I noticed for my site that we are getting slightly different scores based on whether we submit pagerduty.com or www.pagerduty.com. We have it set up so that pagerduty.com does a 302 redirect to the www. The Voltmeter app should see both of these as a single domain.
The problems I have noticed:
* For pagerduty.com, the "Keyword Targeting" section shows: 1) moved, 2) permanently, 3) nginx. Looks like it does not follow the redirect.
* For the "Incoming Links" section, I get different results for pagerduty.com and for the www. Again, you should combine the 2 resultsets, as some people might link to the www and others to pagerduty.com.
* In the "Search Engine Index Inclusion" section, it says Pages Indexed by Bing: 68. We don't actually have 68 pages, so I don't see how this is possible.
