Is there any tool for checking ranking of a keyword?

It's a common approach to check the ranking of a keyword manually. But I wonder is there any tool available i.e just paste the keywords and it will show the rankings. I googled a bit but wasn't able to find something valuable.

The Google keyword tool suggests keywords and gives the search volume for them.

I assume you want to check the search result ranking for a web site, there are tools that automate checking the search results for a list of keywords, be aware Googlg starts asking for capchas after too many queries, better to check a small list of keywords at a time or have a proxy list.

You could use for example either the free rankchecker for firefox tools.seobook.com/firefox/rank-chec... or the rankcheker in the free evaluation version of SEO Powersuit www.link-assistant.com/rank-tracker... to generate a search ranking report for the list of keywords, the latter has some other analysis functions.
