Welcome to the Q&A Forum

We are about to migrate a large website with a fair few images (20,000). At the moment we include images in the sitemap.xml so they are indexed by Google and drive traffic (not sure how I can find out how much though). Current image slugs are like:
http://website.com/assets/images/a2/65680/thumbnails/638x425-crop.jpg?1402460458 Like on the old site, images on the new website will also have unreadable cache slugs, like:
http://website.com/site_media/media/cache/ce/7a/ce7aeffb1e5bdfc8d4288885c52de8e3.jpg All content pages on the new site will have the same slugs as on the old site. Should I go through the trouble of redirecting all these images?

We have a website with around 40 product pages. We also have around 300 pages with individual ingredients used for the products and on top of that we have some 400 pages of individual retailers which stock the products. Ingredient pages have same basic short info about the ingredients and the retail pages just have the retailer name, adress and content details. Question is, should I add noindex to all the ingredient and or retailer pages so that the focus is entirely on the product pages? Thanks for you help!

We have two sites, 1 in new zealand: ecostore.co.nz and 1 in Australia: ecostoreaustralia.com.au Both sites have been assigned with the correct country in Webmaster tools Both site use the same urls structure and content for product and category pages Both sites run off the same server in the US but have unique ip adresses. When I go to google.com.au and search for: site:ecostoreaustralia.com.au I get results which google says are from the Australian domain yet on closer inspection it is actually drawing content from the NZ website. When I view a cached page the URL bar displays the AU domain name but on the page (in the top grey box) it says: _This is Google's cache of http://www.ecostore.co.nz/pages/our-highlights. _ Here is the link to this page: http://webcache.googleusercontent.com/search?q=cache:Zg_CYkqyjP4J:www.ecostoreaustralia.com.au/pages/our-highlights+&cd=7&hl=en&ct=clnk&gl=au In the last four weeks the ranking of the AU website has dropped significantly and the NZ site now ranks first in Google AU, where before the AU site was listed first. Any idea what is going wrong here?
