Linked In Caching Madness

30th November 2012
Categories: caching, social media

It has been brought to our attention recently that if you share a link using "Linked In", it will cache the title and descrption of that link indefintely, so that if someone else shares it two years later and has made significant changes, the "preview" given by Linked In, which includes the page title, won't have changed from two years ago!

Say I share a link today to Green Living Energy's blog post on the new Electrical Safety Register, http://www.greenlivingenergy.co.uk/the-electrical-safety-register-.  The "window title", a.k.a. "meta title" of this page is "The Electrical Safety Register".  

So far so good.  

If in two years Green Living Energy have deleted their blog and post a damning indictment of the Electrical Safety Register, entitled "How the Electrical Safety Register has failed" (not likely but bear with me), and happen to post it under the same URL, i.e. http://www.greenlivingenergy.co.uk/the-electrical-safety-register-, and I want to share it on linked in, it will come up with the title in bold underneath my link "The Electrical Safety Register".  It won't check the title, despite the fact that it was first shared over 2 years ago.

Not a genius bit of programming - but forewarned is forearmed!
