...other than typing in your keyword and trawling through the listings looking for your page or pressing ctrl + f and putting the url in that as you go through the list?
There is a tool known as SEO Elite that I use to do it for me, if you're interested check out http://www.seoelite.com .
I use Traffic Travis Pro. I keep a list of keywords for a URL and run the tool monthly to check. I use it for any site URL including competitors. This works for Google, Yahoo, and Microsoft SERPs.
There are loads of online tools for checking search engine result placements (SERPs). Just do a search for "serp checker", or "seo ranking checker". Edit Just looked at Traffic Travis - looks pretty good. Thanks for the tip.
There are lots of tools. I use Google webmaster tool. I think they are more accurate than all the other third party tools. above all it is free, so why not use it?
Rank checker from seobook.com seems to be the best available rank checker tool. It comes as a mozilla addon, here it is http://tools.seobook.com/firefox/rank-checker/ hope it helps...
Most of the free tools require typing in the keywords and URLs and then waiting for the results. With Traffic Travis, it is saved as a project and running it takes less than a minute depending on the number of keywords. It also show all 3 search engines and your previous rank (when it was last updated). Just a big time saver especially when you have lots of web sites and keywords to track. Of course Traffic Travis does a LOT more than just checking your rank!
