Welcome to the Q&A Forum

Cesare has provided an excellent answer here IMO, I like the suggestions for other markups to target. I also strongly agree with finding a plugin to implement this markup, it will save you a lot of time. In addition to his answer, here are a few other resources that I feel will help: BreadcrumbList Schema Page: Find information on the different properties that you can include with this particular markup as well as an example that you can model your breadcrumb schema off of. Structured Data Testing Tool: Use this tool to validate that your schema markup is free of errors. Hope these help!

Hi! I personally like to use the service of Kraken.io. Check their pricing, but I'd say it is a low cost and efficient way to handle the images. We have been using it with their magento extension. But they also have a plugin for Wordpress. (https://kraken.io/plugins) I know, it is not the only solution, but it worked well for me Good luck!

Hi there, Our UK-based company was facing this problem a while ago and we decided for the first option. Originally we had .com + /uk +/us and what we decided to do now is: we are keeping .com (we changed /uk to .com - it became our global) and the /us remained the same. We have hreflang tags. Basically, from the point of view of SEO, you might already have a strong site that will outperform the /au. Especially if you have a number of backlinks, you might drop in performance, you are right. The 301s won't help either. To keep it simple, I would go with what you have - you have started your journey and you might be pretty established there. Have a look at how you can improve your existing site further and don't risk the drop. I would keep the .com - I am saying it from the point of view of a global company launching in the US that can't afford any mistakes. I hope this helps. Good luck! Katarina
