This Is Why Your Website Is Slow

Ghostery releases its annual list of common embeds, including widgets and analytics, that can slow websites to a crawl.

Ghostery, the browser plugin that allows its users to “track the trackers,” just released data on the tags, widgets and analytics on websites that are the worst in terms of slowing page loads to a crawl.

Update: Ghostery discovered an error in their original data set. It appears that Millenial Media was not on this year’s list at all, and the #2 slot belonged to AdFunky. Both the text and the graph above have been changed to reflect this.

Any webmaster worth his or her salt already knows that slow page loads adversely affect Google rank and pageviews, but not everyone seems to have gotten the memo.

Ghostery estimates that if you put all of the top 10 worst “lagtags” on a single website, it would add 22 seconds to its load time.

And while the worst offender on the list, “Avalanchers” appears to be a fairly spammy link-sharing network, number two on the list, Millenial Media, appears to be a reputable “mobile advertising network” with a long list of top-tier clients, including Warner Brothers, McDonald’s, and Chrysler.

Targeted advertising firm AdFusion also made the list, slowing page load times by nearly two seconds. (An eternity in user-perceived web time.)

Rounding out the rogue’s gallery of laggy tags, hosting provider to the masses GoDaddy will charge you $3 a month to slow down your site with its Analytics package. I believe P.T. Barnum had a thing or two to say about that.

Five poems about the mind

DREAM VENDING MACHINE I feed it coins and watch the spring coil back,the clunk of a vacuum-packed, foil-wrappeddream dropping into the tray. It dispenses all kinds of dreams—bad dreams, good dreams,short nightmares to stave off worse ones, recurring dreams with a teacake marshmallow center.Hardboiled caramel dreams to tuck in your cheek,a bag of orange dreams…

I taught myself to lucid dream. You can too.

We still don’t know much about the experience of being aware that you’re dreaming—but a few researchers think it could help us find out more about how the brain works.

Is everything in the world a little bit conscious?

The idea that consciousness is widespread is attractive to many for intellectual and, perhaps, also emotional
reasons. But can it be tested? Surprisingly, perhaps it can.
