How to see rankings for a group of keywords over time?

[mlenz]

I have around 1200 keywords in an seomoz campaign, chopped into various groups using labels.  I am interested in tracking how keywords perform over time, especially groups of keywords.  As far as I can tell, in the seomoz tools I can only see historical performance for a single keyword at a time.

• Is there a way to get a historical performance graph of more than one keyword at once?  We often run optimizations for sets of words, so it seems like you would have better stats looking at groups of words vs picking one at a time.

• Is there a way to export historical data for more than keyword at a time?  (So I could graph and analyze this sort of thing myself)

• Does anyone have other suggestions for tracking rankings in this way?

Thanks for any help!

This article might be able to help a little.  It does not use SEO Moz campaigns to track keyword performance but does discuss how you can crawl search results from google for a to group keywords and then pair those results with data from Open Site Explorer.  You would not necessarily be interested in the second part.  Perhaps the spreadsheets discussed in these articles can help?

The first article references the second and third article.  The second article talks about how to use spreadsheets to scrape sites (include google SERP).  The third article mentions automatically grabbing data once a mont or so.  Seems like you could get a solution for what you are looking for with these three articles.

I don't believe it's possible to see historical data for more then one keyword at a time.

You could export current data for your set of keywords with a given label every week or so to csv, combine the data and you'd have historical data going forward.  Obviously this is not what you are looking for but could help if there's no better option.
