16. A computer-implemented method performed by a credibility scoring system comprising at least one server device with a processor, the computer-implemented method for assessing credibility of a website, the computer-implemented method comprising: identifying by operation of the processor, a definition that is specified for each visual element of a set of visual elements of a particular website; tracking by operation of the processor, different definitions that are specified for each visual element of a set of visual elements that are common across a set of credible websites, wherein the set of credible websites and the particular website relate to common subject matter; computing by operation of the processor, a credibility score for each visual element of the particular website based on proximity of the definition for each visual element of the particular element to the definitions of a corresponding visual element specified by the set of credible websites; and presenting from the credibility scoring system, credibility of the particular website by rendering the particular website and presenting a credibility score adjacent to each visual element of the set of visual elements of the particular website, each credibility score quantifying an impact that a particular visual element has on overall credibility of the particular website.
16. A computer-implemented method performed by a credibility scoring system comprising at least one server device with a processor, the computer-implemented method for assessing credibility of a website, the computer-implemented method comprising: identifying by operation of the processor, a definition that is specified for each visual element of a set of visual elements of a particular website; tracking by operation of the processor, different definitions that are specified for each visual element of a set of visual elements that are common across a set of credible websites, wherein the set of credible websites and the particular website relate to common subject matter; computing by operation of the processor, a credibility score for each visual element of the particular website based on proximity of the definition for each visual element of the particular element to the definitions of a corresponding visual element specified by the set of credible websites; and presenting from the credibility scoring system, credibility of the particular website by rendering the particular website and presenting a credibility score adjacent to each visual element of the set of visual elements of the particular website, each credibility score quantifying an impact that a particular visual element has on overall credibility of the particular website. 20. The computer-implemented method of claim 16 , wherein computing a credibility score for a particular visual element comprises specifying a first value when the definition for the particular visual element of the particular website does not correspond to any definition specified for a corresponding particular visual element of the set of credible websites and specifying a second value when the definition for the particular visual element of the particular website corresponds to a definition specified by at least one credible website of the plurality of websites for the corresponding particular visual element, and wherein the second value is greater than the first value.
