Tools shows you is only part of the data that exists for your site... its up to 200 internal keywords, this comes from your pages and you can manipulate it based on the keywords you use in your content. But thats not whole story, what about that all important anchor text? Now of course you could go look at Open Site Explorer but wouldn't it be great to see what Google sees as your anchor text? I found the other keywords, the external keyword data hiding in a little known feed in webmaster tools... now aside from this guy who sounds a little like a consparicy nut and a short mention in the feed documentation nobody is talking about this data... Unfortunately i couldn't get pass through authentication so you have to put in your password but thanks to my new extension SEO Site Tools for Google Chrome you can navigate this data all from the safety of your favorite browser :)

heres how easy it is to get the data... open the tool from the Page Terms / Tools section

put in your login and it will present you a list of sites associated with that email addresses Google Webmaster Tools... choose one and you will see something like this
it will show you up to 100 external keywords... but what is this data that is published nowhere else any why is it so valuable? well lets take a look at bit of the list from my blog...

you know how sometimes when you do a search and look at Google's cache and see that "These terms only appear in links pointing to this page" thats what this keyword data is... its the external keywords Google has associated with your site... when I searched for some of the unique ones like "this feed is from my technology blog"
my site was the first result... i append that text with a link back to my site at the end of my rss feed so if someone republishes my content i can get credit for creating it... so the scrapers are sending that anchor text back to my site and whats even more interesting is that some of these keywords are from links that are no-followed so it might be that those links while not passing juice are passing something possibly even more valuable... their anchor text

the tool is still super beta and has some errors so please send me feedback to the email provided in the tool with any ideas/thoughts you may have about this very interesting data feed thats hiding in the webmaster tools data feed

again you need SEO Site Tools to get to this data and aside from doing some HTTP Gets yourself i know of no other tool that shows users this data

Update

i found some screen shots of the old tool on SearchEngineLand before it was removed

UPDATE:

The dashboard below is great but if your trying to do some on-page analysis you need a good SEO Toolbar like my newly released SEO Site Tools to help you with your work... and if you interested in your external anchor text you should defiantly run on over are read about the keyword data I found in Webmaster Tools that is published nowhere else...

i find myself constantly wanting to have one place as a jumping point for me to review all my website stuff and the way chrome does bookmarks makes it where clicking to this post is actually faster(at least for me). but i figure this is one place to start from then i don't have to go looking through all the bookmarks. ill add more items here as i find more tools that i find useful for SEOs and Webmasters


SEO Site Tools is my Google Chrome Extension with over 21,000 users 
im sure you would love it too... try it today

so i was reading the google analytics blog as i often do and they have this awesome new tool for visualizing your websites analytics data and keywords so lets get into what these way cool tools do (the tool is here but read the article cuz i spent some time on it)

first at the bottom you get a timeline so you can see the volume of traffic your site has been receiving and colorize this ribbon timeline by bounce rate. its cool to be able to see how your content starts being read more or single view articles turn it more red
this is also cool because you can view what pages drive the most traffic and how the bounce rate changes from page to page (if your colorblind thats cool too they got a button to fix the contrast for yall)
you can see a little better here in this shot how the bounce rate changes from page to page and how some pages are much more popular then others. heres the little video that they put out to demonstrate the tool.



then they have this cool keyword visualization tool that shows keywords and how they relate to each other and a few different options to color by. i like either time spent on site or bounce rate to see what words seem to keep peoples interest longer or drive them away faster
you can see how some keywords are red and threw more bounces and then my linkbait for embedding your Google profile social icons and the Google profile badge have green text showing that they had visitors staying for a much longer period (this graph is colored by time on page) and again the cool demo video the juice guys put out



here is the link to the tool i hope you find it useful and liked the article... don't forget to re-tweet about it and let others know!
