I am looking for tool or bot that can do the following

1. Search for footprint/keyword on Google
2. Go through each search result to find one particular url ( for example url that contains facebook.com)
3. Then go to that URL in step 2 and look for another footprint/keyword. If that footprint exists then save the url in txt file.
4. Then goto next search result and repeat step 2 & 3

This looks like Scrape Box possibility but not sure if possibe.

Thanks

Scrapebox can definitely do all this for you .

SB could but not automatically. You would need to do a search after each scrpae and set the new parameters yourself.
Even the automator addon would not quite give you this level of functionality completely "hands off"
