Keyword research
Keyword research should be the starting point before any internet project is implemented. Keyword research will show if there is a large enough market demand to make a project feasable, and supply information on how much competition there is for any keyword subject.

Ebook-Software-Reviews - Keywords Analyzer Review: "Keywords Analyzer shows the number of searches, and how many websites are already targeting that keyword.
You can start with a keyword and dig down 10 or 20 layers and keep adding to your keyword list.
Keyword Analyzer will show you how many Adwords, Yahoo Search or Miva campaigns there are for a keyword.
This means if there are less than eight Adwords campaigns you can get on the first page. And if you are building sites primarily for Adsense revenue, and you see a lot of Adwords ads, you know you have a profitable keyword for Adsense"
