We offer several search based products to our customers, licensing in Software As A Service:
Site Search = we crawl a website to enable that website to add or better their own site search (self learning ranking). We do not focus on this product. If a client wants it, we can deliver.
example: http://www.europeesche.nl and use the searchbox or http://eriks.com and search
Conversion Search = product search (mainly webshops) which can be presented in a layer (example = http://www.joinedforce.nl/gsm_typeresult.htm and type a letter in the search box). This product too is self learning and takes clicks and sales into account and increase conversion and up/cross selling. Our main product.
Inline FAQ search = let visitors ask questions in natural language about the services in the page they are at and don't let them leave the process (checkout for example). Doing so will increase conversion. A top product next to Conversion Search
example: http://www.europeesche.nl/overdeeuropeesche/faq/ (dutch)
Individual Content = show products based upon the actions of the visitor showing content which is focused on him/her in a Adsense kind of way.
No example yet but a demo is available: http://joinedforce.nl/google.htm search for weber, click search and then click the first result. You'll see a bbq shop page with product suggestions on the right. If you had searched for groen (green) it would have shown other products
Two other products we have/are developing are typeresult which holds its own website (http://www.typeresult.com) but we do want to mention it and mobile shop which we want to launch later this year.
Several publications about our conversion increasing search will be published in a few weeks and the scores are very good (we did not conduct the tests ourselves).
A few months ago we had our new logo designed here and now we want to renew our website (logo and letterhead design attached to the brief as png and an eps for the logo)
