Hi all, from my experience of search engine optimization, to measure its performance is very necessary and a keyword tracker should help. I tried DP's own free tracker and several others, either they need script parking on your own server, or they charge. It is understandable because normally SE like google only allow limited number of query from same IP daily. However, I made a free keyword tracker for my own usage with some tricky tech and I think I can share it without any lossing. Here it is http://theserp.com/tracker.php and any suggestion is welcome.
