"the study revealed that the lifespan of a post is nearly 24 times the currently accepted measurement of 30 days"

"The study found that only after two years will a blog post obtain 99 percent of its impressions. Only then, or by calculating for that timeframe, can true value be determined."

"In addition to a blog’s lifespan, the study revealed that a blog post goes through three distinct “life phases,” further contradicting the historical use of a 30-day measurement period."

"A 700 day lifespan indicates that blog posts are an annuity that provide value over a significant timeframe."

"The study found that by day 700, a blog post will receive 99 percent of its total impressions."

"Shout: The “Shout” phase yields an initial steep spike in impressions that occurs within the first week to ten days, when 50 percent of a blog post impressions are generated."

"Echo: The “Echo” phase begins shortly thereafter and lasts until day 30, when 72 percent of blog post impressions are realized."

"Reverberate: The third, and likely least studied, phase in a blog post’s life cycle is the “Reverberate” phase."

"This phase makes up the 28 percent of remaining impressions and lasts from day 30-700."
