  Francisco José Álvarez Rubiño: I have a doubt with the SEO for images of a same thing, so I mean:
  
  ¿What "Alt" tag may I use for each photo/image when I have 4 photos for the same thing?.
  
  Example: I have an apartment for sale in Madrid, and have 4 photos for the kitchen of the apartment. What about the "Alt" tag for each photo if all them are about the same place?
  
  Option 1
  
  "Alt" tag for photos 1, 2, 3,4: "Kitchen of apartment for sale in Madrid"
  
  Option 2
  
  "Alt" tag for photos 1, 2, 3,4: "Kitchen of apartment for sale in Madrid"
  
  Option 3
  
  "Alt" tag for photo 1: "Electrical appliances"
  "Alt" tag for photo 2: "Kitchen"
  "Alt" tag for photo 3: "Oven"
  "Alt" tag for photo 4: "External view kitchen"
  
  What's the best (or the less bad) option to take?
  
  Thanks mates!

  Ryan Cramer: Opinions 1 and 2 look the same. I would do a combination of 1 and 3 . For example "kitchen of apartment for sale in Madrid - electrical appliances " to get your main keywords and a distinctive keyword in your alt phrase to improve indexing
