The biggest change I see at Hakia.com is their Tab interface in the redesigned Search Results Page. Now Hakia provides an option to refine your search results to sites that have been gone through review by Hakia to meet strict non-commercial and credibility standards. The results from credible sites, however, are currently limited to only in the health and the environment category.
I noticed that The default SERP of Hakia has also changed, for instance now they have a three-column layout which shows Web Results, Images & Sponsored Ads.
Well, I always thought Hakia was a promising engine specially because they included Semantic Technology on their engine. However I still don’t think they have done enough to even stand near it’s competitors.
