I launched the new version of www.amplex.dk a week ago and are trying to optimize it for google. I am testing the phrase "street light control" because I asume that this will be used for one of our solutions.
I discovered a few great tools for optimizing. First this tool
The next analysis tool I use is to get information of how my site rate for at phrase against my competitors. For this I use the KeyWord analysis tool, written by McDar. This is a great tool which provides lots of information for optimizing for phrases.
To verify keywords on your pages, you can use the ABACUS TopWord 1.1 which is great for getting ideas for META tags etc.
