Using https://sites.google.com/ there isn’t any widget or drop down to easily add affiliate codes.
Need a widget to place the code into header and close ad body text.
Or flexible way to add affiliate code.
Google sites ‘embed’ function doesn’t work with affiliate code outside of google, sort of useless.
Not a fan of wordpress and no need for other web builder stuff just a-google site widget for affiliate code.
Happy to support the developer or coder who comes up with one and further promote their effort.
