Welcome to the Q&A Forum

Interlinking is when pages of my site linking to other pages of my site. Interlinking scripts are usually the ones that show users a block of links, thumbs, headers or similar tings to give them related articles, videos, etc. This method not only helps with engagement and pageviews, but also does a good SEO role.

Yes, which is why I thought the first page might be a bit more helpful as a reference point.

if you'd like to instruct Google not to crawl the URLs with that parameter, select 'No URLs' in the Google Webmaster Tools > URL Parameters section. Still, this is a guide for Google to follow and they do not always follow the rules set. Going the robots.txt method ensures that Google will not crawl those URLs.

Good question - I still have the same question. I understand the 'by choice', but find that unconvincing so far. Did you come to a solution?

What are the pros and cons for referencing all page versions in sitemap and for include just general (English/Desktop) version in sitemap? Let me clarify, you want to know the pros and cons of putting all page versions in sitemaps, or just doing the english/desktop and letting Google figure it out. List All Content in Sitemaps Pros If the sitemaps are set up in a logical fashion, this makes for an easy way to see indexation issues. You can use hreflang in the sitemaps rather than on the page. This reduces page code and ups page speed, albeit slightly. You are guaranteed that search engine will find all of the content. Cons Lots of sitemaps to make and maintain. Sitemap just main content (desktop/english) Pros Easier to maintain. Search engines are much better today at finding most versions of content. Cons Run the risk of content not being indexed correctly. Some content might not be found and indexed. You could not easily verify indexation. If any onsite code was removed that told Google where to go, then the possibility of indexation issues increase. Hope that helps answer your question!

Just for my own organization. I know that in all the Google examples, the x-default tag is at the bottom. Overall, I don't believe it makes a difference.

Well, Google say you are, and this is what it's used for The snippet from that page explains exactly what you are trying to do. https://support.google.com/webmasters/answer/189077?hl=en No, you want to self canonicalise as well - remember, each page will be seen as unique in Google's eyes. -Andy
