The SEM service of tradekey is far better than its SEO service. I used both of them. Being patient to start the service is very difficult for me because their SEO service which expected to be started in May as i given everything required to start work but the service started in August on google 2nd page. While The SEM service was started in few days. Which was a relief for me that there is something to work on. However, SEO was good and cheap but objectives can be achieved then and there with SEM service.
