You do use WeBuildPages' great SEO tools, right? I mean, hey, they are free. Besides that, they give you all sorts of great info. I've been using some of the tools for a long time. I'd say how long if I really remembered, but I don't. Just know that I've used them for quite some time, and if you haven't been, you should really check them out.
Whenever I start to analyze a site for optimization, I always use both the Top Ten SEO Analysis Tool (I think it used to be called Cool SEO Tool), and the Backlink and Anchor Text Tool (I think it used to be called the Neat-o Tool). Jim has certainly improved the names of the tools, but whatever they are called, they give great info.
I use the Top Ten SEO Analysis Tool to do competitive research. It's a quick way to determine how far I might have to go to be able to compete with the top 10. Fairly often, backlinks are one of the things that a site is lacking in comparison to the competition. So, running the Backlink and Anchor Text Tool is a great way to get started on link research. If I need extra backlink information, then I move on to the Deep Link Ratio Analysis tool.
There are a lot of other interesting tools as well, but those three are the ones I use most often. Armed with all of the info from those results, I usually have a solid idea of what I need to do with an SEO campaign.
I frequently admit to my bad memory, and I rarely rely on my memory to go to a website. But for some reason, I've never had to bookmark the Internet marketing tools. I guess that says a little something about how much I like these tools.
