Following these guidelines will help Google find, index, and rank your site, which is the best way to ensure you'll be included in Google's results. 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. Once a site has been removed, it will no longer show up in results on Google.com or on any of Google's partner 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.
- Offer a site map to your users with links that point to the important parts of your site. If the site map is larger than 100 or so links, you may want to break the site map into separate pages.
- Create a useful, information-rich site and write pages that clearly and accurately describe your content.
- 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 small.
- Keep the links on a given page to a reasonable number (fewer than 100).
- Allow search bots to crawl your sites without session ID's 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.
- Make sure your web server supports the If-Modified-Since HTTP header. This feature allows your web server to tell Google whether your content has changed since we last crawled your site. Supporting this feature saves you bandwidth and overhead.
- Make use of the robots.txt file on your web server. This file tells crawlers which directories can or cannot be crawled. Make sure it's current for your site so that you don't accidentally block the Googlebot crawler. Visit http://www.robotstxt.org/wc/faq.html for a FAQ answering questions regarding robots and how to control them when they visit your site.
- If your company buys a content management system, make sure that the system can export your content so that search engine spiders can crawl your site.
When your site is ready:
- Once your site is online, submit it to Google at http://www.google.com/addurl.html.
- 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!.
- Periodically review Google's webmaster section for more information.
