Hi I have recently purchased getskrill.com which will be an affiliation website to target people to sign up to skirl which is very similar to PayPal but offers prepaid master card service for a small annual fee. I plan on keeping the site fairly simple unique content but just need an idea which key words are the most important.
The keywords you want to use are related to the content you want to write (or already have written). If you are writing about the advantages of Skirl you can use "Skirl vs PayPal" or "Why to use Skirl" or "Skirl benefits".
