• 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 behaviour, 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 affiiate programmes with little or no original content.
• If your site participates in an affiiate programme, make sure that your site
adds value. Provide unique and relevant content that gives users a reason to visit your site fist.
• Avoid link farms and focus on attracting quality, valuable links.
