For starters i'd recommend some header tags in your html e.g. <h1..6> Only use a <h1> once, but you can use the other header tags multiple times. Search engines give importance to these tags, so make sure your keywords are in there. With that said, its still equally important that you keep them human readable as it will be a turnoff for your visitors if you just have keywords in there. Also you have next to no useful content on the page. Yes I know the site is about images, but search engines love text. I'd get rid of the massive disclaimer (on the front page at least), or move it further down, and perhaps have a few interesting short paragraphs of text in there (perhaps linking to another page). This is a start for you anyway. Cheers Tim Buchalka
This disclaimer help me to increase adsense CPC. I will add h1 tagd with my key words. Thanks for your help
