I exported my back links report from the Open Site Explorer toolbar as a CSV but the file it showed was only about 400 urls. The tool bar is listing over 1,200 links, so at first I thought maybe it was only exporting one link for each unique domain, but it only lists 200 or so unique domains linking to my site. I know it will only export 10,000 urls, but obviously I'm significantly below this level.

Here is a link to a competitors site which is having the same issue.
http://www.opensiteexplorer.org/links?site=www.zoobooks.comListing about 900 links and only generating about 500 in the CSV report.

Any help would be much appreciated.

Someone recently told me that using branded keywords extensively in your copy and titles may be unnecessary so long as you have a substantial catalog of back links containing keyword rich anchor text. Can I take this to mean I can privilege non-branded terms over branded in my onsite SEO efforts?

I know Google Insights gives this data, but the fact that it's relative to overall search requests make it very difficult to see anything other then obvious trends (Toys sell better in November, go figure?). Each query I've looked up[ is showing degradation over time, but I'm postulating that this has more to do with search volume increasing then with the volume of my queries decreasing.

I'm getting unusual swings in SERPS ranks from one day to another (I had several keywords ranked in top ten go to the the third or fourth page in a week). I knwo that there's always variation because of localized and custom search, but this seems to be something more.
