I require a program I can use in which I provide a website URL and up to 3 target words. I want the program then to crawl the target url and only record pages that contain one or more of the target words. It need it to then make the sitemap available for me to download. It should work very efficiently.
Please outline if there are any other costs or resources required in developing this. I have a web hosting service I could put it on and run it from.
