I have c++ programming background. but I wanna make seo tool. for example: crawl and analytic a website and give me information what I need. given a list of page, query their pr or other infomation in one click. some of them are very special task, no tool avaiable ,it must be done by myself. but I do not know where to start, any one give some links or reference? thanks.
more example what I need: crawlbot(just like googlebot but more simple ) visit analytic tool(just like google analytic,yes more simple than it)
