It's admirable that with FAA's rich pins all 3 possible links take you back to your image on FAA. But if someone were to use the search bar, for say 'sunrise' or 'sunset', it takes them out of your gallery and to ALL sunrise sunset images on FAA. If your not on the first pages there, who knows if the potential buyer will return to your work.
The process I use to post to Social Media is this:
The 1st SM site I bring up is G+ (even if I'm not going to promote to there).
I copy and paste all the written information below the image which looks, for example, like this:
Abbey Road Sunrise Photograph by Jo Ann Tomaselli - Abbey Road Sunrise Fine Art Prints and Posters for Sale
jo-ann-tomaselli.artistwebsites.com
This can then be pasted into Pinterest, G+, SU & FB and will link back to your AW Gallery. The beauty of this is that if the search bar is used, it searches within your AW Gallery. The only thing missing is the price.
Hope this helps for those of you who want to keep promoting from your AW Gallery :-)
