How does MOZ assign a keyword to a page in the On Page Grades by Keyword Ranking

[nuash]

I'm in the beta analytics tool. In the On Page Optimization > On Page Grades by Keyword section, there is a Keyword column with a keyword assigned to each URL on my site.

How is the keyword that is shown here decieed upon? Is it simply based on a guess of the "best keyword" for each page based on kwp density and other factors?

Can I map a new keyword to each page? or at least to my top ten most important pages? I see I can check the grade for any keyword on any page here: http://analytics.moz.com/search/manage-page-grades/572409.326269. I want to map my top ten pages to ten keywords - can I save these changes in the system so I don't have to manually check a keyword/url match each time?

Welcome to Moz! Have you checked out http://moz.com/help/pro/on-page-reports? That can help answer some of your questions.

How We Generate Reports
The On-page summary automatically generates reports for any of your campaign keywords that rank in the top 50 of your primary search engine. The URL that it grades is the same URL that appears in the search results.

For instance, if you have 75 keywords ranking in the Top 50, you should have 75 On-Page Reports. This generation happens automatically within 24 hours of when your rankings are updated.

Also, don't forget that you can always manually generate reports for any URL and one of your keywords. Simply go to the Report Card tab in the On-Page section, and cut and paste or type a new URL into the URL drop box. Then select your keyword from the drop down and select "Grade My Optimization." After that, you can tell the Web App to start tracking that combination in the future, and you should start seeing weekly reports. I hope this helps!

hello! i have a beginner question. i am taking over seo duties for an existing site with an existing Moz account. regarding "on page grades by keywords" tool, have these keywords and URLs been assigned by us previously manually or are these keywords assigned by moz as a recommendation?

also, how can i delete these or change the keyword for that page? it seems it was a previous seo for my site that assigned these keywords. they are wrong, how can i now get a grade for a URL with the proper updated keyword?

The keywords are decided by what is showing in the top 50 results for that keyword. We have some more details about the On Page Grader at http://moz.com/help/pro/on-page-reports

nuash,

You'll notice if you hover over the little "i" icon next to the column heading "URL" with an explanation of how those URls are populated.  The URL and page title in that column reflect the search result for a keyword you've chosen for your campaign.  So, you aren't able to map a new keyword to the url unless you reoptimize or better optimize the URL for the keyword you want that URL to rank for.
