And finally I act, to provide SEO Small Letter To the point that I have outlined as follows
Dear Googlers
- Make pages primarily 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.
- 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 content.
- Make sure that your <title> elements and alt attributes are descriptive and accurate.
- Use keywords to create descriptive, human friendly URLs.
- Provide one version of a URL to reach a document, using 301 redirects or the rel="canonical" element to address duplicate content
This message is especially for you who want to avoid duplicate content, so that your content is not subject to the TOS by Google, you should be familiar with the canonical, for more details, I'll give it a way that does not duplicate content.
