Welcome to the Q&A Forum

I'm a newbie with SEO and I have a question regarding product descriptions. Let's say I am selling 100 dog id tags. The tags are all made of same materials, same size, just different designs. Now for the product description, do I need to write a different set of description for all 100 tags? This is an example of a short product description(there's more) for all the pet tags: Personalized with 4 lines of information and 20 characters in each line. Lifetime guarantee - If your pet ID tag ever becomes illegible, we will replace it free of charge. Solid one-piece construction - No glued or ""sandwiched"" materials to wear out or fall apart. Split ring for collar attachement included with EVERY tag. Countless uses - School backpacks, luggage, fashion accessories, and many more! All of the above information pertains to all the pet tags. Can all my product descriptions contain that information, or will I need to modify this 100 times for each individual pet tag? I read up a lot on duplicate content so I am slightly confused. Will this hurt my SEO? Thanks, Keith
