Welcome to the Q&A Forum

Hello all, Could someone please advise on acceptable use of the availability attribute 'preorder' value in rich snippets schema markup for our websites and the Google Shopping feed? Currently all of our products are either 'in stock' or 'out of stock', also mentioned was 'available for order' but I found that in the 2014 Google Shopping update, this value will be merged with 'in stock' here 'We are simplifying the ‘availability’ attribute by merging ‘in stock’ with ‘available for order’ and removing ‘available for order’. The products which we would like to mark as 'preorder' have been in stock and then sold out, however we have a due date for when they will come back into stock, so therefore the customer can preorder the product on our website i.e. pay in advance to secure their purchase and then they are provided with a due date for the products. Is this the correct use of the 'preorder' value, or does the product literally have to never have been released before? The guidance we have is: 'You are taking orders for this product, but it’s not yet been released.' Is this set in stone? Many thanks in advance and kind regards.

Hi,
We seem to have duplicated rel=author tags (x 3) on WordPress pages, as we are using Yoast WordPress SEO plugin which adds a rel=author tag into the head of the page and Fancier Author Box plugin which seems to add a further two rel=author tags toward the bottom of the page. I checked the settings for Fancier Author Box and there doesn't seem to be the option to turn rel=author tags off; we need to keep this plugin enabled as we want the two tab functionality of the author bio and latest posts. All three rel=author tags seem to be correctly formatted and Google Structured Data Testing Tool shows that all authorship rel=author markup is correct; is there any issue with having these duplicated rel=author tags on the WordPress pages?
I tried searching the Q&A but couldn't find anything similar enough to what I'm asking above. Many thanks in advance and kind regards.

A bit of advice please, I currently use Linkdex but want to support it with a good and easy to use but powerful prospecting tool. Which would you recommend? Link Prospector or Ontolo? I want to prospect the links and put them and track them in Linkdex. I will probably also look to get a list scraper , but it seems there are some free ones about. I look forward to your advice. Thank you very much.
