We just ramped up the number of social media fields that sellers can display on their profile. Previously, we had two slots: home page and facebook. Now we've added 3 new fields: instagram, youtube and twitter.
If you previously had used one of these social media sites as your home page, we've moved that into the appropriate field. That includes 486 sellers using instagram, 343 with facebook, and 46 with youtube. Interestingly no one used Twitter as their home page.
All sellers should go and update their profile with these additional fields now to give buyers the full picture of their presence.
This covers the vast majority of the links used by sellers. If you have a presence on some other website that isn't one of the above, you are still free to use this as your home link.
