Hi there,

As with what Kevin mentioned, I'm not sure why would want to include dummy links in your posts. The only plausible reason I can think of is that your website is teaching HTML or you are creating dummy design pages.

If you would like to ensure your posts are SEO optimised, you may want to include a rel="nofollow" tag in these dummy links, while linking them to actual websites that of irrelevance (e.g. linking to Google or an internal link). Adding this tag will tell search engines not to follow this link, which thereby won't affect your pagerank. This should help you get started if you have not used the tag before: https://support.google.com/webmasters/answer/96569?hl=en

Hi Bill,

Google claims that this shouldn't be an issue "as long as the content is for different users in different countries. But if you're not careful about this, it will affect your pagerank if search engine crawlers treat your content on both sites as duplicates, since most of them are looking for original content.

To be on the safe side and help search engines understand better, you should include a rel="canonical" link in pages that have same or similar content. Once detected, Google will only index one of the versions for their search results. Here's a guide from Google that will help you: https://support.google.com/webmasters/answer/139394

Hope that helps!
