I bought it. My indexed pages went from about 900 to over 16,000 in about a month, and rankings seem to have climbed as well.
I am fellow user of vBSEO and i would recommend it to all, i installed and within a month or so i had already obtained a PR 3 ranking and 10,000 pages indexed in Google. tstaut how did you the DP Keyword Ranking tool to track indexed pages?
I use www.marketleap.com for that. Here's their search engine saturation tool: http://www.marketleap.com/siteindex/default.htm
Ugh - not this again. Ive posted on this a few times. You dont need it. Its icing on the cake at best. Focus your time and energy on getting links to your site and building content - you'll tdo better.
