Optimization Vs. Construction:
The Internet is a research medium, not an advertising medium. Search engines such as Google, Bing & Yahoo designed their search algorithms based on how medical papers are organized and cross referenced in a medical library.
The secret to search engine optimization is understanding how medical papers are organized and cross referenced and then building a web site based on that. That's 95% of the game. Time and time again I have people contact me asking to optimize their web site, which means manipulating the embedded search strings, which are called Meta Tags. I tell them they are wasting their time and money because their web site is constructed as an advertisement and not a research document. Manipulating keywords on a poorly designed web site will only increase traffic in a minimal way.
There are also other things to consider such as the name of the html files, the name of the pictures, written content, alt tags, your location and the demand for your products and services. These are all factors, which determine the amount of traffic you will get.
If your web site is not getting much traffic then most likely it needs to be rebuilt.
Exchanging Links:
NEW FOR 2011: Exchanging links with other web sites is now considered spamming by Google, MSN and Yahoo. You can link to unique content or people can link to your unique content but the links have to be references supporting the subject matter of your page. An example is talking about how to catch Walleye and then referencing the walleye fishing tips at my Walleye Heaven web site. Trading links and having links pointing at each other's home pages to artificially increase your link popularity is spamming and your web site will be penalized or even blacklisted.
