I just came across this website I thought was sorta cool and wanted to share with everyone, apologies to those already aware of it. For those who aren't, It's designed for SEO purposes but a few of the tools can be very appropriately used to conduct some reconnaissance on a target.
By supplying a URL to the site's 'Spider Test Tool', you can quickly pull:
All outgoing links from the site
The source code of the page
Key words and density <-- very useful in crafting custom password lists
In addition, the site provides a 'Server Header Response Code Check Tool', which allows you to quickly check the server repose codes of a single target, or a large number of targets, which can come in super handy.
Hope someone finds this useful.
