i know google takes out sites that abuse like putting a million times belize in white text on a white background at the bottom of a page and all kinds of lil games like that. having my own spider now i know why. it just ruings your results. so overuse of keywords will get one flat booted nowadays.
here's the how to page at google. pay attention to things to avoid. they mean it.
How do I add my site to Google's search results?
Inclusion in Google’s search results is free and easy; you don’t even need to submit your site to Google. Google is a fully automated search engine that uses software known as "spiders" to crawl the web on a regular basis to find sites to add to our index. The vast majority of sites listed in our results are not manually submitted for inclusion, but found and added automatically when our spiders crawl the web.
To determine whether your site is currently included in Google’s index, just perform a search for your site's URL. For example, a search for [ site:Google.com ] returns the following results: http://www.google.com/search?hl=en&q=site%3Awww.google.com+
Although Google crawls billions of pages, it's inevitable that some sites will be missed. When our spiders miss a site, it's frequently for one of the following reasons:
- The site isn't well connected through multiple links to other sites on the web.
- The site launched after Google's most recent crawl was completed.
- The design of the site makes it difficult for Google to effectively crawl its content.
Our intent is to represent the content of the internet fairly and accurately. To help make this goal a reality, we offer guidelines for building a "crawler-friendly" site. Our guidelines are located at http://www.google.com/webmasters/guidelines.html.
While there are no guarantees that our spiders will find a particular site, following these guidelines should increase your site's chances of showing up in our search results.
THINGS TO DO
Provide high-quality content on your pages -- especially your homepage. This is the single most important thing to do. If your pages contain useful information, their content will attract many visitors and entice webmasters to link to your site. In creating a helpful, information-rich site, write pages that clearly and accurately describe your topic. Think about the words users would type to find your pages and include them on your site.
Make sure that other sites link to yours. Links help our crawlers find your site and can give your site greater visibility in our search results. When returning results for a search, Google combines PageRank (our measure of a page's importance) with sophisticated text-matching techniques to display pages that are both important and relevant to each search. Google counts the number of votes a page receives to determine its PageRank, interpreting a link from page A to page B as a vote by page A for page B. Votes cast by pages that are themselves "important" weigh more heavily and help to make other pages "important." Please note that ranking of sites in our search results is completely automated, and we do not manually assign keywords to sites.
Build your site with a logical link structure. Every page should be reachable from at least one static text link. If certain areas are not linked, you may be excluding older browsers, some users, and Google.
Consider creating static copies of dynamic pages. Although the Google index includes dynamic pages, they comprise a small portion of our index. If you suspect that your dynamically generated pages (such as URLs containing question marks) are causing problems for our crawler, you might create static copies of these pages. If you do, don't forget to add the dynamic pages to your robots.txt file to prevent us from treating them as duplicates.
Consider creating and submitting a detailed Sitemap of your pages using Google Sitemaps. Google Sitemaps is an easy way for you to submit all your URLs to the Google index and get detailed reports about the visibility of your pages on Google. With Google Sitemaps, you can automatically keep us informed of all of your current pages and of any updates you make to those pages.

Don't fill your page with lists of keywords, attempt to "cloak" pages, or put up "crawler only" pages. If your site contains pages, links, or text that you do not intend visitors to see, Google considers them deceptive and may ignore your site.
Don't feel obligated to purchase a search optimization service. Some companies claim to "guarantee" high ranking for your site in Google's search results. While legitimate consulting firms can improve your site's flow and content, others employ deceptive tactics in an attempt to fool search engines. Be careful; if your domain is affiliated with one of these deceptive services, it could be banned from our index.
Don't use images to display important names, content, or links. Our crawler doesn't recognize text contained in graphics. Use ALT tags if the main content and keywords on your page can't be formatted in regular HTML.
Don't create multiple copies of a page under different URLs. Many sites offer text-only or printer-friendly versions of pages that contain the same content as the corresponding graphic-rich pages. In order to ensure that your preferred page is included in our search results, you'll need to block duplicates from our spiders using a robots.txt file.

Will participation in AdWords or AdSense affect my listing in Google's free search results?
Google's advertising programs are independent of our search results. Search results display on the left side of our results page; ads appear on the right and in the colored box at the top.
Participation in an advertising program doesn’t positively or negatively affect inclusion or ranking in the Google search results. Inclusion and ranking are free services; we don't accept payment to expedite inclusion or improve a site's ranking for particular keywords.
Google searches more sites more quickly, delivering the most relevant results.
Google runs on a unique combination of advanced hardware and software. The speed you experience can be attributed in part to the efficiency of our search algorithm and partly to the thousands of low cost PC's we've networked together to create a superfast search engine.
The heart of our software is PageRank™, a system for ranking web pages developed by our founders Larry Page and Sergey Brin at Stanford University. And while we have dozens of engineers working to improve every aspect of Google on a daily basis, PageRank continues to provide the basis for all of our web search tools.
PageRank relies on the uniquely democratic nature of the web by using its vast link structure as an indicator of an individual page's value. In essence, Google interprets a link from page A to page B as a vote, by page A, for page B. But, Google looks at more than the sheer volume of votes, or links a page receives; it also analyzes the page that casts the vote. Votes cast by pages that are themselves "important" weigh more heavily and help to make other pages "important."
Important, high-quality sites receive a higher PageRank, which Google remembers each time it conducts a search. Of course, important pages mean nothing to you if they don't match your query. So, Google combines PageRank with sophisticated text-matching techniques to find pages that are both important and relevant to your search. Google goes far beyond the number of times a term appears on a page and examines all aspects of the page's content (and the content of the pages linking to it) to determine if it's a good match for your query.
Google's complex, automated methods make human tampering with our results extremely difficult. And though we do run relevant ads above and next to our results, Google does not sell placement within the results themselves (i.e., no one can buy a higher PageRank). A Google search is an easy, honest and objective way to find high-quality websites with information relevant to your search.
