Looking for our site link in Google list with specific keyword

As you know in Search Engine Optimization World, we often need to locate our site in Google list in relation of our keyword. First, we enter our keyword to google search and track page by page until we find our site. What if our site link can be found in next 40 page? Of Course we can use special search keyword format supported by google search specification, but not each of us know about it. So, I write code to crawl the keyword page by page as you wish, then give all result so we can easily using find button (Ctrl-F) to finding sentences we need. Free of charge of course. But, I need feedback to make this software better. You can reach my software at http://dyavacs.info and leave message from Contact Page. Enjoy it!
