Din cate probabil stiti, google indexeaza mult mai multe informatii decat vedem in motorul de cautare in mod obisnuit. La aceste informatii se adauga si metadata din imagini. Am observat asta cautand in google images dupa niste tag-uri si am examinat o imagine sa vad pe ce criteriu mi-a aparut in search pentru ca numele acesteia nu avea nicio legatura cu ce am cautat eu.
Imaginea am analizat-o cu exiftool
Sa vedem cum sta treaba.
Descarcam o imagine de pe un site oarecare:
marian@pluto:~/work/seo$ curl -o imagine.jpg http://cache.pakistantoday.com.pk/2013/05/5274-gun-fire-WallFizz.jpg

Q: What happens to the EXIF, XMP and other metadata my images contain? A: We may use any information we find to help our users find what they’re looking for more easily. Additionally, information like EXIF data may be displayed in the right-hand sidebar of the interstitial page that appears when you click on an image. Q: Should I really submit an Image Sitemap? What are the benefits? A: Yes! Image Sitemaps help us learn about your new images and may also help us learn what the images are about.
Nota: Chestia cred ca este buna daca cineva va fura tot timpul pozele facute de voi.
Il puteti da in judecata si aveti dovada clara ca pozele sunt ale voastre (prin metadata info)
Avantajul este ca puteti ridica un site web si in google images dupa anumite cuvinte cheie.
