I have a wallpaper site for about 1 year nor, receiving decent traffic from Google. Last week I have added new pages to my website after a few months break. Google bot has visited them, but it has been more than a week and they still don't appear in Google cache. There are about 7 backlinks for that pages that show up in msn, but for some reason Google doesn’t index them. Here is a sample url that has been added but doesn't shows up in Google : http://www.stylexp.ro/widescreen/1280x800-widescreen-wallpapers.html Any advice to make Google cache them?
Maybe add a few extra internal links pointing to them to make sure Google gets the picture. (edit: actually the links you have look fine, probably just needs more time) Still, it's only been a week so I wouldn't worry too much.
I show that you have a good deal of pages cached. Make sure that all of you images have a distinct alt property set to them.
