Some – but not all – ‘content farms’ have lost out through Google’s latest update, but real sites that generate real news and information are among the losers too, says new research An analysis by Sistrix , an independent company that looks at how sites rank against huge numbers of common search keywords, has revealed more than 300 sites that have lost out from Google’s re-ranking of sites for “original content” (or the lack of it) . Among the names are well-known sites such as: • the British Medical Journal , the respected medical resource • Cult of Mac , which provides Apple news and interviews; • Daniweb , a big IT discussion site; • Digital Trends , a tech news site • Mahalo , the “human-mediated” search engine backed by entrepreneur Jason Calacanis; • PR Newswire , which pumps out press releases on behalf of companies, and so is often a mirror of what appears elsewhere, on companies’ sites; • Robtex.com , which offers domain details on sites, and is a handy tool if you’re trying to find out who is cohosted on a suspected spam site; • Slideshare , used to share presentations online; • Songkick , which alerts fans to when their favourite band is heading to town; • Technorati , the once-great, now-fading blog-indexer; • The Well , “the birthplace of the online community movement” • Wikinvest , a web startup that tries to challenge Yahoo and others by letting you track stock portfolios. (The full list from Sistrix is at the end of this post.) Sistrix looked at more than 60m domains across six countries: each week it tries searches for 1m most commonly used search engine keywords and looks at where sites rank.
