My List of Market Trend and Keyword Research Tools For PPC Marketing Campaigns

Domain Monitizers
Use these sites to figure out relative websites and bid on them in your PPC campaigns.

  Alexa.com - Type in main domain; for sites that match your main keyword, you want to click on site info for that domain; it leads to another page and in the left column click on related links; those links (domains) will be related to your main keyword. Bid on them!

Misspell Scrapers - Bid On Misspelled words

SEO Techniques 

  WebWire.com - Optimize Your Site With A Press Release. I suggest using their lowest price service they offer if you use their paid service submission. Sprinkle your targeted keywords (hopefully they're already included in your domain name as well) and you'll get a first page ranking in google. Probably a first, second or third spot on that page!

  DoFollowBlogs.com - Make comments on other blogs that have the "do follow" tag within their source code. This will allow search engines to follow backlinks from that blog. Look for the "U Comment I Follow" graphic or other sites like this one.

Article Directories - Write Articles To Generate Traffic

  SocialMarker.com - Social bookmark each article you submit to further increase the chances of your articles ranking high in the search engines.

Other Tools

  Zamzar.com - FREE Online file conversion tool. Example: convert a pdf file into a word doc to edit then convert it back to a pdf.
