Does SBI analyze each page as you write them to evaluate keyword density?

You write the page, and then click the Analyze It! button. It’ll check keyword density along with every other on-page SEO factor, and provide you with recommendations and a rating of how important the recommendation is.

The keyword density check is the best part of Analyze It, especially when you go back to edit pages. I’ll add some content, and then Analyze It reminds me that I need to add another occurrence of the main keyword (or take one away, if I removed content).

Are the step by step instructions what gives their sites the traffic boost or are there automated tools that help increase traffic? Thanks

All the SEO is automated, the link building is done by you. They do have Value Exchange, a program to help you get good contextual links from other sites. Value Exchange will automatically monitor those links and let you know if the other site removes theirs after a while (which, unfortunately, some webmasters will do).

So anything that can be automated is, while you have to do the bits that are best done by a human.
