Should I delete 'data hightlighter' mark-up in webmaster tools after added schema.org mark-up?

[saultienut]

LEDSupply.com is my site, and before becoming familiar with schema mark-up I used the 'data-highlighter' in webmaster tools to mark-up as much of the site as I could.  Now that Schema is set-up I'm wondering if having both active is bad and am thinking I should delete the previous work with the 'data highlighter' tool.

To delete or not to delete?  Thank you!

Where have you added schema markup? What pages?

After briefly scanning a few pages on your site, I'm not seeing any code from schema.org in the page source. Has this been implemented/gone live yet?

only on the product pages. it's live.

Ah, ok. My mistake, I didn't drill down enough. One thing I did notice: you have authorship markup on those product pages as well. That should be removed.

According to Google's guidelines, for product pages that are not specifically written/constructed by an "author," that markup should not be there. Rel="publisher" is the only necessary markup for non-blog or article content.

The schema markup you've implemented looks good in the page source, and checks out as being correctly implemented (without any duplicates) using Google's Structured Data Testing Tool (found in Google Webmaster Tools). It appears the data highlighter markup is not causing duplicates.

I'd recommend double-checking all the product pages you've added schema to that you originally had from the data highlighter markup. There may be duplicates, there may not. To be honest, I've always gone right to schema.org, but checking for duplicates should be the only thing you should have to worry about.

Good luck!
