Finding Keyword & Niches to Target Using Spam Blog Comments

I came to a conclusion today, I'm not sure if this sort-of-method has been discussed here (or anywhere) before:

I'm getting 100+ spam comments on my major sites a day. Most of them are using keywords in their names, and of course the URL they want to rank. All I have to do is compile a nice list of keywords, load them up in a keyword research program and find some that are worth fighting for. This can be the first filter when you're looking for new niches and keywords...

And it should be easy to rank for these, I mean, if they're spamming their sites directly then I'm sure some advanced SEO will shoot you to top ranks in no time.

What do you think?

I think, to compile a sheet of keywords will approach semrush. Well, if you want to check your words for competitiveness and the number of requests, it is the best option. There's everything in one actually. Many ideas can tell you, because you can look at competitor's keywords. I always do that.

Blair I'll be honest, I'm not sure I understand everything you're trying to say. Possibly they're lost in translation But yeah, SEMRush is a wonderful tool to spy on competition! I have a monthly license. MajesticSEO and Open Site Explorer are also recommended.
