It looks plain silly (and fun) in the first glance – you get the result of previous search. Perhaps it’s in the spirit of the coming Halloween. But, I suppose there are 2 ways to exploit this unique feature:
1. Free Marketing! Google your name, your product name, your corporate name a million times, and a million other people will get to see it. That’s provided your names are on top of the search result! Get the idea?
“A million search, you said? How to achieve that?” Well, I suppose if you know how to programmatically host a web browser component, or make a HTTP POST request, it might work. Need to research the details, though. And fyi, it is evil.
2. Cataloguing the keywords used for searches. Some search keywords proved to be online real-estate, where advertisers pay a handsome amount for it so that their products appear first in search engine results. And which keywords that users sought most? Of course there are many options for this, but isn’t it better if you have 1 more source of reliable data?
Why it can work?
A quick Googling on “Mystery Google” (exact match) showed that it has “about 410,000” results. So, at least 410,000 people has known this site. Times with the number of readers to the site, times with the number of search on the site. Easily get to millions, i guess.
A proper research need to be done here.
