SEOLab—All in #1 SEO Optimizer

PLEASE DO NOT INSTALL THIS APP AND IF YOU HAVE PLEASE CHECK YOUR TAGS. I FOUND THIS WAS RESPONSIBLE FOR ADDING TAG "ISSUES" ALL EXISTING PRODUCTS IN MY STORE. TO WHO DOESN'T UNDERSTAND SUCH NAMED TAG ARE VERY HARMFULL TO THE SEO AS WHEN CRAWLING BOTS LIKE GOOGLE FIND SUCH TAG WILL AUTOMATICALLY BE FLAGGED AND WILL DE-INDEX THE PAGES AND PRODUCTS FROM MERCHANT CENTRE. I AM THANKFUL TO SHOPFY BACKEND WAS ABLE TO INVESTIGATE AND LET ME KNOW THIS WAS THE CULPRIT FOR ADDING THE TAG.

I DO UNDERSTAND HOW TAG ARE USED TO FILER THE PRODUCT WITH IN THE ADMIN FOR COLLECTIONS, HOWEVER NOT SURE IF YOU ARE AWARE THAT TAG CAN PLAY IMPORTANT ROLE WHEN WHEN COME TO SEO( SEARCH ENGINE OPTIMIZATION). IT WOULD BE FOR HELPFUL FOR USERS IF YOUR WON'T ADD TAGS ON ITS OWN. !!!! THANKS
