I've posted a few times here and this is my dilemma.
So, I use a multi store setup w/ Magento and so, I manage multiple stores under one setup. The stores share a lot of things including categories, products, product reviews, product images, etc. My stores include a .com site, a .ca site, .co.uk site and .in site.
My concern how sharing effects duplicate content. It's frustrating because a lot of times other stores that I spot online will share the same stuff with other stores in their same family. For instance, Cafe Press is selling a tshirt now called "Heavy Drinker Dark" on their .com site. If you simply change the .com in the url to .ca, the exact same product reappears (same image, same description, same price) except it's in CAD vs. USD. Still, how is that NOT duplicate content?
Now, I know my site is likely small potatoes to Cafe Press and Google is probably letting them get away with stuff. I don't mean to compare myself to them, but it just got me thinking.
My current Magento eCommerce platform allows me to have custom variables and because of this, I can change the wording of html/text blocks from one store to another. For instance, when viewing my site from the .ca store, the block may say, "We offer a great selection of the items you want" and my co.uk store would say as an alternative... "Is amazing selection what you desire? Then check out our items". Again, I'm just spinning some words around to make parts of the site feel unique between store, even if it's just a block or two, but mostly what it is changing is sideboard, header and footer content.
The 500lb gorilla in the room is actual product and category descriptions! I'm talking 500+ word content about each category and/or product being sold. I say "the 500lb gorilla" because it's the only thing I'm trying hard to avoid. haha
Basically, my SEO guy is like you need fresh content per each product and category and even though let's say: test-site.co.uk/shop/item1.html is the same url as test-site.ca/shop/item1.html, the content has to be unique on each or else you risk "duplicate content" warnings. He makes it sound that I can get away with sharing the same reviews, same product images, but AT THE VERY LEAST the content or text about the item and/or category has to be unique to each shop.
My question is, how close can content be before "duplicate content" becomes an issue? In other words, just what is Google looking for? I always thought that "duplicate content" meant duplicating something like word-for-word the exact same content (verbatim) as another site, but what if the sidebars are different and the header text is slightly different but main body content is the same? Is that too similar.
I really look forwarding to getting some good feedback on this dilemma. I am in desperate need to fix my site, which lost ranking years ago after Penguin/Panda updates. I have spent so much money trying to repair the damage and although I have improved 500%, I still can't get back to page 3 or better for top keywords I desire.
My SEO guy is like, rewrite every product and category description. BUT with a lot of products, I'm looking at a thousand dollar investment or months of my site. I just want to hear from you, just how serious is this part of SEO before I sink ever last dollar into it? Can I make slight adjustments to the site or are we taking a major overhaul?
