TODAY'S TOP SEARCH TRENDS
In order to see what's catching people's eyes, I turn to Google Trends Lab. You can see what people are searching for most on Google. It's updated constantly. Take a look for yourself.
ONLINE ADVERTISING

I also use Visit Yahoo Search Marketing for advertising but get less traffic and have to monitor conversions more closely for accuracy. Yahoo is also a good tool but a little slower to get significant results, at least in the testing I have done for the last few months.
ONLINE SEO
SEO, short for Search Engine Optimization, is the process of improving the volume and quality of traffic to a web site from search engines via organic search results for targeted keywords. In other words, it places you higher in the search results without you being a paid sponsor. It's definitely a good goal to get higher organically for keywords related to your content and what you are trying to sell or promote. You can do this by providing relevant content, adding metatags to your site, linking to blogs, promoting your site, sending out press releases and/or hiring an SEO firm if you need help. If you can get high in the organic search, then you can reduce your online advertising spending and make more money with lower expenses.
These are some of the tools I use and hopefully at least one thing can help you.
Best of luck,

p.s. For you Wikipediacs, there is an upcoming conference in Egypt July 17-19, 2008 for people who contribute to Wikipedia. I use Wikipedia at least twice a day to find information on whatever I am researching.
