All guest posts on my blog include information on the writer and/or entity who provided the content. I do not publish content and say it has been written by me when it hasn't.
Once approved all guest posts should be submitted with at least 1 high quality non-copywritten photo (i.e. from pixabay.com) to be used as a header image.
I often make minor editing adjustments and sometimes add my own personal commentary including affiliate links to related products and links to previous blog posts.
