1. Properly block search engine access: Rather than letting our algorithms determine the "best" version of a file, you may want to direct Google to select your preferred version. For example, if you don't want us to index the print version of your site's articles, you can write a directory name or regular expression in your robots.txt file to prevent Google from crawling those print versions.
2. Use 301 redirects: If you have refactored your website, please use 301 redirects (permanent redirects) in the .htaccess of your original website to redirect your users, Google crawlers, and other search engines Spiders etc.
3. Links should be consistent: Try to keep your internal links consistent; never have internal links to /page/, /page and /page/index.htm. You can reuse /page/index.htm with 301 Direct to /page/.
4. Use top-level domain names: In order for us to always use the most appropriate file version, please use country-specific top-level domain names whenever possible. It's certainly clearer to Google that example.de is German-centric content than a URL like example.com/de or de.example.com.
5. Beware of syndication: If you contribute your content to other sites, include a link back to the original article in every other site's article. Note: Even then, for a query, Google will always show what we think is the most appropriate (not banned from the site) version, which may or may not be the version you want.
6. Use the preferred domain feature of Google Webmaster Tools: If other websites link to your URL using both the www and non-www versions, you can use Google Webmaster Tools to let us know which indexing method you want. .
7. Reduce duplicate content on template web pages: Take the copyright statement as an example, you have two options. One is to have a lengthy copyright statement at the bottom of each of your pages. The other is to set up a dedicated copyright detailed statement page, and then write a very brief summary at the bottom of each page and link to the copyright statement page.
8. Avoid publishing pages without content: Users don’t like to see pages without actual content. Try to avoid empty shelf pages. Take real estate web pages as an example. Do not publish (or at least block) review web pages without reviews, or real estate listing websites without real estate listings, etc. Only in this way, website users (and Google crawlers) will not see endless web pages that say "Here are the listings of houses for rent that cannot be missed in [name of city]..." but in fact there are no listings at all.
9. Understand your content management system: Make sure you are familiar with how your website displays content, especially if it includes a blog, forum, or related system. Often the same content appears in multiple forms in these systems.
10. Don’t worry, stay happy: Don’t be overly disturbed by sites that search (appropriate and republish) your content. Although annoying, they are unlikely to negatively impact your presence in Google. If you can't stand it anymore, you are welcome to file a Millennium Copyright Act request to claim ownership of your content.
