Google up to date it’s Customized Search Engine (CSE) to v2 as of final weekend. As a webmaster, that is excellent news all-around. The brand new model options an improved management panel that mechanically makes modifications to the search user-interface with out requiring updates to your site-specific code. Beforehand, all web page parts would load concurrently which precipitated a short drop in website efficiency. To repair this Google has modified search web page component loading to be asynchronous, or to load individually. Consumer-side widgets can now even be custom-made utilizing the HTML syntax discovered on this web page.
CSE v1 will stay supported for a while, however when you use this Google service to your web site you must head over and replace sooner quite than later.
