We've worked to make it as easy as possible, and it's roughly laid out the same way as Google Adwords. Basically, you add in the target pages that you'd like to rank for specific keywords, and then you define which keywords you'd like those pages to rank for. You also assign a rough estimate of how much a visit is worth to each page, that way we can decide which pages are more valuable for you to rank higher and thus we'll allocate our link building accordingly.
If you so choose, you can also break them down into subcampaigns for organization purposes, but that's entirely up to you. The length of the process really depends on how many landing pages you have, but you can use our bulk importer if you have a whole lot of them.
If you're having trouble setting up your campaign for the first time we have a Getting Started Guide that should help you along.
After setting up your campaign you'd like a review to make sure you're taking full advantage of Link Emperor we will be more than happy to take a look and let you know if we see anything you can improve upon.
