A year after Rollyo deployed/introduced the concept of custom Searchrolls, google does a me-too with the mouthful Google Custom Search Engine – a searchroll of sorts that folks can customise for their needs.
Difference of course is that Rollyo is powered by yahoo’s search engine and the functionality is geared towards creating custom topic searches that includes your favourite site. Google’s version is a much broader and more functional deployment where you can integrate its search tool into your own site and provide a more granular level of control.
Both of course don’t compete head-on so I expect different people will use it according to their particular needs. As always we can probably expect more innovation from the users – would love to see where this goes. One more mashup tool to add more value to your offering.
