I started developing an small perl script to parse Google results about 5 years ago. Then the number of clients and projects rises and we make an small team to go forward with this start-up.
In the last years, we improved our system a lot, having different clients with particular requirements and developing specific solutions for each of them.
Now we have a much more complex system that allows us to do unlimited queries to Google, other search engines and web sites. These amounts of information, paired with data mining techniques, have a great value for SEO, business intelligence, internet marketing and much more.
