Here is some further information on how to attribute in different scenarios:
Websites or blogs:
The attribution has to appear on the page where the sound is being played. Either beside, above or below. You can also put the attribution in the page footer.
Put the attribution on the credits page of the app.
The attribution has to be inserted on the text/description of the post where the sound appears. On Instagram it’s better to add “Sound effects created by @yourfreesounds”.
Podcast and Online Videos (YouTube, Vimeo etc.):
Place the attribution in the video or podcast description. On YouTube for example you can put it in the video description.
In case it is an online presentation, place the attribution next to the presentation link.
SPECIAL CASE – TV, Film and Radio shows/programs, Music
productions, Commercials, Offline Presentations, Live Shows, Theatrical
performances, Conferences and Exhibitions:
Since none of these can link to a website, a backlink attribution is impossible. Therefore you need to either subscribe to a YFS PRO membership (cancellable at any time!) or purchase the sounds individually in high quality.
