The tool is broken. For many terms they do not give suggestions for others, only one or two suggestions. In some cases, not even the searched keyword appears in the results. Does anyone know what the news says the google keyword tool Suggest?
Mine works perfectly. Why do you need Wordtracker for and pay an arm and a leg if you can use Google External Keyword tool... Much better and gives you more results. Wordtracker can only use overture and some others. Who anyways searches for these. Wordtracker is a money making story.
The tool looks fine with me. Try to put different variation of keywords so that you can also get more keywords suggestions.
It works for me all the time: https://adwords.google.com/select/KeywordToolExternal maybe you need upgrade your browser
