History
The Visibility Scorecard was introduced by SearchForecast as a means to analyse the search engine visibility of the top global websites. The first Visibility Scorecards looked at 16 factors including Meta tags that described a website, frames and flash files that hide navigational links and file formats that were readable and indexable by search engines.
Today, the Visibility Scorecard looks at over 50 factors, including code efficiency, spider crawl times, the presence of tracking code, absolute positioning techniques and the presence of external Javascript and Cascading Style Sheets files.
