Is there any online tool to check which page your site is located for a certain keyword instead of having to click the page navigation at the bottom?
If you are using firefox I recommend Free Firefox Rank Checker - Check Your Google, Yahoo!, and Microsoft Search Engine Rankings | SEO Book.com very great add on
Just add all the keywords your targeting and it will check all of the serp locations across 3 engines.
Just be sure to setup the speed to query like every 10 seconds and run it once a day or you will get temp bans from the engines.
If only want an online one this one isn't to bad Google Pagerank check SERPs + keyword trend + position tracker
I would also highly recommend this software Free Monitor for Google - search engine position and web ranking software
It is only for Google, but it is extremely effective and has all the functionality needed.
To know everything about a website or webpage use SeoQuake Toolbar.
