Here's a g reat tip from Jayde Admin.
There's a lot to say for carefully targeted campaigns, but another strategy involves saturation. After all, in just about any drawing or contest, the person with the most entries has the best shot at winning, and online campaigns can work in a similar fashion.
The Search Engine Saturation Tool will let you know how many pages you (and your competitors) have indexed with the leading search engines. Just input the URLs, and you'll be on your way to understanding the odds and achieving /search engine success.
