Does My Online Store have Duplicate Content?
Google is all over duplicate content, your site will suffer for it. But what exactly is duplicate content? The biggest problem is, Google doesn’t always tell you there is a problem, you can set up Google Alerts on your domains and addresses, but that’s no help for code, and template duplication. So I will try to cover the most popular ways to get pages excluded from main search for duplicate content.
- Your site uses both plain http://website and http://www.website URL protocol. Use a redirect or mod rewrite to fix this. This canonical redirect will help Google understand that the www & non-www are NOT 2 separate pages. You see, urls are like phone numbers, unique for every user… So Google thinks these 2 versions of your domain’s urls are in fact different numbers, so to speak.
- Your site has no standardized handling method for the entry page, or default indexing. This means the index/default/main page can be viewed live & independently of the www.mysite.com. You fix this with a 301 or permanent redirect. For example /index.html is exactly the same page as your domain url.
- If you use a template, this dramatically increases th opportunity for content duplication by using dynamic site elements across many or all pages. To combat this, when page specific text is added, it must be ENOUGH text to make that page stand out and be unique from the other templated pages.
- Change your Meta tags and page titles for every page. This one is 100% easy and highly important. Use the <head> elements to properly describe the page and you will be fine.
- If you are going to share files across domains, link them ….yes even your own stuff can be duplicate content.
- In your Google Webmaster Tools it is advisable the you choose a preferred domain under the diagnostic tab, and by all means while you are there check out your content analysis for duplicate information Google has found in your site.
- The #1 duplication issue I see amoung the stores we analyze is product description duplication. You MUST write great unique product descriptions for your product to be successful. Using the manufacturers description creates content that is duplicate in whole or partially with every other distributer… Many time the supplier as well. I’m thinking your site is NOT the authority for this content and Google will not display your products for search.
- Your robots.txt WILL NOT block your page from being indexed… You must block them with a noindex, nofollow or other means to specifically DISALLOW indexing of these pages.
- In general when adding textual content (product descriptions), paraphrase and add rich text ….that’s really what Google wants. Unique pages perform well… Duplicate pages never show up.
- Be extremely careful with content generators, most times the content is duplicate. Try paying a college student to write the copy for you… Good investment!
We theorize that 70% of your total page must be unique. Here are a few tools to help check it:
- This tool compares any 2 pages
- This tool generates a detailed canonical report
- This tool will detect duplicate text
