Here are a few tips on creating Google-friendly pages:

1. Always Include Relevant Content - Make sure that the content on each of your pages is relevant to your site. Many sites have various resources on a number of different topics. This is fine, as long as the overall theme for your Web site is solid. I would also suggest that you organize your related content into individual directories. Some businesses find it beneficial to organize each sub-theme of their site into a separate domain so they can cross-link the domains. If you do this, make sure you have links from other sites as well.

2. Avoid Duplicate Content - Create each page with unique content. If you are targeting different search engines for the same keyword, then you may find that you have some very similar content between certain pages. If this is the case, you can always create a robot.txt file to tell each search engine crawler not to index a page or directory that was created for another search engine.
3. Avoid Keyword Stuffing - Creating pages that excessively repeat your keyword phrase is definitely not a good idea. This almost always will throw up a red flag to the search engine and is one of the most common forms of "spamming." How many keywords are too many? See WebPosition's Page Critic for up to date, specific recommendations regarding how many words and keywords are recommended in each area of your page.
4. Design Good Looking Pages - Although Google cannot tell if your page is aesthetically pleasing, it is recommended that you create pages that look good and fit the theme of your Web site. This will definitely increase the click through rate from the arrival page to the rest of your Web site.
5. Avoid Using Hidden Image Links - Many site owners think they can fool Google by including transparent 1x1 pixel image links on their home page that point to their optimized pages. These are very small images contained in a hyperlink that are not visible to the naked eye. This can get your page dropped from Google's index.
6. Avoid using links that have the same color as the background on your page - Many site owners try to hide the links on their home page by making the text color the same as the background color of the page. As with the scenario above, this can also get your page banned from Google.
7. Avoiding using Javascript Redirection Techniques - A number of Web site owners have implemented the use of Javascript to redirect a user to another page while allowing Google to crawl the page that includes the Javascript code. This did work for a while, but Google eventually caught on. Other forms of redirection, like IP cloaking are also frowned upon by Google.
