Update: Backlink Analyzer is free link analysis software which has probably the best feature set of any of the link analysis software products on the market.

Recently Shawn Pringle launched PR and link analysis software by the name of PR Prowler. The first edition was a bit bulky and slow, but recently he launched PR Prowler V2.0 which has many needed upgrades.

PR Prowler operates in its own browser window similar to OptiLink. OptiLink still has a few more features (such as showing link text), but PR Prowler allows you to search for backlinks and keywords as well.

When you use PR Prowler with the Google link:www.evilcompetitor.com function it will return their backlinks and allow you to manipulate them in multiple ways. PR Prowler allows you to organize the links by site or PageRank or by how much the link should boost your PageRank (estimated). The best part about PR Prowler is that it primarily operates in the background so that you can do other business while it is collecting data.

Any software which runs in the background, checks backlings to the full Google database search depth (1,000), and will sort the results by PageRank is easily worth well over $100 to most webmasters, but PR Prowler only costs $97. View the official PR Prowler website.
