Hi there.... I'm still exploring SEO world and I would like to have some ideas from you on this issue.

My pages are about photos/images/pictures of AAA or BBB.

Let say that I want optimize for the keyword AAA (1) and for the keyword BBB (2) and NOT so much for something like pictures of AAA or pictures of BBB or photo of AAA or photo of BBB or similar key phrases as they have not a good popularity in monthly numbers of searches but the single words itself AAA and BBB have.

So... I want FOCUS all the maximum optimization as possible on the words AAA (1) and BBB (2) ITSELF much more then phrases combinations above…

What can I do exactly about?

Title ?
meta Description ?
meta Keywords ?

Just to clarify better make some example....

I have 'Milan' (AAA keyword)
I have 'Lombardia' (BBB keyword)

I can make all keyphrase possible using other common words like images, photos, photography, pictures and so on...

My goal anyway is to rank for... AAA or BBB or both but not really care to rank on keyphrase as they have not so much a popularity search index.

Ideas???

usual things like title, meta, h1, internal linking, link keywords should help.
