if your PR is high it is possible with good keyword and description.
It's probably better to optimize for two word keywords like "Art Gallery" or "photo gallery".
Then, follow these steps:
1, Put the keyword in your page title;
2, Put the keyword in the keywords Meta tag;
3, Have the keyword in a H1, H2 and H3 title in another expression, for example, "The best Art Gallery";
4, Have the keyword a number of times in the text, especially in the first sentence;
5, Have the keyword in a link to another page in your site which links back to your front page;
6, Have an RSS feed on your page for that particular keyword so that your page will be up-dated daily;
7, Get links, from other sites, to your site, with the keyword in the link text.
Yeah, forget about trying to rank for a single keyword. Besides it doesn't make much sense because it won't bring in targeted traffic. 'Gallery' could mean anything from a shooting gallery to 'Gallery hotel' to photo gallery to whatever. You'll want to get much more specific. As mentioned before, you'll need to make a list of 2 or 3 word keyphrases and then do some in depth market research. Find out how stiff the competition is, which keywords (keyphrases) bring in the most traffic, how much traffic each keyword brings in, et cetera.
Have you used any of this information, sambhav?
Thanks for the information. I will update that site later but all this was very much useful and I am making my new website considering all this.
