Google is not offering feeds to their search results (besides Google Custom Search) and new API keys are no longer available, what’s a web publisher to do?
Ionut Alex looks at SOAP API (Not from Google) which scrapes Google SERPs in order to produce Google API like results:
Until Google decides it’s a good idea to provide search feeds or a new API, some “evil” people came up with Evil API, a replacement for Google SOAP API, and Evil RSS, a way to get feeds for search results. Both solutions are open source and use screen scraping (what else?) to get the results from Google. That means the solution is not quite OK if you look at Google TOS:
“You may not send automated queries of any sort to Google’s system without express permission in advance from Google.”
