One of my free tools for creating web pages automatically inserts a back-link to my home page as a footer, or 'badge' from the free web pages it creates. Hence there are tens of thousands of low quality sites out there linking back to my home page. While this was great ten years ago, Google looks on things differently these days. So the question is, will Google penalize me for this? Does the negative outweigh the positive - should I remove the insertion of back-link badges from the product?

Thanks,

Peter
