Here's some helpful information to assist you in understanding the search engines.
First, the rules change on a regular basis! As a webmaster, part of my job is to keep up with current search engine ranking requirements.
The following is information comes from Google, the most used search engine on the web:

Webmaster Guidelines |
Following these guidelines will help Google find, index, and rank
your site. Even if you choose not to implement any of these suggestions,
we strongly encourage you to pay very close attention to the "Quality
Guidelines," which outline some of the illicit practices that may
lead to a site being removed entirely from the Google index or otherwise
penalized. If a site has been penalized, it may no longer show up in
results on Google.com or on any of Google's partner sites.
When your site is ready:
Have other relevant sites link to yours.
Submit it to Google at http://www.google.com/addurl.html.
Submit a Sitemap as part of our Google webmaster tools. Google Sitemaps
uses your sitemap to learn about the structure of your site and to
increase our coverage of your webpages.
Make sure all the sites that should know about your pages are aware your
site is online.
Submit your site to relevant directories such as the Open Directory
Project and Yahoo!, as well as to other industry-specific expert sites.
Design and content guidelines
Make a site with a clear hierarchy and text links. Every page should be
reachable from at least one static text link.
Create a useful, information-rich site, and write pages that clearly and accurately describe your company.
Think about the words users would type to find your pages, and make sure that your site actually includes those words within it.
Try to use text instead of images to display important names, content, or links. The Google crawler doesn't recognize text contained in images.
Make sure that your TITLE and ALT tags are descriptive and accurate.
Check for broken links and correct HTML.
If you decide to use dynamic pages (i.e., the URL contains a "?" character), be aware that not every search engine spider crawls dynamic pages as well as static pages. It helps to keep the parameters short and the number of them few.
Keep the links on a given page to a reasonable number (fewer than 100).
Technical guidelines
Use a text browser such as Lynx to examine your site, because most search engine spiders see your site much as Lynx would. If fancy features such as JavaScript, cookies, session IDs, frames, DHTML, or Flash keep you from seeing all of your site in a text browser, then search engine spiders may have trouble crawling your site.
Allow search bots to crawl your sites without session IDs or arguments
that track their path through the site. These techniques are useful for
tracking individual user behavior, but the access pattern of bots is
entirely different. Using these techniques may result in incomplete
indexing of your site, as bots may not be able to eliminate URLs that
look different but actually point to the same page.
Quality guidelines
These quality guidelines cover the most common forms of deceptive or
manipulative behavior, but Google may respond negatively to other
misleading practices not listed here (e.g. tricking users by registering
misspellings of well-known websites). It's not safe to assume that just
because a specific deceptive technique isn't included on this page,
Google approves of it. Webmasters who spend their energies upholding the
spirit of the basic principles will provide a much better user
experience and subsequently enjoy better ranking than those who spend
their time looking for loopholes they can exploit.
Quality guidelines - basic principles
Make pages for users, not for search engines. Don't deceive your users or present different content to search engines than you display to users, which is commonly referred to as "cloaking."
Avoid tricks intended to improve search engine rankings. A good rule of
thumb is whether you'd feel comfortable explaining what you've done to a
website that competes with you. Another useful test is to ask, "Does
this help my users? Would I do this if search engines didn't exist?"
Don't participate in link schemes designed to increase your site's
ranking or PageRank. In particular, avoid links to web spammers or "bad
neighborhoods" on the web, as your own ranking may be affected adversely
by those links.
Don't use unauthorized computer programs to submit pages, check
rankings, etc. Such programs consume computing resources and violate our
Terms of Service. Google does not recommend the use of products such as
WebPosition Gold™ that send automatic or programmatic queries to Google.
Quality guidelines - specific guidelines
Avoid hidden text or hidden links.
Don't employ cloaking or sneaky redirects.
Don't send automated queries to Google.
Don't load pages with irrelevant words.
Don't create multiple pages, subdomains, or domains with substantially duplicate content.
Don't create pages that install viruses, trojans, or other badware.
Avoid "doorway" pages created just for search engines, or other "cookie cutter" approaches such as affiliate programs with little or no original content.
If your site participates in an affiliate program, make sure that your site adds value. Provide unique and relevant content that gives users a reason to visit your site first.
If a site doesn't meet our quality guidelines, it may be blocked from the index. If you determine that your site doesn't meet these guidelines, you can modify your site so that it does and request reinclusion.
