I guess if I use keywords as title of pages it would be useful and I can use keywords in the content and text but there is a problem. My site is a photo gallery of my works and titles of photos are different and without any relation with useful keywords for a photography site. For example tilte of a photo is "Clever Boy" and it useless in looking for a photographic site in searching. If I choose "Fine Art Photography" for title of page (very different of title of photo) in this case it sounds bad in ranking? (my site is under construction ). I did it in my previous site and Google display page with their photo's title! and there was no visitor from Google!
