Google Quality parameters

Google Quality guidelines - specific guidelines for Webmasters and SEO

* Avoid hidden text or hidden links.

* Don't use cloaking or sneaky redirects.

* Don't send automated queries to Google.

* Don't load pages with irrelevant keywords.

* Don't create multiple pages, subdomains, or domains with substantially duplicate content.

* Don't create pages with malicious behavior, such as phishing or installing 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 you determine that your site doesn't meet these guidelines, you can modify your site so that it does and then submit your site for reconsideration.
