I used Traffic Power's search engine placement service and got great results. I highly recommend it if you are looking for search engine placement. Here is an explaination of the services taken from their Website:

At Traffic-Power.com we use our expertise and technological know-how to get you top search engine placement.

1. Keywords: A professionally trained technician is assigned to your account to help you choose the 20 keyword phrases that best reflect the main focus of your site.

2. 280 Attractions Pages: We build 280 individual HTML attraction pages that attract the search engines for your targeted keywords. The attraction pages are designed using a computer-generated analysis to conform to the ranking criteria of the top search engines. These pages provide spider food for the search engine spiders that includes significant unique content relating to your site.

3. Attraction Page Updates: Search engines frequently change their ranking algorithms so we update and change all client attraction pages as needed.

4. Meta Tags: We arrange the meta tags on your website to maximize visibility and placement. A meta tag is a special HTML tag that provides information about a Web page. Unlike normal HTML tags, meta tags do not affect how the page is displayed. Instead, they provide coded information analyzed by the search engines when building their indexes.

5. Directory Submission: We manually submit your site to Web directories such as The Open Directory Project. We do not manually submit to spider-based search engines because recent studies indicate that these types of search engines give preference to sites their spiders find through links. Since submission to spider-based search engines can actually hurt your ranking we create link popularity for you and then allow the spiders to find your site through those links. It generally takes around eight weeks for the search engine spiders to find and incorporate sites into their database.

6. Link Popularity: Link popularity is the total number of Web sites that link to your site. Since many search engines now use link popularity in their rankings, we use systems developed by our programmers to build your link popularity. These include adding your site in our exclusive themed link pools, submitting your site to thousands of link sites weekly, and other automated link popularity building strategies.

7. Online Reports: You can track your Web site's progress and keyword positioning with real time reports available 24 hours a day, 7 days a week. Our online client reporting system produces a current search engine placement report, link popularity report, and website activity report for daily tracking of your site's performance.

8. Customer Support: We offer free, unlimited customer support through our toll free customer service hotline. After your initial set up, our friendly support staff can help you amplify your results by suggesting design changes for your homepage and helping you to analyze your keyword performance.

Traffic-Power.com provides a complete placement strategy and a unique Business Opportunity that will bring you traffic through technology.
