"I use it to replicate strategies that work"
finds lots of links
provides data about each one
lets you see what links work and what don't
no, to my knowledge
I'm not sure about SEO agencies or such, but when it comes to owners of small sites like myself, it's the only SEO tool you need. I'm not that keen on checking my rankings as I don't have that many keywords and I don't have to report to anybody on them. But backlinks... that's what I'm really looking into attentively. I use SEO SpyGlass to research both links to my site and competition backlinks. I like monitoring my own link progress with SpyGlass more than with Google Webmaster Tools because there are way more factors reported on, and SpyGlass keeps them better organized. I also use it to check my competitors' backlinks. I just see what me niche fellows are doing and replicate as much as I can.
