Dont use it for SE submission as all major search engines will deny it. Also you dont have to ever submit a website to be indexed just get links from popular directories and good ranking sites and you will get indexed in a week or less. SEO software is good for general guidlines but there is alot of unknown algorithms that you can do nothing about that will determine your sites rank as well.
The only tools that are worth using are keyword research ones at WordTracker and KeywordDiscovery. Other stuff just allows you not to learn your job. Really.
I use Webposition Gold (v3) for evaluating my placement for keywords on SE's.. It helps.. BUT I think there are better alternatives that don't cost anything.. Another one you may want to look at is Google's Analytics.. is nice for stats and free.
I don't recommend using an automated software for submitions. I'm looking into some article submition software.
I used software only to check my rankings for keywords. But I noticed that most of them, including Webposition, give inaccurate results.
So now I manual check and it's pretty boring.
Anyone knows good soft to check ranking?
SEO optimization software will more or less bring some benefit to your website, but if it's not free, you need to think whether the income is worth the money or time you spent out or not.
